They are all at stake when you select an environmental laboratory. Whether It's wastewater

monitoring for MISA compliance, evaluation of hazardous waste, or a full-scale site investigation

you need a lab that you can depend on to provide reliable data, quickly and cost-effectively.

For more than two decades Enviroclean has earned

a reputation for promptness and reliability as a full-service laboratory serving clients both in government and industry. That reputation has been built on a commitment to quality. Our quality assurance program is designed to ensure that every piece of analytical data is

scientifically correct and can stand up to scrutiny.

And we back up that commitment with regular participation in interlaboratory quality assurance programs which test our performance against other labs. We don't claim to be perfect, but when you choose Enviroclean, you can count on getting our best. Always.

I do take umbrage with his statement that I am wrong with my assertion that a major limitation of the technology is lack of understanding of the microbial ecology. Sayler and Fox (1991, Environ.

post consumer plastics Plax Inc.,a producer ofcustom plas tic bottles and closures, announced it soon expects to be commercially producing a new line of containers for Proctor& Gamble Inc. utilizing a minimum of25 percent recycled post consumer plastics. "For the past year, we have been developing a three-layered plastic container to be used for a number of

Procter & Gamble's (P&G) pro ducts," says Andre Levesque, Presi dent of Plax.

His company, which produces more than 200 million containers a

year,recently introduced for P&G a two-layered 400 mL Spic and Span bottle using recycled post-industrial high density polyethylene as the inner layer. "While the middle layer of the new bottle consists of 25 percent post consumer plastics, our target for Proctor & Gamble is at least 50

percent recycled content," says Levesque. "We soon expect to start commer cial production on a 100 percent recycled plastic container for motor oil use. Trials on the container are

currently being done for a major Canadian oil producer."

Industry update Source separated, organlcs composting facility opens In Metro Toronto

Potential spread of Zebra Mussels mapped The Trent-Severn and Rideau systems are the Ontario inland waterways most at risk from an invasion by zebra mus sels, according to a recent MOE report. However, waters in large portions of cottage country are not expected to be significantly affected because they con tain low levels ofcalcium.These include

lakes and rivers in the Parry Sound,Haliburton and Muskoka regions. The Trent-Severn and Rideau water

systems contain the conditions most conducive to zebra mussel infestation,

including elevated pH (low acidity) and calcium levels. As well, these systems contain enough nutrients to support plentiful algae and small zooplankton, which zebra mussels feed on.

The MOE conducted the study using water chemistry information it has ob tained in studying the effects ofacid rain on Ontario waterways. The ministry is acting in an advisory capacity to the Ministry of Natural Resources, which is the lead government agency dealing with the zebra mussel problem. Con centrations are highest in Lake Erie; Lake Ontario is not as hospitable to zebra mussels because of its deep and cold waters. Isolated populations of zebra mussels have been found in other

High densities of HPC bac teria may inhibit the recovery of TC or ganisms and therefore mask the pre sence ofa potential public health threat. They can also lead to taste and odour problems, corrosion and in extreme cases the reduction of hydraulic capa city. Some species of the genera Pseudomonas, Flavobacterium and Aeromonas,

capable of growth in low nutrient envi ronments such as distribution systems, are opportunistic pathogens. For exam ple, the presence ofcytotoxicity(a tissue culture response to bacterial toxins) in strains of Aeromonas in drinking water has been reported, most recently hy Lye and Dufour (1991). In addition a recent epidemiological study in suburban Montreal by Payment (1991a: 1991b)showed a positive associ ation between levels of HPC in drinking water from point-of-use treatment units and the incidence of gastrointestinal ill ness(GI). Of potentially greater impor tance this study revealed that drinking water meeting the current Canadian microbiological guidelines was respon sible for 35% of the reported cases of GI.

In the near future biological treat ment may be a common component of water treatment. In conjunction with conventional treatment it can provide drinking water that is not only microbiologically safe but also essentially free of THMs. When properly applied and monitored this technology also has the potential to reduce levels ofBOM in drinking water. This additional advan tage could lessen the degree of regrowth in distribution systems and thus make it easier for public health officials to iden tify genuine contamination events in a distribution system.In the future regula tory officials may wish to consider the establishment ofguidelines forchlorine residual and BOM in drinking water.

Regulations The improved understanding of at mospheric processes and effects has prompted reformulation of legislation to ensure that air quality concerns are adequately addressed.

Reliable analysis and sampling instrumentation

Now you can get BOD measurements in 3 minutes — with accuracy and reiiabiiity Continuous short-time BOD measurement — accurate results in 3 minutes. AER-O-FLO's BOD M3 is a reliable and robust

analysing instrument for use in sewage works and outfails.

