EDITORIAL COMMENT BY STEVE DAVEY

Quiet flows the now not so dirty Don

he February 1st edition of the Toronto Star newspaper reported on a milestone event in the decades long $1.354 billion Port Lands Flood Protection Project, which is part of Toronto’s Don River rehabilitation project. Reading it made me recall a January 1970 article written by ES&E Magazine’s co-founder Tom Davey, who was editor of Water & Pollution Control Magazine (W&PC) at the time. (Tom and I would later work together editorially on W&PC Magazine from 1982 to 1986, but that is another story). In his article, entitled “Quiet flows the dirty Don”, about Pollution Probe staging a mock funeral for the Don River, Tom reported that the funeral procession wound its way along the river to the mournful strains of Chopin’s funeral march. Earlier a 100-car cavalcade, including a hearse, had driven from the University of Toronto (U of T) to the east bank of the river, just north of the Prince Edward Viaduct (Bloor Street). Then, dressed in period costumes, which reflected a bygone era when the river was pure, members of Pollution Probe held a mock service to dramatize the death of the Don. This mock funeral was attended by the Reverend James Cunningham, Chaplain of the U of T’s Hart House. Toasting the future of the Don with a cup of pure water, he predicted that the younger generation’s concern about pollution would lead to the restoration of rivers like the Don. It is heartwarming to know now that the Reverend’s optimism about the future of the Don River was not in vain. In the 1980s, a citizens group launched the Task Force to Bring Back the Don in 1989. One of their first projects was to create a book called Bringing Back the Don.

6 | February 2024

Published in 1991 by the City of Toronto, the book sketched a vision for how the river could be revived. Plans to revitalize the mouth of the Don River and protect the surrounding area from flooding became formally known as the Don Mouth Naturalization and Port Lands Flood Protection Project, a name that was later shortened to the Port Lands Flood Protection Project. For over a decade now, work has been done to reroute the Don, clean polluted soil, create new parks and flood-proof the area to unlock a swath of land, including the old Unilever plant site, for redevelopment. As reported in the aforementioned Toronto Star article, “one of North America’s largest infrastructure projects in the Port Lands includes the long-awaited naturalization of the mouth of the Don River, with a goal to reconnect it to Lake Ontario. The new river valley will be filled from the west end, drawing water from Lake Ontario through the Polson Slip.” As of February 1, pumps will deliver 300 cubic metres of water an

hour everyday, 24/7, until the water reaches a depth of about two to three metres. The natural landscape of the 700acre river valley will become home to diverse plants and wildlife. With the threat of flooding removed, development can now begin on new places to live, work and play in the Port Lands. The approved Villiers Island Precinct Plan will guide development of a new mixed-use community. However, poor water quality still plagues the Don River. In the Toronto and Region Conservation Authority’s (TRCA) most recent water quality report card, the most heavily urbanized portion of it scored an “F” for its elevated levels of phosphorus, nutrients, chlorides, salt and e coli. A significant source of these pollutants are the numerous combined sewers, which discharge storm runoff with raw sewage into the Don during significant rain events. To counter this, the city is spending $3 billion over 15 years to build three tunnels that will route untreated sewage away from the river, which will end such sewer overflows. I am sure that the founders of Pollution Probe would be pleased to know that their efforts to bring attention to the polluted Don River began a 50-year process to revitalize it.

8 | February 2024

everal First Nations chiefs have announced that they look forward to providing committee testimony to refine a new safe drinking water and wastewater bill introduced in the House of Commons. Atlantic leaders such as Chief Bob Gloade expressed support for Bill C-61 and the opportunity to finally have a detailed framework to guide processes around First Nations water infrastructure. “The proposed legislation is a great start and a unique opportunity for First Nations to take control of a service critical to the social, economic, and environmental well-being of our communities,” announced Chief Gloade, who is also Co-Chair of the Atlantic Policy Congress of First Nations Chiefs Secretariat.

vices, Patty Hajdu, introduced the bill on December 11, 2023, more than a year after the government repealed the 2013 Safe Drinking Water for First Nations Act, which was heavily criticized by many Indigenous communities. Hajdu explained that Bill C-61 would affirm the inherent right of First Nations to self-government, and hold the federal government accountable to continued funding investments in water infrastructure. The draft bill states that First Nations persons must receive water services comparable to those received by persons in non-Indigenous communities. “Created with First Nations, this legislation is the foundation of clean and safe drinking water for generations to come,” Hajdu announced when tabling the bill. She said that it establishes the rights and supports that should have always been there for First Nations. Also that it creates the tools First Nations need to manage their water systems and ensure the water they draw from is safe. Hajdu said the legislation is also expected to lead to the application of minimum standards for clean drinking water in every First Nation, and lay the groundwork for the creation of a First Nations-led water commission to support communities. The draft bill states that the commission could, in part, be responsible for “providing advice to First Nations in relation to drinking water and wastewater, including by obtaining legal advice and coordinating its provision to First Nations.” The new legislation, called the First Nations Clean Water Act, was also part of the terms of the $8 billion drinking water

Study reveals effectiveness of replicating beaver dams for flood mitigation By ES&E Staff

recent study reveals data from 105 man-made “leaky barriers” that mimic the logs-andbranches-style engineering of dams constructed by beavers. Researchers want to understand how effectively the barriers operate when exposed to flood waters, and whether communities could benefit from them. Led by scientists from Cardiff University in Wales, and the University of Worcester in England, the study analyzed the effectiveness of the nature-inspired barriers, which greatly slows but does not completely stop streamflow. Previously, scientists have only used numerical modelling based on multiple assumptions to measure the impact of these barriers. Now, researchers were able to monitor the barriers over a distance of about five kilometres with pressure transducers, rain gauges, flow meters, and drone-based photogrammetry. The engineered leaky barriers, which sometimes had logs secured to the 10 | February 2024

University environmental scientist and study co-author, in a statement about the study. “This tells us that they are a valuable addition to existing flood management strategies. Not only that, but leaky barriers also offer a low-cost solution and are a sustainable flood defense which increases biodiversity in our rivers and on nearby land.” Wilson added that the study’s findings can be used by government and industry to develop flood defences for smaller, more frequent storms, and help create an approach for modelling leaky barriers for large storms. Ian Maddock, professor of river science at the University of Worcester, and one of the study’s co-authors, said that the results of the study have helped to inform work with local authorities who want to identify new sites for natural flood management. “It’s enabled us to target sites where the installation of leaky barriers will have the greatest impact in reducing flood risk to communities and landowners downstream,” Maddock said in a statement. In particular, the study’s findings indicate that to maximize the magnitude of backwater rise, leaky barriers should have a large vertical extent and be located in deeper, confined cross-sections along a stream reach. The U.K. Department for Environment, Food, and Rural Affairs (DEFRA) has been funding the investigation of similar flood protection research. It has implemented some 4,500 green infrastructure measures nationwide, providing approximately 1.6 million m3 of additional stormwater storage space. In early 2023, the Canadian Standards Association released a report designed to help governments shift from traditional grey or engineered infrastructure, such as walls and dikes, to nature-based solutions like restoring forests and wetlands, to manage flooding and erosion. One of the largest beaver dams in the world is located in northeastern Alberta’s Wood Buffalo National Park. The front of it runs approximately 775 metres in length and the entire perimeter is close to 2,000 metres.

banks with wooden pegs or rebar, controlled flooding behind the barriers and created temporary pools of water, says the study recently published in the Journal of Hydrology. The barriers were able to store enough water to fill at least four Olympic-sized swimming pools during some 15 storms. This prompted researchers to want to further understand the feasibility of communities implementing such low-cost, soft-engineering solutions. During the study, researchers recorded raised water levels up to 0.8 metres at each barrier. These areas took between seven to nine days to return to normal, and could protect communities from flooding downstream. Spacing between barriers varied from 11 to 50 metres, while the vertical gap below the barriers varied between zero to 0.75 metres. “Leaky barriers are most effective in narrow channels with steep banks and better at reducing flooding during smaller storm events than during larger For more information, email: ones,” said Catherine Wilson, Cardiff editor@esemag.com

WWTP upgrade will help Orangeville reach GHG target By ES&E Staff

he Ontario Town of Orangeville recently announced a series of upgrades to its water pollution control plant that local officials say will improve performance and reduce emissions. In 2021, town council adopted an emissions reduction target of net-zero greenhouse gases by 2050, so the plant’s rehabilitation project will explore opportunities for energy recovery from the wastewater treatment process, local officials announced, as the plant accounts for a significant portion of Orangeville’s emissions. “For example, the design of the roof replacement on the digester that uses anaerobic digestion to treat solids. The anaerobic digestion creates an environmentally-friendly renewable fuel called biogas,” explained Tim Kocialek, Orangeville’s general manager of Infrastructure Services, in a statement. “We’ll be exploring how this biogas could be used for on-site energy recovery.” The water pollution control plant consists of an old and new

portion for separate extended aeration facilities. Both sections treat wastewater generated by approximately 11,300 households within town limits. The plant is an activated sludge plant with a Modified Ludzack-Ettinger (MLE) denitrification process, effluent filtration, chlorine disinfection, and dechlorination. Kocialek said that a plant shutdown will be required to perform work on the detritor grit removal system and clarifier #3, but will not impact how wastewater is processed for the community. Work that requires any systems to be shut down will be completed during the summer, when low flow conditions occur, mitigating any impact to services, he said. The detritor system, explained Kocialek, removes grit-like sand, fine gravel, and other solids from the raw sewage, while clarifier #3 removes particles and solids from liquid. “Both systems were built as part of the upgrade and facility expansion in 1974,” he said. “Once the project is complete, the upgrades and changes will increase performance, capacity, and efficiency, improve the lifespan of different buildings, and lower maintenance and operating costs related to heat loss.” Planned updates include: • Replacement of secondary clarifier #3. • Upgrades and replacements in digester #2. • Replacement of two heat exchangers. • Structural rehabilitation of the detritor, digestor #2, and the secondary clarifier #3. • Replacement of the digester building complex roof. • Electrical, instrumentation, and control upgrades related to equipment. In recent years, Orangeville completed a series of upgrades at the new portion of the plant with engineering and environmental consulting company R.J. Burnside. Part of the work expanded the facility’s average capacity from 14,000 m³/day to 17,500 m³/day.

