Two new USask studies examine chemical impact on fish from stormwater runoff By ES&E Staff

irtually no fish toxicity information exists in Canada on the effects of chemical compounds spread through stormwater runoff from rubber tires and antimicrobials used in disinfection. However, new research underway at the University of Saskatchewan intends to fill that gap. Sparked by two new grants from Fisheries and Oceans Canada worth some $600,000, the researchers will study how the chemical compounds impact rainbow trout, arctic char, westslope cutthroat trout, lake trout and fathead minnows in Saskatchewan and Alberta. “If we understand better the differences in the sensitivity across those fish species, we can conduct better risk assessments,” announced Dr. Markus Brinkmann, assistant professor in USask’s School of Environment and Sustainability, in a statement. “Another important issue is to find out the mechanisms by which the chemical kills the fish, so that we can help avoid some of those problems in the future,” he added. One of the studies will examine the impacts of 6PPD-quinone, found in rubber tires. The other will examine two antimicrobials that have emerged to replace triclosan, a product in wide use for decades that has been curtailed because of potential risks to humans and aquatic life. “The chemicals we are studying in the two projects are examples of the many emerging contaminants of concern whose safety needs to be assessed,” said co-principal investigator Dr. Markus Hecker, USask professor and Canada Research Chair in Predictive Aquatic Ecotoxicology, in an announcement. The two projects will use a new chemical hazard assessment

tool called EcoToxChip, recently developed as part of a large Genome Canada initiative to identify early toxicity indicators in, and predict the vulnerability of, target fish species. Most of the research will be conducted in the Aquatic Toxicology Research Facility at USask. An initial study on 6PPD-quinone by researchers in Washington State determined that the chemical was deadly to coho salmon at trace concentrations, and Brinkmann’s team is studying its potentially widespread ecological risk to Canadian ecosystems. “Our research is going full-throttle already, and we will have interesting findings coming out almost immediately,” said Brinkmann.

The design of the Cherry Street Stormwater facility won three significant awards for its architects.

LATEST TECHNOLOGY INCORPORATED INTO AWARD‑WINNING TORONTO Stormwater Management Facility By George Koch

n award-winning design marks an auspicious start to any project. But, when the architecture is daring and the structure must house an innovative stormwater system in a never-before-executed configuration, complete with a seven-year delay between design and construction, then clearly there will be some challenges. Construction and engineering challenges were overcome, and in November 2021 Waterfront Toronto, a tri-government organization that is stewarding Toronto’s waterfront revitalization, began final testing of its new Cherry Street Stormwater Management Facility. “The Cherry Street Stormwater Man-

agement Facility is a small piece of the City of Toronto’s large program to ensure that stormwater discharged into Lake Ontario is treated,” explains Waterfront Toronto’s Ilidio Coito. Treating such runoff water is part of an even larger environmental program in which all stormwater discharges from Toronto’s buildings, including roofs, get treated before even going into the stormwater system. Preferably, they would be put to other uses, such as irrigation. The Cherry Street facility was conceived to handle stormwater from Toronto’s West Don Lands, East Bayfront and Quayside - everything south of Lakeshore Road. “This was the first

facility of its kind. Since then, others have been built, and there are more to be built on the Port Lands,” explains Coito. The facility also sends approximately 25% of its water to the Shelbourne Common UV Treatment Facility for additional treatment and use in the fountains and water features in the park, before it is directed into Lake Ontario. The project’s complexities were significant. The facility would pump untreated water from the existing 20 m diameter, 26 m deep West Don Land Stormshaft (which also serves as a temporary surge storage function), via new underground piping, to the new, 650 m2 building.

SIDE INLET

STORMWATER is an extremely small space to handle the expected stormwater volume of up to 1,450 litres per second when compared to other stormwater management facilities. Accordingly, engineering consultant R.V. Anderson Associates Ltd. incorporated some of the latest technology into the treatment process to maximize the limited space in the building. Usually, a conventional gravity screen separator removes sediment, debris and oil from the water. Then, the second step, clarification, usually needs a lot of space, often including open-air ponds. Instead, the Cherry Street Stormwater Management Facility adopted “ballasted sand flocculation”. This is an innovative process that adds sand and hydro-cyclones to stimulate and speed up the settling of suspended solids so the clarified water can quickly flow onward, reducing the space required for clarification. The water is then subjected to standard UV light disinfection, before being pumped back to the stormshaft and out to Lake Ontario.

Lastly, recovered solids are periodically removed from the stormwater management facility and sent to a wastewater treatment facility. Coito added that “the designers felt the scale of the facility as planned was enough for the equipment. But it’s a very complex system to take care of the water. The process is complex, there are a lot of pumps, a lot of moving parts, and it’s the first facility that has all these components together.” Being situated in a showcase development zone of a world-class city, the packaging of these utilitarian tasks needed to demonstrate design excellence. The city wanted a landmark, and the Cherry Street Stormwater Management Facility was expected to display panache and sophistication, reflecting Toronto’s contemporary design and urban living values. The structure became angular, rather than cubic, and the exterior was embellished with etchings acting as rain channels running down roof and walls. Glazed openings in the façade would reveal

the system’s inner workings by day and become softly glowing features by night. The design proved sensational, winning no fewer than three significant awards for its architects, gh3* of Toronto. In 2011, the Cherry Street Stormwater Management Facility became one of eight recipients in the Canadian Architect Awards of Excellence. In 2021, Azure Magazine ranked it #3 out of 10 great designs around the world, calling the facility “a strikingly simple choreography of elements”. And, in July 2021, it received a Special Jury Award of Excellence for Inspiring Infrastructure in the Toronto Urban Design Awards, which stated: “This sublime and sculptural form creates a strong presence at a prominent trailhead well used by cyclists and celebrates a commitment to high performance in water quality.” There were some design changes along the way. “Initially the plan was to have three different shafts for the stormwater conveyance, but that would take up a lot of room along Bayside, so then the process led to combining everything into one facility, with the water being pumped, and that required a redesign,” explains Coito. In addition, “the original building design was supposed to be a concrete shell with cladding, but the costs went up, so then we went to exposed concrete.” In June 2018, Graham Group Ltd. was awarded the $22 million bid-build general construction contract, responsible for managing all the concrete, mechanical, electrical and undergrounds up to commissioning. A separate project management consultant oversaw Graham and the other consultants for the project. Graham began work almost immediately. “In brief,” explains Raymond Deasy, Graham’s project manager for the facility’s construction, “our tasks were to build the facility, build the undergrounds that take the untreated stormwater from the shaft to the facility, and back again, taking the treated water for discharge, upgrading an existing sewage pumping station within the area, and housing the upgraded control systems within the new stormwater facility.” While that sounds straightforward, continued overleaf…

STORMWATER Deasy says that “the building itself was unbelievably challenging to build.” Built entirely of cast-in-place concrete and lacking large entrances, not only construction equipment but building systems like HVAC had to be prepositioned within the footprint before the walls went up, which required additional scaffolding and bracing. During construction, as the designers realized that normal construction processes would result in concrete seams and bore joints being offset irregularly, they requested that, for aesthetic reasons, all the seams and bore joints be aligned and equally spaced. “That created another challenge because we had to customize a lot of panels on the roof,” recalls Deasy. “Those modifications took a lot of time, and to do that while shoring up over the equipment was a massive challenge.” Pouring self-levelling concrete on double-sided forms became a further one. The planned skylight was also moved from its original location. “The building

is very much design-driven, function being fit to the form, rather than form following function,” says Deasy. “We accommodated all of it as best we could.” Due to these challenges, the original completion date was extended twice to March 2021, when substantial completion was achieved. Upon substantial completion, the mechanical system’s three pumps and pipes moved far too much water for the compact treatment system to handle. While the treatment system functioned when run manually by an on-site operator, it was intended to be fully automated. Work on both issues continued over the summer and into the fall. “There was definitely frustration at not having it run as intended,” says Coito. As of early November 2021, the pumping volume and control issues had been resolved and the facility has undergone a full running test with all consultants and contractors present. From Coito’s standpoint, the more than 10-year-long process offers two les-

sons that might save time and smooth the work on similar future projects. “For this kind of project, a design-build contract that aligns those two major providers would probably have been better,” he says. More broadly, on any project involving significant innovation, all parties should recognize that added risk is intrinsic, and that things will not always go as planned. “The planning component should have incorporated a more extended commissioning period to account for the fact that a project of this nature will require extended testing and fine-tuning,” says Coito.

WASTEWATER

Open channel flow radar measurements keep working, even when temperature drops By Steve McCuskey

ost instrumentation struggles to properly monitor or control outdoor processes when temperatures drop to extreme cold conditions. Open channel flow measurements at wastewater treatment plants are no exception. The flow measurements in these channels are vital because wastewater treatment plants are required to report them to the government. Without a report, plants can receive big fines, and failed instrumentation due to freezing conditions is not a valid excuse. Every wastewater treatment plant has to measure influent and effluent and report these measurements to their regulatory agency. Many facilities make these measurements using a level measurement sensor in a flume or weir. Operators at one water resource recovery facility (WRRF) had gone to great lengths to keep instrumentation using ultrasonic technology operational through the bitter cold temperatures and snowy weather their area experiences. They had been using a flume with an ultrasonic sensor. Cold temperatures and wintry weather, however, were affecting the accuracy and reliability of their measurement. With relatively warm water flowing below the sensor and the cold air around it, frost constantly formed on the sensor face. A small amount of frost on the face of the ultrasonic sensor caused measurement errors, and during long cold stretches, excessive frost would cause sensor failures. To ensure a more reliable measurement, operators built insulated boxes around the instrumentation and added a space heater to maintain a more consistent temperature and prevent any snow or frost from building up on the sensor face. When temperatures dropped significantly, however, frost could still www.esemag.com @ESEMAG

housing over both sensors. The ultrasonic sensor still experienced the occasional failures, but the radar unit continued to work flawlessly. After the trial period, the superintendent opted to remove two old ultrasonic sensors measuring on parallel flumes and replace them with VEGAPULS C 21 radar sensors. The ultrasonic and radar sensors were similarly priced, so it was an easy decision to make the switch.

A radar level sensor and an ultrasonic transmitter are installed side-by-side to compare their performances.

occur, and when it did, the sound waves were dampened, which prevented a measurement from being made. Although this was a mostly effective solution, the ultrasonic sensors were still susceptible to the shortcomings of the technology itself. For example, operators recalibrated their ultrasonic devices in the fall, but the significant temperature drop during the winter months resulted in measurement drift since sound wave velocity changes with temperature.

A TRUE TEST IN THE COLD With the ultrasonic sensors removed, they also removed the insulated box and space heater. This made it easier to access the sensors, but it also exposed the two new radar sensors to the elements. The upcoming winter would be a true test for the reliability and accuracy of these sensors. Radar signals are immune to changing temperatures and the VEGAPULS C 21 can withstand temperatures as cold as −40°C. In February 2021, area temperatures didn’t warm above −18°C for a period of 130 hours. Night time temperatures dropped to −32°C several nights in a row. The radar sensor continued to operate without fail through it all. Throughout the cold stretch, a thick layer of frost formed on the face of the radar sensor, but it continued to output a strong, reliable measurement. The VEGAPULS C 21 is an 80 GHz radar sensor equipped with intelligent software, which work together to read through the frost and reliably make the measurement operators need.

PUMPS

Rotary lobe pumps help solve difficult biosolids pumping application requirements By Jeff Bye

perations staff at one wastewater treatment plant were initially using a reciprocating pump to move raw sludge and biosolids from primary clarifiers to the anaerobic digesters. The percentage of solids was approximately 4% by volume and, in some cases, could get as high as 6% by volume. Due to the lack of a screen, the size of the solids could not be controlled, which often caused the pump to jam. The wear on the moving parts was excessive and maintenance, requiring replacement of parts, was frequent and expensive. Spare parts were large and heavy because of the general design of the reciprocating pump. This created safety issues during handling, in addition to the cost. The plant is a relatively small one, so space is a consideration. The reciprocating pumps not only required a large footprint for their installation, but also additional room for maintenance work. The plant is managed by three people, and the frequent maintenance also resulted in schedule disruption for them, as they handle multiple tasks. Centrifugal pumps were installed as an alternative, but they presented their own set of problems. The centrifugal pumps had to be sized much larger as a result of their low efficiencies and ended up raising the cost of power. Varying solid content in the sludge also caused issues. To solve these problems, a NETZSCH Tornado T2 rotary lobe pump was installed with temporary piping, until a second pump was purchased and made operational later. After both pumps were in place, the piping was converted to a permanent arrangement. The pumps were coupled with variable frequency drives and a flow meter was added to optimize flow control. The two pumps fitted nicely on just one of the old pump pads, as they have a small footprint, which provides extra space around the installation. The first pump has been operating for more than two years with no problems. During this time, it has been periodically inspected, but did not require any maintenance nor replacement of parts. At a nearby community, the wastewater treatment plant was experiencing similar difficulties. The plant used plunger type pumps that had been rebuilt many times throughout their years of usage. They were installed in a small room which made service a struggle. The pumps were piped together with cross tie piping so that the primary and secondary sludge pumps could back each other up. This significantly reduced access to the pumps, making maintenance extremely difficult. When the primary sludge pump was again in need of a rebuild, requiring a piston, packing gland, packing, and several other components, operations staff discovered that the

price of a new NETZSCH Tornado T2 rotary lobe pump was close to the price of just the spare parts for the plunger pump. The existing primary plunger pump had to be disassembled in parts for removal so that the new rotary lobe pumps could be installed. Piping was also modified to enable better access to both of the pumps. Now, each pump can easily be inspected and serviced. The layout of the pump systems was modified to allow easy access and more space for inspection, maintenance and service. To date, the pumps have been operating without trouble and there has been no need for maintenance. Jeff Bye is with NETZSCH. For more information, contact Jason Balcerczyk, NETZSCH Canada.

