Site Details

EXECUTIVE SUMMARY Site Address

Land at Arnold’s Field, Launders Lane, Rainham, RM13 9GJ

National Grid Reference

554116, 182008

Site Area

16.94Ha (approx.)

Form of Development

The site is understood to comprise a former landfill site that has subsequently been subject to further deposit of materials over its history. The parcel of land is noted to be undulating in nature with significant level changes, which are finished at surface level with areas of low level and dense vegetation, together with waste materials/Made Ground across the surface of the site. A compound area is located on the eastern boundary off Arnolds Lane, comprising an area of hardstanding with metal portacabin style units. The works comprised a review of desk study information, an assessment of the Source Pathway Receptor Linkages (PRA) and development of a site Conceptual Model (CSM) for the current land use. The assessment included a review of third party reports (if/where made available) and intrusive investigations including 13No. machine excavated trial pits to depths of between 3.00m and 3.40m bgl (TP101 to TP113); 18No. dynamic sampler boreholes to depths of up to 5.00m bgl (WS101 to WS106, WS106a, WS107, WS107a—c, WS108, WS108a-b, WS109, WS109a-b and WS110) with gas/groundwater installations and return spot gas and groundwater monitoring of standpipes on six occasions.

Scope of works

Encountered Conditions

Ground Conditions

Geochemical laboratory testing was undertaken on encountered soils and waters to support a contamination assessment and preliminary waste assessment for the site. It is considered that all of soils encountered across the site comprised Made Ground, with no investigation locations extending into natural soils underlying the site. The Made Ground comprised a mix of materials. The soils encountered generally comprised brown silty/clayey/gravelly sometimes ashy SAND or brown, grey or black gravelly sandy CLAY. Gravels included brick concrete, tarmac, coal, clinker and slate. Other items encountered within exploratory hole positions included tyres, plastic fragments, plastic bags, cement bags, CD players, cassette tapes, timber, slate, ceramic tiles, textiles, hessian, plastic gloves, glass bottles, cabling, ceramic pipe, plastic bottles, paper, metal bars, bike parts, packing tape, polystyrene, fibreglass, metal car parts and timber sleeper, metals drums and canisters, and Asbestos Containing Material (ACM) and/or suspected Asbestos Containing Material (ACM). Some of these encountered soils were noted to have a hydrocarbon/tarry odour (TP105, TP110 and WS107c) others were noted to have an organic odour (TP106, TP107 and TP112). Other soils encountered on site comprised greyish brown ashy gravelly SILT. Gravels are fine to coarse brick with plastic (TP103 and TP104). Domestic waste: often comprising 20% to 85% plastic bags, up to 50% gravelly SAND, gravels are fine to coarse brick and concrete and flint, 5% timber, 5% textiles. Other items included: metal pipes, plastic pipes, rope, metals cans, brick, hessian materials, cladding, cables, ceramics, plastic bottles, shoes, foam, car parts, underlay and car registration plates, cassettes, paper labels, metal, tree trunk, carpet, metal wire, plastic tray, netting, plastic bucket (TP101, TP102 and TP113). TP101 was noted to have both hydrocarbon and organic odour.

Ground Investigation Report EXECUTIVE SUMMARY Ground Conditions Cont.

Groundwater

Excavations

Human Health

Lilac iridescent colouring (thought to be connected with some form of combustion waste) comprising fine to coarse GRAVELS of concrete and clinker (TP107) which was noted to change in colour on exposure to the air, becoming more orangey/brown like rust. Surface tipped materials noted while tracking across the site: 70% plastic (mostly plastic bags), 15% textiles, metal, timber and concrete (TP111) and ACMs. During investigation works groundwater was encountered between 3.00m bgl and 4.10m bgl. On return monitoring visits groundwater has been recorded between 2.40m bgl and 4.70m bgl. During the excavation of the intrusive investigation positions instability was noted within the Made Ground in a number of locations across the site and within varying materials. TP101 at 1.20m and TP102 at 0.80m bgl were noted to be unstable within the domestic waste encountered, TP103 at ~2.30m, TP104 at ~2.10m noted localised spalling. TP105 at 3.20m TP106 at 1.80m, TP108 at ~2.1m and TP110 at 3.4m bgl noted localised instability. After TP111 had reached 3.70m the sides were noted to collapse from 0.80m bgl. TP107, TP109, TP112, TP113 were noted to be stable and excavated to depths of between 3.30m and 3.75m bgl. Instability was only encountered within the window sampler boreholes at WS109B where the position was drilled to 3.2m bgl and collapsed to 2.8m bgl. All excavations on site are likely to be unstable in the short term. Samples from site were tested for a range of contaminants including Metals, TPH, PAH, BTEX, PCBs, VOCs, SVOCs, inorganics and asbestos. Exceedances were identified for metals and PAH when compared to Public Open Space Screening Criteria. The exceedances were identified in TP103 (PAH), TP106 (lead), TP110 (arsenic) and WS107c (PAH). The risk to members of the public from these exceedances would be mitigated if the site was secured to prevent unauthorised access.

Environmental Considerations

Asbestos was identified in 9No samples sent in for analysis. Asbestos cement, loose fibrous debris and loose fibres were among the ACMs identified. It is possible that wind disturbance could entrain any loose fibres at the surface and transport them offsite in the prevalent wind direction. It is recommended that air monitoring be carried out across the site and along the boundaries to monitor for the presence of any asbestos fibres (to assess potential mobility as a result of current conditions on site).

Groundwater/leachate

Ground Gases (Excluding Radon)

Because asbestos containing materials have been identified on site, suitable assessment, planning and control measures to minimise asbestos fibre release must be employed in line with the Control of Asbestos Regulations 2012 (CAR 2012) when working with asbestos and asbestos containing soils. Water/leachate samples recorded exceedances in relation to Drinking Water Standards (DWS) and EQS Freshwater in arsenic and PAH in TP110 3.50m bgl and Boron, Mercury and Chloride in WS102 3.18m bgl. It is thought that these are likely to be isolated pockets of perched water/leachate rather than a continuous body of groundwater. The nearby surface water Common Watercourse has not been sampled due to overgrown vegetation. The spot monitoring undertaken to date detected methane at concentrations in the range of 0.0% to 33.4%. Carbon dioxide has been detected at concentrations in the range of 0.1% to 30.2% and oxygen in the range 0.1% to 22.0%. Volatile Organic Compounds (VOCs) have been detected at concentrations of between 0.0ppm to 302ppm during the monitoring visits. Atmospheric pressure was recorded in the range

Arnold’s Field, Launders Lane, Rainham, RM13 9GJ London Borough of Havering Council

Ground Investigation Report EXECUTIVE SUMMARY of 991mb to 1020mb during the visits undertaken. Borehole flows were measured and recorded steady flows between -0.2 to 1.2 l/hr. Carbon monoxide was detected at concentrations ranging between 0ppm and 12ppm, hydrogen sulphide was recorded at concentrations between 0ppm and 61ppm. It is considered that the elevated concentrations of methane and carbon dioxide identified across the site are being generated by the former historic permitted landfill located on the site. In addition, the lack of oxygen or reduced concentrations of oxygen recorded within the boreholes where elevated methane has been identified identifies a lesser risk of trommel fires in these areas.

Radon

Waste Disposal

The lack of notable flow indicates that the methane and carbon dioxide identified as being generated on the site are migrating by diffusive flow only. Therefore, it is considered, based on the monitoring undertaken to date, that there is a low migration risk of gases off site. The Groundsure report states that the site lies in an area where <1% of homes are above the Action Level as defined by Public Health England and the BGS. In addition, the BGS assessment states that no radon protective measures are required in the construction of new houses or extensions on the site. The Groundsure data utilises the recently updated Radon dataset, effective as of 1st December 2022, and is based on a 50m grid square. Although the analysis indicated that some of the soils on site were classified as nonhazardous, two samples were also found to be hazardous (TP110 3.40m and TP106 2.20m) as part of the analysis undertaken. It should be noted that analysis was only undertaken on a selection of samples recovered from the investigation from the site. It should also be noted that any extraneous materials such as plastic, wood etc present in the soils as observed could impact the waste classification. Where soils are identified to be hazardous pre treatment may render some of the materials non -hazardous. It should be noted that ACMs and trommel fines were identified on site. The presence of these materials will likely impact the waste classification of any parent soils.

Recommended Further Action • Undertake asbestos air monitoring; • Secure the site to prevent unauthorised access; • Consideration of capping of the site; • If abnormal conditions, or conditions differing from those reported are encountered, Geotechnical/GeoEnvironmental advice should be sought to determine a suitable source of action. Suggested Further Action • Undertake continuous gas monitoring for a period of 3-6 weeks across the site; • Undertake a surface emissions survey across accessible areas of the site; • Undertake additional TOC analysis of Made Ground soils across the site; • Install deep boreholes solely within the historic permitted landfill waste material. This Executive Summary is intended to provide a brief summary of the main findings and conclusions of the investigation. For detailed information, the reader is referred to the main report ref.

INTRODUCTION

1.1

General

Geo-Environmental Services Limited (Geo-Environmental) was instructed by Havering Borough Council (LBH) (the Client) to undertake a Phase I desk study and preliminary risk assessment and subsequent intrusive investigation into the geological and geo-environmental factors pertaining to Land at Arnolds Fields, Launders Lane, Rainham, Havering, RM13 9FL herein referred to as ‘the site’ to provide site specific information in relation to assessment of the site under Part 2A of the Environmental Protection Act 1990. The site’s location is presented in Figure 1. 1.2

Background

The site is understood to comprise a former landfill that has subsequently been subject to further unlicensed deposition of materials over its history. The parcel of land is noted to be undulating in nature with significant level changes, which are finished at surface level with areas of low level and dense vegetation, together with waste materials/Made Ground across the surface of the site. A compound area is located on the eastern boundary off Arnolds Lane, comprising an area of hardstanding with metal portacabin style units. The assessment is proposed to understand the environmental factors of the historic landfilling and subsequent deposit of further waste on the site and associated risks. 1.3

Objectives

The site has been subject to formal landfilling and further unauthorised deposits of waste. The site has recently been subject to a number of surface and subsurface fires. As such, works were required by London Borough of Havering Council to assess the risk from the site and in relation to the fires that have occurred on site. The assessment and investigation has been undertaken in line with the Council’s approach to identification, assessment and remediation of contaminated land within the Borough, as required under Part 2A of the Environmental Protection Act 1990. The first stage comprised a desk study of geotechnical and geo-environmental factors pertaining to the site, including a review of available historical maps, site walkover and an examination of other available sources of readily available geo-environmental information to allow for the development of a conceptual site model (CSM). A Preliminary Risk Assessment (PRA) was to be undertaken as part of the desk study in accordance with Land Contamination Risk Management (LCRM). The objective of the risk assessment was to evaluate the site and plausible pollutant linkages as set out in, and supported by, statutory guidance with respect to the immediate liabilities under Part 2A of the Environmental Protection Act 1990, and risk posed to Controlled Waters under the Water Resources Act 1991. Following the PRA an intrusive investigation and detailed quantitative risk assessment was subsequently undertaken as part of this report. The objectives of the risk assessment were to evaluate the risks posed in relation to the land use of the site itself, to adjacent land uses and the wider environment, in the context of likely planning requirements, immediate liabilities under the Environmental Protection Act 1990 and risks posed to Controlled Waters under the Water Resources Act 1991 from the current status of the site. The data from the geotechnical assessment was to form the basis of an interpretation with respect to potential instability on the site. The works are being undertaken to inform the Client’s assessment of the site and allow for consideration of the stie under their Part 2A duties.

Part 2A of the Environmental Protection Act

Part 2A of the Environmental Protection Act (EPA) 1990 came into force in England in April 2000. This introduced a regulatory regime for the identification, assessment and remediation of land which falls within the statutory definition ‘contaminated land’. The primary regulators under Part 2A are local authorities. S78(2) of EPA 1990, as amended by the Radioactive Contaminated Land (Modification of Enactments) (England) Regulations 2006, defines contaminated land as follows. Any land/area which appears to the local authority in whose area it is situated to be in such a condition, by reason of substances in, or under the land, that: a) Significant harm is being caused or there is significant possibility of such harm being caused, or b) Pollution of controlled waters is being or likely to be caused. And in relation to harm so far as attributable to radioactivity, Any land which appears to the local authority in whose area it is situated to be in such a condition, by reason of substances in, or under the land that: a) harm is being caused, or b) there is significant possibility of such harm being caused.