PFAS

Tests show surfactant-based technology effective in removing PFAS from soil and groundwater By George (Bud) Ivey, David Holmes, and Cecilia MacLeod

n recent years, several major corporations, including 3M, DuPont, and Chemours (a DuPont spinoff), have reached major settlements with municipal governments and other plaintiffs, agreeing to spend billions of dollars to remove PFAS from their production processes, products and the environment. A substantial amount of these settlement funds will go towards helping water treatment facilities to remove PFAS from drinking-water supplies. But significant dollars will also have to be spent to remediate PFAS-contaminated soil, bedrock, and groundwater. The potential markets for PFAS remediation are numerous, ranging from chemical and other product manufacturing to electric power, wastewater treatment, real estate development, retail petroleum, landfill operations, mining, ports and harbours, federal facilities, and more (Environmental Business Journal, Vol. XXXII, No. 5/6, 2019). All face significant future liabilities as the regulatory net and public awareness around PFAS grows and tightens. However, remediation contractors can face these future liabilities as well if their PFAS cleanup solutions prove inadequate to the task. The traditional pump-and-treat solution has been applied to the remediation of PFAS-impacted groundwater, but it is expensive and can take decades to achieve any significant levels of removal. Additionally, contamination in the more mobile, high-permeability groundwater zone can migrate into immobile, low-permeability subsurface zones, and pump-and-treat is not effective in removing contamination from those low-permeability zones. This can lead to future releases and back-diffusion into the high-permeability zone, and thereby failure to meet regulatory standards. Some chemical and biological removal methods are being tested, but satisfactory results have not emerged. Methanol solvent extraction is used in laboratory soil extraction, and some small-scale testing. However, regulators are not likely to look approvingly at injecting many of these impactful chemicals into the ground. One potential solution, however, has been shown to be effective in recently completed tests. Ivey International Inc. (IVEY) has developed a new formulation from its Ivey-sol surfactant enhanced remediation (SER) technology to address PFAS contamination in groundwater, soil, and bedrock regimes. Tests of the PFAS-SOL formulation conducted in the United Kingdom (UK) in collaboration with the University of Greenwich, with analysis by ALS, have shown significant PFAS mass

removal rates. This formulation is non-toxic, biodegradable, and pH neutral. It is based on non-ionic formulations, with a novel additive, that can selectively desorb contaminants and render sorbed, globular and non-aqueous phase liquids (NAPL) soluble in the aqueous phase. This means it forms a non-emulsified mixture with water and can thus be more easily controlled and removed from impacted soil, fractured bedrock, groundwater, and surface water while maintaining plume control. The PFAS-SOL surfactant structure consists of a hydrophilic head and a hydrophobic tail. The hydrophobic tail is by design, selectively attracted to the organic functional groupings on target contaminant molecules, while the hydrophilic head is attracted to groundwater. Based on this modulated structure, these surfactants offer multiple properties that improve the effectiveness of most continued overleaf…

PFAS remediation strategies, predominantly by overcoming the limitations associated with contaminant sorption and low solubility. In addition, they lower the relative surface tension of water and overcome interfacial tension, thereby improving its wetting and associated hydraulic properties across broader soil textures. PFAS-SOL can selectively remove PFAS from sorbed soil and bedrock surfaces, from globule and/or NAPL phase-partitioned layers, to make them more available for enhanced physical, biological, and/or chemical remediation. For the column tests, one metre by 14 centimetre diameter columns were filled with a mineral sand (a building sand), with 10% activated carbon to act like natural organic carbon absorptive content within the soil. The columns were then slowly saturated with water from the base and drained to a set volume. They were next spiked with 250 mg each of PFOA and PFOS to mimic a PFAS source zone and then drained and filled, with the effluent sampled to show contaminant recovery in water. The columns were filled again, one with methanol at a 50% concentration in water, the other with the PFAS-SOL surfactant formation at a 4% concentration. They were then drained, with the increased concentration in the effluent in the PFAS-SOL column showing a large increase in PFAS concentration. The columns were then slowly taken

apart to deliver a moisture profile and obtain soil samples to measure retained PFAS. The results showed significant mass PFAS removal from the PFAS-SOL flushes. Flushes with water alone yielded PFAS recovery of approximately 5 micrograms per litre (μg/L), whereas surfactant flushes exhibited improved recovery of up to 30.45 micrograms per litre (μg/L). This meant an average improvement in PFAS removal of 240%, with concentration spikes of up to 622%. PFOA recovery averaged 160%, with best results of 185%. PFOS recovery averaged 297%, with best results of 732%. Total PFAS recovery averaged 242%, with best results of 622%. Subsequent tests have shown similarly impressive results, suggesting a bright future for this surfactant-based PFAS remediation compared with other methods that are time-consuming and costly, and don’t provide assurances against future back-diffusion risks liability associated with new technologies.

CYBERSECURITY

Security agencies warn of hacks into Israeli-made logic controllers By ES&E Staff

group of U.S. agencies has issued a joint statement warning of recent cyberattacks by an Iranian military organization “actively targeting and compromising” Israeli-made Unitronics Vision Series programmable logic controllers (PLCs) commonly used in water and wastewater systems. The Municipal Water Authority of Aliquippa, Pennsylvania, recently shared a photograph of a hacked human-machine interface from a compromised Unitronics programmable logic controller at a pump boosting station. The screen displayed the hacker’s electronic calling card: “Every equipment made in Israel is Cyber Av3ngers legal target.” The authority reported the hackers were able to gain control of the remote booster station that monitors and regulates pressure for two townships, but stressed there is no known risk to the drinking water or water supply. A joint statement from the Federal Bureau of Investigation, the Cybersecurity and Infrastructure Security Agency (CISA), the National Security Agency (NSA), the Environmental Protection Agency (EPA), and the Israel National Cyber Directorate, suggested there have been several PLC hacking victims targeted across multiple U.S. states. The authorities linked the cyberattacks to the Iranian Government Islamic Revolutionary Guard Corps. “The PLCs may be rebranded and appear as different manufacturers and companies,” the joint statement warned. In a statement following the Aliquippa hack, the Canadian Centre for Cyber Security also issued an alert about the potential exploitation of Unitronics PLCs. Sami Khoury, head of the Canadian Centre for Cyber Security, issued a statement on Twitter, however, which suggested that “the risk to industrial control systems accessible from the Internet is not limited to Unitronics devices or the water and wastewater systems sector.” Khoury added that, “connecting industrial control systems directly to the internet without appropriate security controls is a huge risk.” The U.S.-based non-profit Water Information Sharing & Analysis Center, better known as WaterISAC, issued an advisory and guidance to water utilities following the Aliquippa hacking incident. Echoing the security protocols suggested by the authority agencies in terms of increased password protection, WaterISAC went further in its recommendations for safe use of Unitronics devices. It advised utilities to utilize a TCP port other than the default port TCP 20256. Additionally, users are advised to update the device’s PLC/HMI to the latest version provided www.esemag.com @ESEMAG

by Unitronics, and implement a firewall or VPN in front of the programmable logic controller to control network access to the remote system. WaterISAC stated that Cyber Av3ngers claims to be an active group focused on targeting Israeli water and energy sites, including 10 water treatment stations in Israel, according to their Twitter (X) page.