Brantford WWTP earns perfect score in Grand River program By ES&E Staff

he Ontario City of Brantford earned a perfect score at a recent workshop because the effluent from its wastewater treatment system was consistently meeting a very high standard when discharged into the Grand River. The Grand River Watershed-Wide Wastewater Optimization Program workshop reviews the performance of wastewater treatment facilities on an annual basis and awards points based on defined criteria that can earn gold, silver or bronze recognition. The perfect score means that the Brantford facility, which serves nearly 100,000 residents and was commissioned in 1960, earned gold recognition. The facility employs a stream-based

The treatment plant has nine wastewater pumping stations and gravity trunk sewers within the city’s wastewater collection system. The plant’s treatment works consist of two primary clarifiers equipped with raw sludge pumps, two aeration tanks and two secondary clarifiers.

new automated bioaugmentation reduces lagoon sludge By Suzan Chin-Taylor

eeking solutions to effectively remove its lagoon sludge and reduce the associated costs, the City of Weyburn, Saskatchewan opted to implement a new automated bioaugmentation service technology from EnBiorganic Technologies on a performance trial basis. Their EBS-Di technology was attractive to Weyburn due to its plug and play readiness, zero capital expenditure and efficiency. In under 60 days, results were demonstrated in the de-sludging of the city’s wastewater lagoons, as well as elim-

The plant’s primary lagoon is 350 acres in size and was experiencing heavy sludge buildup.

ination of odour. An additional benefit to the service was the removal of fats, oils and grease (FOG) within the city’s lift stations, which had long been an issue. Impressed with the results in such a short period, Weyburn’s utility staff decided to enter an ongoing TaaS (treatment as a service) contract with Vital

Utilities and EnBiorganic to continue the work begun in the performance trial. WEYBURN’S LAGOON SYSTEM Established in 1901, Weyburn is home to a population of around 10,000. Its utility delivers water, sewer, and wastewater treatment to a customer base of

approximately 3,500. The city treats its wastewater exclusively through a lagoon system. It includes a 50-acre diversion lagoon and a 350-acre primary lagoon, consisting of two anaerobic sludge cells and a series of nine holding or polishing cells. Wastewater is held for approximately one year in the polishing cells, before the treated effluent is released to the Souris River. The plant was originally constructed in the 1960s, and expanded in 2011 with additional holding cells, enlarging its primary lagoon to the current area of 350 acres. The city’s public sewer collection system is comprised primarily of 150, 200 and 300-mm vitrified clay pipe (VCP) and PVC mainlines with a single 600-mm diameter trunk line at the connection point of its six lift stations, which feed the treatment plant. CHALLENGES Over its years of service, the lagoons have experienced heavy sludge buildup and have never been completely dredged.

Some cleaning was performed in 2006, but this only comprised of cleaning around the inlet pipes and pumping the existing sludge to the edges of the lagoon and into its corners. However, nothing was removed. The new sludge cells did receive a cleaning once after being put into service but nothing further in the way of sludge removal has been performed. Dredging of these cells was quite costly and there were issues with disposal. The material contained hydrocarbons and other contaminants that were at a level above acceptable limits for standard landfill disposal. In addition to sludge remediation and disposal, Weyburn also experienced a high degree of FOG buildup in its lift stations, that required confined space entry by operators. Normal pressure washer spray techniques could not remove the buildup, as the FOG was so heavy. Yet, regular cleaning was required to keep lift station pumps and floats in good working order.

Odour at the primary lagoon could also be an issue from time to time. Although able to meet compliance permits, Weyburn had been very close to allowable levels and wanted to stay ahead of potential issues. SOLUTION The city’s engineering department was researching alternative solutions to costly mechanical dredging and came across EnBiorganic Technologies (EBT). LA Electrical Services, operating as Vital Utilities, an EBT licensee, recommended that Weyburn consider a trial performance of EBT’s EBS-Di autonomous bioaugmentation technology. They felt strongly that this technology could help resolve Weyburn’s sludge issues, associated costs for dredging, disposal, and odour. “It was a very attractive option to consider,” says Renée Cugnet, municipal engineer for the City of Weyburn. “The solution is not mechanical and would continued overleaf…

WASTEWATER not require a large capital expenditure for equipment purchase, or a project to add it onto our treatment facility. Being non-pathogenic, and natural with no byproducts was also a key benefit.” Because Weyburn had the land space available for using facultative lagoons, constructing a mechanical treatment facility, or process, could not be justified, or considered the best route. EBS-Di combines the power of customized proprietary soil microbiology with autonomous delivery technology for all-natural, sustainable biological treatment of wastewater. The EBS-Di units measure approximately 122 cm L x 61 cm W x 91 cm H. Through a patent-pending process, they generate and activate the microbes just before they enter the wastewater system. This means the microbes are immediately ready to go to work. These microbes can perform with, or without, oxygen and because they are grown in the target water, they are already customized for the application. This translates to reduced retention time requirements. In turn, this lowers the cost per volume treated. The technology generates, activates, adapts, and dispenses EBT-microbes in one complete package. Using target water as the growth media, the generator conditions it and grows microbe cultures at a rapid pace and on a massive scale. In Weyburn’s case, the EBS-Di was programmed to produce and release 720 litres per day of active, adapted microbes, capable of growing rapidly with or without air. Because the microbes continue to grow rapidly after release, they double in population every 30 to 150 minutes. Depending primarily upon temperature, the working population continues to grow rapidly after release, as long as food and nutrients are available. If food or nutrients become depleted, the replication rate slows. If new materials do not appear soon, the microbes will enter into a cannabalistic state. If conditions do not ultimately improve, they will go into a spore state and remain inert, until favorable growth conditions return. In this manner, they are self-regulating. The generator is positioned where it can inject these microbes into the natural or manmade body of water, at a level that 20 | February 2022

grease. “Everything seemed to do a little bit, but it just wasn't really effective or continuous,” says utility manager Kim Wilkes.

The EBS-Di units generate and activate the microbes just before they enter the wastewater system.

SUCCESSFUL TRIAL RESULTS Continuous improvement in the collection system and sludge reduction was proof enough that this was a solution that Weyburn wanted to keep as part of their treatment process. Therefore, they entered a contractual service agreement with multiple extensions. The EBS-Di is provided on a TaaS contract model and did not require any capital or additional operating expenditures for the city. All service and maintenance will be provided on contract with Vital Utilities, with remote monitoring and control performed by EBT from its laboratory, now that the performance trial is successfully completed. Although the trial incorporated the deployment of two units, it was determined by EBT’s technical staff and Vital Utilities that a single unit at lift station #3 would be sufficient to achieve the desired results. Historically, EBT has found that units placed further out in the collection system are more effective and can also deliver added benefits to the overall health of the collection system. “One of the things that I am excited about is not having to have our operators enter potentially hazardous or confined spaces in the wet wells to do the cleaning and maintenance of the FOG that had always built up, and of course the associated labour costs,” says Cugnet. “But the most exciting part is not having to do mechanical dredging of the primary lagoon, or dealing with the separated sludge which we would have to store, transport, and safely dispose of. All of which is very costly and presents environmental and human risks.”

simply overwhelms the inappropriate or problem nutrients or contaminants. All that is required to set it up are a physical footprint to accommodate the equipment, and a reliable electric power source. The performance trial in Weyburn began in August 2021 and after an economic impact report and assessment, it was determined by EBT that two EBS-Di units would be utilized for the trial. One unit would be placed at primary lift station #1 and the other at lift station #3 in the western part of the city. Weyburn received some beneficial results immediately after the units went online. Within a few weeks, its collection system operators noticed that, in the lift stations where the units were set up, FOG was falling or sliding off the sides of the walls and not sticking or clumping to the pumps and floats as it always had. Because of this, operators have not had to enter the lift station for manual cleaning, whereas previously, they were required to perform this task every few weeks. Odours had disappeared in both stations as well. Prior to the trial beginning, some of the lagoons had sludge piles that were above the waterline. Approximately one month into the trial, these levels noticeably decreased, and the piles were dissipating.

PUMPS

Examining the basics of pump selection By Chadi Halahel

umps are used in virtually every facility across the world and have become a commodity and a critical piece of equipment for almost any means of production. Every sector directly, or indirectly, relies on this equipment to operate. So, it is important to understand how to select the right equipment for each application. Every application differs and with growing technology, there are dozens, if not hundreds of options to choose from for each application. However, there are some options that are much more efficient than others. Selecting the right pump will lead to energy savings, lower maintenance costs, process improvements, and a significant reduction in risk of system failure. Some of the more common types of

Each one of those pump categories can be broken up into subcategories based on the construction material and internal components. Material selection is a very important part of pump selection, as the incorrect one can heavily impact life expectancy, or even lead to instant failure. Every pump is selected based on three important factors. Without knowing them, selection will be inaccurate, and the desired results will very likely not be achieved. The required flow rate, total dynamic head, and fluid properties must be known. Pumps are used in virtually every facility across the world. Flow rate is how much fluid must flow through the system in a given period of time, typically dictated by gallons pumps are electrically driven by a motor per minute (GPM) or litres per minute or by air. Some examples of these are (LPM). horizontal mechanical seal, magnetiTotal dynamic head is the height that cally coupled, vertical, air operated dou- a fluid is to be pumped, and friction ble diaphragm and metering pumps. losses in the pipe. It is typically calculated in feet of head (FT) or PSI. Lastly, the fluid properties of the liquid being pumped need to be known. These include chemical properties, heat, concentration and specific gravity. Some processes are not purely liquid-based and contain solid matter, so applicable solid sizes need to be factored in. Due to the complexity of the equipment and the required application information, pump manufacturers need authorized distributors to be trained by them in selecting, assembling, repairing, and warehousing. This allows distributors to be able to successfully supply end users with the right equipment. Every application is unique, and each facility has different requirements, so the end user will have many options to consider. Authorized pump distributors have a better understanding of what type of pump is required for the application. They should be able to recommend options for the end user to consider for their application to operate efficiently. Chadi Halahel is with Service Filtration of Canada.

WATER

Automatic scraper strainers protect critical membrane systems By Del Williams

embrane filtration is a valuable, commonly used means of filtering water and wastewater. The challenge is that membrane systems are delicate and can be easily damaged by large particulates in the water. A pre-filtration step eliminates this risk by removing oversized suspended solids to prevent damage, eliminate unnecessary maintenance, and reduce the cost of premature membrane replacement. Among the pre-filtering options available, automatic self-cleaning scraper strainers are increasingly popular because they are affordable, require very minimal maintenance or attention, and can remove solids down to 75 microns. The strainers allow for continuous, uninterrupted flows even during blowdown cycles and can save substantial costs on maintenance and membrane replacement.