We named the new control and monitoring value BOD M3. Why? Because it reduces the time usually needed for the analysis to 3 minutes. Now our BOD M3 replaces the former BOD measure

ment.* On the standard model the scale range Is from 2 to 5000 mg BOD/L.

This BOD M3 unit works continuously, day and night, 24 hours a day, every day. It delivers mes sages, gives alarms and offers plant control capa bilities, giving operating staff peace of mind aiong with good record keeping.

During continuous short-time BOD measurements the mix ing pumps are controlied by the respiration of the micro organisms. The measured vaiue is calcuiated from the pump ratio. The delay between measuring and printing is approximately 3 minutes.

Computer The mixing pumps together constantly deliver 1000 mi per minute, if the difference in oxygen concentration be tween inlet and outlet probe fails below a preset value, the sewage quantity is increased and the diluting water quan tity reduced, or vice versa when the oxygen difference increases.

Printer

♦ The content of oxygen in the sample flow is measured by the oxygen probe at the inlet and outlet of the circulation

system, if the difference in oxygen concentration deviates from the pre set vaiue, the proportioning pumps are

operated via the computer whereby the nutrient concentration in the reaction

vessel is increased or reduced until the

set value is reached again.

Numerous small plastic rings in a reaction vessel serve as growth surface for the organisms, inside these rings the orga nisms are particularly well protected against mechanical abrasion. A screen prevents the rings from being washed out

^^YiOX super-seal PRELUBRICATED

PIPE GASKET Tomorrows technology is... The lyiox super-seal prelubricated gasket of today. A distinct innovation that becomes the total solution in the

joint sealing of Concrete pipe. Sanitary and Storm sewer systems.

Place the Tylox super-seal around the spigot end of the pipe. The Tylox super-seal should rest firmly against the spigot shoulder. Figure #2.

ADVANTAGES

The Tylox super-seal Is uniquely designed In such a manner that It does

not require any messy or time consuming lubricant application. The Tylox super-seal lubricant Is self contained and not exposed; no special packaging or handling Is required. This Is a distinct advantage as there Is no threat of lubricant deterioration.

FUNCTION

The Tylox super-seal Is automatically Injected with slllcone thus allowing the mantle to roll over the compresslonal area of the gasket causing a water tight seal. The mantle section's final resting area Is between the annular space, therefore reducing extensive sheer forces. See figures #1, #2, #3.

Centre the spigot In the bell and push pipe home. Figure #3

SPECIFICATIONS

The Tylox super-seal Is manufactured from top quality rubber. All gasket material conforms to or exceeds C.S.A. and A.S.T.M.

specifications. Physical properties of the gasket material are available upon request.

The Tylox super-seal Is manufactured for pipe sizes from 12" to 144" In diameter.

HAMILTON KENT

The mantle section of the Tylox super-seal rolls over the compression area of the gasket and comes to rest In the annular space.

Canada's leading manufacturer of molded B extruded pipe gaskets.

show.

CETECH will not only provide show space for environmental exhibits, it will have an on-site conference produced and managed by Environmental Science & Engineering magazine. ES&E now issues a call for papers. We are seeking practical and research papers which will assist industrial firms to deal with complex environmental regulations; deal with process changes which eliminate or reduce environmental impacts; or any new leading edge techno logies which will take Canadian industry into the new demands of the Environmental Age. We invite authors to submit papers for consideration for the two day environmental conference next October. Abstracts and CV's are ap propriate at this point in time. The main criteria are that the papers must be of practical value to firms across Canada from mining to millworking; from chemical production to food manufacturing. Topics could include MISA initiatives legal subjects new technologies and process occupational health hazardous materials manage conversions to reduce environ ment, containment, treatment mental impacts of industry and transportation innovative wastewater pro cesses compliance requirements toxic site responsibilities and stack emissions liabilities

Prince Charles tapped the first of

two Inco Oxygen Flash Furnaces to

officially open the first stage of Inco's major SO, abatement project. The royal visit was the culmination of plaudits and awards for this outstand ing environmental project. The Flash Furnaces were first reported in an ES&E cover story. July 1990. when under construction.

The Prince of Wales is noted for his

outspoken environmental concerns and his visit is a reflection of Inco's efforts to

reduce sulphur dioxide emissions by at least 100 kilotonnes annually some two years earlier than required by regula tion. Both the Ontario and Federal en

vironment ministers have praised In co's initiatives in developing the Flash Furnaces which had won at least two

environmental awards at press time. The total project involves the imple mentation of major technological changes in milling and smelting, de signed to ultimately contain 90 per cent ofthe sulphur in the ore mined and pro cessed in Sudbury.

gitive emissions, and a significant im provement of the smelter workplace environment.