WATER

Burlington pumping station commissioned after successfully navigating supply chain delays By Anna Comerton

alton Region is a growing municipality in southwestern Ontario with a population of approximately 600,000. It provides drinking water to residents and businesses, and maintains an active program to continuously improve its system. The Bailie Booster Pumping Station and Reservoir supply water to the Burlington area. As part of its asset management program, Halton Region retained Associated Engineering (AE) to upgrade and rehabilitate the pump station and reservoir. The pumping station upgrades include replacing the plumbing, heating, ventilation, and air conditioning systems, booster pumps and piping/valving, chlorine storage and dosing system, motor control centre, standby power and electrical systems, instrumentation and SCADA system. Structural rehabilitation was also required. The two-celled, underground concrete reservoir has a storage capacity of 17.5 million litres. Its top is grassed, creating a park-like setting. Structural rehabilitation of the reservoir involved removing the existing grass surface and waterproofing system and installing a new hot applied rubberized asphalt waterproofing membrane system on the reservoir roof slabs. After membrane replacement, landscaping over the roof was reinstated. The main goal of the waterproofing replacement was to update the reservoir to meet new potable water storage guidelines and minimize the risk of contaminant infiltration. Site drainage design and sizing of the reservoir subdrain system considered climate change and anticipated increased frequency of and heavier precipitation events. More extreme seasonal temperatures and an increase in relative humidity were considered in the design of the pump station heating, ventilation, and air conditioning system. All process piping was insulated to address an expected increase in humidity. These upgrades to the pumping station had to be staged to allow continued operation of the station, as it is an integral part of the Burlington water supply system and could not be taken out of service for an extended period. Interruption or reduction of service was performed during low demand season to accommodate overall distribution system needs. Careful planning and communication with all stakeholders were required, so that individual equipment was replaced and commissioned in a phased manner to minimize any impact on operations. For example, one booster pump and its associated piping/valving system was replaced at a time. Similarly, replacing the main reservoir fill/draw header was done in sections so that the period required for station shutdown was minimized (e.g., less than 24 hours) and occurred 20 | February 2024

during low demand season when an alternate station could handle the demand. Residences surround the project site on three sides in this quiet neighbourhood. Construction was planned to restrict working hours, mitigate noise and dust, identify location of soil stockpiling, provide privacy screening, limit the number and location of construction vehicles, and prohibit idling trucks on residential streets. The Region also had a project ambassador assisting with communicating updates to the community and addressing questions. AE completed the preliminary and detailed design and tendering for the project, along with the required approvals and permits. The project was tendered in July 2020 and the general construction contract was awarded in November 2020. Adding to the scheduling and work-phasing challenges were supply chain delays due to the global pandemic that delayed delivery of the booster pumps by nine months. In collaboration with Region operations and the contractor, AE developed a plan to commission the pumps and ancillary system individually as they were delivered. After navigating significant delays in delivery of the new pumps and other major equipment, the upgrades to the Bailie Booster Pumping Station were commissioned in August 2023.

Moncton upgrades the fire protection system at its water treatment facility By John Sheehan and Matthew Quick

hen a fire breaks out at a critical infrastructure facility, its impact can stretch well beyond the building occupants. In fact, it can potentially disrupt tens of thousands of lives. So, when it came time for the City of Moncton, New Brunswick, to upgrade the fire protection system at its water treatment facility, a solution was needed to keep the plant operational in the event of an emergency. Tweedie & Associates Consulting Engineers, the project’s engineer, was tasked with specifying a system to protect the facility’s chemical room, electrical room and diesel backup power generator. Traditional sprinklers would potentially damage controls and critical electrical equipment. “We started to explore alternative methods, with the understanding that this project needed an environmentally-friendly, cost-effective solution,” said Tweedie Principal Stephen Tweedie. The Victaulic Vortex System™ discharges a dual agent of water and nitrogen to extinguish fires. The technology’s patented hybrid emitter creates sub

“If the water treatment facility goes offline, residents are left without water. The Vortex system will help prevent shutdowns when there are fires and allow the plant to get back to normal operation quickly,” Tweedie said. “The system can also run on battery power for 48 hours, which made it appealing to us for this specific application. Even if the facility experiences a power outage, the fire protection system will function as needed, and the city will still be able to deliver water to its residents.” Other chemical fire suppression products on the market use PFAS substances that can concentrate in a water supply and affect its quality. The Vortex system uses 100% green, non-toxic agents to extinguish fires. This design prevents environmental contamination and ensures no trace of chemicals in the air so the space maintains safe breathing levels, helping ensure employee safety and minimize downtime.

It’s also important to consider the data that was used to develop any existing structures to determine if redesign or replacement is needed, based on current storm data and future projections. CALIBRATION OF DATA

Calibration of data typically refers to matching the same situations repeatedly to get the same results, or the process of adjusting parameters to confirm the model will output accurate data, based on input parameters, and match empirical data as closely as possible. Calibration data can take several forms, using calibration solutions to readjust instruments for additional field measurements to add more data points. The purpose of calibration is to ensure that the data being utilized collates as closely to the real world as possible. This can be a very simple process for the mechanical calibration of equipment, or could require hundreds of additional data points to check datum against. Calibration of data points can be very challenging, as identical simulations or situations are needed to properly compare them to one another. Calibration of any data or field instrument is vital to ensure data accuracy. Without calibration of equipment, the data collected will not be accurate and decisions made using the data will suffer. Likewise, uncalibrated data can mislead decision-makers and cost money to make corrections later on.

first starting with topographic maps to try and determine the watershed boundaries. These can then be divided into sub-basins as runoff characteristics are identified and applied to the data. There are key questions to ask during data analysis: • Is the data time-dependent, such as a storm gauge? • Is it a static or dynamic reading? • Is it recurring data?

• Can recurring data be parsed into smaller pieces? • What were the field and weather conditions? • Which areas need the most/least attention? • Are you dealing with historical data vs. current data? No matter how much data you have or continued on page 67

POTENTIAL PITFALLS OF DATA

The drive towards automation and advancement in low-cost sensor technology has many organizations overwhelmed with data and not knowing where to start. More data has been collected in the last several years than in all of previous human history. Knowing where to start and how to proceed are the hardest parts of data management. Some basic rules of thumb are to understand the overall picture of the system of data you have collected. Is it a watershed? A distribution system? What is it, first and foremost? Then try and choose a logical starting point from your understanding of the objective. If it’s a watershed, maybe start at a sample location furthest away and work across it.

Emergency water reservoir refill needed for Kangiqsualujjuaq, Nunavik River Region, Northern Quebec By Chris Keung, Ken Johnson, Luc Malo, Alfred Tsui, and Hossein Shafeghati

angiqsualujjuaq, formerly known as George River, is a remote Inuit village in the Nunavik Region of northern Quebec, located 1,500 kilometres north of Montreal at 59 degrees north latitude. The community is located at the mouth of the George River on the east coast of Ungava Bay in Arctic Canada and has a population of approximately 1,000 people. Kangiqsualujjuaq is Inuktitut for “the very large bay”. The community is only accessible year-round by air, and by sealift from Montreal during the limited ice-free period from late July through October. Kangiqsualujjuaq’s current water source is an elevated water supply lake north of the community, referred to as Imirtaviup Tasinga Lake. The lake has a capacity of 360,000 cubic metres at an elevation of approximately 140 metres above sea level. Raw water is conveyed from the lake by gravity approximately 1,900 metres to the existing water treatment plant. The water supply is a two-pipe system consisting of a main water supply pipeline and a recirculation line. The recirculation line provides freeze protection to the water supply line via kinetic energy generated by continuously recirculating flow from the water treatment plant to the lake. In the early summer of 2023, following the snow melt, the community operating staff observed a significant leak from the buried water recirculation pipe from the raw water lake to the water treatment plant. The break in the line was not discovered earlier in the winter, as the leak was not apparent beneath the snow cover. Upon further investigation, it was discovered that the break caused an unexpected draining of the lake. It was determined that a refill was necessary to provide enough water supply to the com26 | February 2024

of cold temperatures in October. After the consideration of several water sources in reasonable proximity to the lake reservoir, Ellasie Lake was selected as the most appropriate source for the refill. It is 1,400 metres north of Imirtaviup Tasinga Lake. Following the source decision, all efforts focused on the logistics for executing the refill, which was up against the coming Arctic winter, where October temperatures can fall to -10°C. The refill from Ellasie Lake required a pumping system and a 1,400-metre overland piping system that would have to be mobilized by air. The community is not accessible by road and as the project progressed at the end of the summer, the sealift was not an option. In addition, the community airfield is not long enough to land larger aircraft. Given the mobilization requirements and limited time for on-site construction, a pumping system comprised of flexible piping and diesel pumps was selected as the most appropriate design. Based on the project timelines, the pumping operation was assumed to take place over 30 days (24/7 operation). This required a pumping system with a flow rate of approximately 40 litres per second, while providing a static lift to overcome approximately 65 metres of static head. Various equipment suppliers were contacted to find equipment that was readily available and could be procured and transported given the numerous logistical challenges. This included sourcing flexible hosing that was both durable enough to withstand the pressure requirements, and light enough to be installed and handled by a local crew to minimize on-site construction efforts. Following this exercise, two high-head pumps, 1,400 metres of flexible 200-millimetre hose and associated materials were procured and specially modified to meet the strict dimensional requirements of the cargo aircraft. Discussions occurred with various cargo and logistic companies to organize transportation options for the equipment. The weight and dimensions of the diesel pumps were close to all the limitations of available aircrafts and pushed the logistics crew to be creative. As the 28 | February 2024

final solution, a plane was chartered from Montreal to the nearby community of Kuujjuaq, which has a longer airfield and could land a larger Boeing 737 aircraft. From Kuujjuaq, the equipment and materials were transferred to a locally-hired fishing boat and transported the remaining 200 km to Kangiqsualujjuaq. Once the equipment was on site, the main challenge was to install the flexible pipe along a hastily-constructed trail from Ellasie Lake to the raw water lake. Appropriate selection for the flexible hose allowed construction crews to transport, lay and install the coupling connections with locally available equipment and in a timely manner. Other site works included the construction of a pad for the pumps, installation of a temporary intake, installation

of a fuel tank and 24,000-litre fuel supply and maintenance and operation of the pumps during the refill. Pumping began in late September 2023 and the refill was successfully completed 35 days later.