WATER TREATMENT AND MEMBRANE SYSTEMS Although various filtration methods use membranes, the most mature is pressure-driven membrane filtration, which relies on a liquid being forced through a filter membrane with a large surface area. Depending on the size and type of the particles involved, the process could be categorized as reverse osmosis, nanofiltration, ultrafiltration, or microfiltration. In general, reverse osmosis is used to produce potable water or deionized water. Nanofiltration is used in wastewater treatment, as well as by the petrochemical industry to purify gas condensates, and the chemical industry for solvent recovery. Ultrafiltration and microfiltration are increasingly used in water and wastewater treatment. Numerous industries have high water usage that can require further treatment of water, including automotive, aerospace, oil & gas extraction, refining, textiles, and pulp & paper mills. Ultrapure water, which must meet strict limits of certain constituents in the water such as suspended and dissolved solids, dissolved gases, organic carbon, and biological organisms, is utilized in electronics and pharmaceutical manufacturing processes. In industrial applications, water treatment is also vital to protect downstream equipment from fouling, scaling, corrosion, and other forms of damage or premature wear due to contaminants present in the source water. For these reasons, cooling tower and boiler feed water are generally pre-treated. Membrane filtration is also utilized to treat non-potable water sources, such as greywater and reclaimed/recycled “purple pipe” water. Because the membranes are made using thin, porous sheets of material, failing to sufficiently pre-filter any large, suspended particles from the water can cause severe damage and fouling, leading to premature replacement and unnecessary mainte24 | February 2022

nance. Most membrane filter manufacturers recommend that all influents be pre-screened from 100 to 500 microns to maintain membrane filter efficiency. Automatic scraper strainers are typically installed before the intake plenum of membrane filters, after the supply pumps. EXTENDING MEMBRANE LIFE As an alternative to sand filters, centrifugal separators and basket type strainers, automatic scraper strainers provide superior membrane protection while drastically reducing required maintenance. Automatic scraper strainers like those from Acme Engineering can provide continuous removal of suspended solids to comprehensively protect membrane systems. The units are motorized and designed to continually remove suspended particulates in industrial process water and wastewater to the specific size required, down to .003 inches (75 microns). Environmental Science & Engineering Magazine

Conventional manual strainers can become clogged quickly due to limitations in straining area. When that occurs, cleaning or media replacement is required, which increases maintenance costs. The other alternative for fine straining is automated backwash-style strainers of various designs. As particle sizes grow larger, however, large contaminants can jam up the backwash system or remain in the body of the strainer, requiring manual removal and interruption of the process flow. With the automatic scraper strainer, cleaning is accomplished by a spring-loaded blade and brush system, managed by a fully automatic control system. Four scraper brushes rotate at 8 RPM, resulting in a cleaning rate of 32 strokes per minute. The scraper brushes get into the wedge-wire slots and dislodge resistant particulates and solids. This approach enables the scraper strainers to resist clogging and fouling when faced with large solids and high solids concentration. It ensures a complete cleaning and is very effective against even organic matter “biofouling”. With this type of system, manual maintenance for cleaning is eliminated. Blowdown occurs only at the end of the intermittent scraping cycle when a valve is opened for a few seconds to remove solids from the collector area. Liquid loss is well below 1% of total flow. With so much to gain, industrial plant managers should consider selecting an automated, self-cleaning system that is essentially “set-and-forget,” where automatic scraper strainers

STORMWATER

Using ozone to treat accumulated building foundation stormwater DRAINAGE By Michael Doran

n January 1, 2022, the City of Toronto implemented a new foundation drainage policy that has far-reaching implications for development in the city. It is also a likely indication of measures to come in other cities that are also experiencing rising population growth, while their infrastructure and treatment facilities struggle to meet the demand. The policy is designed to “preserve capacity” in Toronto’s sewer systems by having building owners be responsible for the on-site treatment of groundwater and/or stormwater that accumulates in the building’s foundation. Once treated, it can then be safely discharged into the stormwater system, taking pressure off other municipal treatment infrastructure. Managing foundation drainage is 8

now an important consideration for developers, because permits for new buildings will not be approved without a detailed plan that addresses the requirements of the policy. Building engineers must determine how best to treat large and fluctuating amounts of groundwater and stormwater to meet Toronto’s new regulations. All commercial building foundations must have some form of waterproofing. In recent years, some buildings have included an enhanced non-permeable membrane to reduce the likelihood of leaks and the accumulation of groundwater and stormwater in the foundation. These waterproofing membranes are installed prior to building the foundation, are very costly, and cannot guarantee groundwater leaks will not occur in 6

the future. If leaks do arise, it is often difficult if not impossible to access the foundation exterior and remedy the source. Groundwater is typically accumulated from the foundation of the building and collected in a sump pit. This water must now be treated before it can be released into the stormwater system. Ozone treatment trains offer a cost-effective option to address this problem, as well as a stand-alone solution to meet the requirements of Toronto’s new foundation drainage policy. THE BENEFITS OF OZONE FOR FOUNDATION DRAINAGE As building engineers develop water treatment plans to comply with this new policy, there are a number of factors to continued overleaf…

STORMWATER consider in determining the best solution. The design of a site-specific treatment train incorporating the use of ozone, has resulted in a significant return on investment (ROI) for many building owners. For example, a one-to-three-year ROI has been realized simply through the reduction or elimination of municipal sewer discharge fees. Furthermore, an ozone treatment solution can be up to 10 times more cost-effective than waterproofing methods using non-permeable membranes. Ozone is recognized as a strong commercially available water disinfectant and oxidant. Ozone treatment solutions can meet all of the City of Toronto’s stormwater/groundwater discharge guidelines. Ozone is a powerful component in the treatment train for common groundwater contaminants such as manganese, zinc, volatile organic compounds, polycyclic aromatic hydrocarbons, and more. Ozone can also treat other unregulated contaminants, such as iron and iron bacteria that can build up and clog pipes over a relatively short period of time. This iron/iron bacteria buildup can rapidly restrict flow and cause damage to discharge pumps, flow meters and infrastructure. Eventually these may require costly cleaning or replacement. The treatment of iron allows for the equipment to operate at full capacity as intended. An ozone system can be installed on a small footprint, saving valuable space. This is an important consideration for developers and building engineers in an industry that pays close attention to the cost per square metre. Ozone reduces or eliminates the need for harsh chemicals in the treatment train, and can be safely produced on-site with generators that replicate the natural oxidation process. Ozone systems are low maintenance and safe to operate. They can be fully automated to monitor ozone levels and water quality, and can make adjustments as required, saving valuable operator time and costs. Ozone (O3), leaves no chemical byproducts in the water. It is produced by applying an electrical charge to oxygen (O2) molecules in water, causing them to separate and temporarily recombine with other oxygen molecules to form ozone. When ozone encounters pathogens, such 28 | February 2022

as a steward of nature. Ozone offers a chemical-free, sustainable solution that works quickly and safely to eradicate contaminants. It actually improves the water quality of receiving waterways because the treated effluent is rich in oxygen, which protects and improves watershed ecosystems. Ozone also offers water reuse and conservation opportunities that can make a significant contribution to enhancing a building’s ESG rating.

Ozone can also treat other unregulated contaminants, such as iron and iron bacteria that can build up and clog pipes over a relatively short period of time.

as bacteria and viruses, it splits the cells and eradicates those contaminants, leaving oxygen as the only byproduct. Ozone solutions provide the option to reuse treated stormwater for greywater applications. An ozone system can be designed to direct the treated stormwater for use in the building's cooling tower, water features, on-site car wash, landscape/ tree irrigation, and toilet flushing, etc. ENHANCING ESG RATINGS Another emerging but important consideration for developers is the adoption of practices that support environmental, social and governance (ESG). ESG is a set of criteria for a company’s operations that environmentally and socially conscious investors use to screen potential investments. An ozone water treatment solution that can help builders improve their ESG rating is important to their business model as a means to attract and satisfy investors, condominium boards, and even potential buyers. The environmental criteria of ESG also considers how a company performs

WHAT TO CONSIDER WHEN CHOOSING AN OZONE SYSTEM There are a number of key factors that should be considered to ensure the longterm success of your investment in an ozone water treatment solution. First and foremost, it is critical that the ozone technology is supported by a team of water professionals with in-depth knowledge of the groundwater/ stormwater treatment train from its collection in the sump pit to its release into the city infrastructure. The advanced chemistry experience required for the treatment of contaminants, along with the operational performance of equipment, is essential to provide a long-lasting, compact and reliable solution. This knowledge and experience will ensure that the project will be properly specified and the building’s regulatory guidelines will be met as expeditiously as possible. Without this regulatory approval, the ownership of the building cannot be transferred and occupancy cannot begin. These delays can cost a developer dearly. A properly specified plan will also prevent or significantly reduce the likelihood of costly change orders. The specification process should begin with a geotechnical and/or hydrological report review to identify the contaminants that need to be addressed. Once identified, the required dosage and flow rate can be determined to meet the required municipal regulations. A comprehensive design package, including a detailed system schematic, is required prior to approval of the purchase and installation of the system. Ideally, the ozone system design should include a vetted list of all auxiliary equipment included in the treatment train to ensure compatibility and optimum treatment performance.

Environmental Science & Engineering Magazine

A comprehensive submittal plan is mandatory for the city’s approval and permitting process. A properly specified, well detailed plan is instrumental in expediting this approval process. During the application review, your ozone solution partner should work with you to respond to any queries and provide design rationale and reasoning if and when necessary. Once the ozone solution is ready for installation, solid project management is crucial for success. Ozone is the most powerful component in the treatment train and requires unique knowledge and integration experience. The successful installation of an ozone system requires integration with the building's back-end monitoring technology (i.e., BACnet), carbon filters and piping, etc. Ozone, like any sophisticated technology, requires experienced professionals to engineer, install, test and monitor the solution to ensure it delivers exactly what was specified, on time and on budget. Once installed, the system needs to be

monitored over time, in real time, and working from the original commissioning to ensure that it can adjust to both seasonal and contaminant fluctuations. For example, ozone dosage must adapt automatically to address excess road salt that finds its way into the building’s sump pit through stormwater runoff. The solution partner must be prepared to work closely with all those involved in the project, including building engineers, subcontractors, developers, building owners and regulators. To ensure long-term success, your partner needs to be committed to the project

throughout the installation process and provide support when needed for the lifespan of the system. Some solutions have a 15- to 20-year life cycle. Annual water quality testing and system maintenance are also important considerations in the selection decision. As municipal regulations and contaminants change, ozone offers the potential to effectively treat the diversity of complex water issues now and in the future. Michael Doran is with Aclarus Ozone.

Community of Windigo Island uses Hollow Fibre Nanofiltration Technology By R.G.Guenther

he Windigo Island Community is a part of the Animakee Wa Zhing 37 First Nation and is located within the area known as Lake of the Woods. There are thousands of inhabited and uninhabited islands in this water body, and water quality is fairly consistent throughout the region. From a drinking perspective, the main difficulties in using this lake as a drinking water source are elevated levels of turbidity (<3 by average but >50 NTU during upset events) and dissolved organic carbon (DOC) and colour, which can cause trihalomethane (THM) concerns when chlorinated The 71 residents of Windigo Island live on a small, remote island at the southwest corner of Lake of the Woods. The closest mainland point to Windigo Island is actually in Minnesota. During the summer, most land access to and from Windigo Island is through the cartographic anomaly that is the Northwest Angle or just “The Angle” to locals. In the winter, there are established ice roads through Lake of the Woods, which makes Canadian access to the island more feasible. The island is far enough offshore to make conventional electrical/communication access impractical. There have long been issues with drinking water quality on Windigo Island. At the beginning of the project, the drinking water quality advisory in place was one of the longest in Canadian history. By virtue of its remote location, it was not practical, or reliable, to supply water treatment service and support from the mainland. Conventional treatment solutions, such a simple sand media filtration and/ or traditional small-scale reverse osmosis/nanofiltration treatment skids had proven unreliable and fallen into disuse and abandonment. The residents have historically relied on filtration with a 30 | February 2022

Drinking water treatment challenges included elevated levels of turbidity, dissolved organic carbon and colour, which can cause THM concerns when chlorinated.

sand filter and chlorination to make the lake water potable. The three aspects of the water treatment challenge that most needed to be addressed, primarily to satisfy potability requirements were: • Certified log removal credits for micro-organisms and disinfection credit. • A treatment solution that could minimize the presence of dissolved organic carbon. • Minimal treated water flow rate. Initially, a conventional ultrafiltration (UF) membrane solution was considered. Due to the technology’s references, modular design, and capability of satisfying the requirement for log removal credits, ultrafiltration seemed to be a viable solution. However, after further deliberation, it was unlikely to reduce the elevated levels of DOC/colour in the raw water to a level that would have

made the treated water compliant with THM regulations and sodium hypochlorite dosing. Instead, a dual system technology (e.g., ultrafiltration followed by nanofiltration) would have had to be considered. Along with considering different treatment solutions, the disinfection process was also a point of discussion. Due to the small system and the remote nature of Windigo Island, it made more complicated disinfection solutions, such as chloramination, or carbon dioxide, impractical. Therefore, disinfection by sodium hypochlorite, was the only practical solution. UV disinfection could be added to further extend disinfection log credits if required. What was ultimately proposed was an innovative hollow fibre nanofiltration element. Specifically, one with long, holcontinued overleaf…

low membrane fibres, which give a large filtration surface area and a membrane separation layer which, with testing, can provide documented micro-organism log-removal credit. This combined the functionality of an ultrafiltration membrane, with the dissolved constituent removal of a loose nanofiltration membrane. In essence, this was two products in one – ultrafiltration and nanofiltration. The module is identical to other ultrafiltration modules in the same form factor. The technology uses an inside-out flow path. Water enters the membranes on the inside of the hollow fibre and flows out of the individual tubes into the barrel of the module. Product water in the barrel of the module exits the top of the module through a specially manufactured end cap. The individual hollow fibres inside each module receive special processing that places a thin charged membrane separation layer on the inside of the tube. This charged surface repels dissolved organic molecules, which have a similar charge, and the membrane achieves DOC rejection by this charge repulsion phenomenon. The efficacy of this method has proven to be high. In results from pilot testing on Windigo Island with hollow fibre nanofiltration treatment it is achieving 83% rejection of DOC. In practi-

cal terms, this means that a raw water concentration of 12 mg/L DOC can be reduced to 2 mg/L, which generally would cause no THM compliance issues. As an interim solution, at the immediate crisis of getting Windigo Island off a drinking water quality advisory, it was proposed that a test-scale system be manufactured and placed in the existing treatment building, as a trial of the hollow fibre nanofiltration technology. If the system worked as intended, a treatment skid with hollow fibre nanofiltration membranes would acquire the necessary log removal credits required for making potable water from a surface source. The hollow fibre nanofiltration membrane had performed challenge testing to establish its log removal capability. It

reduced DOC from the elevated levels in the lake source water, to a level that is consistent with no compliance issues for THMs. An added benefit was that a pilotscale project could be implemented for minimal cost, as the proposed delivery would include no civil works and could be mechanically and electrically configured to work in the existing building. This effort proceeded in 2018 and was brought online in early 2019. The immediate results were transformative. Raw water turbidity and DOC were reduced to levels compliant with regulations. The membrane module had challenge test results that made it compliant with log removal credit rules. A commercial grade UV system was

included in the pilot equipment and that satisfied disinfection requirements. During commissioning, there were issues with getting the treated water storage tank clean enough to use as a backwash source for the membranes. After years of operation with just the sand filter, sediments were found in the tank. Once commissioned and operating began, there were obstacles to getting the plant operation certified. But those challenges were overcome, and Windigo Island came off the drinking water quality advisory list. The pilot-scale membrane plant was operated continuously beyond the commissioning stage. The long-term question of how a membrane solution would fare on this surface water source was answered with continuing months of operation with no degradation. The pilot system operated successfully through variations in water quality due to the changing of the seasons, and water temperature that ranged from