The original total SO,abatement pro ject was estimated in 1988 to cost $500 million. The total capital cost of the re vised project,includingin particularthe unforeseen costs resulting from the in terruption of construction by trade strikes occurring in the spring and sum mer of 1990. and increased materials

and construction costs relating to the rehabilitation of the old smelter build

ing. is now estimated at $600 million. It was expected that the fi rst new Oxygen Flash Furnace would be fully operational by the end of 1991. At that time, one of two existing reverberatory furnaces would be retired and improved smelting productivities and savings realized. Most notably. SOj emissions from the smelter should be reduced by at least 100 kilotonnes peryear from the present regulated maximum of685 kilo tonnes. about two years earlier than required by regulation. Based on the successful commissionings experien

flash furnace and completion of the overall project should be achieved in time to meet the January 1. 1994 Ontario government regulation which stipulates a maximum SOj emission rate of 265 kilotonnes per year. At that rate. 90 per cent of the sulphur in the Sudbury ores will be contained and not emitted.

Beads to clean up spills ImbiberBeads are spherical plastic par ticles that imbibe, or drink in. a broad

spectrum of organic fluids. These im bibing polymers differ from their hy drocarbon-soluble analogs in one im portant respect; they are lightly crosslinked. The cross-links, imparted by a di- or poly-functional monomer, effec tively prevent the polymer chains from separating and going into solution, but do allow the polymer particles to swell in the organic fluid, and. in swelling, to actually imbibe into the polymer net work a quantity of fluid which is depen dent upon the solvent properties of the fluid, the composition of the polymer, and its cross-link density. When the fluid is a "good" solvent, these lightly cross-linked polymer particles will im bibe up to 27 times their original ■ volume,and.in doing so. will swell three and one-half to four times their origi nal diameter.

The polymer particles are solid.There are no pores or voids to fdl as in a sponge. As the beads swell, the fluid actually penetrates the polymer net work. but. in doing so. no large pockets of fluid are formed which might later rupture and leak.The solvent is actually

First, it promotes rapid migration of the fluid throughout the mix.thus insur ing that the beads are more completely contacted by fluid. This allows the most rapid imbibition for a given fluid. Secondly, the wick prevents the indi vidual beads cohering to form a block ing seal which could prevent total utili zation of the imbibing capacity of the polymer.

Decommissioning

ByB. Ibbotson'

Soil Guidelines in Ontario —

are there more questions than answers?

TIhe Ontario Ministry of the

Environment (MOE) policy

document entitled Guidelines

for the Decommissioning and Clean-up of Sites in Ontario outlines a process for decommissioning sites and presents numerical guidelines for22 soil quality parameters. The numerical guidelines contained in the "Guide lines" document are used widely to as sess the need for site clean-up and to determine when clean-up actions are adequate. An early step in evaluating site conditions typically involves a soil sampling program to generate data that can be compared to the MOE guide lines. Non-complying results often are interpreted as cause for clean-up or tak ing other actions to improve the situa

briefly describes the overall philosophy that underlies the guidelines.

At first glance, these two documents may appear to provide clear direction and guidance with respect to soil quality issues in Ontario. Unfortunately,exper ience shows that this is not the case. And

for those unfamiliar with soil quality issues, the situation is compounded by several subtle (though sometimes criti cal) aspects of interpreting the guide lines and MOE policies which constant ly are evolving or emerging. The net result is a situation that confuses those

responsible for evaluating site con ditions or cleaning up sites and undoub tedly is frustrating to MOE staff as well.

This paper describes nine issues that

tion.

In 1991, the MOE issued a second

document entitled Soil Clean-Up Guide lines for Decommissioning of Industrial Lands: Background and Rationalefor De velopment. The "Rationale" document summarizes the information upon which the guidelines are based and

illustrate some of the sources of confu

sion currently surrounding soil guide lines in Ontario. It is hoped that presenting these issues will stimulate debate as to their validity and impor tance and encourage greater efforts to be directed toward resolving these issues.

Issue #1 — in search of the rationale

The types of information considered when setting environmental guidelines and the processes used to interpret that information often are referred to collec

tively as the "rationale". As such, this issue lies at the heart of interpreting and applying soil guidelines. The Rationale document indicates

that the guidelines have been developed by considering the potential for soil contaminants to affect the health of plants, animals, and people adversely. In gen eral, the most conservative (stringent) of these considerations was used to estab

lish the guidelines for residential lands. Aside from these general statements (and a few others discussed in other is sues), the most startling feature of the Rationale document surely is its lack of a description of a rationale. For most parameters, the Rationale document provides little more than a few, point-form comments from the li terature followed by a bare statement of the recommended guidelines. Anti mony is a somewhat extreme example of this lack of detail and rationale. Four sources of information are referenced.