Creating a safe and reliable water and wastewater infrastructure system for Fort McMurray 468 First Nation By Andrea de Vries

uilding cultural, economic, and environmental sustainability is foundational to any community, and the Fort McMurray 468 First Nation (FMFN) wanted to build a future that would serve community members for generations to come. In the early 2010s, FMFN undertook a series of community engagement and planning exercises to help them document and articulate their membership’s vision for the future. In 2013, they completed a Community Comprehensive Plan followed by an Economic Sustainability Master Plan (ESMP). After a year-long participatory process of data collection, research, site visits, surveys, and community engagement, the ESMP team produced a shortlist of conceptual plans for opportunities that would manifest FMFN’s vision for a vibrant future. The shortlist featured several opportunities ranging from community health and wellness centres to new commercial opportunities. Yet each of these opportunities was dependent on the final initiative on the list: reliable and safe water and wastewater infrastructure. Prior to 2023, FMFN’s water and sewage servicing was provided through an aging truck haul system. Every serviced building was constructed with both a water and a wastewater tank, and trucks would frequently fill and empty these tanks. Although well intended, the truck haul system had some quality of life drawbacks. It could be unreliable, had capacity limitations, and increased health and environmental risks due to extensive handling requirements. It was also a pervasive source of noise and smells in the community. Without a modernized system, opportunities to manifest FMFN’s vision would remain limited. So, FMFN’s leadership 30 | February 2024

In collaboration with Sandrex Project Management, who served as grant co-writer, finance reporter, and community liaison, the preliminary designs of the ESMP were refined into the first full concepts of the eventual project. At the same time as FMFN was activating their early project planning stages, the neighbouring Regional Municipality BUILDING RELATIONSHIPS of Wood Buffalo (RMWB) approached Building on the relationships forged FMFN to discuss collaboration opporin the delivery of the ESMP, FMFN and tunities for a regional wastewater systhe FMFN’s Industry & Government tem.

would also allow FMFN to focus on the collection and distribution of water and wastewater within their community which mitigated some of the Nation’s long-term operational risk. With this regional servicing concept in place, the project team began lobbying Indigenous Services Canada (ISC) in earnest for a funding plan to bring this enormous undertaking to life. SECURING AREA 1 FUNDING

Due to the complexity of the project, it was broken down into seven areas. The first grant aimed to unlock funding for Area 1, which would contain the central components of the greater system, including: • New water and sewage connections to the RMWB regional systems. • New potable water reservoir and pump station. • Connection of all existing buildings to the new, centralized water and wastewater system. • New wastewater lift station to discharge sewage to RMWB regional system. • Improvement of existing roads and stormwater drainage ditch system during the deep utilities installation process. In 2019, the initial funding grant was secured from ISC to undertake Area 1 and the relationship with ISC switched from lobbying to collaboration. ISC funding enabled the project scope to include specific features that would benefit the community for generations to come, including: • Fire pumping capacity, which meant the community would have fire protection for the first time. • A natural gas backup generator, which delivered water and sewer servicing in times of emergency and required less maintenance and environmental risk than diesel tank-supplied alternatives. • A fully concrete pump station building structure, which provided noise abatement, security and longevity. • An inline grinder upstream of the sewage lift station, which would protect the lift station pumps from large solids in the future wastewater stream. Once total project funding was secured, construction was awarded to Chandos Construction. Together with www.esemag.com @ESEMAG

This 3D model was delivered to the construction team, who relied on it to identify assembly efficiencies and resolve them before pumphouse construction, reduce construction costs and schedule, and improve quality control by pre-fabricating all facility piping. Despite a global pandemic, significant geo-political world events, and unprecedented supply chain challenges, Chandos completed construction in the fall of 2023. BUILDING A DEPARTMENT

As project construction proceeded, FMFN turned their focus to facility operations and the creation of a new water and wastewater operations division. Because it would own and operate the new water and wastewater system, staff from the community would need to be trained and certified for specialized work. Hiring community members was a priority for FMFN to reduce

labour flight risk, simplify infrastructure troubleshooting, and create permanent, skilled careers in the community. First, the skills and qualifications required to operate the pumphouse, reservoir, and linear infrastructure were identified. Next, the project team lobbied ISC for a reliable funding stream to cover a qualified operator salary. Finally, operations staff were hired. New operators received direct mentorship with “set-up-for-success” initiatives, including technical orientations and attendance to industry-leading networking conferences. A $25K training fund through McElhanney Cares , McElhanney’s social responsibility program, was also established. Distributed in annual $5K increments, this fund secures important training not covered by ISC, such as provincial operator certification and project management training. Corey Wiltzen, FMFN member and a water plant operator trainee, says he is proud of the collaborative efforts

Not only are we securing safe drinking water for our present and future generations, but we are also providing Nation members like myself with the opportunity to start a career in a vitally important field.” REGIONAL RELATIONSHIPS

As early as 2003, the Fort McMurray 468 First Nation was approached by the Regional Municipality of Wood Buffalo to construct a regional drinking water system that would extend water pipes between RMWB communities. This system included a new right of way on FMFN lands and laid the foundation to integrate efforts again in the future. When RMWB approached FMFN in 2018 for a second right of way, as part of the construction of a regional sewage system in the area, both organizations saw the opportunity to collaborate.

niagaracollege.ca Environmental Science & Engineering Magazine

One of the most significant ways RMWB showed collaborative engagement was through the support of FMFN’s new McElhanney and ISC-funded water and wastewater operator programs. In 2020, FMFN hired water and sewer operators in anticipation of the activation of Area 1. But when both RMWB and FMFN projects experienced scheduling adjustments, a deal was struck for the new FMFN operator staff to work embedded in the RMWB water and wastewater department team. This arrangement remained in place until Area 1 activation in 2023. It also deepened the relationship between RMWB and FMFN, while providing valuable technical expertise to the new FMFN operator staff.

tionship-based strategies that will speed up construction and reduce impacts on community members. Both water distribution and sewage collection systems are jointless. High density polyethylene piping (HDPE) systems, which permit all mainlines to be installed using a less-invasive horizontal directional drilling (HDD) method, minimize disruptions on the community, decrease impact on existing roads and landscaping, and reduce installation schedules. FMFN selected a low-pressure wastewater collection system, which permits flexibility in how connections are made to existing houses and minimizes plumbing modifications. Services to each building are delivered through HDPE systems, again allowing extensive HDD installations and flexibility with system routing. System routing was an important consideration, as McElhanney plans were made with awareness of FMFN’s shared knowledge of the land, significant cultural burial sites, and other unique features. Today, fire hydrants can be spotted throughout the community for the first time. The promise of fire protection extending from FMFN’s new pumphouse provides a sense of security previously unknown to community members.

Operation staff gained invaluable experience mentoring under RMWB staff.

The Fort McMurray 468 First Nation’s vision, to thrive through economically sustainable opportunities that create self-sufficiency and a vibrant, healthy community, is being realized. Because of the dreams of FMFN leadership, a decades-old truck haul system has been replaced with reliable and safe water and wastewater infrastructure. However, this dream activated more than infrastructure. It also gener-

ated these developments: • An innovative network of multi-jurisdictional relationships was established and nurtured. • The difficulty and complexity of starting a water and wastewater operator division was tackled, to the long-term economic and social benefit of the community. • Opportunities for future development that manifest FMFN’s vision, including a health centre and a Band administration/ community centre, have already been unlocked because this foundational water and sewage infrastructure is in place. Perhaps most tellingly, remote community members have sensed the energy on the reserve. There is an increased demand to return home, evidenced by a growing backlog of FMFN members on the community’s housing wait list. The innovative network of relationships that FMFN built to support this project is a model that other communities can look to for inspiration and project success. Within FMFN, the relationship network is already being applied to further new growth and opportunities. Andrea de Vries is with McElhanney. Email: adevries@mcelhanney.com

In a worst-case scenario, ice formation can cause a water tank to burst. This not only poses a threat to the local community but creates physical damage to the water tank, leading to costly financial implications. Because the water within tanks is also used for firefighting, ice prevention is crucial. When ice forms across the sur-

face water of a tank, it also adheres to the edges of the tank. When a large volume of water is rapidly pulled out of a tank during a firefighting operation, it can leave a “cake” of ice hanging at the top. This is a very dangerous situation that can cause irreparable structural damage if the ice breaks and falls. However, the formation of ice in water

tanks can be prevented by using a combination of “active mixing” and regular maintenance. Active mixing circulates the water at regular intervals, using a motor-driven impeller. This pulls warmer water from the bottom of a tank into the upper layers, which get colder during winter, and prevents ice from forming. Kasco’s CertiSafe mixers can be installed in a day through a tank’s centre roof vent. Divers attach chains near the vent and set the mixer at the correct level for optimum operation, using a SM100 suspension mount. A SCADA control panel allows for remote operation and monitoring. Ice prevention isn’t the only benefit of active mixing. This technique can also solve water quality issues such as thermal stratification, chlorine residuals, improving water quality, reducing sediment accumulation, lowering the rate of disinfection byproducts, eliminating chemical stratification and reducing differences in water taste and odour. CertiSafe mixers come in multiple sizes, with NSF approval for potable water tanks as small as 76,000 litres and models designed for mixing tanks over 3.8 million litres. They are fully submersible up to a depth of 15.25 metres and can be mounted using a floor, suspension, or pipe mount.