1°C to 19°C. The automatic cleaning system built into the pilot skid was able to maintain membrane performance without human intervention for cleaning. Over the two years of operation of the pilot skid, it only required membrane service once. This occurred when a built-in alarm sensed integrity loss, due to a pressure decay test. The required repair was minor and was completed with minimal effort. Once back online, it continued to operate successfully with no incidents until it was decommissioned in November 2021. Success of the pilot skid on Windigo Island prompted the First Nation to proceed with a design of a full-scale hollow fibre nanofiltration system, in concert with the construction of a new water treatment plant and reservoir on the island. The full-scale system was designed with significantly more treatment capacity than the pilot-scale system, which had one train with three modules in it.

The full-scale system has two trains (one fully redundant) with fourteen modules per train. It was commissioned in 2021 and is operating successfully, replicating pilot-scale results.

Improving public health in the Arctic by providing a safe water supply By Ken Johnson This article was edited from a 2016 technical paper by Thomas W. Hennessy and Jonathan M. Bressler, titled: “Improving health in the Arctic region through safe and affordable access to household running water and sewer services: an Arctic Council initiative”.

he eight Arctic nations of the circumpolar Arctic are all considered developed, but several of these countries have a wide range of water, sanitation and hygiene (WASH) infrastructure levels and are facing considerable development challenges with water and sanitation, especially in rural and remote communities. Data for the United States from June 2015 shows that, overall, approximately 99% of homes (97% for rural populations) in the entire U.S. have piped water service and close to 100% of homes, including rural homes, have piped sanitation service. However, these national estimates mask the reality for many Americans, especially those in rural communities in Alaska, where significant numbers of homes do not have piped, in-home water and sanitation services. This is despite decades of effort to supply all Americans with piped water and sanitation services in their homes. Similar problems exist for Canada, Russia and Greenland where Arctic WASH deficiencies are lost in the overall national statistics, or are lumped into an overall rural category that does not provide an understanding of regional trends or deficiencies. Although the relationship between a safe and plentiful water supply and health is well recognized, the historical focus of public health related to water service has been to prevent diarrhea-type illnesses caused by microbial contamination of drinking water. While preventing such waterborne infections remains a goal of improved access to high-quality water, access to adequate water quantity is also important for preventing “water-washed” diseases. These occur where personal sanitation practices, for example hand washing, can prevent transmission of diseases to other people. This issue has become particularly relevant during the current COVID-19 pandemic. A study of rural Alaska homes without in-home water service, showed the average water use was 5.7 litres per person per day. This amount would be categorized as a “very high health concern” because it is less than the 15 litres per person per day that is recommended for disaster response situations, such as refugee camps. Such limited access to water leads to water rationing, where the use of water for drinking and cooking is given higher priority than using water for personal hygiene. Limited access to household water is often found in homes with extreme crowding and many young children. These conditions result in increased 34 | February 2022

spreading of “water-washed” infections and help to explain the high disease rates seen in many Arctic communities. Overall, the status of water and sanitation services among Arctic communities is not well documented. Available survey information states that in-home access to cold running water ranges from 56% in Northern Greenland to over 99% in Canada. Available survey information also states that regions having water that was sometimes unsafe to drink ranged from 1% in Northern Greenland to 86% in Nunavut. Available survey information, during the period of 2010 to 2014, states that 70% of rural house units in native villages in Alaska had complete plumbing facilities, including running water provided to a sink, a flush toilet and a shower or bath. Data on waterborne infectious diseases and outbreaks, are typically reported by public health authorities in Arctic nations. Despite data limitations, overall drinking water quality in the Russian Arctic was found to be very poor, with considerable contamination by chemical and biological agents, and high rates of waterborne infectious diseases. Environmental Science & Engineering Magazine

In contrast to waterborne infectious diseases, water-washed infectious diseases are typically not reported and tracked. This makes documentation of these infections difficult because a special effort is needed to collect and analyze the rates of infection. However, several studies have shown that increased access to water and sanitation services in the Arctic is associated with reduced risk of water-washed infectious diseases. In Alaska, lower rates of hospitalization or outpatient care visits for respiratory and skin infections are associated with increasing the number of rural homes with piped water service. Infant hospitalization rates for lower respiratory tract infections (LRTI) in this population are the highest in the U.S. They are five times higher for all LRTI than for the general U.S. infant population and 11 times higher for documented pneumonia. In contrast, the rate of hospitalization for diarrhea-type infection was

comparable to the general U.S. population. This contradicting statistic is likely because safe drinking water is provided in nearly all villages, either by centralized distribution (piped) or decentralized distribution, where residents selfhaul treated water from a water station. Diarrhea infections caused by waterborne diseases are not common because this water is safe to drink, but there is not easy access to enough water for cleaning and washing. This leads to rationing of water for these purposes, and more respiratory infections. Serious bacterial infections are also water-washed diseases. A study of four Alaska villages was designed to see what would happen when these villages transitioned from self-hauled water and “honey buckets” (a dry toilet) to in-home running water and sewer service. The study showed a decrease in the number of clinic visits for diarrhea, respiratory disease and skin infections after the installation of running water

service. Although these studies indicate that there are more waterborne and water-washed infections among people living without in-home water and sanitation service, they do not provide a full view of the differences in health conditions associated with incomplete WASH services across the Arctic. Without information on the status of WASH services and health indicators related to these services, regional progress towards water goals will be hard to assess. Also, without a summary of regional data, the opportunity is missed to compare different approaches for achieving improved health for Arctic residents and to develop best practices that fit the unique challenges of these regions.

Treatment option INVENTORY will help remote, Indigenous communities improve effluent quality By Klas Ohman

any small, remote and Indigenous communities face challenges to meet established treated wastewater effluent quality standards. These communities require significant support to implement or upgrade their wastewater treatment systems to improve their wastewater effluent quality. To support them, Environment and Climate Change Canada retained Associated Engineering (AE) to complete an inventory and assessment of existing, commercially-available wastewater treatment systems. These had to meet the needs of small Canadian municipalities and remote and Indigenous communities with a population of less than 5,000 people or collecting an average of less than 2,500 m3 of wastewater influent per day. There were three main objectives of the project. The first was to better equip the federal government with reliable information on practical wastewater treatment options for small communities. The second was to provide information to support any potential future work in developing new wastewater effluent standards for these types of communities that are not currently subject to the Wastewater System Effluent Regulation, specifically north of the 54th parallel (Quebec) and in Newfoundland. The third was to share the information internally with Indigenous Services Canada and Infrastructure Canada to support their decision making and funding programs for major infrastructure projects in Indigenous communities and municipalities. AE partnered with the University of Ottawa to develop an inventory of currently-implemented, commercially-available, municipal wastewater treatment 36 | February 2022

technologies in Canada. It consists of conventional and emerging technologies and includes passive mechanical/passive stand-alone technologies, as well as potential upgrades and/or add-on technology options. AE assessed opportunities for optimizing existing wastewater treatment processes or infrastructure instead of building it brand new. AE also considered challenges that small communities have securing funding, understanding life cycle costs and financial planning, making informed decisions regarding the optimal technology, and training and retaining qualified operators. The inventory is based on information provided by owners and operators of wastewater treatment systems through the Effluent Regulatory Reporting Information systems and on the Quebec performance evaluation of municipal water treatment facilities. The project team reviewed the resil-

iency of each technology, its applicability to various climatic conditions, and potential technology combinations to meet the government’s standards. The project team also considered decentralized solutions for small residential subdivisions with flows of less than 100 m3 per day. From the review, the AE team generated fact sheets for 20 technologies, including upgrade and add-on options suitable for small, remote and Indigenous communities, especially those in harsh and very cold climatic conditions typical of northern Canada. As well, resource recovery and upgrade opportunities were included. Benchmarking capital and operating costs were important as costs vary significantly across Canada. As much as possible, case studies and information from vendors was included. Klas Ohman is with Associated Engineering. Email: ohmank@ae.ca

Water treatment plant offers growing future to northern Ontario First Nation By Craig A. Baker

or decades, many remote, northern First Nations in Ontario have struggled to develop their water treatment systems and other infrastructure. Even if they do have treatment systems, they are often not to current provincial design standards and regulations, leaving the community with boil water advisories. In recent years, the federal government has demonstrated a commitment to ending long-standing boil water advisories in Canada’s Indigenous communities, investing in the futures of these communities. When the members of Shoal Lake #40 First Nation began drawing safe water from their newly opened water treatment plant in September 2021, it marked a historic milestone for the people living on the reserve. Located on the Manitoba/ Ontario border, on the shores of Shoal Lake, the community went 24 years without safe drinking water. The construction of a new water treatment facility is about a lot more than simply clean water. This piece of life-sustaining infrastructure offers the 650 members of the Shoal Lake #40 First Nation hope for a real future. What sets Shoal Lake apart from the many other communities with similar stories is that their community became isolated on a man-made island so that nearby Winnipeg could develop its municipal water supply. In 1915, a portion of the Shoal Lake #40 reserve was expropriated by Canada to allow the City of Winnipeg to source its municipal water from Shoal Lake, located almost entirely in Ontario. In the process, the inhabitants of the reserve were forced to relocate their settlement east, where the Winnipeg water works diversion canal turned their peninsula into an island. Their community was cut off from the mainland. For a century, the political sensitivity of Winnipeg’s untreated water supply inhibited normal activities on the reserve and in 1989 many constraints were formalized under the terms of an agreement with the City of Winnipeg, the Province of Manitoba, and the Government of Canada. Under the formalized agreement, Canada finally installed pipes, pumps, and indoor plumbing on the Shoal Lake #40 reserve throughout the 1990s. However, the systems approved by Indian Affairs, as the department was named at that time, failed to meet Ontario’s drinking water quality guidelines requiring filtration of surface waters. In 1997, the community and the neighbouring community of Iskatweizaagegan First Nation suffered an outbreak of cryptosporidiosis, a potentially fatal illness caused by a single-celled intestinal parasite resistant to chlorination. As a result, a boil water advisory was issued on all the recently built 38 | February 2022

systems. It lasted 24 years. First Nations Engineering Services Ltd., a 100% Aboriginal-owned engineering firm, became part of this story in 2005, when the community contracted them to design a water treatment plant that met the standards of the day. It took three attempts—in 2007, 2012 and finally in 2019—before a budget was approved to construct the plant. The history of Shoal Lake #40 First Nation and their struggle for clean water gives context to why infrastructure is so crucial in remote Indigenous communities. The design and construction of their treatment plant and water supply is another side of the story. While the project went very smoothly, there were many times that it could have soured and gone over time and budget. Relationship management is critical to the success of projects within Indigenous communities. Firstly, many of them have decades, if not more, of experience of being overlooked and neglected by government and industry alike. It is difficult to gain their trust and easy to lose it. The involvement of multiple jurisdictions can mean many stakeholders are involved, from Indigenous Services Canada to neighbouring municipalities and two provinces, all the normal regulatory bodies, as well as contractors and sub-contractors. With everyone involved, it is important to keep in mind that ultimately the work is being done for the community. Respect for the community and its people is also paramount. It is important to connect with them and understand their traditions as well as concerns. The Shoal Lake #40 project engaged and followed the guidance and ceremonies of community elders in the identification and protection of medicinal plants, continued overleaf…

as well as the protection of sacred and culturally important sites. Presently, COVID-19 is a major complication for infrastructure projects in Indigenous communities. Each one functions independently of provincial health and safety protocols, and many have implemented their own practices, often at a higher level of requirement than the province. During the construction of the Shoal Lake #40 reserve’s water system, thanks to protocols implemented with the community and in collaboration with both Manitoba and Ontario, there was zero transmission of COVID-19 within the community over the two years of construction. This was a big win for the project and a testament to the dedication of the community’s health staff and the cooperation of the entire project team. Remoteness is another challenge with many Indigenous communities. In the case of the Shoal Lake #40 reserve, they had been detached from the mainland until early 2019. At that time, Freedom Road was completed, connecting the community to the Trans-Canada Highway. Fortunately, this allowed labour and materials to reach the community without requiring them to be transported by barge from neighbouring Iskatweizaagegan First Nation. Furthermore, it is important that projects like these do more than just build infrastructure within Indigenous communities.