Ground Investigation Report

Statutory guidance issued by Defra (April 2012) is an integral part of the regime as it provides guidance and details how specific elements of the regime are to be implemented. This guidance includes the supposition that land is uncontaminated unless or until evidence proves the contrary. In addition, the guidance also states that regulatory decisions should be based on what is reasonably likely and not on what is hypothetically possible. The overarching objectives of the regime are to provide a formal system for the identification, assessment and remediation of land where contamination is causing unacceptable risk of harm to human health or the environment. Contaminant linkages and the associated risk of harm are to be assessed in terms of current use and the circumstance of the land in accordance with the Government’s “suitable for use” approach. A cornerstone of the regime is the ‘polluter pays’ principle, whereby the cost of dealing with any contamination falls upon those (appropriate person(s)) who cause or knowingly permit the contaminating substance(s) to be present. Where such persons cannot be found, and with the exception of contamination solely relating to pollution of controlled waters, the current owner or occupier of the land would normally become responsible. Typically, remediation on a voluntary basis is promoted under the regime. However, where voluntary remediation is not forthcoming, and subject to various conditions, the regulators have a duty to secure appropriate remediation by serving a Remediation Notice on the appropriate person(s). At the point of reporting, agreement of investigation works on site was obtained from the Landowner on a voluntary basis with a view to mitigating the fires occurring on the site. 1.6

Part 2A Inspection Strategy

The Part 2A regime sets duties on local authorities to undertake periodic inspection of their areas for the purpose of identifying potentially contaminated land and determining whether this is a potential special site. The local authority is required to develop a strategic approach which is rational, ordered and efficient and which ensures that land which merits more detailed inspection due to potential contaminant linkages which could exist, is identified efficiently. Detailed inspection may comprise one or more of the following: 1) The collation and assessment of documentary evidence, or information from other sources. 2) A visit to the subject site for the purpose of visual inspection, which may include limited sampling. 3) Intrusive investigation of the land. The Contaminated Land Statutory Guidance states that where intrusive investigation is required, this should be undertaken “in accordance with appropriate good practice technical procedures for such investigations”. 1.7

Risk Assessment Framework

Land that has been polluted or contaminated will not necessarily fall within the above legal definition of contaminated land. The Local Authority is required to make any determination of a site as “contaminated land” in accordance with statutory guidance and following the well-established principles of risk assessment including the concept of a contaminant linkage (also often referred to as a pollutant linkage) where:

3 GE21483/GIRv2.0/DEC23

Arnold’s Field, Launders Lane, Rainham, RM13 9GJ London Borough of Havering Council

Ground Investigation Report

a) A “contaminant” is a substance which is in, on or under the land and which has the potential to cause significant harm to a relevant receptor, or to cause significant pollution of controlled waters. b) A “receptor” is something that could be adversely affected by a contaminant, for example a person, an organism, an ecosystem, property or controlled waters. The various types of receptors that are relevant under the Part 2A regime are set out in the statutory guidance. c) A “pathway” is a route by which a receptor is or might be affected by a contaminant (of a type specified in the regulations). Land cannot be determined as contaminated land unless all three elements of a pollutant linkage are present and the linkages are demonstrated to be significant. In some cases pollutant linkages can change, when new receptors are introduced following the change in land use, for example following development. The term “contaminant linkage” means the relationship between a contaminant, a pathway and a receptor. All three elements of a contaminant linkage must exist in relation to particular land before the land can be considered potentially to be contaminated land under Part 2A. Where the terms significant contaminant and significant contaminant linkage are used within this assessment, they are used in accordance with their definitions within the Statutory Guidance. In order to determine the land as contaminated land, the local authority must be able to demonstrate that one or more contaminant linkage exists in relation to the land and that at least one of the following situations arises: i. ii. iii. iv.

The contaminant linkage(s) result(s) in significant harm being caused to the receptor in the linkage; There is a significant possibility of significant harm being caused to that receptor; The contaminant linkage(s) result(s) in the pollution of controlled waters; or It is likely to result in such pollution.

The statutory guidance provides further detail and the conditions by which “significant harm” and “significant possibility of significant harm” are to be assessed. If at any stage of the assessment process the Local Authority considers on the basis of the information obtained from inspection activities that there is no longer a reasonable possibility that a significant contaminant linkage exists on the land, the authority should not carry out any further inspection in relation to that linkage. In such circumstances, the Local Authority should refer to Sections 5.2-5.4 of the statutory guidance. 1.8

Context for this Assessment

Under the Environmental Protection Act 1990 Part 2A the London Borough of Havering is required to determine whether land within its jurisdiction is contaminated. The London Borough of Havering commissioned Geo-Environmental to carry out a site specific assessment within a scope of work which included: • • •

Review of existing documentary information; Visual inspection of land within the inspection boundary (subject to any current restriction on access given the current land use); Establishing the significance of any pollutant linkages that can be identified through the review of desk based information and visual inspection;

Identify data gaps and uncertainties relating to the pollutant linkages identified on the basis of documentary review and visual assessment – the output of this was then utilised to design an appropriate preliminary intrusive investigation for the site. Undertaking of the intrusive investigation and subsequent risk assessment based on the intrusive investigation. Conditions

The desk study data obtained for the site is assumed to be factually correct and up to date at the point of their acquisition. No liability is taken for any omissions or inaccuracies in the data acquired and no attempt has been made to verify the data in this respect. It should also be noted that changes to the desk study data obtained as part of the production of this may occur at source following the production of this report,, Geo-Environmental accepts no liability where any changes in data pertaining to the site occurs and subsequently affects the assessment presented herein. The information collected from the desk study and site walkover has been used to provide an interpretation of the geotechnical and environmental conditions pertaining to the site. The recommendations and opinions expressed in this report are based on the data obtained and the results should be viewed in the context of the range of data sources consulted. Geo-Environmental takes no responsibility for conditions that have either not been revealed in the available records or that occur between or under points of any physical investigation. Whilst every effort has been made to interpret the conditions, such information is only indicative and liability cannot be accepted for its accuracy. In addition, the information obtained in relation to the site and presented herein, may not be exhaustive and further information relevant to the site may be available from other sources which has not been provided or obtained as part of this report. The data collected from the investigations have been used to provide an interpretation of the geotechnical and/or environmental conditions pertaining to the site. The recommendations and opinions expressed in this report are based on the data obtained. Geo-Environmental takes no responsibility for conditions that either have not been revealed in the available records, or that occur between or under points of physical investigation, or that result from updates to desk based data utilised subsequent to that presented herein and at the time of writing which may in turn alter the presented assessment. Whilst every effort has been made to interpret the conditions, such information is only indicative and liability cannot be accepted for its accuracy. It should be noted that in particular the concentrations and levels of mobile liquid and gaseous materials are likely to vary with time. The results obtained may therefore only be representative of the conditions at the time of sampling. The absence of asbestos within soil samples analysed does not guarantee the absence of asbestos within buildings, within or bonded to concrete, as discrete burials, or within the soils mass elsewhere within a site.

DESK STUDY

The findings of the Phase I desk study are presented in the following section. A copy of the information obtained as part of the desk study is presented in Appendix A. Comments made in the following sections regarding possible ground conditions on the site are based purely on the desk study assessment undertaken and associated site walkover. 2.1

Site Description

The site comprises an irregularly shaped parcel of land which extended to c.16.94Ha and was located at NGR 554116, 182008. The site is understood to comprise a former sand and gravel quarry that was subsequently registered as a landfill with the last waste recorded as being accepted in 1965. The site was licensed to accept inert, commercial, industrial, household and solid sludge waste. The details of the type of restoration works on the site post landfilling are unknown but is assumed that the site was restored with a thin cap of non-landfill materials, e.g. soil or stone. No measures to deal with possible ground gases are understood to have been installed as part of any restoration works. More recently unauthorised placement of waste materials has occurred on the site. A review of historical photographs indicates that some level of earthworks, materials movements and potential placing of materials occurred between 1999 and 2019. A Freedom of Information Request by Geo-Environmental to the Environment Agency detailed that between 30,000m3 and 50,000m3 of waste material was deposited on site between 2011 and July 2014. This material consisted of mixed household, commercial and industrial material, suspected from a waste transfer station. It is understood that the site has the tendency to combust periodically, causing smoke and odour issues associated with fires on site. The nature of the ground on the site is uneven, with significant and sometimes sudden variations in elevation across the site. Areas of the site were noted to be significantly raised in relation to the adjacent road (Launders Lane), with the highest elevation being located in the centre portion of the site sloping down to towards the stream boarding the site and adjacent roads. The southern portion of the site was noted be at generally a lower elevation than the central and norther area of the site. Traversing the site with access being created through bunds and around bunds on site and down slopes was noted to be slow and restricted areas where movement and access around site could be safely undertaken (both when undertaking a site walkover and with plant). The site is noted to be quite densely overgrown (weeds, brambles and low levels bushes) and uneven underfoot in areas with significant obstructions, including but not limited to construction rubble, plastic, wood, metal domestic waste (including plastic and black bin bags), appliances (including toasters and the like), fabric and material tentatively identified as Asbestos Containing Materials (ACMs) and the potential for voids as a results of poor compaction of historical/recent fires on the site, actively smouldering areas or fires, levelling and revegetation of local areas in order to gain access with the dynamic sampling rig was required as vegetation could be dense and some ruts/hillocks on site were steep and or large in nature. The southern portion of the site was noted to be more open and less overgrown with vegetation than the central and northern areas of the site. 7 GE21483/GIRv2.0/DEC23

Ground Investigation Report

The site is bordered to the northwest and northeast by the Common Watercourse to the southwest by the A1306, to the southeast by Launders Lane with attenuation basins and a golf course beyond, and with a stream running along the western site boundary. The topography of the site is such that the site slopes steeply down towards the stream along the boundaries. The site boundaries were also noted to be very heavily vegetated. A small area of hardstanding was located on the south-eastern boundary of the site directly off Launders Lane, though double metal gates. A metal container was located in the north of the hardstanding. At the point of the site walkover on the 8th August 2023 it was understood that concrete blocks has previously be placed in front of the gates, however these had been moved to allow access. A further smaller tarmacked access was present towards the southern area of the site off Launders Lane, which at the point of the walkover and site investigation works had concrete blocks and fly tipped materials at the entrance with only pedestrian access possible. It is understood that a number of fires have occurred on the site historically and more recently believed at this stage to be associated with the waste mass in the upper layers (historically unauthorised deposited materials) on site. Smouldering trenches were also noted within the central portion of the site during the walkover. It is understood that further fires have also occurred more recently on the southern portion of the site (end of August/beginning of September). Google maps shows historical evidence of areas of burnt ground located in the southern area of the site between the A1306 New Road and Launders Lane. During site investigation works a pile of surface tipped material was smouldering in the southern area of the site. It is understood from Havering Council’s Environmental Health Officer (EHO) that during fire brigade attendance on site the fire crews have refrained from walking or taking equipment directly onto the site due to concerns regarding stability of the site, in particular in relation to areas where fires may have been occurring underground and appear to comprise burning waste materials. It is understood that fires have been dealt with via spraying water onto the site/fire from height along site boundaries. The surrounding land uses were noted to comprise a stream bordering the north and western boundary of the site, Launders Lane to the east, and the A1306 located to the south of the site. The wider area comprised a mix of commercial land uses (comprising mineral extraction and landfilling operations, a golf course to the east of Launders Lane, a cricket ground to the northwest and further agricultural land and a park/area of public open space. The closest residential development was Rainham further to the west and northwest of the site. A selection of the photographs from the site walkover and intrusive works are included as Appendix B. 2.2

Geology

British Geological Survey (BGS) geological mapping indicated the site to be underlain by a succession of natural geology comprising Alluvium, Head Deposits, Taplow Gravel Member and London Clay Formation. In addition, the site is mapped as infilled ground and is understood to have been subject to extraction of natural strata, e.g. sand and gravel, followed by landfilling such that a variable thickness of Made Ground is also anticipated to be present. BS5930:2015 defines Made Ground as anthropogenic ground in which the material has been placed without engineering control and/or manufactured by man in some way, such as through crushing or washing, or arising from an industrial process. Great variations in material type, thickness and degree of compaction invariably occur and there can be deleterious or harmful matter, as well as potentially methanogenic organic material. In addition, on sites which have undergone several phases of historic development it is not uncommon for asbestos to be present at surface and within Made Ground and/or disturbed soils. Alluvium is the most recent river or estuarine deposit and generally comprises silty clays usually with an appreciable organic content. Lenses of sand and gravel are also commonly found, as are pockets of peat. 8 GE21483/GIRv2.0/DEC23

Arnold’s Field, Launders Lane, Rainham, RM13 9GJ London Borough of Havering Council

Ground Investigation Report

Head Deposits are drifts produced by solifluction, the downslope movement of debris outwash during the periglacial period, and characteristically comprise poorly sorted clay, sand, gravel and rock of local derivation. The Taplow Gravel Member mainly comprises sand and gravel with localised lenses of silt, clay or peat. The deposits are generally found at an elevation close to or higher than that of the existing rivers. The Taplow Gravel Member forms part of the Maidenhead Formation of the Thames River Terrace Deposits. London Clay Formation in the study area is characterised by stiff grey fissured clay, weathering to brown near surface. Concretions of argillaceous limestone in nodular form (Claystones) occur throughout the formation. Crystals of gypsum (Selenite) are often found within the weathered part of the London Clay, and precautions against sulphate attack to concrete are sometimes required. The lowest part of the formation is a sandy bed with black rounded gravel and occasional layers of sandstone and is known as the Basement Beds. In the north London area the upper part of the London Clay has been disturbed by glacial action and may contain pockets of sand and gravel. 11No. BGS borehole records were identified within the site by the Groundsure dataset, records of which are noted to be from the early 1960s and 1970s. The borehole logs report Topsoil and/or Made Ground across the site with Made Ground was described primarily as bricks and rubble. Sand and gravel were reported to underlie the Topsoil and/or Made Ground between 0.30m-0.90m bgl to 4.50m-5.50m bgl, which was then reported to be underlain by firm to stiff clays of the London Clay Formation between 20.00m and 56.20m bgl. One borehole reported Oldhaven Beds and Woolwich Beds (now referred to as the Lambeth Group) to 75.00m bgl underlain by Thanet Sand to 77.11m bgl where the hole was terminated. 2.3

Hydrogeology

With reference to Groundsure data, the underlying superficial strata were classified as a Secondary ‘A’ aquifer (Taplow Gravel Member) and Secondary Undifferentiated Strata (Alluvium and Head Deposits) and the bedrock strata was classified as Unproductive Strata (London Clay). Secondary ‘A’ aquifers are defined as, permeable layers capable of supporting water supplies at a local rather than strategic scale, and in some cases forming an important source of base flow to rivers. These are generally aquifers formerly classified as minor aquifers. Secondary Undifferentiated aquifer is the assigned in cases where it has not been possible to attribute either category A or B to a rock type. In most cases, this means that the layer in question has previously been designated as both minor and non-aquifer in different locations due to the variable characteristics of the rock type. Unproductive Strata are rock layers or drift deposits with low permeability that have negligible significance for water supply or river base flow. According to information provided from the Environment Agency the site was indicated to be outside of any Source Protection Zone with regard to the protection of groundwater for potable supply. The environmental dataset did not identify any licenced discharges to controlled water (land/soakaway) within 500m of the site.