Asset management strategies in remote and extreme environments By Tacoma Zach

t was an unusually warm March in Southern Ontario. There had been several warmer days with the associated freeze-thaw cycles between night and day. One of my duties as a young engineer in the contract operations business was to check on various remote, unmanned customer sites. I performed inspections, bump-start tests and general functionality testing. When required, I scheduled the emptying of various waste storage tanks with the designated haulers. It had been about two weeks since my last visit to a landfill leachate site where its tanks were due to be emptied. This client had acquired and repurposed three large stainless steel beer tanks to function as interconnected leachate storage tanks. These were some of the best-looking storage tanks I’d ever seen. Each shiny tank was over 12 metres long and more than three metres in diameter. This particularly warm morning there was lots of moisture in the air with fog and mist - something we paid no mind to as we were more concerned about heavy freeze temperatures. As the waste hauler’s truck connected to the transfer header, we went through the established safety and functional check list, opened all the tank vents, and began what was supposed to be a routine transfer, as we had done hundreds of times before. Since the tanks were fairly full, we decided to open the interconnecting valves to equalize the pressures and drain them in unison. About four minutes into the transfer, we heard some distant but deep thumps, like a dump truck a half a kilometre down the road getting a load. This seemed normal and we didn’t react. A few seconds later the noise grew louder and in rapid succession we heard three massive bangs, like giant kettle drums right beside us. We shut off the pumps and the power to the pump system and quickly scanned www.esemag.com @ESEMAG

the area for an explosion or fire, the worst-case scenario. Everything was calm with dim but ambient light. Nothing. Then we walked around and discovered what had happened. All three massive, beautiful, stainless steel, horizontally-mounted tanks, had caved in and looked like giant squished water bottles on their side. The vents were all open and since the tanks were interconnected if one had stuck, another vent would facilitate the breathing of the tank. How could this happen? ADJUSTING ASSET STRATEGIES IN REMOTE AND EXTREME ENVIRONMENTS

Appropriate asset management strategies are essential for achieving asset management goals and delivering value from assets. When assets are operating in remote and/or harsh environments these strategies must be adjusted to reflect the impact of different stressors and considerations. A great friend and mentor of mine used to say, “assets are a collection of failure modes, and our job is to manage

the failure modes, if warranted.” This was a strategy defining statement on so many levels. He meant that assets can only fail based on what they are made of and the way they are assembled. As such, we need to pay attention to how those components fail and what causes them to fail. If possible, measure for both internal and external stressors, and intervene appropriately when warranted. When operating assets in remote and cold environments, here are three principal considerations for adjusting asset strategies: UNDERSTAND HOW ASSETS FAIL: PAY ATTENTION TO THE PHYSICS OF FAILURE

In our industry, there can be a bit of ambiguity about what is an actual failure mode. For example, the often recorded or cited “failure mode” of a stopped shaft is “it seized”. We intuitively know what is meant, but ”seized” is a result and not a failure mode. In Reliability-Centered Maintenance: RCMII, John Moubray links the failure continued overleaf… February 2024 | 37

mode to the asset’s functional failure and defines a failure mode as “events which are reasonably likely to cause each failed state.” He goes on to include both mechanical reasons as well as human factors as causes. The causes could be lack of greasing, the wrong grease, or water contamination in the grease due to a leaking seal, etc.

get start up capacitor failure modes in a valve assembly. For example, assuming all other things are equal, an incorrectly sized pump and wet well for the expected volumes at certain times of the year can cause too many stop-starts. This stress on a motor will manifest electronic-related failures long before corrosion-related failures. Both are possible failed states, but one will manifest earlier THE IMPACT OF STRESS AND CONTEXT ON AN ASSET’S based on the local context.

Similarly, you won’t motor inspection and meggering (using

an insulation tester resistance meter) would be warranted more frequently than a corrosion inspection. The failure modes also inform other aspects of the asset management strategies: what local spare parts should be stored in inventory; how many levels of protection should be applied; redesign considerations or installed spares; acceptability of run to failure or not. These later decisions are usually influenced by riskbased decisions supporting the overarching operation service level objectives. UNDERSTAND THE LOCAL CONTEXT: EVALUATE STRESSORS AND CONDITION

Since different stressors on an asset will target different parts of it and cause certain failure modes to manifest earlier than others, it is possible to design an inspection regime tailored not only to detection of the asset’s typical failure modes, but specifically to those modes more likely to occur given the predominant local conditions. Having worked in both very cold and very hot desert climates, I have seen how important it is to at least try to anticipate which failure modes will be revealed by the local context and stressors. Typical known stressors like temperature, vibration, pressure deltas, stop-starts, corrosivity, abrasiveness, contamination of oil or grease, incorrect grease or oil, UV radiation, lack of environmental control and stray current, are well known. Some of these stressors may be linked, causal, or just concurrent with one another. Extreme temperatures, wide seasonal swings or very rapid swings in temperature can have a serious impact on an asset’s performance. Some materials have a large enough coefficient of thermal expansion that extremes cause parts to be “just-out-of-spec” on a regular basis. They may lose mechanical suitability at the extremes, or their insulative ability means they change more slowly than their mated metal parts. This can exacerbate tolerance issues, causing leaking or cracking prematurely. A material’s elastic modulus may become too high at extreme cold and result in cracking, or total failure, even under normal stress loads. Without proEnvironmental Science & Engineering Magazine

tective mitigation, plastic valves or pipes, and even poorly-welded and low-grade metal pipes under the right load will typically fail as the temperature drops. In this case, seasonal heat trace or insulation installation and inspection should become part of a preventive maintenance program during winter months. Similarly, oil can “wax” at extremes of lower temperature, or low temperature oil can be too thin at higher operating temperatures. This may require a different grade of oil in summer versus winter and would be articulated in a seasonal preventive maintenance program. Any of these conditions may foster consequential damage and accelerate declining asset condition sooner than expected. Always double check that the specs you are following reflect the environment you are operating in. It is important to remember that there is no such thing as inventing a new failure mode for an asset. Instead, the manifestation of that specific failure mode is driven by the local context and must be considered in adjusting and managing asset strategies. Understanding these stressors is critical for effective preventive maintenance and broader asset management programs.

Or a more robust asset could be selected, or additional layers of protection/mitigation applied to safeguard asset performance under extreme conditions. In remote situations, the strategy moves away from frequent intervention and preventive maintainance programs to a more robust overall design to manage the extremes of temperature. Strategic decisions on how to provision the plant inventory, how to change the design, or add layers of protection are all influenced by the local remote context and the impact on the organization’s risk profile.

ture in the atmosphere, had filled the canister and both downcomer pipes with enough water such that when the tanks were being emptied, the water was drawn up the feed vent pipe until the tank walls caved in, responding to the pressure differential. Force builds up very quickly over large surfaces, and these tanks were very big. While we had been concerned about deep freeze events and checked for frozen pipes and leaks, the practice of checking for water in the carbon canister was a summer job. We didn’t recognize that the operating environment had changed. A summer failure mode showed up in winter. Fortunately, the tanks were resilient.

UNDERSTAND YOUR CONSTRAINTS

Preventive maintenance and asset management strategies are also affected by the remoteness of an operation. Are the assets in a remote location co-located with staff, or are they remote as well as unstaffed? While placing monitors and sensors on critical equipment is standard procedure (or should be), the ability to intervene quickly, or at all, will determine the broader asset management strategies, as well as some of the logistics of the maintenance strategies. Either way, remote assets will require a larger spare parts inventory given the extra time for supply chain delivery issues. Additionally, remote, unstaffed assets may also require further strategic decisions if time to proximity is greater than the speed with which the asset can fail. Additional redundancy could be the right strategy. For example, installing five pumps when only three are needed. www.esemag.com @ESEMAG

WASTEWATER

California moves one step closer to direct potable reuse of wastewater By ES&E Staff

alifornia’s State Water Resources Control Board has voted in favour of adopting direct potable reuse regulations that would allow municipalities to blend purified wastewater into a local drinking water supply. The push to utilize wastewater as a drinking source has been some 13 years in the making for the Golden State, over which time it has struggled with several extreme droughts and dwindling reservoirs. But the state board approval will still need to be accepted by California’s Office of Administrative Law, which could add up to a year before the process of building new water recycling plants becomes a reality for the state’s nearly 40 million residents. Regulators said wastewater treatment will consist of “no less than four separate treatment processes” for each of the following pathogens: enteric viruses, Giardia lamblia cyst, and Cryptosporidium oocyst. Treatment mechanisms will also have to include one membrane physical separation mechanism, one chemical inactivation mechanism, and one UV inactivation mechanism, according to the regulations. Other processes include a reverse osmosis membrane process and an advanced oxidation process. Agencies in charge of direct potable reuse (DPR) will also need to establish a total organic carbon chemical control point and a control point monitoring location that provides representative sampling of the advanced treated water prior to distribution. “Direct potable reuse projects, when implemented, may allow public water systems access to water sources formerly discharged into the ocean as municipal wastewater, which would reduce the dependence of these water systems on other sources of water and result in more water available for uses, such as the protection and enhancement of nat40 | February 2024

ural resources and the environment,” states the DPR regulation. The new California regulations create additional flexibility by allowing advanced purified water to be added directly into drinking water systems where it isn’t feasible to first blend it into a larger body. Colorado’s Department of Public Health and Environment adopted DPR regulations last January, though no utilities have announced any actions as yet around the opportunity. Arizona, Texas and Florida also have regulations in the works. WateReuse California said it has collaborated with the Water Board and other stakeholders for over a decade to reach the DPR milestone. While California has used recycled wastewater for things such as ice hockey rink surfaces, and some crop irrigation, the ability to develop infrastructure to utilize advanced-treated wastewater as a drinking source is a first. After mul-

tiple reviews by independent panels of scientists, state law required the California Water Resources Control Board to approve regulations by the end of 2023. Many studies have shown that highly-treated wastewater is essentially “purer” than standard tap water. Minerals are often stripped and then added back to the water. In 2020, the University of Calgary’s Advancing Canadian Water Assets program formed a partnership with Alberta’s Village Brewery to sell limited edition beer brewed with treated wastewater.