The new water treatment facility offers the 650 members of the Shoal Lake #40 First Nation hope for a real future.

They also offer an opportunity to demonstrate and grow their local labour forces. Incorporating clauses into contracts that require Indigenous labour and contractors to be used is one means to accomplish this goal. However, Shoal Lake #40 First Nation took this one step further and required that all prequalified general contractors be at

least 51% Indigenous-owned. The successful general contractor was a joint venture between Kekekoziibii Development Corporation, Shoal Lake #40 First Nation’s community economic development corporation, and Sigfusson Northern. This satisfied the requirement for a 51% Indigenous-owned contractor, which was a first in Canada for a contract of this size. Thus, the water treatment plant was built by the community as much as for them. In the design of the system itself, there was opportunity to incorporate creative problem solving. Existing pumps and distribution pipes that had been built in the 1990s had to remain in use during the construction of new infrastructure. This made it possible to continue using these components and implement economical water main designs and retrofits to connect them to the new water treatment plant. For southern First Nations located near non-Indigenous communities, municipal-type service agreements, where the First Nations water and wastewater systems are connected to the neighbouring municipalities’ infrastructure, are often the most economical solution to their water supply needs. However, for remote communities, constructing a treatment facility is often the only solution. As public support grows for infrastructure in Indigenous communities meeting the same standards as their off-reserve neighbours, the future looks good. However, there are challenges to address. These include ensuring ongoing funding for the operation and maintenance of existing and new infrastructure and the rising cost of constructing these new facilities. In the past 20 years, construction costs have more than tripled for water treatment facilities, partly due to inflation and partly due to improvements in standards. This is not a barrier to project approvals right now and hopefully it remains this way long enough to see equitable access to clean drinking water throughout Canada. Operation and maintenance funding subsidies from the federal government for water systems on reserves have remained largely static for the past 30 years. There www.esemag.com @ESEMAG

have been slight improvements recently. Improved funding for water systems must be mandatory for these new and existing systems to function sustainably for their design life. With commitments to fund ongoing maintenance and continuous training of qualified local operators, the investments into Indigenous infrastructure will ensure that the com-

munities and the people living in them can thrive, grow, and build their own futures. Craig A. Baker is with First Nations Engineering Services Ltd. For more information, email: cbaker@fnesl.ca

Nunavik First Nation Community combats drainage challenges By Yves Durand, Andreanne Dumont and Isabelle Beaulac

hapmagoostui is a Cree First Nation community located at the mouth of the Great Whale River, as it flows into Hudson Bay in the province of Quebec. Their reserved land is attached to the Eeyou Istchee territorial government, but located in Nunavik territory, slightly north of the 55th parallel. The community shares this territory with their neighbouring Inuit community of Kuujjuarapik. Accessible by air and sea only, the two communities combined are home to approximately 1,800 people and are not connected to any of the southern road network. With a freezing index in Whapmagoostui of 2,800 degree below Celsius days, above zero-degree daily temperature averages occur only from June to October, and monthly precipitations are above 60 mm from June to November.

participation and apprenticeship from local personnel and resources in each step of the process. As a result, a threefold plan was drafted: 1. Design a drainage master plan. 2. Recruit and train a local construction crew. 3. Coordinate the effort and commitment from CNG, WFN and CIMA+ representatives towards a work schedule that ensured construction materials, equipment and machinery required each year were designed, purchased, shipped (and properly stored) on site by air or sealift, in time to maximize the construction period. THE DRAINAGE MASTER PLAN CIMA+ was mandated to design a new storm sewer, and an outfall pipe to the Great Whale River. This system was designed to alleviate the flooding problem next to the primary school. While proceeding, it became clear that a different plan would be required to address the water accumulation problems occurring at other places in the community. At the onset, CNG and WFN were called upon to assess the need to surface the streets of Whapmagoostui with asphalt pavement, as in the neighbouring community of Kuujjuarapik. The decision was made in favour of asphalt surfacing, and impervious surfaces runoff coefficients were used for the street surfaces in the calculation of flow rates. Because of the community’s flat land surface, it became necessary to consider the use of multiple outlets and conveyance infrastructure with greater hydraulic capacity. Piping systems were therefore added to the existing ditch system. To minimize pipe trenching depth and width, the use of detention chambers was considered to create hydraulic brakes. These underground chambers were also a means to transfer excess water to underground equipment that would otherwise create flooding above ground. It was found that these chambers also contributed to sediment control before discharge into the environment. The community’s wish was to opt for the construction of traditional paved streets with concrete curbs. This meant constructing a conventional storm sewer

They were also responsible for the planning and execution of any work related to water and sewer systems. This team was placed under the supervision of a senior site inspector from CIMA+, an experienced municipal public works coordinator. He supervised the training of the Cree construction

crew and monitored their progress in the learning process. The team worked together for six consecutive construction seasons and is now capable of planning and conducting pipe laying work as an autonomous unit.

careful planning for each activity led to an efficient on-site construction process.

DESIGN, PROCUREMENT AND SHIPPING Transportation and shipping of heavy machinery and materials to Whapmagoostui could only be done by sealifting out of the Eeyou Itschee coastal communities (Wemindji). The frequency of these transports was dependent on navigation constraints and under occasional severe sea conditions. In order to start the construction work activities as soon as the weather and the soil conditions would allow it, the necessary materials and equipment had to be shipped and stored on site, ahead of time. In some instances, this required using the last scheduled barge departure a year in advance. The importance of

CURRENT AND PROPOSED SITE DRAINAGE CONDITIONS The drainage master plan was presented to the community in April 2017, but went through some major changes as the decision to pave the streets and install concrete curbs was made some time later. Some significant parts of the plan were built between 2016 and 2018. 2016 saw the installation of a new storm sewer, connected to an outfall pipe leading to the Great Whale River, and was installed on Gakw Street. Also in 2016, a storm sewer line was built in front of the community primary school on Whapwakw Street, with the first detention chambers installed at the back. Phase 2 of the plan started in 2017. A new storm sewer pipe was installed in Whapstan Street, connecting the newly installed line in Gakw Street to the one of the few already existing storm sewers

located in the hospital sector. The final connection for the detention chambers at the back of the primary school to the storm sewer of Whapmakw Street was also completed that year. In the spring of 2018 and throughout the summer of 2018, no water accumulation was observed in the areas surrounding the primary school. The underground detention chambers were performing to the expected level to prevent surface water accumulations. Finally, in 2018, a second major storm sewer line was constructed, with the second outfall pipe leading to the Great Whale River. Since 2019, close to 5 km of storm sewer lines have been installed, officially ending the Drainage Master Plan project. This workload was coordinated with the street paving program over a planned three-year program. A last phase remains to be completed with road paving and is scheduled to begin in 2022.

is still fully employee owned. Philippe Taliana joined the team in 2012 and we opened an office in Montreal, Quebec. This expansion helped H2Flow diversify its customer base. This office has now become a major player in La Belle Provence, and Philippe is currently VP of Sales for the entire company. Another significant milestone was achieved in 2012, when H2Flow became ISO 9001 certified to better serve its customers. This certification process requires an ongoing commitment to quality as it is a big effort to maintain its compliance. Throughout these years, H2Flow kept expanding its product portfolio, signing exclusive representation agreements with Aerzen, Ovivo, Franklin Miller, Biorem, Acme, Con-VAir, Continental, Biowater and others. We are always looking out for the next great technology to bring to our marketplace. In 2013, H2Flow had an opportunity to provide its first significant export project to the country of Gabon, in Africa. This was a definite test of our in-house engineering capabilities. We designed a complete municipal WWTP for 20,000 people based on SBR technology in bolted steel tanks. Everything had to be thought of in the smallest detail. The entire system was sent in 13 shipping containers and was then built on the ground by our crew along with local labour. This was a milestone for us, especially as the whole process lasted several months, but went off without major issues. Since then, H2Flow has continued to provide many technologies and systems for export markets. In Morocco, we have provided a full system for the largest dairy and citrus producer, a system for a big fish processor and other clients. H2Flow has also worked on various mining projects in South America, as well as municipal facilities and resorts in the Caribbean. Exports represent on average 20% of the company’s revenue. As the company grew, our space needs grew along with it. By 2015, we had filled four adjacent industrial units but required even more space. In 2016, we moved to our current facility, a 20,000 square foot free standing building, equipped with three overhead cranes and outdoor storage. This facility would allow us to work on large products such www.esemag.com @ESEMAG

as containerized systems and larger DAF units. With the larger space, H2Flow continued to grow and at times it is still amazing to me how far the company has come in 30 years. To oversee this continued growth, Grace Groves, our VP of Operations, was brought on board in 2016. Today, H2Flow is a fully employee-owned company with a staff of over 50 people and offices in Toronto, Montreal and Vancouver. The company is grouped into four main departments: sales, engineering, service, and support. • The Sales group is divided between municipal sales and industrial sales, with reps focusing on certain geographic territories and market segments. • Engineering maintains in-house design services with engineers experienced in all areas of water and wastewater processes. Our designers are able to provide drawings utilizing AutoCAD and Solidworks. • The Service group specializes in start-ups, commissioning and on-site operator training. It also performs on-site repairs, troubleshooting and service contracts. We maintain our own in-house PLC programming and can provide remote monitoring. • Our Support group includes all aspects of management, HR, accounting, IT, marketing, aftermarket parts and shop work. It is thanks to the dedication of its people that H2Flow has been providing treatment solutions, exceptional customer service and building long lasting relationships with clients and customers for 30 years.

New high-tech buoy will help monitor Buffalo Pound Lake water quality By ES&E Staff

askatchewan’s Buffalo Pound Water Treatment Plant will be changing its monitoring equipment this coming summer with the purchase of a new sensor-loaded “superbuoy” that can measure elements critical to the nearby lake’s ecology, and in particular, troubleshoot algal blooms. Dr. Helen Baulch, University of Saskatchewan (USask) associate professor at the School of Environment and Sustainability, says that because Buffalo Pound Lake is so shallow, algae growth and water temperature can change quickly. The purchase of the $250,000 high-tech buoy will give plant operators the chance to view the lake’s ecology remotely, all while advancing lake science. Rapid changes such as large temperature variations between upper and lower lake levels can cause major problems for the plant that supplies potable water to Regina, Moose Jaw and nearby areas, covering about 260,000 residents. “The plant operators have seen those changes affect their operations, and our research collaboration has really helped troubleshoot and anticipate some of

those changes,” Dr. Baulch said in an announcement from USask. Dr. Baulch, also USask’s Centennial Enhancement Chair in Aquatic Ecosystem Biogeochemistry, says the buoy’s cutting-edge sensors can more accurately measure carbon dioxide that’s important to lake ecology. It also boasts cameras with telemetry so that operators can monitor the lake surface for scum. The water plant has had a less sophisticated monitoring buoy in place for some eight years, but it is in need of replacement, particularly as climate change and changes to land use “are putting unprecedented pressure on prairie aquatic systems,” Baulch noted, particularly when it comes to harmful cyanobacterial blooms. Baulch spent a few months consulting with British Columbia-based supplier Hoskin Scientific Ltd. to design elements of the new buoy, including enabling some sensors to be nestled in a metal cage under lake ice to provide year-round monitoring. For Blair Kardash, manager of laboratory and research at the water treatment plant, the partnership with Baulch underlines the value of academic-indus-

trial cooperation. The purchase of the new buoy came through a partnership between USask and the Buffalo plant’s board of directors in Regina and Moose Jaw. “We want to support Dr. Baulch’s continued research in limnology (the study of lakes) at Buffalo Pound. In doing so, we also get the benefit of having realtime monitoring for rapid changes in water quality, as well as the benefits from her long-time research on cyanobacteria,” Kardash said in a statement. The importance of sensor monitoring can also be highlighted by a situation in the spring of 2015 when thermal stratification in Buffalo Pound Lake affected water clarifiers in the plant, cutting treatment capacity in half, and leading to an emergency water restriction in Moose Jaw and Regina. Baulch and Kardash have since developed “decision trees” on how to use sensor data to adapt plant operations during periods of stratification extremes, and to advise cities to have enough water in their reservoirs to ride out any potential treatment slowdowns.