The site was identified as being located within an area with moderate risk of groundwater flooding to occur this is the highest risk within 50m of the site. It is worth noting the majority of the site is negligible risk with the moderate risk areas associated with the stream along the northern and western site boundaries (referred to as the ‘Common Watercourse’, historically identified as the ‘Common Sewer’). 2.4

Hydrology

With reference to the Groundsure dataset, while no surface water features were identified on the subject site itself, the closest surface water feature was located running roughly north-south along the western boundary of the site and comprised an ‘Inland River not influenced by normal tidal action’. Referred to as the Common Watercourse. While the Groundsure data indicated the majority of the site was located in a Flood Zone 1, the boundaries of the site to the northwest and northeast of the subject site were shown to be located within a high risk area for river and coastal flooding (Flood Zone 2 and 3). However, these areas are noted to be located in an area benefiting from the presence of flood defences. Four discharge consents to controlled waters were identified within a radius of 500m of the site boundary: •

It is considered unlikely that the discharge consents or recorded pollution incidents will have ongoing impacts to the site due to the dates of incidents, types of materials discharged, pollutants released and the designated water impact categories. 2.5

Radon

The Groundsure report states that the site lies in an area where <1% of homes are above the Action Level as defined by Public Health England and the BGS. In addition, the BGS assessment states that no radon protective measures are required in the construction of new houses or extensions on the site.

The Groundsure data utilises the recently updated Radon dataset, effective as of 1st December 2022, and is based on a 50m grid square. 2.6

Environmental Data

Searches of other various environmental databases were made as part of the desk study, including air pollution control sites, Part IIA contaminated land, Integrated Pollution Control (IPC) and Integrated Pollution Prevention and Control (IPPC) sites, registered radioactive substances, COMAH sites, explosives sites, Notification of Installations Handling Hazardous Substances (NIHHS) sites, planning permissions for sites involving hazardous substances and fuel station registers. Additional detail is referenced in Appendix A. The Groundsure dataset did not identify any of the above-mentioned sites within 500m of the site boundary. However, the following industrial land uses/trade directory entries were identified in proximity to the site: • 2.7

Data obtained as part of the desk study provides details on the estimated soil chemistry for the natural soils in the vicinity of the site. The estimated soil quality on the subject site is presented Table 2.1. Contaminant Estimated Concentration Arsenic 15 – 25 mg/kg Cadmium 1.8 mg/kg Chromium 60 – 180 mg/kg Lead 100mg/kg Nickel 15 – 45 mg/kg Table 2.1 Estimated soil chemical concentrations of natural soils on site However, it should be noted that this site has been subject to quarrying, landfilling and unathorised deposit of waste over its history and as such it is considered that presence of natural soils across the majority of the site in unlikely. As such, these values are not necessarily representative of the site’s soil chemistry and do not take account of the potential presence or condition of any Made Ground and do not account for a site’s historic or current use. Furthermore, some screening criteria are dependent on pH and soil organic matter content. Therefore, concentrations of specific determinands and the utilised S4UL/C4SL cannot be determined without site specific investigation and analysis. 2.8

Sensitive Land Uses

A search was made of environmentally sensitive areas including local and national nature reserves, areas of outstanding natural beauty (AONBs), Ramsar sites, sites of special scientific interest (SSSIs), conservation areas, special protection areas and biosphere reserves. No environmentally sensitive areas were identified within 500m of the site boundary, with the exception of the site being located within Havering Green Belt. According to the Groundsure data set, the site lies within a surface water Nitrate Vulnerable Zone (NVZ), Southall 13 GE21483/GIRv2.0/DEC23

Table 2.3 Summary of landfill and waste management facilities within 500m of the site

Subsequent to the landfill activity on the site as referred to in Table 2.3 above it understood that the site has been subject to unauthorised deposit of waste activates on site. A review of historical photos from Google Earth indicated some level of earthworks, materials movements and potential placing of materials occurred may have occurred between 1999 and 2019 (Copies of relevant photos are presented in Appendix A, with the desk study information). Information raised by a member of the public at a public meeting of residents of Havering Borough Council in Rainham on the 1st September 2023, indicated there was information and a concern with respect to the potential for radioactive waste from the former Olympic development site in London to have been deposited at Arnolds Field as part of the unauthorised deposit of waste. To date no actual evidence of this activity has been made 16 GE21483/GIRv2.0/DEC23

Environment Agency Response (Freedom of Information Request)

A freedom of information request was made to the Environment Agency on the 15th June 2023 in relation to information pertaining to the subject site. A copy of the Environment Agency response is presented in Appendix A. The Environment Agency have advised that due to the timeline for the historical landfilling works on the site the records in relation to the subject site itself are no longer held by the Environment Agency. In addition, it is understood that the Environment Agency have historically commissioned an investigation by Jacobs pertaining the site itself in relation to the subsequent unauthorised deposits of waste on the site. However, due to the time lapse since this report was produced this is also no longer held within the Environment Agency’s records. In summary the Environment Agency freedom of information request in relation to the site response stated ‘Having reviewed our case file, we do not hold any permits, and/or Compliance Assessment Reports. We have no records of any surveys and/or sampling results for the site within the historic casefile. We are aware from our investigation at the site, that between 2011 and July 2014 there was extensive deposits of non-hazardous waste at site, approximately between 30 to 50,000 cubic metres. Waste consisted of mixed household, commercial and industrial material, suspected from a waste transfer station. We took prosecutions against three offenders, who were convicted for the deposits.’ 2.12

Table 2.4 Summary of historic map extracts

From 1862 historic mapping showed the site to have been open fields with hedgerow boundaries. A marsh area was mapped along the west boundary between 1895 to 1921. The 1967 mapping showed a sand and gravel pit extended across almost the entire site; this was shown until the 1973-1974 mapping. It is understood that the site was quarried for the sand and gravel deposits of the Taplow Gravel. This pit (sand and gravel extraction) ceased to be mapped and no further changes were mapped for the site, although landfill records subsequently indicate that the site was infilled with inert and household waste. While not mapped on the historical maps reviewed for the site, the site is understood to have been subject to the further deposition of waste (without formal permitting or regulatory authorisation/approval) following any formal reinstatement works of the original permitted landfill. A review of aerial photographs from Google Earth indicates that earthworks and deposits of further waste materials occurred on site between 1999 and 2019 (copies of

The surrounding area remained fairly open for the duration of the mapping. There was development shown c.500m west, north and south of the site. The land to the east of the site was also shown to comprise an area where large sand and gravel pits were noted over the mapping period as well as large water bodies (assumed to be settlement ponds) associated with these areas, some of which were then mapped as subsequently having been infilled. 2.13

Asbestos

During the initial site walkover undertaken on the 8th August 2023 no clear evidence of asbestos containing materials was observed. In line with current best practice, asbestos and ACM should be assumed to be present until proven otherwise, this includes the consideration of the potential for asbestos to be present within the shallow soils on the site as well as beneath areas of hardstanding. It should be noted that the site was noted to be overgrown at the point of the site walkover in August 2023 which may have masked the presence of readily visible asbestos/Asbestos Containing Materials (ACM). A subsequent site walkover of the site was undertaken in September 2023, during which time some site clearance and tracking of an excavator was undertaken to create access routes around the site, did however identify the presence of ACMs at the surface of the site. It should however be noted that the absence of asbestos recorded across parts of the site as part of the site walkover/s is not a guarantee of the absence of asbestos elsewhere on a site. 2.14

Unexploded Ordnance (UXO) Risk

A review of the Zetica UXO Risk Mapping was undertaken, which indicated that the site was located in an area considered to be high risk with respect to UXO. A preliminary desk based risk assessment was undertaken for the site by Zetica. This highlighted that during WWII the site was located in the Urban District (UD) of Hornchurch, which officially recorded 1,091No. High Explosive (HE) bombs with a bombing density of 55.1 bombs per 405 hectares (ha). Readily available records were found to indicate that several HE bombs fell in close proximity to the site. Further liaison was undertaken with Zetica in relation to the historical use of the site as a former sand and gravel quarry which was then subject to infilling and unregulated waste disposal. Zetica confirmed that where works were confined to within the depth and footprint of the post WWII intrusive works (i.e. former quarried area) of the site, the likelihood of encountering UXO on the site was considered to be low. Third party information from liaison with the Council and GEMCO (the Landowner’s Consultants for the site) indicated that the previous site walkovers on site had indicated that there were other potential explosion hazards identified within the unregulated waste at the site including Liquid Petroleum Gas (LPG) cylinders. In addition, the presence of ground gases were identified as a potential risk driver in relation to the site. It was concluded that the risk with respect to UXO had been considered, however there remained the potential for further explosion risks at the site relating to items within the waste.

Previous Ground Investigations

Geo-Environmental have been made aware of the following 3rd party reports that have been undertaken in relation to the site: • •

Phase 1 Geo-Environmental Assessment for Land at Arnolds Field, Launders Lane, Rainham, Essex RM13 9FL, by GEMCO (Green Earth Management Co. Ltd), on behalf of SMC Services (Essex) Limited, reference 1774 R01: Issue 2, dated December 2020. Outline Remediation Strategy for Land at Arnolds Field, Launders Lane, Rainham, Essex RM13 9FL, by GEMCO (Green Earth Management Co. Ltd), on behalf of SMC Services (Essex) Limited, reference 1774 R02: Issue 1, dated October 2022.

Geo-Environmental have also been informed by Havering Borough Council that previous investigation works have been undertaken on the site commissioned by the Environment Agency in relation to the unregulated deposit of waste materials on the site and reported by Jacobs. However, whilst a copy of this report has been requested it is understood that a full copy is no longer held on file by the Environment Agency and to date Geo-Environmental have been unable to obtain a copy. Reference is made in GEMCO’s Phase 1 Assessment Report to a technical note undertaken by Jacobs dated March 2012. The summary provided in the GEMCO report indicates that the materials encountered on site comprised ‘brown sandy gravelly clay or sandy clayey gravel over recently deposited landfill waste, or further made ground of black clayey sandy gravel with ash, peat/decayed vegetation, brick and concrete. The recent landfill comprised domestic and commercial waste including documents, wood, paper, glass, plastic, mattresses, furniture/equipment, cables, netting, fabric and occasional empty medical waste packaging.’ The summary also reports that Jacobs concluded that there was ‘little evidence of decomposition suggesting recent deposition.’ ‘With waste reported to typically noted to be warm/emitting vapour suggesting decomposition was occurring and landfill gasses may be being generated. The full depth of the recent waste material was not proven up to a maximum achieved depth of 4m below ground level.’ A summary of geochemical testing undertaken ‘(where sufficient soil material was available to enable sample collection) identified concentrations of Lead of 1600mg/kg, Benzo(a)pyrene at 2.1mg/kg and Waste Acceptance Criteria Testing which indicated that sulphate concentrations would be above the threshold for inert waste.’ 2.16

Potential Contamination

The site’s previous uses comprised agricultural land, primarily open fields, followed by sand and gravel extraction and more recently as a landfill and area of land subsequently subject to unauthorised deposition of waste. Elevated concentrations of contaminants of concern could potentially be present within Made Ground/waste materials and shallow natural soils underlying the site given the site’s uses. In addition, the presence of surface and/or subterranean fires that have occurred on site are suggestive of organic rich and readily combustible wastes within the landfill mass. The fires noted to have occurred on site are not understood to be limited to a single area of the site, with fires having occurred in the northern and southern area of the site, indicating there is a sporadic element to the fires. The presence of fires occurring on site indicates the potential for organic rich wastes to be present, or the potential for an uncompacted waste with a high plastic content with sufficient oxygen flow throughout and potential for variation of materials laterally and with depth on the site or associated with methane generation within the on-site wastes.

21 GE21483/GIRv2.0/DEC23

Arnold’s Field, Launders Lane, Rainham, RM13 9GJ London Borough of Havering Council

Ground Investigation Report

The presence of contamination is considered likely based on the information reviewed and our understanding of the site history. It would be prudent to assume that along with the presence of commonly occurring brownfield contaminants those associated with household, commercial, inert, industrial and liquid sludge wastes may be present based on the historic landfill records for the site. Potential contaminants could include, heavy metals, organic pollutants such as poly-aromatic hydrocarbons (PAH), SVOCs and VOCs, inorganic compounds, organic/combustible wastes, plastics and plastics additives, PFAS and PFOA substances (within the buried wastes and from any firefighting foams), asbestos, pesticides, and fertilisers. Further information on the site and landfilling activities was requested via a freedom of information request to the Environment Agency. However, the response stated that due to the age of the site the records were no longer available. Six historic and five active or recent landfill sites are located within 500m of the site, located to the north, south and west of the site (and including the on-site landfill). There is potential for contaminants associated with these off-site landfill sites to migrate, e.g. through more permeable strata and borne in groundwater and/or surface water and impact the subject site. Potential contaminants associated with these landfills include heavy metals, organic pollutants such as poly-aromatic hydrocarbons (PAH), petroleum hydrocarbons/ oils, inorganic compounds, SVOC and VOCs, PCBs. Ground gas is considered below. It also remains possible that the surrounding land uses may have resulted in the deposition of airborne contaminants on the surface and shallow soils on site including heavy metals, organic pollutants such as polyromantic hydrocarbons (PAH), petroleum hydrocarbons/oils, inorganic compounds. 2.17

Ground Gas and Vapour Summary

The desk study has identified the potential for ground gases and vapours associated with the former on-site landfill site and unauthorised deposited waste materials, together with a risk from organic rich waste that may be present on site and the potential for methane generation within the on-site waste materials. The onsite landfill is recorded as having accepted domestic waste and if/where present this represents a high potential source of methane. Migration of gas and vapours to the site from former landfill sites to the north, south and west of the site is also potentially possible. These landfill sites represent a potential source of ground gas due to the types of wastes that were permitted and deposited. The anticipated natural geology underlying the site comprises a succession of Alluvium, Head Deposits and Taplow Gravel overlying the London Clay Formation. The underlying London Clay bedrock geology is primarily formed of impermeable clay layers and as such is unlikely to represent a plausible migration pathway for ground gases. It is unknown at this stage if the historical pit was formally lined or not. Given the age of the site and underlying geology comprising London Clay it is possible that a formal lining was not installed. However, the superficial deposits may contain permeable layers that could represent a plausible lateral migration pathway. Notwithstanding this, it is anticipated from review of the site’s history, that much of the sand and gravel within the site was extracted and replaced with overburden and landfill wastes. The permeable strata are still likely to remain present around the periphery of the site as some form of gravel pit benching, or battered sides required to maintain a stable site boundary. It is therefore possible that gas generated from off-site and on-site landfills could migrate and mix. Given the known history of the site, it is considered that there is potential for bulk gases such as methane, carbon dioxide and oxygen to be present together with trace gases such as hydrogen sulphide, carbon monoxide, VOCs and the like associated primarily with the historical landfill materials at depth on the site. Subterranean fires and the introduction of water into the landfill body are likely to cause variation in the composition of gases and vapours within the landfill waste mass over time. In addition, flow conditions are also likely to vary.