(HGSD) in 1975 to monitor groundwater extraction and implement more sustainable practices. In 1999, HGSD released a regulatory plan that would require Houston and surrounding areas to shift their drinking water supply from groundwater to surface water. The West Harris County Regional Water Authority (WHCRWA) was founded in 2001 to carry out HGSD’s regulations. As population grows, HGSD’s policy aims to prevent subsidence by reducing draw from groundwater in three stages. Stage one, completed in 2010, required 30% of drinking water supply to come from surface water instead of groundwater. The next stage, scheduled for completion in 2025, increases that requirement to 60%. The final stage, projected for a 2035 completion, will see surface water make up 80% of the Houston area’s drinking water supply.

treated water they receive meets requirements for total chlorine residuals. Bryan Thomas, area manager at Inframark, the private utility that operates the WHCRWA, says the two new pump stations will put more emphasis on WHCRWA’s role. Blending water from different sources makes retreatment both more complex and more important, as the water from each of the new pump stations could contain different levels of chemicals. WHCRWA will need to manage these levels to continue to stay in compliance. RELIABLE ANALYZERS PROVE KEY TO SUCCESS

“It took up a lot of our time.” The demand on facilities will only increase as they process a larger volume of water. Right now they treat about 106 million litres of water a day. After the expansion, it will be 430 million litres per day. After comparing several options, the WHCRWA selected two In-Situ Inc. UV 2250 ChemScan analyzers for chloramination. They provide continuous measurements of nitrate and ammonia to verify that WHCRWA meets residual limits after retreatment. “We were expecting a little bit of a challenge, adapting to something new,” says Thomas of the transition, adding that “we were given all the information we needed and the two new ChemScan analyzers do the job of the six analyzers we had before.” Though the expansion project will change operations for the plant, the new analyzers bring some peace of mind. “It’s nice to know that if we did have issues where we weren’t getting a consistent residual, that we have something that can actually give us a real number. It’s not something that we have to guess at or constantly keep an eye on,” says Thomas. “Having reliable analyzers is going to help us maintain residuals and not have to worry about levels being too low or high.”

Anticipating this, WHCRWA started looking for replacement analyzers in 2019. It needed equipment to provide accurate, continuous data, in order to blend several water sources successfully and maintain consistent residuals.

ENERGY EFFICIENCY

Best practices for energyefficient evaporation processes By Arnold Kleijn

vaporation is a process where a material moves from its liquid state to a vapour (or gas). The most common example of evaporation seen in everyday life is the transfer of water from the earth’s surface to the atmosphere as part of the water cycle. When liquids evaporate, and materials which they contain in solution or suspension are left behind, this becomes a useful process to concentrate solutions or to help separate materials. Evaporation is different from dehydration or drying because the product is a concentrated liquid, rather than a dry solid. However, evaporation and drying

processes can be combined: an evaporation process first removes the bulk of the water, and a final dryer eliminates the last bit, to obtain the final dried product. As evaporation plants are usually more energy-efficient than dryers, it makes sense to combine the two technologies. Evaporation is different from distillation: a distillation process separates two or more liquids that have different boiling points (and which normally contain no solids). In contrast, evaporation eliminates water from a solution that contains dissolved and/or suspended solids, thus obtaining a more concentrated solution. In general terms, the rate of evaporation

processes often use a reduction in pressure to speed up the evaporation process. Evaporation is used for different purposes in multiple industries and sectors. In the food industry, some products are concentrated to increase shelf life, reduce volume or weight, or reduce storage and transport costs. In contrast, in the pharmaceutical sector, evaporation is often used to create concentrated solutions which can then be dried to create powdered products. In each sector, the basic principles of evaporation remain the same – the removal of water (or another solvent) from a solution by converting that water or solvent into its vapour phase. Different techniques (using different temperature and pressure conditions) can be applied in different situations. The type of evaporation which is most suitable for a particular purpose depends on a large number of factors, including the nature of the solvent and the solution, the required end products, and the energy available for the process.

The reuse of evaporated steam increases the energy efficiency of the plant. For example, if a TVR compressor is applied to a one stage evaporation plant, reusing 50% of the evaporated steam, this will then double the energy efficiency, compared to the system without the TVR compressor. TVR compressor can be combined within multi-effect evaporation plants, further optimizing the energy consumption. Mixing evaporated steam and boiler steam in a TVR device usually gives a net steam which is much closer to the boiling point than pure boiler steam. This makes TVR processes difficult to apply for liquids with high boiling point elevation, and unsuitable for products with high viscosities and lower rates of heat transfer. Where thermal energy (steam or hot water) is not available but electrical power is, a lobe or fan compressor can be used to recompress the steam which has been generated. By compressing the evaporated steam, the temperature and pressure is increased to a point where it can provide useful energy for evaporation. This way, the same kg of steam which is evaporated from the product is reused as the thermal energy source for the same evaporation stage. The use of mechanical vapour recompression (MVR) compressors is one of the most economical evaporation techniques,

steam is condensed on the service side of the evaporator itself, also eliminating the cost of a cooling tower and corresponding cost of water for condensation. However, MVR systems often have higher capital costs due to the need for a larger evaporator and the lower supply temperature. As with TVR systems, MVR compressor systems are less suitable for products with high boiling point elevations or products with increased In a multi-effect evaporator, the evaporated steam generated in one stage of evaporation is used viscosities. as the thermal energy source for the next stage to reduce overall energy requirements.

ZERO LIQUID DISCHARGE (ZLD)

Perhaps the ultimate use of evaporation technology is for zero liquid discharge systems, which combine evaporation systems with solids precipitation or crystallization to achieve a net-zero liquid output from a process. The evaporator section concentrates the product as much as possible, typically to the point of saturation, before it is sent to the crystallization section where the solids are suspended and separated from the saturated solution. This saturated

solution (supernatant) is recycled back into the evaporator and the process is repeated or continued. For products with a steep solubility curve (high concentration at high temperature and low at low temperature) additional cooling to the solid’s precipitation tank will help the solids to precipitate quicker and settle out. ZLD systems are complex processes which are specifically designed for each application. In most cases product trials are required to

establish the correct process parameters. Corrugated tube evaporators offer high heat transfer solutions for low to medium viscosity fluids. Plate and falling film evaporators can be applied for low viscosity fluids that are easier to concentrate. Arnold Kleijn is with HRS Heat Exchangers.

EXCESS SOILS

Naturally-elevated metals concentrations are resulting in more landfilling and less beneficial reuse of soils By Allan Clifford Lawton and Christopher Gerard Paré

he Ontario Ministry of the Environment, Conservation and Parks (MECP) set background standards for metals in soil in 1993 (Ontario Typical Range [OTR] adopted as Table 1 metals standards). Values were based on native soil samples collected and analyzed throughout Ontario. Natural metals concentrations are not uniformly distributed throughout Ontario. Naturally-occurring metals in soils derived from bedrock containing elevated concentrations of select metals can exceed the Ontario background standards in certain regions and have been documented by the MECP With the introduction of the Excess Soil Regulation (Ontario Regulation 406/19) and Rules, contractors in Ontario must identify local reuse sites to accept the excess soils generated during and consultants. excavation activity.

PROBLEM

With the introduction of the Excess Soil Regulation (Ontario Regulation 406/19) and Rules, contractors in Ontario must identify local reuse sites to accept the excess soils generated during excavation activity. The project area may not have a history of past anthropogenic activities that would impact soil, but naturally-occurring metals concentrations above provincial background standards may be identified in soil samples and dictate reuse options. Under this regulation, excess soils containing specific metals within the range of natural background concentrations may be prevented from beneficial reuse. Additionally, Excess Soil Quality Standards (ESQS) have created limitations that prevent the use of statistical analysis because ceiling values are set lower than local natural background concentrations. In the Windsor-Essex region of Southwestern Ontario, data collected from soils not impacted by anthropogenic activities may contain concentrations of metals above background. These metals 48 | February 2024

concentrations are within natural ranges of the region, but they are above background standards. Thus, they are characterized as “impacted” above Table 1 ESQS (Agricultural Use). Therefore, these excess soils are not acceptable at Table 1 Standard Reuse Sites. Consequently, alternative reuse sites need to be identified. In some cases, these excess soils are directed to landfills, increasing project costs and reducing landfill capacity.