WASTEWATER

Havelock WWTP uses biological larvicide to control midge flies By Catherine Flannery

idge flies, or chironomids (chironomidae), commonly occur in wastewater treatment plants and pond systems. Managing them can be challenging, but a local Ontario Clean Water Agency (OCWA) operations team used an innovative approach to control the midge fly population at the wastewater treatment plant (WWTP) in Havelock, Ontario. The Havelock facility had been experiencing an issue with the flies in its sequential batch reactor process for some time. The red worm (larvae) that forms the midge loves the nutrient-rich conditions in a wastewater treatment plant and feeds off bacteria and sludge. The worms will eat mixed liquor (a combination of sludge and water removed from the clarifier) and once transformed into adults, they clog filters and building entrances. “The midge flies also attract birds and spiders and are a general nuisance,” says Amber Coupland, OCWA senior operations manager at the Havelock WWTP. The short life cycle of the midge fly means the population can grow quickly. Over a period of 10 days, eggs hatch

midge flies, as likely the best solution. AQUABAC xt contains a species of bacteria called bacillus thuringiensis, an approved larvicide for controlling red worms and midge flies in wastewater treatment plants and waterways. It can be poured into either the aeration basin or secondary clarifiers, depending on where the red worm problem is. It also works extremely well in UV disinfection chambers, and it is safe for fish, birds, mammals, and other life forms. In April 2021, Coupland and Robinson successfully applied to the Ministry of the Environment, Conservation and Parks for approval to conduct a trial of AQUABAC xt. The results were positive, with operations staff reporting reductions to the midge fly population at the Havelock WWTP. “It didn’t take long for staff to see a difference,” says Coupland. “We are very happy with the effectiveness of the larvicide and how quickly it has reduced the midge fly population. The plant’s sand filtration system is running more smoothly and the air lift pumps require less cleaning.” Based on the successful trial of AQUABAC xt, the product application has been added as part of the preventative maintenance for the Havelock WWTP.

into red worms and then pass through the pupa stage to become adult midge flies. With no aquatic life to feed on the midges, their life cycle runs uninterrupted, and they multiply fast. If left alone, midge flies will cause poor settling and high total suspended solids, and disrupt the bacterial environment. The mixed liquor infested by red worms can see reduced solids, stringy or clumpy sludge, and poor nutrient removal. Determined to tackle the midge fly issue at the Havelock WWTP, Brad Robinson, an operator/mechanic in OCWA’s Trent Valley Hub, began researching available methods of control.

HELPING CANADIAN WATER FIRMS reach new markets and succeed abroad

he Canadian Trade Commissioner Service (TCS) helps Canadian companies navigate the complexities of international markets. With more than 1,000 trade commissioners in more than 160 offices across Canada and around the world, the TCS offers market intelligence and an unmatched network of contacts to help Canadian companies expand into new markets and succeed abroad. Canada is a key player when it comes to clean technology and climate solutions, and the TCS can help Canadian companies operating in a variety of sectors, including water and wastewater treatment. Ann Rosen, a trade commissioner, based in Chicago, who specializes in the water/wastewater sector, says this is “one of the most important sectors in the cleantech space. There are lots of issues that need to be solved.” Rosen recently played a leading role in the TCS’s efforts at the annual Water Environment Federation’s Technical Exhibition and Conference (WEFTEC). This event is considered by many to be the world’s largest water/wastewater conference. The most recent edition of this important international trade show was held in Chicago

from October 16 – 20, 2021, followed by a virtual event called WEFTEC Online, which took place November 16 – 18. For the online event, the TCS organized a three-day Canada@WEFTEC virtual business program. Trade commissioners from 19 Canadian trade offices (10 in North America and nine in Latin America) took part in the program. The TCS’s delegation included Adolfo Quesada, a trade commissioner at the Canadian Embassy in San José, Costa Rica. Quesada has attended the Canada@WEFTEC program since 2017, including the two virtual editions in 2020 and 2021. He says his office’s participation in the program “is part of a greater effort done by key Canadian [trade offices] in Latin America” to help Canadian water tech companies find opportunities and succeed in markets abroad. “In our case, the promotion of Canadian capabilities in the water sector responds to the high need Costa Rica has in treating wastewaters,” he adds. The 2021 Canada@WEFTEC virtual business program consisted of business-to-business (B2B) meetings, an Export Café and a webinar series. This program successfully showcased Canadian cleantech capabilities in the water/wastewater sector, and generated targeted and relevant international business opportunities for the more than 115 participating Canadian water tech companies. B2B MEETINGS The TCS arranged more than 135 B2B meetings between Canadian firms and representatives from more than 60 buyers (such as utilities, industrial users, manufacturers and engineering/consulting firms) from the U.S. and Latin America, recruited by trade commissioners in those regions. Margaret Cullen is another Canadian trade commissioner who took part in the Canada@WEFTEC program. Cullen, who is based in Miami, says that thanks to WEFTEC, more than 30 Canadian companies were identified as potential clients of the Miami-Dade County Water and Sewer Department and met virtually with their energy director. EXPORT CAFÉ More than 90 meetings were held as part of the Export Café, where Canadian firms had the opportunity to meet with the 19 participating trade commissioners to discuss opportunities in their various markets. They also learned how to benefit from the Canada-United States-Mexico Agreement (CUSMA). Each market has its own needs, and through the Export Café, trade commissioners helped participating companies refine and “tighten up their pitch for specific markets,” Rosen says. Canadian businesses are therefore “better able to target their product and their marketing to different markets, because the trade commissioners can help them understand the difference between each of the markets,” she adds. Environmental Science & Engineering Magazine

WEBINAR SERIES More than 380 Canadian water tech companies attended at least one session of the nine-part webinar series. According to Rosen, the agenda was designed by the TCS to help companies get a better understanding of market trends and new technologies. Broadly speaking, the series examined two important areas of the sector. One is what industrial water/wastewater agencies or companies are looking for. The other is what water utilities are looking for. The following topics were covered: • Latin American opportunities. • Webinar for Latin American buyers on Canadian capabilities. • “Sneak Peek” overview of Canada@ WEFTEC program and update on the U.S. Infrastructure Bill (Canadian opportunities), which was co-hosted with Export Development Canada. • What’s next for utilities? The search for tomorrow’s solutions. • Industrial water report rollout – “What’s flowing in the Midwest”, which was co-hosted with the Government of

Ontario. • Digitization ops for small- and medium-sized utilities. • Cultivating opportunities in the food and beverage sector. • Fueling opportunities in the energy sector. • Forging opportunities in the manufacturing sector. The TCS is gearing up for WEFTEC 2022, which is set to take place in October in New Orleans. Initiatives like Canada@WEFTC are important because, as Rosen notes, there are a lot of challenges that need to be addressed, and Canadian While the WEFTEC 2021 tradeshow and companies have the expertise and know- attendance were about half of what they were for 2019, there was a sense of comfort that the how to provide the right solutions.

An Affordable Start to Digital Transformation for Water Utilities By Dave Johnston

ater-industry publications naturally cover the broadest and brightest promises of the digital revolution. Unfortunately, that big-picture view can often intimidate or mislead small- to medium-size utilities who interpret it as demanding a large investment to reap the benefits. However, with the right sensors and systems, utilities can start realizing the benefits of digitalization without having to make an all-or-nothing investment. Utility water resource and asset managers can use such systems to improve reliable data collection from the field, minimize distribution system breaks and non-revenue water (NRW) losses, improve asset management, and extend asset life. Financial personnel can use their data for budgeting, capital planning, asset valuation, financial performance analysis, and public outreach. Contractors can also leverage that data to project work schedules, monitor equipment status, and budget future projects. One prevalent myth is that digital technology is only for large utilities. Advancements in sensors, sensor placement, and cloud-based management platforms have made the cost, accessibility, and implementation of pressure and leak detection technologies more affordable than ever. Cloud-based solutions make data access and analytics as readily accessible as any smartphone app. Easy-to-retrofit solutions minimize the cost of installation and eliminate the need for special skilled labour. They often surprise new users in how quickly they achieve their return on investment by simply monitoring a few hydrants for operating pressure/leaks throughout the system. Using "smart” hydrants does not require full-system replacement. Only a select number of hydrants need to be equipped with sensors, and even those can be existing hydrants.

Some technologies, like Echologics, are now achieving 74% classification accuracy (i.e., 74% of events labeled as "leaks" are, in fact, leaks). New technologies in development are scheduled to improve that to 93% classification. Leak-noise-correlation technology has advanced so far in recent years, that even small installations can benefit enough from early leak detection and resulting savings to pay for the investment in as little as a year.

Having affordable sensor and communication configurations that can be added to existing hydrants in an hour or two, without excavation and without compromising functionality, is an important consideration for easy retrofit applications.

managers greater ability to understand what is happening than each individual reading does. For example, acoustic leak detection can identify and track slow-growing leaks that start small, while pressure monitoring does a better job of detecting sudden bursts. Analyzed together, they can help water distribution utilities have a better appreciation and understanding of system changes and of developing problems over time. Be sure to incorporate pressure sensing that can automatically capture the detailed data needed to document transient pressure-spike problems when they suddenly occur. Having the status of all sensors monitored by a network operations centre, with individual readings readily available through a web-accessible dashboard, gives utilities 24/7 confidence in system visibility. This can be done in-house or some manufacturers will offer to oversee for you. This provides the opportunity to monitor suspicious signals, tend to small leaks proactively before they become big problems, and respond to pipe-burst emergencies before they trigger boil water advisories. It also enables early identification of NRW losses and managing of aging infrastructure assets more cost-effectively through the best combinations of leak detection and monitoring, pressure relief valve operation, and advanced metering infrastructure.

Being able to access a network platform from any web-accessible device enables all utility employees to benefit from timely data being collected.

Even with the right hardware, it is important to know how to configure it for optimal insight into distribution system performance. Consulting a knowledgeable supplier who is experienced with factors such as system age, water main materials, elevation changes, and operating pressure profiles can all impact ideal sensor placement for the best insights into systemwide performance.

Predictive stormwater models help protect Lethbridge’s infrastructure By Adam McDonald

n recent years, the City of Lethbridge has experienced several significant rainfall events, resulting in roadway flooding and damage to infrastructure in Alberta’s fourth largest city. Extreme rain events in 2020 further highlighted areas prone to flooding and the need for operational improvements to the city’s stormwater management system. The city’s stormwater infrastructure consists of approximately 465 kilometres of stormwater pipe, 6,000 stormwater manholes, and many stormwater management facilities. To better understand and help plan for improvements to their stormwater management system, the city wanted to develop a stormwater model of the system, and retained Associated Engineering (AE) to undertake this work. It sought the ability to evaluate their stormwater management system against design rainfall events to determine the conditions contributing to flooding. It also wanted to be able to confirm drainage capacities in new areas being developed, and where new areas will be connecting to the existing system. The AE team’s tasks included data collection and review, development of a geographic information system (GIS) data model and model development templates, data quality control, design rainfall event selection and design, climate change rainfall forecast, development of existing system one-dimension by one-dimension drainage models, quality assurance and quality control reviews, existing system analysis and risk assessment, development of improvement concepts for five top-ranked locations, cost estimates and reporting. Model files are large in scope and incorporate all of the drainage infrastructure. As a result, the full City of Lethbridge model was divided into separate models to streamline model run times. The development of detailed stormwater management models using traditional methods is an extremely labour-intensive exercise. AE’s approach uses GIS tools and programming to facilitate development of key parts of the model. AE’s team developed one-dimension by one-dimension (1D-1D), dual drainage models of the city’s drainage system, analyzing stormwater flow in the storm sewer system as well as surface drainage. The models needed to cover all of Lethbridge and be sufficiently detailed to predict flooding due to minor system (e.g., gutters, catch basins, and storm sewers) surcharge and major system flows (e.g., streets, streams, channels, and ponds). The model development required significant data analysis and pre-processing to verify data. As a value-added exercise, AE committed to additional data input, feature digitization, and GIS quality control. The project team developed automated custom queries for 54 | February 2022

Area map, including the city-wide stormwater models.

GIS data processing, comparing the data by proximity to help identify and flag any issues. Any missing data was interpolated and flagged for future identification. Throughout the project, the team looked for opportunities to further refine the standardized approach to model building and made significant improvements to the GIS programming that is used to streamline the process. The model results were validated against anecdotal information of historical flooding, matched known flooding locations, and, in some cases, the results of other stormwater models, which provided confidence in the accuracy of results produced. Climate change adaptation was a key consideration on the project. The team provided the city with models that incorporate the design rain events, as well as historical return frequency events, and forecasted climate change events. The forecasted climate change rainfall events will enable Lethbridge to quantify the requirements to manage current and future flood risk affected by climate change impacts. AE also identified five areas for improvements to mitigate flooding. To assist the city with prioritizing improvements, they recommended that the city work with stakeholders to develop a customized definition of the preferred level of service for each area, based on a triple bottom line approach. The existing system models should then be used to develop a master drainage plan that takes a holistic look at flood risk and mitigation plans and thus inform investment in infrastructure and capital expenditures. The project is in its final stages, and is scheduled to be complete early this year. Adam McDonald, is with Associated Engineering.