Arnold’s Field, Launders Lane, Rainham, RM13 9GJ London Borough of Havering Council

Ground Investigation Report

Ground gas monitoring is recommended to assess the presence, composition and flow conditions of bulk and trace gases within the site. It is recommended that ‘spot’ monitoring is undertaken in order to appropriately assess the risks from ground gases as an initial stage of assessment. Further monitoring in due course to comprise a period of continuous gas monitoring on the site may subsequently be required.

PRELIMINARY ASSESSMENT

Based on the findings of the desk study, the following sections summarise the anticipated geotechnical and environmental factors likely to impact the site. 3.1

Geotechnical Risk Assessment

3.1.1

Potential Geotechnical Issues

The following factors that might impact the geotechnical condition of the site were identified as part of the desk study: • • • • • • • •

The possible presence of Made Ground/Infilled Ground (e.g. varying depth and/or composition) with varying states of compaction which may affect the stability of areas of the site, particularly in areas where fires are known to have occurred. The presence of laterally and vertically variable strata due to the variability in deposited materials on site which may affect the stability of areas of the site, particularly in area where fires are known to have occurred. The suitability of shallow soils as a bearing stratum given potential variation in compaction and waste types across the site. Consideration of the volume change potential of any cohesive soils. The possible presence of aggressive ground conditions (sulphates). The possible presence of shallow leachate and/or groundwater beneath the site and impact this might and foundation excavations and stability on the site, e.g. collapse of excavations or instability during fires. The presence of any vegetation on the site, which may have an effect on stability of soils and variation in volume change of soils if/where shrinkable soils are present. The potential impact from infiltration of rainwater into the ground.

Preliminary Environmental Conceptual Site Model & Risk Assessment

3.2.1

Methodology

A Preliminary Risk Assessment (PRA) and Conceptual Site Model (CSM) has been prepared in accordance with Land Contamination Risk Management (LCRM) based on information obtained as part of the desk study. Possible risks associated with potential sources of contamination and sensitive receptors identified have been assessed following a source-pathway-receptor (SPR) approach in accordance with current UK protocols. The Conceptual Site Model for the proposed end use (Residential with plant uptake) is presented in Figure 2. A risk may only exist where a plausible SPR linkage is present, and where the quantity or concentration of a contaminant is sufficient so as to cause harm. Under the statutory definition, "Contamination" may only strictly exist where contaminants pose a risk of harm to a receptor. Risk may be defined as a function of the likelihood and severity of any adverse effects arising from contamination. The risk classification has been assessed in accordance with CIRIA C552 (Rudland et al., 2001). A summary of how the risks is derived and their definitions are presented in Tables 3.1 & 3.2 below.

High risk

Realisation of the risk is likely to present a substantial liability.

Urgent investigation (if not already undertaken) is required and remediation works may be necessary in the short term and are likely over the longer term. It is possible that harm could arise to a designated receptor from an identified hazard. Moderate risk However, it is either relatively unlikely that any such harm would be severe, or if any harm were to occur it is more likely that the harm would be relatively mild. It is possible that harm could arise to a designated receptor from an identified hazard. Moderate to low risk However, it is unlikely that any such harm would be severe, or if any harm were to occur it is probable that the harm would be relatively mild. It is possible that harm could arise to a designated receptor from an identified hazard, Low risk but it is likely that this harm, if realised, would at worst normally be mild. There is low possibility that harm could arise to a receptor. In the event of such harm Very low risk being realised it is not likely to be severe. Table 3.2 Risk rating definitions 3.2.2

Ground Investigation Report Source Off site land uses (quarries, landfills, cemetery and agricultural use)

Description Six historic and five active or recent landfill sites have been identified to the north, south and west of the site. As such, there is the potential that these land uses may have resulted in a potential impact to soils and groundwater beneath the site.

Contaminants Possible elevated concentrations of metals, metalloids, possible elevated organic pollutants such as TPH and PAH compounds, sulphate and asbestos, cyanide, ammonia, SVOC and VOCs, PCBs. [gas considered separately]

*A conversation between Geo-Environmental and the fire bridge recently indicated that to date primarily water has been utilised as opposed to foams.

Table 3.3 Possible sources of contamination 3.2.3

Summary of Plausible Pathways

The plausible pathways are summarised in Table 3.4. These pathways are based on the closest possible land use given the current vacant use of the site, which comprise a privately owned site which is not actively open to the public but that is not fully secured/fenced of such that unauthorised access is feasible. ‘Public open space, park’ scenario (albeit without permitted public access due to the site comprising private unsecure land) is considered to be the closest scenario to the current land use. Pathway

Description

Direct Contact

Ingestion of soil particles, inhalation of soil derived dust (including tracked back dust and including asbestos fibres), dermal contact.

Inhalation

Vertical & Migration

Lateral

Shallow Groundwater Chemical Attack Flooding

Inhalation of soil dust (outside). Inhalation of ground gas/vapours (outside). Contaminant movement both vertically through leaching/gravity and horizontally along preferential pathways, e.g. services trenches, more permeable strata or with groundwater, Infiltration to groundwater through the site as a result of precipitation, runoff to surface water. Migration of gases within the landfill body (lateral and vertical migration, migration through ad hoc void spaces and the like) such that the ‘plume’ of gas is detached from the originating source. Shallow groundwater or perched water may be present within the Made Ground or underlying superficial strata which could result in the vertical and lateral migration of contaminants. The superficial deposits are recorded as a Secondary ‘A’ Aquifer and Secondary Undifferentiated. Superficial strata are likely to be in hydraulic continuity with surface watercourses. Attack of buried plastics and concrete by aggressive ground conditions. The majority of the site is identified to be located in a Flood Zone 1, with high risk areas for river and coastal flooding in relation to the northern and western site boundaries. The site was also indicated to be located in an area at moderate risk from for the potential for groundwater flooding of property situated below ground level, however no properties are currently located or permitted in relation to the site.

Comments The current land use comprises private open land, but which is noted to be unsecure across areas of the site, such that the public access could feasibly occur. Vegetation is present on the subject site and comprises rough low level vegetation.

Aggressive ground conditions and depths of Made Ground may be present beneath the site.

Adjacent land use to the east is primarily a golf course and quarries, landfilling, commercial land uses and open space, with residential and commercial land uses further out from the site. Risk to adjacent land users associated with potential for airborne contaminants and smoke at times when fires are present on site and potential for asbestos fibre release where soils are disturbed/moved around site. The site overlies a Secondary ‘A’ Aquifer and Unproductive Strata and is outside of any SPZ. However, this is still considered to represent controlled water located beneath the site which could be subject to contamination from landfill leachate or from fire-fighting runoff. Surface water was identified along the boundary of the site comprising the ‘Common Watercourse’ running along the western and northern site boundary. Due to the sloping nature of the site to the west and north and overgrown nature of the watercourse, a visual assessment of any leachate impacts was not possible due to site access and the overgrown nature of the site.. No ecologically sensitive areas have been identified within 500m of the site. Ecological receptors have not been considered further.

Current owners/people accessing the site (with or without permission due to unsecure access) may come into direct contact with soils given the current status of the site, with the potential for these soils and waste mass to be exposed at the surface.

It should also be noted that the site is located in an area where numerous historical landfills are present. As such, the general background quality of any surface water should also be considered in the context of the wider areas and site uses. Reduced infiltration and potential mobilisation of surface water runoff from the site could be mitigated by reducing the infiltration through/across the waste mass materials on the site with the installation of a formal cap on site with surface water drainage, thereby reducing the potential for leaching of any contaminants.

No buildings are located on the site. The nature of the natural geology underlying the site is expected to be primarily impermeable where London Clay is present and with the sands and gravels having been quarried from the site historically. However, there is the potential for ground gases to migrate through the waste mass material on site and to vent to the atmosphere given the undeveloped nature of the site. Alternatively, where migration of gases is low, pockets of ground gas could build up beneath the site. Where a significant concentration of methane or volatiles builds up in this way this could represent potential explosion or fire source on the site. Given the elevated nature of the site in relation to the surrounding land it is considered unlikely that significant gas migration onto the site would occur from the neighbouring landfill sites.

Table 3.6 Plausible pollutant linkages & qualitative risk assessment

Risk & Justification Low There is the potential that contaminants associated with other landfilling activities the area may have resulted in contamination to groundwater in the vicinity of the site, however given the underlying natural geology at depth this is considered a low likelihood to result in a determinantal impact beneath the subject site. Moderate/Low It should also be noted that the site is located in an area where numerous historical landfills are present. As such, the general background quality of any surface water should also be considered in the context of the wider areas and site uses.

It should be noted that the risk from smoke associated with fires on the site represents a health and safety concern associated with the smoke itself and any potential for particulates to be present/migrating as opposed to a contaminated land issue.

Preliminary Risk Assessment Summary

The Preliminary Risk Assessment (PRA) and Conceptual Site Model (CSM) developed from the information gathered as part of the desk study process have identified plausible significant potential pollutant linkages that exist in relation to the current status of the site. The potential pollutant linkages established within this desk study have been considered in the context of the proposed current status of the site, the potential for increased or variation in risk associated with fires on site, and are considered to require investigation and further assessment to support further characterisation, calibration of the CSM and where/if necessary, determine a remedial strategy to reduce, remove or otherwise control any risk within the site to key receptors. It should, however, be noted that the PRA acknowledges that there were numerous uncertainties associated with the existing data. The primary uncertainty being due to the lack of site specific information on the condition of the soils and waste beneath the site. In order to progress the risk assessment and Part IIA assessment of the site, to provide further characterisation of the site, and refinement of the PRA and CSM, it was concluded within the preliminary risk assessment that intrusive investigation and analysis would be required to clarify the presence and magnitude of any contamination and significant risk. As such, the following preliminary geochemical investigation was proposed to be out on the site to include analysis of soil and groundwater (if encountered) samples for the range of potential contaminants identified within the desk study as well as a period of ground gas and groundwater monitoring. It should be noted that the assessment will be undertaken to take account of risk and potential liabilities required to be considered under Part IIA which requires one or more of the following: 1) The collation and assessment of documentary evidence, or information from other sources. 2) A visit to the subject site for the purpose of visual inspection, which may include limited sampling. 3) Intrusive investigation of the land. The works are required to determine if there is the potential for the Part IIA regime to have been triggered in relation to source-pathway-receptor linkages identified on the site such that a significant potential of significant harm (SPOSH) is deemed to have been identified that would potentially require further assessment and determination of required works to mitigate the identified risks. Assessment of risks will be undertaken in relation to key receptors such as human health, controlled waters, built environment, soft landscaping and the like in liaison with the Local Authority and the Environment Agency depending on the risk identified. Any requirement for risk mitigation measures and remediation works on the site cannot be determined until such time as an intrusive investigation and associated testing has been completed. The aim of any remediation works would be to reduce the risk of significant potential of significant harm in relation to the site, based on its current status and land use. Any consideration of the potential for future development works on the site fall outside the scope of works proposed. In addition, it is anticipated that if gross soil contamination is encountered, or pockets of asbestos impacted soils are present, these materials could be classified as Hazardous Waste if off-site removal was required.