EXCESS SOILS A 1998 Ministry of Environment report titled “Investigation into Chemical Composition of Shales in Ontario” noted “beryllium concentrations to be elevated above normal surface soil background.” As a result, an exception to the use of the OTR is being used for beryllium, as SDB (Standards Development Branch) is proposing to use 2.5 mg/kg as the background concentration for beryllium for all land use categories. Black shales have been recognized in scientific literature as containing significant concentrations of metals and other elements. In Geological Survey of Canada Open File 8452, additional data is provided with respect to metals in black shale. It says that in areas underlain by black shale near Sarnia-Windsor and the Ottawa Valley east of Ottawa, till is relatively enriched in As, Mn, Mo, Na, Ni, U, Sb, and Sr. It also states, “In the area west of London, for example, Mo is generally enriched in comparison with adjacent regions.” Based on a review of maps presented in this report regarding till geochemistry, arsenic and molybdenum are enriched in the Sarnia-Windsor area.

unicipal wastewater effluent discharges and land application of treated biosolids are important pathways of perand polyfluoroalkyl substances (PFAS) to the environment, as municipal wastewater treatment plants (WWTPs) are not designed to remove these or other chemical substances. Previous research has shown only partial removal and, in some cases, apparent formation of PFAS during some wastewater treatment processes, which was attributed to transformation of unmeasured PFAS precursors. Some PFAS have been subjected to various industrial production phaseouts and regulatory actions beginning in the early 2000s. In May 2023, the Government of Canada published a draft State of PFAS report and a Risk Management Scope for PFAS. It proposed to conclude that the broad class of PFAS meets the criteria for toxic to the environment and human health under the Canadian Environmental Protection Act, 1999. Using the results of Environment and Climate Change Canada’s (ECCC) Wastewater Monitoring Program, we recently evaluated trends of PFAS concentrations in 27 representative Canadian WWTPs, assessed changes during treatment, and evaluated time trends in influent, effluent and biosolids between 2009 and 2021. The results were published in Science of the Total Environment. Two PFAS, perfluoroethylcyclohexane sulfonate (PFECHS) and perfluorobutane sulfonamide (FBSA), were analyzed at ECCC in the laboratory of Dr. Amila De Silva. The other 40 PFAS included in this study were analyzed by SGS AXYS Analytical Services Limited (SGS AXYS).

aerobic conditions but could also be occurring under anaerobic conditions. Any chemicals not degraded during aerobic and anaerobic digestion will instead become concentrated because volatile solids in the sludge are reduced during treatment. Alkaline treatment is typically associated with reduced contaminant concentrations as a result of dilution from the alkaline admixture. Dewatering is not typically associated with effective removal of contaminants, compared to other sludge treatment types. In addition to the factors discussed above, concentrations of PFAS in biosolids are dependent on the type of wastewater treatment that preceded the biosolids treatment, the blend of primary versus waste biological sludge, and the transformation of PFAS precursors during both wastewater and solids treatment. Most biosolids collected between 2018 and 2021 as part of our study contained PFOS concentrations below the proposed Canadian Food Inspection Agency (CFIA) interim standard of 50 ng/g, except for one plant where some samples contained PFOS concentrations greater than 50 ng/g.

benefits, such as enhanced soil health, improved nutrient recycling, reduction of costly fertilizer use, strengthened farm economies, and improved carbon sequestration which helps combat climate change. Our samples were collected from a large cross-section of municipal WWTPs. Therefore, these results indicate that Canadian biosolids are generally suitable for application to agricultural fields, with respect to PFAS, when they are not impacted by industrial sources of this class of chemicals. Several emerging PFAS were not detected in wastewater influent, efflu-

The extent of PFAS removal during wastewater treatment is the balance of two competing processes: partitioning to solids and transformation of precursors. Removal and formation patterns varied highly within and between treatment types, indicating that the extent of removal and formation depends highly on factors beyond general treatment type. PFAS TIME TRENDS IN WASTEWATER AND BIOSOLIDS

The concentrations of long-chain perfluoroalkyl carboxylates (PFCAs) (including PFOA) decreased over time in influent, effluent and biosolids, which reflects industrial production phase-outs and regulations. The concentrations of long-chain perfluoroalkane sulfonates (PFSAs), which consist primarily of PFOS, increased with time in wastewater influent. This was unexpected because PFOS was phased-out of production by North American industry in the early 2000s and is subject to prohibition under the PCTSR in Canada. We believe that the time trends of PFOS in influent observed in this study was an artifact of changes to the analytical methods. The samples were filtered prior to 2018, but analyzed as whole water samples between 2018 and 2021. Therefore, the concentrations measured prior to 2018 in influent samples reflect the dissolved and not particulate phases and may be underestimated. Filtering would have less of an effect on short- compared to long-chain PFAS and precursors because short-chain PFAS are often not detected in suspended particulate matter and they are typically found predominantly in the dissolved phase. Long-chain PFSA and PFOS concentrations did not change with time in either effluent or biosolids. Biosolids were anaEnvironmental Science & Engineering Magazine

lyzed as whole samples throughout the sampling period and effluent contained total suspended solids concentrations that were much less than in influent. Therefore, it is unlikely that the time trends of PFAS in biosolids and effluent would be affected by filtering. This suggests that while the apparent increase of PFOS concentrations in influent was related to changes to the filtering protocol, the response time of PFOS to industrial phase-outs and regulations is slower than other regulated PFAS. In comparison, PFOS concentrations were observed to decrease with time in Canadian surface water and drinking water. Wastewater matrices are more complex compared to other media, which could lead to more variability in data and relatively low power to detect trends. Perfluorohexanesulfonate (PFHxS), classified as a long-chain PFSA, is of interest because it was listed in Annex A under the Stockholm Convention in 2022 and was phased-out of industrial production in the early 2000s. The concentrations of PFHxS decreased significantly (p<0.05) in wastewater effluent, but did not change significantly (p>0.05) with time in either influent or biosolids. Concentrations of short-chain PFAS in wastewater influent and effluent increased consistently between 2009 and 2021. These increasing patterns reflect the use of short-chain PFAS as replacements for phased-out and regulated longer-chained PFAS. Short-chain PFAS were not consistently detected in biosolids. FUTURE DIRECTIONS

Although we quantified 42 PFAS in this study, this is a small number of the total substances in the PFAS class. Phosphate-ester surfactants, such as fluorotelomer phosphate diesters, made up a substantial fraction of PFAS in the particulate phase of wastewater and biosolids collected from WWTPs in the United States and Nordic countries. However, they were not measured in this current study. Further work is needed to expand the PFAS routinely targeted in wastewater monitoring programs and/or to apply techniques that better evaluate PFAS as a class, such as the total oxidizable prewww.esemag.com @ESEMAG

Canadian researchers take on 6PPD‑quinone By David Nesseth

he deaths of some 40 coho salmon in Brothers Creek near West Vancouver, British Columbia in late 2023 returned Canada’s attention to the risks of a tire preservative, now identified as a toxic roadway runoff chemical, which the B.C. government and the U.S. Environmental Protection Agency have signaled moves to regulate. Discovered three years ago by Washington-based researchers trying to solve the mystery of annual pre-spawn coho salmon die-offs after heavy autumn storms in the Pacific Northwest, 6PPD and one of its problematic transformation products, 6PPD-quinone, have since been the focus of intense study at several Canadian universities and drawn the attention of scientists at Fisheries and Oceans Canada. Both are busy collecting data and testing ways to mitigate the effects of the antidegradant that flakes off with rub56 | February 2024

ber onto roadways, activates as a toxin by sunlight, then washes into stormwater drains through rain and snow. The specific chemical signature associated with particles shed from vehicle tires in motion was discovered in late 2020. A mystery that lasted decades, over which time some species of salmon became endangered, was solved. After ruling out high temperatures, low dissolved oxygen, or any known contaminant such as high zinc levels, the researchers isolated and tested thousands of molecules found in tire-wear particles. “We then spent about two-and-a-half years separating this complex mixture to finally generate a chemically simple extract that was lethal to coho salmon. There were four chemicals detected out of the more than 2,000 present, initially,” said University of Washington Tacoma engineering professor, Edward Kolodziej in an interview with ES&E Magazine “Here, through the incredi-

bly hard work of Dr. Zhenyu Tian, we finally identified the primary causal toxicant for coho mortality events as a chemical called 6PPD-quinone. It is a previously unknown chemical product of the common tire rubber antioxidant and antiozonant 6PPD that’s generated when 6PPD reacts with atmospheric ozone on tire rubber surfaces.” When it came to 6PPD-quinone, salmon died during their tests within five hours of exposure to concentrations as low as 0.8 micrograms per litre. What stands out to Kolodziej now is just how toxic and ubiquitous 6PPD-quinone really is. “Tire rubber-derived chemicals like 6PPD-quinone are just everywhere,” he says. “While many fish seem to be insensitive to 6PPD-quinone, its high toxicity to coho salmon makes 6PPD-quinone the second most toxic compound to aquatic organisms ever identified.” In Canada, the discovery of 6PPD-quinone sent researchers into motion. Two avenues emerged: one to find safer alternatives to prevent tires from cracking, and another to better manage stormwater. Almost immediately, research scientist Tanya Brown with the Ocean Sciences Division of Fisheries and Oceans Canada (DFO) was on the phone with First Nations and conservation groups in B.C. “I think in a month I was reaching out to people,” recalls Brown, when speaking with ES&E Magazine. “We were trying to leverage funds within DFO to start up the project so we didn’t get on the ground sampling until that September, but we were actively speaking to and meeting people and basically visiting a number of sites leading up to that.” Brown’s team is currently monitoring for roadway runoff chemicals in 70 salmon-bearing creeks around coastal B.C. The work is being used to create a map of toxic B.C. hotspots where local governments can apply mitigation techniques to protect fish. Monitoring sites are located around Metro Vancouver, Squamish, and all over Vancouver Island, including Brothers Creek, the site of the recent fish die-off in November. While Brown’s team found low levels of 6PPD-quinone related to the die-off, their monitoring station was quite a bit downstream from the event. They have since added additional equipment closer Environmental Science & Engineering Magazine