Overcoming water treatment disinfection challenges from elevated ammonia levels By Tony Kobilnyk

arying ammonia concentrations in the water supply are a constant challenge for the small village of Creelman, Saskatchewan, which is home to about 120 residents. For decades, ammonia has prevented the water treatment plant’s chlorine system from consistently achieving primary disinfection and sufficient free chlorine in the distribution system. The situation has led to many boil water advisories, at times lasting several months, until the ammonia concentration in the source water drops to a level that the plant can cope with. Chlorine disinfection can become difficult when ammonia concentration is as low as 0.2 mg/L. At this level, ammonia begins reacting with chlorine to form chloramines, which can also cause taste and odour issues. Though chloramines do provide disinfection, much more contact time is required, so it is not recommended by the Saskatchewan Water Security Agency (WSA) that this method be used for primary disinfection. The situation in Creelman escalated in 2017, when ammonia levels in the pond that provides the community’s potable water increased to as much as 2.5 mg/L during the winter months. Breakpoint, or super-chlorination, was one way to overcome the high ammonia level. But, the process greatly increases chlorine consumption and operating costs and could cause the plant to exceed the maximum use level (MUL) of the chemical as set by NSF/ANSI Standard 60. Randy Schatz, of Element Water Systems, suggested a more efficient and cost-effective alternative to chlorine for the Creelman water treatment plant’s (WTP) disinfection process. Schatz proposed the UV Pure Hallett 1000 system, an advanced, low-maintenance unit that is EPA-certified to provide a powerful UV dose of 186 mJ/cm2 and achieve 4-log inactivation of viruses, including adenovirus. The Hallett systems could effectively provide primary disinfection of the source water regardless of the ammonia concentration and eliminate the need for breakpoint chlorination and the associated risk of MUL exceedance. Chloramines would still form once chlorine is added for secondary disinfection, but the method is acceptable by the WSA as long as the total chlorine level in the distribution system is maintained at no less than 0.5 mg/L. According to one government agency, chloramines may also offer some advantages over chlorine since they provide longer lasting disinfection in the distribution system and form fewer potentially harmful disinfection byproducts than chlorine. Schatz worked collaboratively with the community’s plant operator, the project consultant, KGS Group in Regina, and the WSA to obtain the required approvals and to design a multi-unit Hallett 1000 system that would align with the

plant’s treatment process and fit the available space. Once the approvals were in place, Schatz and his team installed and commissioned four EPA-certified Hallett 1000 systems at the Creelman WTP, capable of providing a total treatment capacity of up to 113.5 L/min. Hallett systems are suitable for small- and medium-sized water and wastewater treatment systems, since they incorporate several innovative design features that help minimize oversight and maintenance requirements, increase affordability, and enhance reliability. One major advantage is new lamp and ballast technology that enables the UV lamps in the Hallett systems to perform up to a dozen on/off cycles per day. This is especially important for a small system like Creelman’s, where water is treated intermittently. Their Hallett 1000 systems are configured to operate only when the plant’s filter system is running. Otherwise, the Environmental Science & Engineering Magazine

UV system is shut down, which reduces electricity consumption and extends lamp life. Each Hallett system is equipped with dual UV lamps that are mounted vertically in air, so lamp changes can be performed quickly and without the need to drain the system. The Crossfire system also adds elliptical reflectors that enable UV light energy to be redirected back through the water column, eliminating shadowing and targeting pathogens from every angle. An automatic cleaning system prevents scaling and biofouling of the quartz sleeve and dramatically extends the intervals between manual cleanings. The operator of the Creelman WTP reported that even after a year of operation, the automatic cleaning system maintained the quartz sleeves in pristine condition and no manual cleanings were required. Innovative sensor technology also provides a reliable and affordable way to ensure water quality. Each system is equipped with four integrated sensors

that continually monitor UV transmittance (UVT) and UV intensity (UVI), which helps budget-conscious water plants avoid purchasing external UV sensors. Performance data can be remotely monitored by the operator in real time, thanks to 4-20 mA/Modbus output capabilities that are an optional feature. Like the UV lamps, the sensors are mounted in air, which prevents fouling, the need for frequent cleaning and monthly calibration. If the sensors detect that UVT or UVI measurements are not within specified parameters, the system will shut down until the operator can correct the issue and restart the system.

Regulating and removing PFOA and PFOS to protect public health By Saleha Kuzniewski

mong per- and polyfluoroalkyl substances (PFAS), only perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) have been sufficiently studied to develop regulations in Canada. Chemicals are regulated in Canada under the Canadian Environment Protection Act, 1999 (CEPA, 1999). CEPA, 1999 provides the legislative foundation for environmental and health protection in Canada. It gives authority to the Minister of Health to regulate toxic substances, including PFOA and PFOS. Toxic substances are defined in CEPA, 1999 in terms of the risks they pose to human or environmental health. Part 5, Section 64 of CEPA, 1999 says that a substance is toxic if it enters the environment in a high concentration, or under the conditions that it may have a harmful effect on the environment, or may constitute a danger to the environment or human health. To assess whether a substance is toxic, information is collected in regard to the health effects from exposure to the substance as specified in Part 5, Section 68 of CEPA, 1999. Weight of evidence and precautionary principles are applied when conducting and interpreting results from the assessment of the substance and from reviews of the decisions from another jurisdiction, as specified in Part 5, Section 76.1, and substances that are toxic are added by the Minister of Health to the list of toxic substances called Schedule 1. In 2006, Environment Canada and Health Canada concluded from their studies that while PFOS were not a health concern at the exposure levels at that time, they declared PFOS and its salts to be environmentally toxic and added these to Schedule 1 of CEPA, 1999. Two years later, in 2008, the Canadian industry shifted from using PFOA and PFOS to other PFAS as alternatives. This move 58 | February 2022

was on par with the PFOA Stewardship Program launched by the U.S. EPA and eight major companies in 2006 to reduce the emission and products’ content of PFOA by 95% by 2010 and to completely eliminate PFOA content by 2015. In 2018, Health Canada set the maximum acceptable concentration (MAC) in drinking water at 0.2 µg per litre for both PFOS and PFOA. Health Canada also recommends the use of activated carbon filters and reverse osmosis (RO) systems to treat well and tap water and to test the water for concentrations of PFAS prior to, and after installing the treatment. As both PFOS and PFOA could be found together in water, testing is not straightforward. Therefore, Health Canada has published an equation for this situation: the sum of the concentration of PFOS in water divided by the MAC for PFOS and the concentration of PFOA in water divided by the MAC for PFOA. The MAC here is a fixed value: 0.2 µg per

litre, as mentioned above. For testing the concentrations of PFAS other than PFOS and PFOA, Health Canada has published a table on Drinking Water Screening Values (DWSV). This table consists of the DWSVs for a number of PFAS and is available in the publication by Health Canada Water Talk – Perfluoroalkylated substances in drinking water, 2019. According to this, while the DWSV values are based on limited review of the existing science and not peer-reviewed, the table is based on assessment done by other jurisdictions in Canada. There is no risk from the drinking water if it has a concentration of a PFAS below the DWSV. If the concentration is higher, then the above-mentioned treatment options are recommended. Activated carbon filtration, one of the technologies recommended by Health Canada for removing PFOA and PFOS from drinking water, is effective as it is highly porous and its large surface area allows chemicals to adsorb to it. Adsorp-

tion is a chemical process in which a substance accumulates at the interface of the liquid and solid phases. The activated carbon in the commercially sold filters is in the form of granulated activated carbon (GAC). The depth of the carbon bed and type of carbon used to make the GAC, the types of PFAS to be removed from the water, and the organic contents in the water are factors that affect the performance of the GAC filters. GAC filters are more effective in removing long-chain PFAS such as PFOA and PFOS relative to short-chain PFAS. The other technology recommended by Health Canada is reverse osmosis (RO). It uses a semi-permeable membrane to separate contaminants from the water. Specifically, the contaminants stay on top of the filter and the clean water moves through. The pressure applied and the pore size of the membrane are factors that affect the performance of RO filters to remove the contaminants from the water. According to the U.S. EPA, RO filters are more than 90% effective in removing a range of PFAS, including PFOA and PFOS. There are a number of GAC and RO filters sold commercially that are capable of removing PFOA and PFOS and can be installed on household taps. However, these GAC and RO certified filters for removing PFOA and PFOS can be expensive. Also, like all water filters, they need to be changed periodically. Depending on the types of filters suited for the specific drinking water issues, installation might not be simple. On the other hand, not all cheaper filters have the capability to remove PFOA and PFOS from drinking water. Although GAC and RO filters could remove PFOA and PFOS from drinking water, this is not a complete solution. These chemicals are still in the water source, so there is an urgent need to remove them due to their toxicity and environmental health risks. There are companies that offer solutions to municipal drinking water providers and also to airports and military bases for PFAS removal from water sources. In addition to filtration, there are also other physical, chemical and biological methods. www.esemag.com @ESEMAG

Soil excavation and disposal transfer the PFAS to another location such as a landfill to avoid long-term exposure and liabilities. The PFAS at a landfill could eventually leach into the groundwater, and contaminate water supplies, becoming another long-term liability. In soil capping, contaminated soil is contained in a geomembrane and a sand and gravel layer is added on top,

followed by a vegetative layer on the surface. The capped area may face limitations to property redevelopment, require engineering controls, and longterm monitoring of the groundwater. Bioremediation is a biological method and several micro-organisms have been identified for their capability to reduce the concentrations of PFAS in the envicontinued overleaf…

WATER ronment. This includes the micro-organism Acidomicrobium sp. strain A6, which is capable of removing up to 60% of 100 mg per litre PFOA and PFOS in about three months. Chemical methods have proven to be effective in the removal of PFAS including for PFOA and PFOS and these methods work on the principle of chemical sorption using activated carbon as a binding agent. Specifically, the binding agent is injected into the contaminated soil and the PFAS sorb onto the binding agent. An example of this chemical technology is the use of colloidal activated carbon as a sorbing agent for PFAS as discussed in an article in the June 2021 issue of Environmental Science & Engineering Magazine by Ryan Moore from REGENESIS. They are now using PlumeStop which, according to the article is basically activated carbon created by milling coconut fibre activated charcoal to 1 – 2 µm in size and then suspending it in a substance to prevent it from clumping.

ing site located near a fire training facility. After a year of using PlumeStop, PFOA and PFOS were below detection limit. The use of nanomaterials in catalytic processes is another technology for treating PFAS-contaminated water. This was also discussed on Environmental Science & Engineering Magazine's website on August 9, 2021. As PFAS are negatively charged in water, they can be removed by the positively charged anion in an electrochemical environment. Surface-active foam fractionation is another technology proven to remove PFOA from groundwater and its effectiveness depends on the adsorption coefficient at the gas-liquid interface. PFAS are prevalent in water across Canada. In February 2021, the drinking water intake area connected to Lake Memphremagog in Quebec reported 14 ng per litre PFAS. A map of PFAS hotspots in Canada, based on several sources including the Environment and Climate Change Canada report, showed that PFAS are widespread.

The median sum of PFAS was 8.9 ng per litre for Waterford River (NL), 41 ng per litre for Hamilton Harbour (ON) and 62 ng per litre for Mill Creek (B.C.). While these values are lower than the MAC for PFOA and PFOS (0.2 µg per litre), it is still concerning considering that these chemicals are widespread in blood samples taken from people and they are also found in other animals. Additionally, the concentrations detected indicate that these chemicals possibly bioaccumulate in high trophic organisms. Legislative regulations and mitigation technologies for any toxic chemical go together and must be progressive to protect health and the environment. Replacement chemicals for PFAS include GenX, perfluorobutane sulfonic acid, and other shorter chain-length PFAS telomeric substances. However, we do not know yet if these PFAS-replacement chemicals bioaccumulate in high trophic organisms. Furthermore, their toxicity and effects on the environment due to their breakdown products are a

concern and, while this is being studied, it is also imperative to be ready with effective and practical technologies to prevent their contamination of water supplies. Recommendation for the assessment of PFAS-replacement chemicals was also made by a number of Canadian organizations, including the Canadian Environment Law Association in their reply to the Notice of Intent under CEPA, 1999 to address the broad class of PFAS published in the Canada Gazette in April 2021. These organizations also requested a shorter timeline for the release of the Government of Canada’s State of the PFAS report. The longer we wait for stakeholders to take action, the more PFAS will spread everywhere, leading to decreased productivity due to health issues, and negative effects on the economy.