Scope of Works

The following scope of works for the intrusive investigation was agreed with the Client, and reviewed by the Landowner of the site and undertaken in September 2023: • • • • • • • • • • • 4.2

Attendance of a specialist surveyor to survey the investigation positions to capture the co-ordinates and levels of exploratory holes using GPS surveying; Attendance of a Geo-Environmental Engineer to set out and supervise the intrusive investigations, undertake sampling, in-situ testing and logging of recovered soils from exploratory holes; Provision of Photo Ionisation Detector (PID) to assess the soils for VOCs and to support the targeting of the laboratory analysis of samples recovered. Provision of a Tracerco T401 Radiation Contamination Monitor to assess soils recovered from the investigation positions. 13No. machine excavated trial pits to depths of between 3.00m and 4.50m bgl (TP101 to TP113). Initially 15No. trial pits were proposed however, slow tracking and creation of safe access around the site was such that this was limited to 13No. locations being achievable while on site; 18No. dynamic sampler boreholes to depths of up to 5.00m bgl (WS101 to WS106, WS106a, WS107, WS107a—c, WS108, WS108a-b, WS109, WS109a-b and WS110). Several locations refused at shallow depth such that additional positions were drilled in close proximity with a view to trying to achieve proposed depths. Installation of 10No. boreholes (WS101, WS102, WS103, WS104, WS105, WS106a, WS107c, WS108b, WS109b & WS110) with gas and groundwater monitoring standpipes; Return spot gas and groundwater monitoring of standpipes on six occasions. Water/leachate sampling on a single occasion during the first return monitoring visit. Geochemical laboratory testing to support a contamination assessment and preliminary waste assessment for the site; Provision of a Ground Investigation Report. Investigation Strategy

The positioning of exploratory holes was determined on site to provide general coverage of the site in relation to historical landfilling and subsequent unlicensed deposits of waste materials on the site and to target specific areas based on the site walkover. It should be noted that the feasibility and access of investigation positions was subject to the creation of tracking routes round the site where topography and changes in levels were safe to allow. In some central areas of the site steep gradient changes were such that they prevented direct tracking around the site which therefore limited the areas where investigation works could be safely undertaken within the agreed timeframe for the investigation works on site. A plan showing tracking routes created and undertaken around the site is presented in Figure 3. Table 4.1 sets out the investigation strategy adopted. Area of Concern General ground conditions Potential contamination of near surface soils (Top 3-4m bgl) Potential contamination of near surface soils (Top 5m bgl)

Soil and water samples were collected and placed into amber jars and cool boxes on site for transit to the office, where they were stored under chilled conditions (<4oC) prior to final transportation in cool boxes to the laboratory by their in-house courier. Both the geotechnical and contamination testing were undertaken by UKAS accredited laboratories (where appropriate). Contamination testing of soil samples was also undertaken in accordance with accredited MCERTS protocols. Samples were stored in temperature-controlled conditions from sampling until receipt at the laboratory from which time sample preparation and storage was determined by testing requirements and in line with laboratory’s protocols.

ENCOUNTERED CONDITIONS

A factual record of the conditions encountered during the physical investigation of the site is presented in the following sections. For further details of the ground conditions, reference should be made to the site photographs presented in Appendix B. The exploratory hole logs and cross sections are presented in Appendix C, the geochemical testing results (soil and water/leachate) in Appendix D and E and the return spot gas and water monitoring results in Appendix F. The HazWasteOnline Assessment is in Appendix G. The physical ground investigation works were undertaken between 18th and 22nd September. Return gas and groundwater monitoring has been undertaken on six occasions (3rd, 13th and 27th October, 6th, 20th November and 4th and 6th December 2023. The final monitoring visit was split into two due to unforeseen issues with the technician’s vehicle). Water/leachate sampling of monitoring installations where sufficient water was recorded within the standpipe was undertaken as part of the 3rd October 2023 sampling visit, with samples submitted to the laboratory for analysis. A further round of water/leachate sampling was undertaken on the 6th November 2023. At the time of writing, further liaison is ongoing with Havering Council to determine if sufficient budget is present to allow analysis of this second round of samples collected. Unless stated otherwise, all depths are reported as metres below ground level (m bgl). 5.1

For more detailed descriptions at specific locations, reference should be made to the exploratory hole logs presented in Appendix C. No clear distinction can be made between the location of soil waste, domestic waste or skip type waste materials found at higher elevation on site and the materials found at lower elevations in terms of being able to zone the presence and depth of specific waste materials on the site. Although domestic waste was encountered in TP101 and TP102, it was not encountered in WS107, WS108 or WS109 which were of a similar elevation. Domestic waste was also encountered in TP112 which was located at a higher elevation than TP101 and TP102. It is considered that the domestic waste materials encountered on site post-date 2010 based on a crisp packet best before date of 2011 identified on site. The different materials encountered on site did not indicate any clear patterns with regards to deposition laterally or vertically within the investigation positions undertaken on the site. As expected with such sites, the underlying waste was found to be heterogeneous indicating either potentially random locations of deposition at varying times or significantly varying materials during periods of deposition. In terms of the investigation works undertaken on site to date and presented herein it should be noted that only a limited number of positions have been undertaken on large site which is noted to be highly variable in nature.

Table 5.3 Summary of Groundwater Encountered within Monitoring Wells As can be seen from a review of the well levels (at ground level) presented in m AOD, WS107c, WS108b and WS109b, which were noted to be dry over the monitoring period, were noted to be located at a higher levels than other wells where water/leachate was noted to be present. Based on the water levels and that the water was often encountered within the clay based Made Ground it is likely that these represent perched groundwater/leachate pockets on site within or above less permeable strata. WS104, WS105 and WS106a may be representative of water trapped in the unslotted base of the installation, where a sump has effectively created a pathway for trapped porewater/leachate rather than representative of continuous groundwater or perched water at this location beneath the site.

Ground Investigation Report

It should be noted that there was heavy precipitation during the purging event therefore the recharge water may be indicative of perched water rather than a continuous groundwater body at shallow depth beneath the site. 5.4

Monitoring

Personal gas monitors which could detect combustible gases and vapours, as well as O2, CO, NO2, SO2 and H2S were used for the duration of the investigative works. These monitors were not triggered by encountered/excavated materials on the site. A radiation contamination monitor was also used during site works. The monitor was swept over the arisings and towards the excavations. The readings recorded were never above measured background levels. The background levels were ascertained from the user manual and double checked at the office ahead of completing site works. 5.5

Surface Water

The nearby Common Watercourse surface water has not been sampled due to access constraints. The watercourse is overgrown and therefore unsafe to access. If access improves over the winter months (vegetation dies back) it may be possible to sample Common Watercourse. In lieu of access to the nearby surface water, water samples were taken from the installed boreholes on site where available to assess potential movement of contaminants. 5.6

Obstructions

Boulder sized concrete and brick fragments were encountered in multiple trial pits across the site. Only TP109, TP111 and TP113 did not encounter boulder sized particles. WS106 encountered an obstruction at 2.2m, WS107, WS107a and WS107b all encountered obstructions between 0.50m and 0.65m, WS108 and WS108a encountered obstructions at 0.5m and WS109 and WS109a encountered obstructions at 0.5m. WS109b encountered an obstruction at 3.2m. Boulder sized pieces of concrete were observed at the surface across the majority of the site. 5.7

Physical Restrictions

Due to the nature of the site, access was difficult and required de-vegetation and access tracks to be constructed. This included tracks and vegetation removal to the rear of the compound for locations TP110 to TP113 and WS103 to WS106. Access to the southern end of the site needed to be made by cutting through a southern bund and construction of a track to the lower southern levels and locations TP110, TP111 and WS103. Access to WS106 also required excavation through a bund. Location TP107 was relocated further north to avoid a bund and significant sharp drop in level. Finally, TP108 was relocated east as the original location was within a steep sided deep trench. Tall dense brambles had to be removed to create access for WS107 and WS108 locations. A summary of encountered materials and constraints is presented in Figure 5. 5.8

Distinguishing Materials

It has been speculated by the Local Authority that the top of the original permitted landfill on site following restoration was potentially similar to the current level of the Launders Lane Road. Unfortunately, it has not been 35 GE21483/GIRv2.0/DEC23

Arnold’s Field, Launders Lane, Rainham, RM13 9GJ London Borough of Havering Council

Ground Investigation Report

possible through the works undertaken to date to obtain any records to verify the original restoration levels of the site following the initial permitted landfilling on the site. From the limited data collected and the lack of datable material it is impossible to ascertain with certainty which material encountered was from the original licensed landfill and which was from the subsequent unauthorised deposits of tipped waste, with the exception of TP112 which encountered a crisp packet which had a best before date of 2011. As part of these works it has not currently been possible to locate and records of the former capping details for the site, so it is unknown whether the original landfill was capped/restored and if so with what materials and to what levels. However, given the date of the landfilling it is expected that a thin restoration capping layer would likely have been applied to the site. However, it is difficult to assess the specific materials which may form the former capping system as no records are available on the final site levels following permitted filling and subsequent restoration. It is possible that the domestic waste encountered in TP101 and TP102 was from the original permitted landfill, despite the original permit not including domestic waste. However, with no dates on items excavated, this cannot be verified. If the original top of the permitted landfill was at the same level as the Launders Lane then material identified in WS102, WS103, TP110 and TP111 were likely part of the original landfill. It was noted during a return spot gas and water/leachate monitoring visit on site that additional waste (materials that could be carried by hand, e.g. a toaster), had been brought onto site near WS103 after the initial site investigation was completed (i.e. between the investigation works and monitoring works being undertaken on the site). It would be prudent to undertake a topographic survey completed across the whole site to understand the current site levels and provide current baseline levels allowing assessment of any changes as a result of any unpermitted fly tipping, stability issues/settlement associated with the variation in waste types and thicknesses across the site or changes in compaction. 5.9

Chemical Analysis

In order to assess the general chemical quality of the Made Ground encountered, samples of soils recovered from the exploratory holes were submitted for analysis for a range of potential contaminants supported by CLR publication CLR8 and Environment Agency R&D66 publication. The testing rationale included sampling and analysis to provide a general coverage of the subject site. Testing was undertaken for a broad range of commonly occurring contaminants including metals, metalloids, inorganic compounds, PCBs, speciated TPH, PAH, asbestos and some organic compounds and included analysis of the differing Made Ground strata encountered.

COMBUSTIBLE MATERIALS CONSIDERATIONS

Due to the high number of fires reported on the site, Geo-Environmental were asked to assess what buried materials were likely to be igniting or susceptible to fire. The following sections explore the materials encountered on site. Combustible materials have a flashpoint of between 38.7°C and 93.3°C (flammable materials have a flashpoint below 37.8°C). In this report is it assumed that a proportion of the encountered domestic waste have the potential to be combustible, however no testing has been completed to discern their flashpoint in this respect. 6.1

Potentially Combustible Materials Encountered

Household waste, containing materials considered to have the potential to be include potentially combustible material was encountered in TP101, TP102, and TP112. Materials classified as potentially flammable were identified in TP110 though analysis undertaken and an assessment of the materials through HazWasteOnline. The details of the materials are presented below. Location

NOTE: No level available for TP112, level extrapolated from nearby WS104. No level available for TP110. Note * In TP101 the soils at 1.20-3.20m bgl have the higher potential to be combustible in this location, however the materials noted above at 0.801.20m have elements that could also be combustible if a fire was started in the deeper materials and would burn with pockets of domestic waste and soils across the pit so have been referenced herein for completeness.

Table 6.1: Combustible Materials Encountered

These materials were encountered in deep trial pits. TP102 was relatively close to the “smouldering trench”, identified as part of the 8th August 2023 site walkover and detailed in the site description and understood to be subject to a historical fire on site, which could indicate that similar materials are present at depth in the trench. 38 GE21483/GIRv2.0/DEC23

Ground Investigation Report

Materials in Sample TP110 at 3.40m were classified as having potentially flammable properties (based on the recorded total TPH) in the HazwasteOnline Assessment, which assesses materials for waste classification. Trommel Fines were also identified on the surface in the southern area of the site. Trommel Fines are final materials that come from the mechanical treatment of waste. This material can be made up of some combustible components but are often formed mainly of glass, stone and soils, which would not necessarily be regarded as a combustible material. However, the materials have a very low density and can contain fine particles of timber, plastic etc and due to this a large surface area. They are also difficult to compact and can become quite spongy, thus allowing the flow of oxygen through their matrix. Due to their large surface area, low density and ability for oxygen flow, once ignited, these materials could remain ignited and spread fire throughout the areas where they have been deposited. Although trommel fines were only identified in one specific area (see Figure 5) it is possible that there are more tipped on site, either at the surface or buried. It is also considered that visual identification of these materials was likely to have been hindered by areas of vegetation on site. Their exact composition can vary and, due to their physical properties, can often be costly to dispose of through legitimate routes. It should be noted that although combustible materials were identified at depth an obvious heat source/ignition source was not encountered. The possible presence of LPG canisters as an ignition source was previously raised by the Council, local residents at the public meeting on the 1st September, and within the 3rd party GEMCO Phase 1 assessment report. However, significant evidence of these was not identified as part of the intrusive works undertaken on site, albeit that the total number of investigation positions undertaken only assessment a small proportion of the overall site, in terms of deposited materials. Possible evidence of subsurface fires was observed in TP108 where charred plastic and metal was observed between 1.00m bgl and 1.30m bgl. From these observations alone it is impossible to say with any certainty whether the material was charred on deposition or if there had been a subsurface fire. The charred material was isolated in nature within the trial pit. Photos of the materials encountered within each of the investigation positions are presented in Appendix B. 6.2

Asbestos

Laboratory testing identified loose asbestos fibres were present in deep and shallow soils across the site. Loose fibres in the shallow soils and on the surface of the site may pose a potential health risk to nearby residents. Theoretically loose fibres could migrate from the site in strong winds or entrained in smoke from fires and be transported to surrounding areas. Geo-Environmental are unaware of any studies determining how far asbestos fibres can travel in these situations and therefore unable to advise whether this does pose a practical risk to the nearby residents. Suspected cement bound asbestos was identified on the surface across the site however, cement bound asbestos is notably non-flammable and non-combustible and was often used as a fireproofing material therefore the risk from these discrete fragments is very low.

Ground Investigation Report

It is recommended that asbestos air monitoring is undertaken in areas across the site to further assess the presence of loose fibres were identified to understand if fibres are potentially being transported offsite. Whilst it is recommended that air monitoring is undertaken on/around the site to inform further assessment of the potential for airborne fibres to be released to the air, where asbestos is bound within cement, or mixed within a soil mass, it is considered that there is negligible potential for fibres to be released.