One notes only that antimony is not essential for the health of plants or animals. Another indicates that the mean concentration for soils around the

world is 1 ppm and the range is 0.2 to 10 ppm. The third indicates that some re searchers once recommended that the soil at hazardous waste treatment sites

should not exceed 225 ppm on closure. The fourth source is an MOE report that the "upper limit of normal" in urban soils is 8 ppm. Based on that scant amount of information, the values of

(25 ppm for residential development and (50 ppm for industrial redevelop

ment are recommended as provisional guidelines. No reasons are provided for selecting those specific concentrations.

Larger numbers of references (up wards of 20) are cited for some metals but for other parameters such as oil and grease, electrical conductivity, pH, nit rogen, and sodium absorption ratio, fewer than ten references are offered.

For some parameters, the recommen ded guidelines correspond to concen trations reported in one or more of the references, but for others, the guidelines seem to be chosen arbitrarily or are little

ces that could be contaminants.

Even though provincial guidelines have not been set for specific organic compounds, many site investigations in Ontario now include analysis of soil samples for numerous organic com pounds (often at the suggestion of the MOE). This has put pressure on the MOE for the last few years to develop guidelines for those types ofparameters. While efforts apparently are underway to develop provincial guidelines for some organic compounds,the timetable for this work and the compounds being considered have not been made public. Establishing guidelines for a few pa rameters at a time likely will not be what proponents or MOE staff need to ad dress this issue. In the long-term, it may be more useful for the MOE to describe

the process it would prefer to be used to set soil guidelines. The description would identify the types of information that should be considered,the ways that

specific types of information should be interpreted,and the relative importance ofeach type ofinformation when setting criteria.

Furthermore,the interim soil guidelines for PCBs and dioxins and furans were recommended by the Hazardous Con taminants Coordination Branch.Depending on the types of contaminants of concern and the location of a specific site,

other agencies that may contribute to setting site-specific guidelines can include the Ministry of Labour and regional or municipal medical officers of health.

and guidelines In addition to soil guidelines,the MOE also recommends

standards,guidelines,criteria, and objectives for other envi ronmental compartments (or media) including air and water. Historically, guideline setting for each compartment has been done with little regard for the others; however,for several years the MOE has been advocating the use of multi media approaches for assessing environmental conditions and developing guidelines. To date, this does not appear to have been done with the provincial soil guidelines. Further more,it is likely that there are incompatibilities between soil guidelines and other types of guidelines.

The multi-media approach requires that a holistic view be taken ofcontaminants in the environment.For example,the

process of determining soil guidelines also should give con sideration to the possibility of adverse effects occurring in the other media. In the case of a person living at a site with contaminated soil, consideration should be given to the

combined effects of potential exposure via numerous path ways such as direct ingestion ofsoil or dust particles,inhala tion of vapours or dust particles, ingestion of local ground water, ingestion of locally-grown plants, and dermal contact.

But those practices make inefficient use of a precious resource (capacity at landfills and disposal sites) and merely shift po tential problems posed by contaminated soils to other locations rather than try ing to remediate and reuse local soils.

entire approach to setting soil quality guidelines. In the short-term, the latter option could cause even more confu sion and frustration than is currently experienced; however, would this be worse than to chose the former? In my opinion,the existing guidelines and po licies lack a defensible rationale and

pose more questions than they answer. Worse yet. merely accepting the existing situation may lead to clean-up efforts of questionable benefit.

Undeniably, there already is a great need for soil quality guidelines and a sound rationale, but the situation will

only be more critical next year or the year after that. Clearly, now is the time to rethink this entire issue and to establish

an approach based on firm scientific principles. If it chooses to do so. the MOE would be well-served to follow the

advice it provides in the Guidelines document and invite other stakeholders

ject. Our enthusiasm might be ques tioned, especially as other municipali ties were less eager to be involved. In the mid eighties we had become aware that sewer use control had become reactive

to problems.The planned management of industrial discharges to our sewers was a secondary consideration at this time.

Since adoption in 1979 by our Muni cipality of a by-law based on the 1975 Ministry of the Environment/Munici pal Engineers Association(MOE/MEA) model,only three charges had been laid. These relatively few charges may have been interpreted as reluctance by our Region to pursue litigation rather than the status of industrial compliance. By 1986, an increased sensitivity on the part of the general public to the abuse ofour environment plus an Envi ronment Ministry that had become more aggressive with regard to munici pal violations,forced a re-assessment of our commitment to sewer use control.