Studying cyanobacterial blooms, nutrients and OXYGEN in a phosphorus-rich lake By Robert Bowen

ictoria, British Columbia experienced several record-breaking weather events last year. They included a heat dome, with temperatures reaching over 40°C for several days, a prolonged drought with no precipitation for 51 consecutive days, the lowest atmospheric pressure ever recorded, with associated storms, and a number of atmospheric rivers causing widespread flooding in November, with a rainfall total for the month of 316 mm. The impact of these atmospheric features tests the resilience of our complex freshwater ecosystems as they try to adjust to unusual physical, chemical and biological forcing. In urban areas, these forces add to the already significant human-induced impacts caused by urbanization, agricultural practices, and the modifications of hydrology as water moves through altered landscapes. To be able to examine the impact of such forcing, it is important to develop an understanding of the complex nature of interacting systems and exhibited patterns that govern behaviour. To this end, an ongoing multi-year water quality study has been conducted at Swan Lake, a nine-hectare shallow eutrophic/hypereutrophic lake located within the municipality of Saanich near Victoria, B.C. Swan Lake is far from existing in a steady state, as it undergoes changes that vary over many different time scales, including minute by minute, diurnally, monthly and interannually. With the onset of the June 2021 heat dome, water temperature values rose to near 30°C. Figure 1 shows one of the lake sites displaying a total of six years of surface and bottom water temperature data. During this period, winds were relatively calm and skies were generally clear. It was at this time that a lake-wide cyanobacterial bloom, dominated by Dolichospermum (formerly known as Anabaena), turned the lake to a bright green hue. 62 | February 2022

The pH values peaked during the heat dome to their highest yearly value of 9.77, a full

Of note during this event, the total phosphorus (TP), a nutrient in abundance at this lake (typically in the order of 300 µg/L) saw a sharp decline in concentrations that corresponded with the rise of the bloom. Water samples were taken during this bloom and concentrations of TP and nitrogen were plotted along with profile data of DO in Figure 3. The Dolichospermum bloom is denoted continued overleaf…

WATER by the elevated DO concentrations in the surface and near surface waters. As the bloom developed, the anoxic layer at the lake bottom expanded, creating an abrupt DO gradient. Comparing the progression of the bloom as indicated by the DO contours, note the TP concentration began to diminish with a slight lag time. As the Dolichospermum produced glucose and oxygen as a byproduct of photosynthesis, phosphorus was also consumed. To better understand the dynamics of phosphorus migration, vectors were mapped onto the contours to indicate gradients or the flow of phosphorus in the water column. Arrows point in the direction of higher concentrations and the size of the arrow indicates the relative magnitude of the gradient. Note the downward migration of TP as the bloom progressed in time, suggesting that as the Dolichospermum die off and drop to the bottom, the TP is taken with it. The slices to the right of the contour plots show an inverse relationship between DO and TP until the peak DO concentration. Specialized cells within the Dolichospermum colony called heterocysts have the ability to fix nitrogen from their surrounding environment (see Figure

2). These cells share this nutrient with thetic cells. In this example, as the TP adjacent cells in exchange for glucose concentration is drawn down through produced by the colony’s photosyn- metabolic processes, it appears that the Dolichospermum colonies ramp up their production of nitrogen to supply their photosynthetic nutrient requirements to produce glucose. The bloom lasted about 26 days, with its most intense peak occurring in the last week of June, during the highest FOR ALL YOUR CONFINED SPACE ENTRY REQUIREMENTS: air temperature values of the year.

high as 1.35 mg/L. These concentrations were more than four times that of the spring surface waters. Benthic bacteria at this interface convert organic phosphorus found within dead plant and animal material back into inorganic phosphorus through decomposition. It is this form of phosphorus that is readily available for plant uptake, completing the aquatic phosphorus cycle. From an aquatic health perspective, phosphorus in freshwater lakes has been referred to as a “biochemical engine”. As there is no phosphorus in the atmosphere, phosphorus enters the aquatic environment either through external loading via inflow creeks and rivers, surface runoff, groundwater movement, or through internal loading due to legacy phosphorus accumulated in benthic sediments. For the biochemical engine analogy, the external loading is like the engine’s power supply and the internal loading is like the engine’s battery. Swan Lake has very high values of phosphorus both from external and internal loading and falls within the trophic status of eutrophic to hypereutrophic. The lake exhibits significant oscillations in DO concentrations, lake-wide algal blooms and, in the past, hypoxic fish kills. With each successive year of field observations and data collections, patterns are emerging, resulting in a greater understanding of the processes at work within this nutrient-rich lake. As this lake is a nature sanctuary, the goal to improve water quality is comparatively broad and not specifically targeted to human activities such as swimming, fishing, or even potable water. Presently, interventions are being considered to address cyanobacterial blooms and their potential to form hazardous cyanotoxins. One such intervention is the use of ultrasonic frequencies to inhibit the vertical migration of cyanobacteria as they optimize their position in the water column for photosynthesis. Both Aphanizomenon flos-aquae (AFA) and Dolichospermum, common species at Swan Lake, regulate their position in the water column by inflating or ballasting vesicles. This diurnal migration was observed in the data obtained from the 2018 study at Swan Lake using ASL Environmental Sciences’ acoustic www.esemag.com @ESEMAG

zooplankton fish profile (AZFP). This instrument uses acoustic beams to examine backscatter within the water column. The AFA species was verified by net samples and drop down camera images. The use of ultrasonic frequencies (such as those used by LG Sonic) in many settings has been effective at interrupting this vertical migration, thereby reducing the cyanobacteria’s ability to increase to bloom status. Adopting this technique at Swan Lake may improve the significant algal problems typically experienced each summer and discussions are ongoing to determine its possible trial use in an isolated area of the lake to compare cyanobacte-

rial growth with other parts of the lake. This top-down strategy of addressing the cyanobacterial issues directly is only one part of the interventions needed to improve water quality at Swan Lake. Further research is needed to consider bottom-up strategies that would reduce the high levels of phosphorus within the lake. Funding for this water quality monitoring program was provided by Swan Lake Christmas Hill Nature Sanctuary. Robert Bowen is with Diversified Scientific Solutions.

GROUNDWATER

Developing an action plan for remediation and management of PFAS in groundwater By James M. Tinjum and Elliot Draxler

he City of Rhinelander is a rural community located in Northern Wisconsin with a population of just under 8,000. In 2019, it shut down two of its five municipal water wells because concentrations of per- and polyfluoroalkyl substances (PFAS) were detected above EPA health advisory concentrations. The temporary decommissioning of the two wells has placed the city at risk of not meeting local water demand. A better understanding is needed of how different PFAS compounds migrate within and between surficial source areas, the vadose zone, and groundwater. These transport patterns are complex because they depend on PFAS type (e.g., branched versus unbranched), degree of saturation and sorptive compounds in the subsurface, and environmental chemistry. Understanding these fate and transport mechanisms will help guide the development of standards for the protection of groundwater resources. Geochemical "fingerprinting" may enable regulators and impacted communities to not only identify primary and secondary sources based upon the relative concentrations of various PFAS compounds, but also develop an action plan to remediate these sources. Fate and transport models are needed to increase the “know-how” on how to reduce the spread of PFAS away from source areas, to reduce the total mass of PFAS circulating in drinking water well source zones, and to update wellhead protection plans. BACKGROUND Hu et al. (2016) reported that drinking water supplies for six million U.S. residents exceed the EPA’s lifetime health advisory (70 ng/L) for perfluorooctanesulfonic acid (PFOS) and perfluorooctanoic acid (PFOA).

Other PFAS compounds, including PFOS and PFOA, were detected at concentrations of 79.6 and 25.5 ppt, respectively. Well

No. 7 was shut down to protect the health and safety of residents. Soon after, adjacent Well No. 8 was also decommissioned after testing showed concentrations of PFHxS reaching a peak value of 95.7 ppt. In addition, the local health department issued a health advisory for continued overleaf…

are shown in Figure 2. The spider plots display normalized concentrations for comparison of analytes on a percentage basis. It is expected that areas affected by the same PFAS source would display a relatively similar spider plot, with some spatial variation. There is similarity between the spider plot shapes of the landfill leachate wells (Figure 2a), with the main detection being PFOA. The spider plot shapes of Municipal Wells No. 4, 5, and 6 also appear similar, forming a bowtie-like shape that shows increased concentrations of PFOS, PFOA, PFHxA and PFHpA (Figure 2b). Municipal Wells No. 7 and 8 display a different signature, with a sharp peak towards PFHxS (Figure 2c). The spider plot shape of Well No. 7 has evolved, showing increased concentrations of PFOA with time. This could be due to several factors including evolution of a contaminant plume, mixing of plumes from two source areas, or natural attenuation. More data is required to form a valid conclusion.

This initial geochemical fingerprinting analysis characterizes the area into three zones, separated by distinctly different geochemical fingerprints. The first zone comprises the closed legacy landfill, where spider plots show a strong peak towards PFOA. The second zone resembles a bowtie shape on the spider diagram and encompasses Wells No. 4, 5, and 6. Signatures from other wells display a similar geochemical fingerprint. These are expected to be influenced by a similar PFAS compound. The third zone displays a geochemical signature with a peak towards PFHxS. This signature is present on testing from Municipal Wells No. 7 and 8 along with other wells and the Crescent Spring. It is expected that the wells in each zone are impacted by similar source areas or compounds. As the science evolves, geochemical fingerprinting may be useful in determining the type of contamination at the source. It is recommended that additional study be completed to link a source type based on geochemical fin-

gerprints. This study would warrant further and more extensive sampling to provide valid and accurate results. Finally, unsaturated zone and groundwater flow and transport modelling would help define flow paths from suspected source area(s) to the municipal wells. Models can integrate the geophysical and chemical data and allow for the testing of hypotheses about the transport, partitioning, and fate of the PFAS from the land surface through the vadose zone to the water table to the municipal wells. This type of modelling would help relate the observations from potential source zones (sampled via suction lysimeters) with PFAS concentration measured in the wells to better understand partitioning of different PFAS compounds. A step-loading model can support the interpretation of the spider plots as would the calibration and analyses of the unsaturated zone and groundwater flow and transport modelling. These types of analyses can capture dilution, retardation, continued overleaf…

GROUNDWATER biodegradation, and dispersion of the individual analytes (Newell et al. 2002). The monitoring of the response over multiple seasons would allow us to extrapolate the potential depletion (i.e., non-linear response) of the source and identify environmental and climate risk factors that are required for decision support tools. WHAT’S NEXT? To empower the community through education and outreach on PFAS research, Water Action Team Rhinelander (WATR) has encouraged the following: • Research to understand PFAS compounds in the environment and impacts to the environment; • Elected officials and government agencies to develop solution-oriented policies; and • Industry development of remediation and treatment solutions. These solutions benefit not only Rhinelander, but other impacted communities. By implementing this citizen external advisory group, WATR has incorporated environmental justice and health equity into their public engagement efforts, in addition to building partnerships with a variety of stakeholders and enhancing collaboration with state and federal agencies. WATR has already had monthly technical forums and encouraged public comment through a Facebook page and a city-wide survey. Ongoing actions that would stem from this effort would include developing PFAS risk communication infrastructure, long-term water supply solutions, new tools to address PFAS-contaminated sites, and protocols to effectively inform, educate, and engage the public about PFAS. Evolving technical content is included in the continuing engineering education program at UW–Madison, including a short course on Solid Waste Landfill Design, which is offered early each spring. James M. Tinjum and Elliot Draxler are with the University of Wisconsin– Madison. Email: jmtinjum@wisc.edu, edraxler@wisc.edu. (References are available on request)

Wastewater data filling void as Canada’s PCR tests for COVID-19 decline By ES&E Staff

hile many Canadians continue to check daily case counts for COVID-19, some experts suggest that keeping tighter tabs on wastewater surveillance trends could paint a fuller picture, particularly as PCR testing becomes more and more limited. The limited testing, now often reserved for high-risk and essential workers, is creating an underreporting of new virus cases that will only get larger as some jurisdictions, such as Ontario schools, suggest moving away entirely from reporting daily case counts. While many health units in Canada’s urban areas already receive wastewater data, not as many are posting the new data online as public information. That may soon change, say officials with units such as Public Health Sudbury and Districts, as they look to fill the gap emerging from limited clinical tests. “It does have the potential of being able to indicate trends where just given the provincial testing strategy at this time, may not be picking it up because of the numbers that are being involved,” Burgess Hawkins, manager of health protection at the health unit in Sudbury, told CBC News. As of August 2021, all 34 Ontario public health units had joined the $12 million province-wide Wastewater Surveillance Initiative, with approximately 160 sampling locations covering over 80% of Ontarians. Sudbury health officials currently get wastewater data through a project involving the Health Sciences North Research Institute and Laurentian University. They said they are working on ways that make sense to provide wastewater data online to the public. They do want to remind citizens, however, that the wastewater data only essentially shows whether

COVID-19 cases are on the verge of rising or declining, which may not satisfy some of the public’s more immediate thirst for finely detailed data. Wastewater data in many regions is also revealing the quickly changing landscape from the Delta variant of COVID-19 to the Omicron variant becoming the primary signal. “It’s unprecedented, this switch in the wastewater signal,” Tyson Graber, an associate research scientist at the Children's Hospital of Eastern Ontario Research Institute (CHEO) told media about the emergence of Omicron in Ottawa’s wastewater over December 2021. In Saskatchewan and parts of Ontario, for instance, the levels of the COVID-19 virus detected in wastewater has jumped nearly 90% since Omicron was first identified in December 2021.