Ideally further monitoring would be undertaken to form a baseline for the site and to consider if/when further fires break out on site to identify any potential fibres within the smoke. 6.3

Surface Fires

Evidence of recent surface fires was observed in the southwest of the site along the boundary with New Road. Charred material was encountered across much of the southern boundary with New Road and a pile of material was still smouldering while the Geo-Environmental Engineers were on site. The pile was not in close vicinity to the working area and was dealt with by Geo-Environmental and GEMCO (the Landowner’s Consultant), with both parties agreeing on site that an appropriate course of action to mitigate the potential risk identified. As such, it was requested that the excavator driver on site dig a fire break trench around these materials. Charred materials included but were not limited to metal (food cans, scrap metal), wood (possibly treated and untreated timber), plastic (bags and solid plastic items), brick, cardboard, paper, rubber (wellington boots), textiles (clothing, carpets) and foam. It should be noted that although charred materials were observed, no evidence of an ignition source were identified in proximity to the material. 6.4

Trommel Fines

Trommel fines were identified in an area in the south of site. Trommel fines are the final materials that come from the mechanical treatment of waste. This material can be made up of some combustible components but are often formed mainly of glass, stone and soils, which would not necessarily be regarded as a combustible material. However, the materials have a very low density and can contain fine particles of timber, plastic etc and due to this a large surface area. They are also difficult to compact and can become quite spongy, thus allowing the flow of oxygen through their matrix. Due to their large surface area, low density and ability for oxygen flow, once ignited, these materials could remain ignited and spread fire throughout the areas where they have been deposited. Although trommel fines were only identified in one specific area it is possible that there are more tipped on site, either at the surface or buried, it is also considered that visual identification of these materials was likely to have been hindered by areas of vegetation on site. Their exact composition can vary and, due to their physical properties, can often be costly to dispose of through legitimate routes.

ENVIRONMENTAL CONSIDERATIONS

A Generic Quantitative Risk Assessment (GQRA) of risks to the adjacent land users utilising the results of the ground investigation was undertaken, the findings of which are presented in the following sections. 7.1

Ground Gases

We have assumed that our monitoring wells have been left untouched between monitoring visits and that gas has accumulated sufficiently between visits. If gas valves were opened between monitoring visits, or wells vented in any other way, the results of the monitoring may not be representative of the gas regime of the site. Gas and groundwater monitoring wells were installed within locations WS101, WS102, WS103, WS104, WS105, WS106a, WS107c, WS108b, WS109b and WS110. Monitoring has been undertaken on six occasions on 3rd, 13th, 27th October, 6th and 20th November, and 4th and 6th December 2023. The final monitoring visit was split into two due to unforeseen issues with the technician’s vehicle. All programmed monitoring visits are now complete. The construction of the monitoring wells is summarised in Table 7.1. It should be noted that all of the monitoring wells installed on site are considered to have response zones located within the Made Ground. Location WS101 WS102

The spot monitoring undertaken detected methane at concentrations in the range of 0.0% to 33.4%. Carbon dioxide has been detected at concentrations in the range of 0.1% to 30.2% and oxygen in the range 0.1% to 22.0%. Volatile Organic Compounds (VOCs) have been detected at concentrations of between 0.0ppm to 302ppm during the monitoring visits. Atmospheric pressure was recorded in the range of 991mb to 1020mb during the visits undertaken. Borehole flows were measured and recorded a steady flow of -0.2 to 1.2 l/hr. Carbon monoxide was detected at concentrations ranging between 0ppm and 12ppm, hydrogen sulphide was recorded at concentrations between 0.0ppm and 61ppm. The maximum readings recorded during each of the monitoring visits undertaken to date are summarised in the Table 7.2 below.

Table 7.2 Summary of maximum Gas Readings

It is likely that the elevated gasses are being produced by isolated pockets of specific material, rather than present across the site. The gas monitoring has identified elevated levels of ground gases including methane, carbon dioxide, hydrogen sulphide and VOCs however, no significant flow has been recorded, in addition variation in concentrations was noted between monitoring points on site with the highest levels in the wells located at a lower level (AOD) so potentially associated with the underlying former landfill. The build-up of methane gas could result in a flammable source within pockets where the gas in collecting (although an ignition source is still required (e.g. heat or flame). 7.1.1

Gas Risk Assessment

Ground gas monitoring wells were installed across the site to target onsite landfill materials. Soil samples were also collected from the site from the underlying Made Ground and were submitted for analysis of Total Organic Carbon to aid with the ground gas risk assessment. The intrusive investigation did not encounter conditions that required a revision of the preliminary risk assessment presented within the desk study section of this report. A Tier 1 Ground Gas Risk Assessment (GGRA) incorporating the results of the desk study and ground investigation was undertaken, the findings of which are presented in the following sections. 7.1.2

Ground Gas Sources

The desk study has identified the potential for ground gases and vapours associated with the former on-site landfill site and unauthorised deposited waste materials, together with a risk from organic rich waste that may be present onsite and the potential for methane generation within the on-site waste materials. The onsite landfill is recorded as having accepted domestic waste and if/where present this represents a high potential source of methane. Migration of gas and vapours to the site from former landfill sites to the north, south and west of the site is also potentially possible. These landfill sites represent a potential source of ground gas due to the types of wastes that were permitted and deposited. The anticipated natural geology underlying the site comprises a succession of Alluvium, Head Deposits and Taplow Gravel overlying the London Clay Formation. The underlying London Clay bedrock geology is primarily formed of impermeable clay layers and as such is unlikely to represent a plausible migration pathway for ground gases. It is unknown at this stage if the historical pit was formally lined or not. Given the age of the site and underlying geology comprising London Clay it is possible that a formal lining was not installed. However, the superficial deposits may contain permeable layers that could represent a plausible lateral migration pathway. Notwithstanding this, it is anticipated from review of the site’s history, that much of the sand and gravel within the site was extracted and replaced with overburden and landfill wastes. The permeable strata are still likely to remain present around the periphery of the site as some form of gravel pit benching, or battered sides required to maintain a stable site boundary. It is therefore possible that gas generated from off-site and on-site landfills could migrate and mix. 43 GE21483/GIRv2.0/DEC23

Arnold’s Field, Launders Lane, Rainham, RM13 9GJ London Borough of Havering Council

Ground Investigation Report

Given the known history of the site, it is considered that there is potential for bulk gases such as methane, carbon dioxide and oxygen to be present together with trace gases such as hydrogen sulphide, carbon monoxide, VOCs and the like associated primarily with the historical landfill materials at depth on the site. Any occurrence of subterranean fires and the introduction of water into the landfill body are likely to cause variation in the composition of gases and vapours within the landfill waste mass over time. In addition, flow conditions are also likely to vary. 7.1.3

Total Organic Carbon

An assessment of TOC was undertaken on the Made Ground soils recovered from the exploratory hole positions on site in order to provide a further assessment of the background/baseline potential for ground gases to be present on the subject site associated with the underlying encountered landfill material, prior to consideration of potential external sources. TOC gives a conservative estimate of the amount of biodegradable material in waste or soils. It includes both readily available carbon that degrades relatively quickly and non-readily available carbon that will breakdown and degrade very slowly. A selection of soils samples collected from across the subject site were sent for geochemical laboratory analysis for % TOC. The results identified concentrations of TOC across the site between 0.8% and 2.4%, with an average of 1.33%. CL:AIRE RB17 and BS8485:2015 use TOC results to classify a site in terms of anticipated gas risk. For recently placed material a TOC of <1% indicates a classification of Characteristic Situation 1, <1.5% indicates Characteristic Situation 2, and <4% indicates Characteristic Situation 3. The average recorded concentration of TOC on this site is 1.33% therefore the overall results indicate that the site is Characteristic Situation 2 based solely on TOC on the subject site itself. However, it should also be noted that the guidance relates to the placement of fresh waste, and domestic landfill type material was only identified as being present within locations TP101, TP102 and TP112 from the recent investigation works undertaken. However, an assessment of the TOC serves to provide a background assessment for the site for the potential for presence of ground gases ahead of taking account of any potential migration from external sources identified. 7.1.4

Assessment of Gas Monitoring Data

An assessment of the maximum concentrations of recorded hazardous gas recorded and gas flow rates recorded within the return monitoring for the site has been undertaken. Chart 1 below shows the variation in maximum methane concentrations with each monitoring well through the monitoring period undertaken as part of this phase of works.

Boreholes WS101, WS102 and WS103 have consistently recorded the highest concentrations of methane across the monitoring period. These boreholes are located in the south east and south of the site, and it is thought that these boreholes were located within the historic permitted landfill present on the site. Boreholes WS106a and WS107c were located in the west of the site in areas of the site where it is understood materials including landfill materials may have been relocated/pushed during previous restoration/reprofiling works. Atmospheric pressure does not appear to have influenced the concentrations of methane being recorded.

Chart 2 Variation in maximum Carbon Dioxide concentrations over the duration of the gas monitoring period It can be seen that carbon dioxide was recorded in all standpipes over the monitoring period, with boreholes WS101, WS102, WS107c and WS108b consistently recording the highest concentrations. Boreholes WS101 and WS102 were located in the east of the site near to the current site entrance. These boreholes were located either side of an area of hardstanding, therefore, this area of hardstanding is likely to be preventing the venting of gases to atmosphere which may have led to the increased concentration of gas encountered within WS101 and WS102 recorded. Boreholes WS107c and WS108b were located in the west of the side adjacent to a bund followed by a significant drop possibly marking the edge of the former permitted landfill area. Chart 3 below shows the variation in minimum oxygen concentrations with each monitoring well through the monitoring period.

Chart 3 Variation in minimum Oxygen concentrations over the duration of the gas monitoring period It can be seen that boreholes WS101 and WS102 regularly record oxygen concentration of less than 2%. With the exception of the first visit borehole WS103 can also be seen to have recorded oxygen concentrations of less than 2%. Oxygen concentrations are seen to vary in the other boreholes located across the site, however concentrations are generally lower than atmospheric concentrations within the majority of the boreholes. The lack of oxygen or lower concentrations of oxygen recorded within the boreholes across the site indicate a lesser risk of the occurrence of trommel fires in these areas. Concentrations of carbon monoxide and hydrogen sulphide were also recorded within each of the monitoring wells with the highest concentration of carbon monoxide being identified within WS107c at 12ppm, and the highest concentration of hydrogen sulphide being identified within WS101 at 61ppm. In addition, the highest concentration of VOCs were recorded within WS102 at 302ppm, however, this concentration appears to be an anomaly as all other recorded concentrations were between 0.9 and 60.2ppm within all of the monitoring wells. Negligible positive gas flow rates were recorded within boreholes, WS101, WS102, WS104, WS105, WS106a, WS107c, WS108b and WS109b on a number of occasions. The lack of notable flow indicates that the source of the methane and carbon dioxide are migrating by diffusive flow only. Gas primarily migrates via either pressure driven (advective) flow or via diffusive flow. The borehole flow rates recorded across the site during the monitoring period are consistently negligible. As such, gas present beneath the site will diffuse through the soils forming a continuum between the source and ground level, with only minor concentrations of gas reaching ground level, and no perceivable flow. The majority of gas will remain trapped in the soil pores or sorbed to soil particles. The flow rate recorded within WS106a on 4th December 2023 appears to represent a spike or anomaly. Although 47 GE21483/GIRv2.0/DEC23

the recorded flow rate is negligible it appears to be higher than any other flow rates recorded. Looking at atmospheric pressure conditions on the date of this monitoring round and the days preceding it, atmospheric pressure appears to be low at the time of the monitoring round and was falling to steady in the days preceding the monitoring round. Therefore, it is considered that atmospheric pressure may have impacted the recorded flow rate, and that it may be representative of a worst-case scenario. Assessment of the construction of the wells and the underlying ground conditions has shown that all of the response zones of the installed wells were solely within the Made Ground materials beneath the site. Description of this Made Ground material was shown to vary across the site. The highest concentrations of methane and carbon dioxide were found within WS101 and WS102, with WS103 identifying high concentrations of methane. These boreholes were located in the south east and south of the site and are thought to be located within the historic permitted landfill material. Elevated concentrations of carbon dioxide were also identified within WS107c and WS108b which were located in the west of the site adjacent to a bunded area thought to possibly represent the edge of the historic permitted landfill. As such, it is considered that the elevated concentrations of methane and carbon dioxide identified across the site are being generated by the former historic landfill located on the site. In addition, the lack of oxygen or reduced concentrations of oxygen recorded within the boreholes where elevated methane has been identified identifies a lesser risk of trommel fires in these areas. The lack of notable flow indicates that the methane and carbon dioxide identified as being generated on the site are migrating by diffusive flow only. Therefore, it is considered, based on the monitoring undertaken to date, that there is a low migration risk of gases off site. 7.2

It should be noted that none of the maximum concentrations were derived from a sample taken from within the domestic waste, nor were they located directly under the charred tipped material in the southern area of the site. A Preliminary Quantitative Risk Assessment has been undertaken in order to evaluate any unacceptable risks posed to human health with respect to anyone accessing and walking around the site in its current state. It should be noted that this assessment does not evaluate the risks posed to human health with respect to construction or end users as this will be included in any remediation reports produced if and when an end use for the site has been identified. A quantitative risk assessment has been undertaken by comparing the results of the laboratory chemical testing of shallow soils against Tier 1 screening criteria in the first instance. These criteria comprise the Atkins ATRISK soil screening values (SSVs), the Suitable for Use Levels (S4ULs) published by LQM (Copyright Land Quality Management Limited reproduced with permission; Publication Number S4UL3453. All rights reserved) and the Category 4 Screening Levels (C4SLs) published by DEFRA. Although the C4SLs were released for Part 2A use, the associated policy companion document for the C4SLs indicated that they may also be used for planning. Although the C4SLs represent a marginally higher risk level than the SSACs (low risk rather than minimal risk) it is considered that the risk levels remain very low. Therefore, the final C4SLs are considered to be suitable to assess soils under the planning regime. The exploratory holes were located to provide general coverage of the site. Analysis was undertaken on soil samples collected from these exploratory holes. In the first instance the results of the sample analysis were compared to the Tier 1 screening criteria where available. The results were compared to criteria for Public Open Space (Park) as a conservative approach. Contaminant Arsenic

Table 7.5 Summary of Asbestos Positive IDs

Although the majority of the asbestos positively identified by the laboratory was located in deeper soils, suspected bonded asbestos cement fragments were noted in locations across the whole site. It is possible that wind disturbance could entrain any loose fibres at the surface and transport them offsite. It is recommended that air monitoring be carried out across the site and along the boundaries to monitor for the presence of any asbestos fibres (to assess potential mobility as a result of normal conditions on site/ though airborne release and movement). It is noted that once fibres are in the air, they could travel in the prevalent wind direction. 50 GE21483/GIRv2.0/DEC23

Waste Disposal

7.4.1

Deposited Soils

The soil analyses from the main site area were assessed using HazWasteOnline software. Most of the samples assessed were indicated to represent potentially non-hazardous waste with the exception of TP107 at 1.80m and TP110 at 3.40m as detailed below. The HazWasteOnline assessment for the main site area is included within Appendix G. It should be noted that any extraneous materials such as plastic, wood etc. present in the soils as observed will likely impact the waste classification. It may be possible to screen out such materials as part of any remedial treatment process. Details for the two hazardous samples are provided below: • •

TP107 at 1.80m – The following hazardous properties were identified: Carcinogenic (HP7) due to lead concentration, Toxic for reproduction (HP10) due to lead concentration and Ecotoxic (HP14) due to copper concentration, lead concentration and zinc concentration; TP110 at 3.40m bgl – The following hazardous properties were identified: Flammable (HP3) due to TPH concentration, Carcinogenic (HP7) due to TPH concentration, Mutagenic (HP11) due to TPH concentration and Ecotoxic (HP14) TPH concentration and zinc concentration.