to the highway to see if their monitoring data changes. Brown, who is also involved in controlled lab exposures to learn more about the levels at which 6PPD-quinone can be fatal to certain fish, says the B.C. government is developing environmental quality guidelines for either soil or water, based on 6PPD-quinone lab findings and monitoring data. This may ultimately progress into a provincial regulation to help better protect aquatic life. “I think it’s great the amount of energy and attention that this chemical is being given right now. But, I also don’t want people to forget that we are dealing with a cocktail of chemicals out there, and it’s not only 6PPD that’s toxic in terms of road runoff,” says Brown. “But, I think we can use this chemical to help clean up our receiving environment and put a little bit more pressure on.” One of the first Canadian explorations of 6PPD-quinone occurred at the University of Saskatchewan (USask), which hosts an Aquatic Toxicology Research Facility. The university partnered with the City of Saskatoon to understand the chemical’s potential impact on other aquatic life in the South Saskatchewan River, as well as unknowns about how extreme cold temperatures affect the chemical’s degradation derivative. Researchers like USask assistant professor, Markus Brinkmann, used samples taken from snow facilities, snowmelt puddles, and about a dozen outfall sites along the South Saskatchewan River within the city in 2019 and 2020. Some of the research utilized a new chemical hazard assessment tool called EcoToxChip, recently developed as part of a large Genome Canada initiative to identify early toxicity indicators, and predict the vulnerability of target fish species. Brinkmann has also been involved in federal grant research projects on 6PPD-quinone, as well as other tire byproducts and antimicrobials that have also posed a threat to aquatic species. His research proved that rainbow and brook trout are also vulnerable to the effects of 6PPD-quinone, as the fish died after just four days of exposure to stormwater runoff events, even in small concentrations. Another researcher at USask, Dr. Jafar Soltan, professor of chemical and biolog-

biochar, a carbon-rich material produced during pyrolysis that is a thermochemical decomposition of biomass. University of British Columbia (UBC) researchers, Timothy Rodgers and Rachel Scholes, have also been exploring ways to stop 6PPD-quinone from spreading to waterways. Through the use of rain gardens, also known as bioretention cells, which are engineered to reduce flooding and soak up contaminants, the researchers say that the majority of the chemical could be blocked from entering waterways during an average year under typical storm conditions.

STORMWATER found only about 2% to 5% of the chemical made it through, with about 75% captured by the soil and plants. A month after the Brothers Creek fish kill, UBC’s Department of Civil Engineering received $1.8 million in funding to assess the prevalence of stormwater contaminants in salmon-bearing streams in B.C. and identify opportunities for green infrastructure interventions to protect salmon populations from toxic road runoff contaminants. “Although finding safer alternatives to 6PPD will provide the most complete protection for salmonids and other potentially sensitive aquatic organisms, the efficacy of bioretention systems means that in the short term, stormwater managers can protect sensitive populations by redirecting runoff away from streams and toward engineered systems such as bioretention,” the UBC study states. Finding that safer alternative has been underway since the discovery of 6PPD’s toxic byproduct. In October 2023, California’s Department of Toxic Substances

Control added tires containing 6PPD to its Safer Consumer Products Regulations. Manufacturers are now forced to list their tires as “priority products” that require an “alternatives analysis” and determine how best to limit exposures or the level of adverse public health and environmental impacts posed by 6PPD. The state says it’s working with the U.S. Tire Manufacturers Association (USTMA) to navigate the process. The U.S. Environmental Protection Agency (EPA) intends to amend emission standards for Hazardous Air Pollutants for rubber tire manufacturing, as required by the Clean Air Act. It is a move that will cost the industry an estimated $20.8 million per year to address, according to the Tire and Rubber Association of Canada. The USTMA has pledged to work with the U.S. EPA and is currently evaluating whether there is an available alternative to 6PPD for tire preservation. “At present, 6PPD presents a critical and essential use in tires,” announced

the USTMA in a recent statement. “While many potential alternatives are being considered, none has been demonstrated to be technically feasible for meeting federal safety requirements. Any premature prohibition on the use of 6PPD in tires would be detrimental to public safety and the national economy.” Since the discovery of 6PPD-quinone, the U.S. EPA has been actively studying the threat to aquatic life. It recently announced plans to change the Toxic Substances Control Act to address the environmental risks of 6PPD-quinone. The signal to action followed outcry from a petition on behalf of several U.S.based First Nations tribes to ban 6PPD due to its proven lethality for coho salmon and other fish. The agency plans by this fall to begin gathering more information that could inform proposed regulations. David Nesseth is with ES&E Magazine. Email: david@esemag.com

Alberta’s Rainbow Lake set to be Canada’s first geothermal town By ESE Staff

he Alberta Town of Rainbow Lake is trying to become Canada’s first municipality to be powered completely by geothermal energy, and says it will capitalize on existing oil and gas infrastructure to help accomplish

the feat. The three-phase pilot project led by E2E Energy Solutions (E2E) is expected to be completed by 2028. It will utilize the company’s enhanced geothermal reservoir recovery system (EGRRS), which upgrades the temperature of saline aquifers to be commercially viable when conventional exploitation methods do not work, the Calgary-based company says. “We see the incredible potential for geothermal in Canada, especially where we can repurpose existing oil and gas infrastructure to produce renewable energy,” explained E2E Founder, Domenico Daprocida, in a statement. The three project phases will be the EGRRS pilot, the construction of a surface geothermal facility, and the design and installation of the required infrastructure within the community. E2E says its patent-pending EGRRS process targets both non-producing and producing oil and gas reservoirs for conversion into large-scale geothermal power plants capable of producing 50 to 100 megawatts. E2E says it uses a directional drilling rig to bore down and through oil and gas reservoirs to find locations where temperatures reach above 200°C. The drilling then moves horizontally towards a recovery well. Once completed, a perforated pipe is installed to create an injection well. The process is repeated several times to create what the company calls a “deep earth radiator”. “At the surface, the hot brine has passed through a separator where it flashes into steam,” explains a demonstration video from E2E. “The steam is then used to drive a turbine to generate electricity. Condensed steam and water are then treated and sent to a hydrogen electrolysis process. A concentrated brine is created after the steam is separated from the reservoir brine.” E2E says the brine can be treated and sent to a lithium extraction process. According to E2E, the process also produces recovered natural gas from the utilized reservoirs, that can be sold to market or converted into hydrogen, using energy from the geothermal plant. Rainbow Lake Mayor, Michelle Farris, said her community of about 800 residents has been studying its “vast geothermal potential” in the northwest corner of Alberta for the past six years. Rainbow Lake gained the support of the Dene Tha’ First Nation for the geothermal pilot project. Lands Department www.esemag.com @ESEMAG

Director, Fred Didzena, said the geothermal project will “provide new opportunities and economic benefits” for the region as a whole. “It will greatly contribute to the reduction of greenhouse gas emissions and a net-zero sustainable future,” Didzena announced in a statement. E2E says geothermal energy is an “underutilized” renewable energy source in Canada due to economic and technical limitations associated with conventional geothermal extraction processes.

lem outside of the set tolerances? It can be easy to picture this using pH or other parameters, but for stormwater, it’s really about the control structures. For example, a culvert that was sized and installed in the 1980s, while entirely accurate for that time frame may now be undersized based on current weather conditions. In this case, the software may find this problem. However, it is just as likely that the new tailwater (located immediately downstream from a hydraulic structure, such as a dam, spillway, bridge or culvert) conditions will be outside the purview of the software. This means the tailwater conditions are calculated but where the tailwater goes

is outside the software conditions. In this example, a human would understand the tailwater conditions and can act accordingly to offset any potential damage. Understanding the differences, pitfalls, and potential of data is critical to ensuring communities are protected from big weather events. Tools are only as good as the humans that oversee them, so the more you know about your data, the better your analytics will be. Michael Rosh is with Vancouverbased Aquatic Informatics.

Genome BC launches SAFEGUARD to expand wastewater tracking By ES&E staff

The wastewater surveillance initiative will connect experts from the BC Centre for Disease Control, the University of British Columbia, the BC Provincial Health Officer, the BC Ministry of Health, and the National Microbiology Laboratory. Dr. Natalie Prystajecky, program head for the Environmental Microbiology program at the BC Centre for Disease Control’s Public Health Laboratory, said that SAFEGUARD will help to address the “immediate challenge of characterizing circulating respiratory viruses at the community scale, which is so important at this time of year.” The pilot project is also expected to develop a wastewater preparedness toolkit for emerging threats across Canada. The toolkit will guide method validation, laboratory and analytical training, data interpretation and provide resources to put the research findings into practical use, according to Genome Canada. Over some 23 years, Genome BC has generated more than $1.3 billion to invest in more than 520 genomics research and innovation projects, including over 1,200 collaborations with partners across British Columbia and internationally.

ritish Columbia is looking to expand its wastewater surveillance with a new initiative designed to better prepare the province for future public health challenges. Dubbed SAFEGUARD by Genome BC and Genome Canada, the new project will utilize federal and provincial funding to connect a wide range of experts and target a wide range of respiratory pathogens beyond SARSCoV-2, which propelled wastewater surveillance to mainstream levels. The new three-year pilot project monitoring will integrate genomic data with epidemiological information, enabling advanced statistical modelling to guide crucial public health decision-making, explains Genome BC. “Genomics was a key tool for surveillance during the pandemic and will continue to be crucial in understanding future public health trends,” announced Dr. Bonnie Henry, Provincial Health Officer for BC, in a statement. “By leveraging the power of this technology, we aim to provide earlier detection, more precise data, and improved public health strategies for a range of pathogens, all things essential to providing effective, For more information, email: evidence-based public health guidance.” editor@esemag.com