In the same year, the Ontario Gov ernment published a policy and pro gram statement of its intentions to con trol municipal and industrial discharges to surface waters, MISA, (Municipal-Industrial Strategy for Abatement).

Development of a local program in isolation or alignment with the Provin cial initiative were the two choices avail able to us. We chose to work with the

latter,to better protect our municipality's interests. In early 1989, as the first step, our Council passed a new sewer use by law based on the 1988 MOE/MEA model.

This new by-law was an improved control instrument over our previous version. The Agreements Section had a new and valuable feature which dealt

with compliance agreements. This ag reement formalized, in a legal docu ment, both the process and time frame that would be followed by an industry to achieve compliance, without com promising future enforcement actions. This was an essential tool to gain stricter control over industrial discharges to

Should a company wish to perform daily flow proportional sampling on the subject parameters, with verification by our of fice, a last quarter adjustment is then made to reflect actual loadings.

two areas covered under the program, industrial sampling and enforcement. INDUSTRIAL SAMPLING

Specific mention is being made of sampling since it represents one of the costlier aspects of the program for a municipality. Sampling includes col lecting representative samples with sub sequent analysis for the required parameters. To arrive at the number of industries

to be sampled, the 1988 Model By-law sets out a schedule based on flow for

"major industrial dischargers". While saying every "major industrial dis charger" should be sampled at least once a year,some as frequently as once a month, the concise definition of "ma

jor" is lacking. The MOE's discussion paper "Con trolling Industrial Discharges to Sewers — Sept/88" sets out criteria for estab lishing those industries that will be sub ject to sampling and municipal audit sampling.

tries under the program to 400 with 450 points of discharge as some industries have more than one point of discharge. The collection cost for these samples would be $157,500.00 and analyses a fur ther $225,000.00 for a total of $382,500.00. In addition to the deter

We propose that unless the serious ness of the violation requires it, all first violations are dealt with through a "No tice of Violation". A second violation

Vancouver embarks on $600 million wastewater project

Today the GVRD sewerage and

areas: Vancouver. North Shore. Lulu

Island,and Fraser. Each ofthe sewerage areas is served by a primary treatment plant. The Vancouver sewerage area, en

compassing about 500.000 persons, is served by the lona Island treatment plant. The plant discharges to Georgia Strait via an eight kilometre long deep sea outfall.

The North Shore sewerage area, with a population of about 150.000 persons, consists of the municipalities on the north side of Burrard Inlet. Wastewater

treatment is provided by the Lions Gate plant which discharges effluent to Bur rard Inlet near the Lions Gate Bridge. The Lulu Island sewerage area serves the area of western Richmond,south of

the City of Vancouver. The wastewater flow from about 100.000 persons is treated at the Lulu Island treatment

plant. Effluent is discharged to the Fraser River near the mouth.

The Fraser sewerage area is the larg est sewerage area with a contributory population of over 600.000 persons.The sewerage area consists of the municipa lities in the eastern area of the region with treatment provided at the Annacis Island treatment plant. This plant dis charges effluent into the Fraser River approximately eighteen kilometres up stream from the mouth.

Collecting flow proportional samples has never been easier.

SIGMA's new Streamline" subcompact and standard sized samplers are flowmeters too: generate reports via hand-held interrogator Until now, monitoring flow and collecting flow proportional samples required two units â&#x20AC;&#x201D; a sampler and a flowmeter. Not any more. Streamline puts the flowmeter inside its new subcompact sampler: an easy-to-carry unit with room to spare in

tight manholes. And only Streamline can handle the full range of sampling applications. One controller fits a subcompact and a standard sized base with nine composite and multiple bottle choices.

The new Streamline stores the time and date samples are taken, plus daily flow minimums, maximums and averages; total flow, cumulative average, cumulative total and flow chart. The RS232D serial interface allows data transfer to a laptop or hand-held interrogator. The interrogator can hold data from up to 9 samplers and interfaces with any IBM compatible PC or dot matrix printer for sampling/flow reports. Streamline's Delta C Liquid Sensing System is self-adjusting and nonfouling, eliminating sample volume calibration and guaranteeing repeatability independent of varying heads at the intake. Streamline starts watertight; stays watertight: electro mechanical components are sealed in a NEMA 4X 6 housing and both keypad and display are protected by a waterproof polyester membrane. There's a lot more to learn about Streamline. Call 1-800-

Streamline Controller can be used with either the subcompact or standard sized base, allowing one unit to handle the full range of sampling applications. Streamline offers nine composite and multiple bottle choices.