It should be noted that asbestos cement fragments were identified within analysis in TP103 at 0.75m, TP106 (between surface level and 1.80m bgl and 3.00m and 3.40m bgl)) and TP104 (at surface level). As such, asbestos cement fragments and suspected asbestos cement fragments were observed across the site at surface and within the waste materials at depth. The presence of visible asbestos cement fragments and lagging identified on site and submitted for analysis (and any other forms of asbestos) identified from analysis in the soil or otherwise 52 GE21483/GIRv2.0/DEC23

Ground Investigation Report

potentially present across other areas of the site renders the soils a hazardous mixed waste. Some level of treatment such as handpicking of the ACMs would be required with a view to separating the asbestos and soils to reduce the volume of material required to disposed of as hazardous waste. However, this would only be possible for the likes of asbestos cement board, if/where significant volume of lagging for example was encountered it would be very hard to hand pick these materials to reduce the waste classification. However, further testing would be required to classify materials for offsite disposal, and ultimately classification of materials will be subject to an assessment of the test results and soil description by the receiving facility. Hazardous waste has been identified largely in relation to visible fragments of bonded asbestos cement within and on top of the soils. The removal of visible asbestos containing materials by processing or hand picking may serve to remove the hazardous properties from some of the soils (subject to post-processing testing and assessment). All work with asbestos containing materials and asbestos containing soils should be undertaken by a suitably competent contractor who should prepare an asbestos specific risk assessment detailing the control measures to be applied when working with the asbestos containing materials/soils. The contractor should also assess whether the work would be considered licensable and/or notifiable under the Control of Asbestos Regulations 2012. It should also be noted that trommel fines (mixed material resulting from waste transfer sites that ensues from sorting waste through large cylinder devices called trommels, which are intended to separate the material by size) were observed on site. No samples sent for analysis contained trommel fines. Should offsite removal be considered for these materials then testing of trommel fines should be undertaken to confirm the exact waste classification disposal/treatment requirements and their presence highlighted to the receiving facility, and ultimately the classification of materials will be subject to an assessment by the receiving facility. The location of the trommel fines identified on site to date is presented in Figure 5. 7.4.2

Domestic waste

The soil analysis from the soils mixed in with the domestic waste materials was sampled and the analytical results were assessed using HazWasteOnline software. The sample was assessed as non-hazardous waste (this presents an indication of the classification of the fine grained soil materials for the purpose of disposal). However, it should be noted that any extraneous materials such as plastic, wood etc present in the soils as observed could impact the waste classification which may then increase the classification. Furthermore, the presence of an Asbestos containing materials (ACMs) or the presence of asbestos fibres within the soils which are quantified above 0.1% would likely render the materials as hazardous waste for the purpose of disposal.

CONCLUSIONS AND RECOMMENDATIONS

In conclusion, based on the limited data available from a review of the desk study information and from the intrusive investigation works, with the exception of TP113, it has not been possible to formally determine whether materials encountered as part of the intrusive investigation positions are part of the original permitted landfill or unauthorised tipping above. Although some inferences can be made based on areas of the site being significantly topographically higher than others, no details as to the finished levels of the original permitted landfill levels have been identified or reviewed as part of these works. A review of historical photographs for the site (From Google Earth) indicated that earthworks were undertaken on the site at the time of the unauthorised deposition of wastes, which may have moved the permitted landfilled materials from their original placement locations. TP113 can be approximately dated due to the presence of crisp packets with expiry dates still noted to be readable (2011). In addition, areas of waste material were noted at surface level across the majority of the site which are inferred to be unauthorised deposits tipped materials. While multiple potentially combustible materials were encountered both on the surface and in the soils/waste mass, no significant evidence of ignition sources were identified within the soils or waste mass encountered within the exploratory hole positions undertaken. No evidence of LPG canisters was identified as previously considered to present a potential ignition source on the site. They may be present in other areas of the site remote from the investigation positions undertaken. As such, it has not been possible to identify a definite ignition source on the site as part of the works undertaken to date. Charred surface items were observed in the southern portion of the site, including but not limited to metal, plastics and textiles. This area of the site was noted to be subject to several fires the week prior to investigation works commencing on site. In addition, a smouldering trench was identified during the initial site walkover on the site in August 2023 within the central portion of the site, in an area which was noted to have been subject to an historical large fire on site. The trench, that had been dug to attempt to suppress the fire, appeared to contain similar waste type materials to the domestic waste encountered within TP102. Neither the personal gas monitors nor the radiation monitor on site identified elevated levels/levels of concern during the intrusive investigation works undertaken. Return spot gas monitoring of the monitoring standpipes installed within the waste mass on site have identified levels of methane, carbon dioxide, carbon monoxide, hydrogen sulphide and VOCs along with depleted oxygen on site, such that the presence of methane where elevated may be acting to exacerbate and sustain fires on the site within the deposited waste materials. Methane is flammable and explosive between certain limits and the presence of pockets of methane could potentially exacerbate or sustain fires, however an ignition source (e.g. arc/flame/heat would still be required). However, without a source of ignition and with no significant flow, the methane would be likely to remain within the waste mass and concentration reduce towards ground surface. In addition, depleted oxygen concentrations were recorded across the site within the monitoring wells, thereby a reduction in oxygen is considered to reduce the risk of sub terranean fires as oxygen would be needed to enable a fire to burn. It is noted that no significant flow has been detected in terms of ground gases and as such the risk to offsite receptors from ground gas migration is considered to be low. It is suggested that further detailed assessment of gas regime may be beneficial in further assessing the site in order to further to consider the potential for a build-up of gases in pockets across the site and to further assess the presence of ground gases venting from the site. This further assessment is suggested to include continuous gas monitoring, a surface emissions survey and additional TOC analysis of encountered Made Ground materials. Continuous gas monitoring would provide further data in relation to fluctuations in recorded gas concentrations 54 GE21483/GIRv2.0/DEC23

Ground Investigation Report

and gas flow rates in real time. A surface emissions survey would help to identified areas of the site where gases are venting to atmosphere, aiding to identified areas of the site where pockets of gases are located. Additional TOC analysis of the Made Ground underlying the site would help to provide further assessment of the likely gassing potential of the Made Ground materials located across the site to aid to target areas where gases are most likely to be generated. In addition, it may be prudent to consider the drilling of some deep boreholes in order to locate monitoring wells solely within the former permitted landfill, as this appears to be the main source of gases encountered across the site. It should be noted that the proposed options are with a view to assessing the current status and gassing regime on the site. It should be noted that any works on site such as regrading, capping or subsequent development if proposed would be considered to alter the gassing regime of the site and would need to be considered further in the context of any works proposed. The majority of the soils element encountered are considered to be suitable to be left in-situ beneath the site in terms of risk to human health with regards to public open space (taken as the most conservative end use given the unauthorised access to a private site). While contaminants have been identified including TP110 at 3.40m bgl, TP106 at 2.20m bgl, TP103 at 0.75m bgl and WS107c at 2.30m bgl which had exceedances in arsenic, lead and PAH respectively these were generally noted to be present at depth, such that where the soils remain undisturbed there is not significant risk in terms of risk to human health from the general existing site use. However, the presence of other elevated contamination concentrations associated the waste materials/soils at shallow depth across the site surface cannot be ruled out given the significantly variable nature of the materials and contamination levels identified within the samples analysed. As such, to reduce the risk of unauthorised entry to the site is it recommended that the site is secured. Further consideration would need to be given to the presence of ACMs identified on the surface and in shallow soils beneath the site, together with seemingly sporadic low concentrations of free fibres identified within the soils. Whilst it is recommended that air monitoring is undertaken on/around the site to inform further assessment of the potential for airborne fibres to be released to the air given asbestos was identified both on the surface and in the subsurface soils on site. Were asbestos is bound within cement, or mixed within a soil mass, it is considered that there is negligible potential for fibres to be released. It is considered that the risk to members of the public from the elevated concentrations of specific determinands could primarily be mitigated through securing the site to prevent unauthorised access thereby breaking the source-pathway-receptor for exposure to the contaminants on site. Water/leachate samples found exceedances (when compared to Environmental Quality Standards (EQS) for Freshwater) in relation to arsenic and PAH in TP110 at 3.50m bgl and Boron, Mercury and Chloride in WS102 at 3.18m bgl. It is thought that these are likely to be isolated pockets of perched water/leachate which has been impacted by waste localised to the area of the monitoring wells. While a continuous water body has not been identified beneath the site within the Made Ground materials/soils to 5m bgl, the nature of the site is such that infiltration of rainfall will occur on the site, which is likely to result in localised leaching of contaminants and pockets of water/leachate forming which have the potential to migrate. The original scope of works for the site did include the proposed monitoring of the nearby surface water Common Watercourse which boarders the site to the west and north. However, due to the overgrown nature of the site and limited access to date, it has not been possible to safely undertake surface water monitoring. As such, works have focused on assessing the potential for leachable contaminants. During the site works no evident of breakout of leachate was noted in relation to the site, however the overgrown nature of the site could have obscured any such occurrences. The leachability and presence of water within the waste mass/soils on site is considered to be a function of infiltration through the site. As such, in order to reduce the leaching of contaminants and potential migration through the site or to off-site receptors, consideration could be given to providing a capping layer on site formed

Ground Investigation Report

from a less permeable material with surface water channelled over the site to discharge into the adjacent surface water as opposed to being allowed to infiltrate through the site and waste materials. Any detailed proposals for capping of the site to reduce infiltration would also need to consider ground gases in further detail to assess any potential to changes to the gassing regime on site as a result of installing a capping system. Although some of the soils analysed on site were classified as non-hazardous waste (when considered in relation to waste classification for disposal) two samples were found to be hazardous (TP110 3.40m and TP106 2.20m). This classification is based on the chemical properties of the materials. It should be noted that any extraneous materials such as plastic, wood etc present in the soils as observed could impact the waste classifications. The presence of asbestos bonded fragments in soils also impacts the waste classification. It is recommended that the following works be undertaken to further assess or reduce the potential for significant risk of significant harm in relation to the site. •

• •

Asbestos air monitoring on the site to assess the potential of airborne asbestos fibres and any associated risk of migration. Recommended to comprise boundary monitoring as well as within the site. It should be noted that due to the topography on site, boundary monitoring may require access to adjacent land to safely access the site boundaries. Securing of the site to prevent unauthorised access, thereby breaking a number of the source, pathway receptor linkages identified; Consideration of reprofiling and capping of the waste materials on site to further mitigate potential source pathway receptor linkages identified to reduce the risk from the current status on site.

It is also suggested that the following works could be undertaken to aid further assessment of the gassing regime on site and key risk drivers with a longer term view of assessing options for works required toreduce the potential for significant risk of significant harm in relation to the site, in the context of the current land use and any subsequent proposed land use.. •

Further assessment of ground gas regime on the site and potential for methane to comprise a flammable source for fires on site in the form of: o Continuous gas monitoring to monitoring gas concentrations and flow rates in real time. o Surface emissions survey across the site to aid identification of areas of the site where gases are being produced. o Additional TOC analysis of Made Ground soils to help identified areas where the risk of future gas generation is considered higher. o Drilling of deep boreholes to target the historic permitted landfill material.

It is possible that the risks posed by the site could be reduced by leaving the material on site and capping it to break the pathway between source and receptor, prevent any asbestos fibres from leaving site and to starve any combustible material of oxygen to prevent fires. It is likely that any remediation required to make the site suitable for a specific development or change in end use would differ from the works proposed in terms of reducing any risk in relation to the current site status and this would be subject to a further assessment which is beyond the scope of the works presented herein. It should however, be noted that any changes to the site whether that is capping or incorporation of areas of hardstanding will impact on the sites gassing regime and detailed assessment would be required prior to the undertaking of any such works.

Ground Investigation Report

8.1

Status under Part 2A

The site-specific assessment has provided additional information with which to re-assess and further characterise the reasonable possible pollutant linkage groups identified within the Preliminary Risk Assessment (PRA). With regards to human health (regulated by the Local Planning Authority) and controlled waters (regulated by the Environment Agency), contaminant linkages should be considered as ‘significant contaminant linkages’ only where it can be demonstrated that they will result in a ‘significant possibility of significant harm’, often referred to as SPOSH. The strict legal test of SPOSH is where site conditions are such that exposure to the contaminant, and thus the contaminant linkage, would represent an unacceptable intake or other bodily contact assessed on the basis of information on the toxicological properties of that contaminant. The assessment of SPOSH is a regulatory decision and, in relation to human health, should be taken by the Local Authority and/or Environment Agency dependant on receptor. It is considered that the overall risk of the site (when not on fire) in relation to a number of the source pathway receptor (SPR) linkages identified could be reduced by securing the site, thereby removing unauthorised access on the site. However, further consideration is required in relation to the SPR linkages associated with the fires on the site, both during fires and of any impacts following fires. In addition, there are areas where a significant risk of significant harm has not currently been identified but that improvements or limited works on site such as reprofiling and installation of capping across the exposed waste materials, resulting in a reduction of infiltration through the site may also serve to offering a reduction in overall risk.

Dear Tom Thank you for your enquiry of 15 June 2023. Having reviewed our case file, we do not hold any permits, and/or Compliance Assessment Reports. We have no records of any surveys and/or sampling results for the site within the historic casefile. We are aware from our investigation at the site, that between 2011 and July 2014 there was extensive deposits of non-hazardous waste at site, approximately between 30 to 50,000 cubic meters. Waste consisted of mixed household, commercial and industrial material, suspected from a waste transfer station. We took prosecutions against three offenders, who were convicted for the deposits. I hope that we have correctly interpreted your request. We respond to requests for recorded information that we hold under the Freedom of Information Act 2000 and the associated Environmental Information Regulations 2004. This information is provided subject to the Open Government Licence, which you should read. Please get in touch if you have any further queries or contact us within two months if you’d like us to review the information we have sent. Yours sincerely

We are also aware that since it has been used as a mixed landfill site of various waste types.

Recommendation

It is recommended that a detailed desk study is commissioned to assess, and potentially zone, the Unexploded Ordnance (UXO) hazard level on the Site.

Further information

For information about Zetica’s detailed UXO desk studies and other UXO services, please visit our website: www.zeticauxo.com. Details and downloadable resources covering the most common sources of UXO hazard affecting sites in the UK can be found here. If you have any further queries, please don’t hesitate to get in contact with us at uxo@zetica.com or 01993 886 682.

This summary is based on a cursory review of readily available records. Caution is advised if you plan to action work based on this summary. It should be noted that where a potentially significant source of UXO hazard has been identified on the Site, the requirement for a detailed desk study and risk assessment has been confirmed and no further research will be undertaken at this stage. It is possible that further in-depth research as part of a detailed UXO desk study and risk assessment may identify other potential sources of UXO hazard on the Site.

5.3 Groundwater vulnerability Records within 50m

An assessment of the vulnerability of groundwater to a pollutant discharged at ground level based on the hydrological, geological, hydrogeological and soil properties within a one kilometre square grid. Groundwater vulnerability is described as High, Medium or Low as follows: High - Areas able to easily transmit pollution to groundwater. They are likely to be characterised by high leaching soils and the absence of low permeability superficial deposits. Medium - Intermediate between high and low vulnerability. Low - Areas that provide the greatest protection from pollution. They are likely to be characterised by low leaching soils and/or the presence of superficial deposits characterised by a low permeability.

Ambiental Risk Analytics surface water (pluvial) FloodMap identifies areas likely to flood as a result of extreme rainfall events, i.e. land naturally vulnerable to surface water ponding or flooding. This data set was produced by simulating 1 in 30 year, 1 in 100 year, 1 in 250 year and 1 in 1,000 year rainfall events. Modern urban drainage systems are typically built to cope with rainfall events between 1 in 20 and 1 in 30 years, though some older ones may flood in a 1 in 5 year rainfall event. Features are displayed on the Surface water flooding map on page 62 > The data shown on the map and in the table above shows the highest likelihood of flood events happening at the site. Lower likelihood events may have greater flood depths and hence a greater potential impact on a site.

9.1 Groundwater flooding Highest risk on site

Moderate

Highest risk within 50m

Groundwater flooding is caused by unusually high groundwater levels. It occurs when the water table rises above the ground surface or within underground structures such as basements or cellars. Groundwater flooding tends to exhibit a longer duration than surface water flooding, possibly lasting for weeks or months, and as a result it can cause significant damage to property. This risk assessment is based on a 1 in 100 year return period and a 5m Digital Terrain Model (DTM).

10.15 Nitrate Sensitive Areas Records within 2000m

Areas where nitrate concentrations in drinking water sources exceeded or was at risk of exceeding the limit of 50 mg/l set by the 1980 EC Drinking Water Directive. Voluntary agricultural measures as a means of reducing the levels of nitrate were introduced by DEFRA as MAFF, with payments being made to farmers who complied. The scheme was started as a pilot in 1990 in ten areas, later implemented within 32 areas. The scheme was closed to further new entrants in 1998, although existing agreements continued for their full term. All Nitrate Sensitive Areas fell within the areas designated as Nitrate Vulnerable Zones (NVZs) in 1996 under the EC Nitrate Directive (91/676/EEC). This data is sourced from Natural England.

World Heritage Sites are designated to meet the UK's commitments under the World Heritage Convention. This data is sourced from Historic England, Cadw and Historic Environment Scotland.

11.2 Area of Outstanding Natural Beauty Records within 250m

Areas of Outstanding Natural Beauty (AONB) are conservation areas, chosen because they represent 18% of the finest countryside. Each AONB has been designated for special attention because of the quality of their flora, fauna, historical and cultural associations, and/or scenic views. The National Parks and Access to the Countryside Act of 1949 created AONBs and the Countryside and Rights of Way Act, 2000 added further regulation and protection. There are likely to be restrictions to some developments within these areas. This data is sourced from Natural England, Natural Resources Wales and Scottish Natural Heritage.

11.3 National Parks Records within 250m

In England and Wales, the purpose of National Parks is to conserve and enhance landscapes within the countryside whilst promoting public enjoyment of them and having regard for the social and economic wellbeing of those living within them. In Scotland National Parks have the additional purpose of promoting the sustainable use of the natural resources of the area and the sustainable social and economic development of its communities. The National Parks and Access to the Countryside Act 1949 established the National Park designation in England and Wales, and The National Parks (Scotland) Act 2000 in Scotland. This data is sourced from Natural England, Natural Resources Wales and the Scottish Government.

11.4 Listed Buildings Records within 250m

Buildings listed for their special architectural or historical interest. Building control in the form of 'listed building consent' is required in order to make any changes to that building which might affect its special interest. Listed buildings are graded to indicate their relative importance, however building controls apply to all buildings equally, irrespective of their grade, and apply to the interior and exterior of the building in its entirety, together with any curtilage structures.

11.5 Conservation Areas Records within 250m

Local planning authorities are obliged to designate as conservation areas any parts of their own area that are of special architectural or historic interest, the character and appearance of which it is desirable to preserve or enhance. Designation of a conservation area gives broader protection than the listing of individual buildings. All the features within the area, listed or otherwise, are recognised as part of its character. Conservation area designation is the means of recognising the importance of all factors and of ensuring that planning decisions address the quality of the landscape in its broadest sense. This data is sourced from Historic England, Cadw and Historic Environment Scotland.

11.6 Scheduled Ancient Monuments Records within 250m

A scheduled monument is an historic building or site that is included in the Schedule of Monuments kept by the Secretary of State for Digital, Culture, Media and Sport. The regime is set out in the Ancient Monuments and Archaeological Areas Act 1979. The Schedule of Monuments has c.20,000 entries and includes sites such as Roman remains, burial mounds, castles, bridges, earthworks, the remains of deserted villages and industrial sites. Monuments are not graded, but all are, by definition, considered to be of national importance. This data is sourced from Historic England, Cadw and Historic Environment Scotland.

11.7 Registered Parks and Gardens Records within 250m

Parks and gardens assessed to be of particular interest and of special historic interest. The emphasis being on 'designed' landscapes, rather than on planting or botanical importance. Registration is a 'material consideration' in the planning process, meaning that planning authorities must consider the impact of any proposed development on the special character of the landscape. This data is sourced from Historic England, Cadw and Historic Environment Scotland.

Excellent quality agricultural land. Land with no or very minor limitations to agricultural use. A very wide range of agricultural and horticultural crops can be grown and commonly includes top fruit, soft fruit, salad crops and winter harvested vegetables. Yields are high and less variable than on land of lower quality.

Grade 2

Very good quality agricultural land. Land with minor limitations which affect crop yield, cultivations or harvesting. A wide range of agricultural and horticultural crops can usually be grown but on some land in the grade there may be reduced flexibility due to difficulties with the production of the more demanding crops such as winter harvested vegetables and arable root crops. The level of yield is generally high but may be lower or more variable than Grade 1.

13.4 Limestone Pavement Orders Records within 250m

Limestone pavements are outcrops of limestone where the surface has been worn away by natural means over millennia. These rocks have the appearance of paving blocks, hence their name. Not only do they have geological interest, they also provide valuable habitats for wildlife. These habitats are threatened due to their removal for use in gardens and water features. Many limestone pavements have been designated as SSSIs which affords them some protection. In addition, Section 34 of the Wildlife and Countryside Act 1981 gave them additional protection via the creation of Limestone Pavement Orders, which made it a criminal offence to remove any part of the outcrop. The associated Limestone Pavement Priority Habitat is part of the UK Biodiversity Action Plan priority habitat in England. This data is sourced from Natural England.

This data identifies sinkhole information gathered from media reports and Groundsure's own records. This data goes back to 2014 and includes relative accuracy ratings for each event and links to the original data sources. The data is updated on a regular basis and should not be considered a comprehensive catalogue of all sinkhole events. The absence of data in this database does not mean a sinkhole definitely has not occurred during this time. This data is sourced from Groundsure.

This dataset comprises an extract of 1:10,560, 1:10,000, 1:2,500 and 1:1,250 scale historical Ordnance Survey maps held by Groundsure, dating back to the 1840s. It shows shakeholes, deneholes and other 'holes' as noted on these maps. Dene holes are medieval chalk extraction pits, usually comprising a narrow shaft with a number of chambers at the base of the shaft. Shakeholes are an alternative name for suffusion sinkholes, most commonly found in the limestone landscapes of North Yorkshire but also extensively noted around the Brecon Beacons National Park. Not all 'holes' noted on Ordnance Survey mapping will necessarily be present within this dataset.

19.5 National karst database Records within 500m

This is a comprehensive database of national karst information gathered from a wide range of sources. BGS have collected data on five main types of karst feature: Sinkholes, stream links, caves, springs, and incidences of associated damage to buildings, roads, bridges and other engineered works. Since the database was set up in 2002 data covering most of the evaporite karst areas of the UK have now been added, along with data covering about 60% of the Chalk, and 35% of the Carboniferous Limestone outcrops. Many of the classic upland karst areas have yet to be included. Recorded so far are: Over 800 caves, 1300 stream sinks, 5600 springs, 10,000 sinkholes. The database is not yet complete, and not all records have been verified. The absence of data does not mean that karst features are not present at a site. A reliability rating is included with each record. This data is sourced from the British Geological Survey.

The dataset is intended for use at 1:50,000 scale and was derived from both geological assessments and indoor radon measurements (more than 560,000 records). A minimum 50m buffer should be considered when searching the maps, as the smallest detectable feature at this scale is 50m.

21 Soil chemistry 21.1 BGS Estimated Background Soil Chemistry Records within 50m

The estimated values provide the likely background concentration of the potentially harmful elements Arsenic, Cadmium, Chromium, Lead and Nickel in topsoil. The values are estimated primarily from rural topsoil data collected at a sample density of approximately 1 per 2 km2. In areas where rural soil samples are not available, estimation is based on stream sediment data collected from small streams at a sampling density of 1 per 2.5 km2; this is the case for most of Scotland, Wales and southern England. The stream sediment data are converted to soil-equivalent concentrations prior to the estimation. Location

Quantitative Analysis The analysis was carried out using our documented in-house method A006-PL based on HSE Contract Research Report No: 83/1996: Development and Validation of an analytical method to determine the amount of asbestos in soils and loose aggregates (Davies et al, 1996) and HSG 248. Our method includes initial examination of the entire representative sample, then fractionation and detailed analysis of each fraction, with quantification by hand picking and weighing. The limit of detection (reporting limit) of this method is 0.001 %. The method has been validated using samples of at least 100 g, results for samples smaller than this should be interpreted with caution. Both Qualitative and Quantitative Analyses are UKAS accredited. Sample Number

APPENDIX G Hazardous Waste Online Assessment

Waste Classification Report HazWasteOnline™ classifies waste as either hazardous or non-hazardous based on its chemical composition, related legislation and the rules and data defined in the current UK or EU technical guidance (Appendix C) (note that HP 9 Infectious is not assessed). It is the responsibility of the classifier named below to: a) understand the origin of the waste b) select the correct List of Waste code(s) c) confirm that the list of determinands, results and sampling plan are fit for purpose d) select and justify the chosen metal species (Appendix B) e) correctly apply moisture correction and other available corrections f) add the meta data for their user-defined substances (Appendix A) g) check that the classification engine is suitable with respect to the national destination of the waste (Appendix C)

K4MIQ-YGI4T-175DH

To aid the reviewer, the laboratory results, assumptions and justifications managed by the classifier are highlighted in pale yellow.
