June 2023 Articles
Environmental Science & Engineering Magazine’s June 2023 issue. Article topics include: reducing non-revenue water, finding and fixing inflow and infiltration, odour control biofilter rehabilitation, responding to the Iqaluit drinking water crisis, wastewater surveillance and much more. Plus, our Annual Guide to Environmental Academic Institutions and Training Providers.
Asset management and diversity, equity and inclusion go hand in hand
ES&E Magazine sat down with Toronto Water and CIMA+ to discuss how asset management is benefiting from, and supporting, Canada's water sector.
How site remediation can improve long-term economic success in NWT
There is a pathway forward for the Northwest Territories to invest in environmental remediation, and reap the rewards of such an investment.
Reducing your carbon footprint with heat exchangers
Heat exchangers can reduce the energy consumption (and therefore greenhouse gas emissions) of thermal processes in a wide range of industries.
Understanding the basic principles of water treatment media pilot trial design and evaluation
Properly designing, operating, and analyzing data from a water treatment media pilot trial will yield valuable performance data.
Research projects blaze trails at Canadian colleges and universities
Canadian colleges and universities made headlines this spring with an array of innovative and meaningful research projects.
Biological ion exchange shows promise to deliver safe water
With conventional methods being prohibitively expensive for the small community, a pilot study successfully examined biological ion exchange for water.
The benefits of using connected safety devices in water, wastewater facilities
Connected technologies can keep water industry workers safe, while also improving productivity, highlighting trends and lowering the likelihood of future incidents.
Biofilter rehabilitation at Toronto’s Humber Wastewater Treatment Plant
During replacement of the biofilter media and tank clean-out, it was decided to improve the tanks' containment integrity with a geomembrane lining system.
Responding to the Iqaluit water crisis
In October 2021, residents complained of a fuel-like smell coming from tap water. Then, fuel-like contamination was discovered at the water treatment plant.
Town of Smiths Falls reducing non‑revenue water losses
A series of water audits found the Town's non-revenue water was above 60%. Consequently, it began searching for a solution that could reduce this figure.
Balancing environmental responsibility while expanding wastewater management infrastructure
Pressure sewers offer an alternative sanitary sewer option because they provide an economic solution to challenging environmental conditions, where gravity sewers are impractical and where septic systems pose risks to the environment.
Monitoring runoff helps protect health of Great Barrier Reef
Sediment, nutrient and pesticide run-off from catchments is contributing to the pressures on marine ecosystems along the Queensland, Australia coast, including the Great Barrier Reef and Moreton Bay. Quantifying the amounts of these constituents in runoff (in both concentration and tonnage) is critical to the effective management of these risks.
Closer to source means faster, clearer results from wastewater surveillance
Standing in traffic to get a wastewater RNA sample through a sewer maintenance hole may not be ideal, but it may be more effective. While logistically, there is a simplicity to obtaining and monitoring samples directly at the wastewater treatment plant, easier does not always mean better.
Small town of Lumsden leads Saskatchewan with solar-powered WWTP
The scenic Town of Lumsden has achieved an innovative feat by becoming the most solar-driven municipality in Saskatchewan, thanks to its award-winning venture of powering a brand-new wastewater treatment plant with the endless energy of the sun.
Finding and fixing sewer inflow and infiltration problems
An important concept to understand about addressing I/I is that it is not just an engineering issue. To implement a long-term I/I program, the entire municipality needs to be involved. The work must be supported by the CAO and engineering, development, building, by-law, and planning departments need to participate.
ES&E Magazine celebrates 35 years of publishing
The year 2023 is indeed a milestone year. It marks Environmental Science & Engineering Magazine’s 35th birthday and 130 years of environmental journalism in Canada. It also marks the 40th anniversary of a research project I did to commemorate Water & Pollution Control Magazine’s (W&PC) 90th birthday in 1983.
Toronto’s new storm trunk sewer will reduce basement flooding during severe storms
In what is Toronto’s most ambitious basement flooding prevention project to date, city workers have started work on a large storm trunk sewer that will be part of a system to collect, store and...
CSA Group report calls for wider use of nature-based solutions for flooding, erosion
The CSA Group has released a new report designed to help governments shift from traditional grey or engineered infrastructure, such as walls and dikes, to nature-based solutions like restoring forests and wetlands, to manage...
Canada establishes guidelines for boron in drinking water

Health Canada says impact of air pollution costs more than $100B annually
A new report from Health Canada details the health and financial consequences of exposure to ambient air pollution across Canada.
After analyzing outdoor air pollution data spanning 2014 to 2017, the report's findings suggest that...
Whitehorse weighing move to multi-barrier drinking water treatment
The City of Whitehorse’s water experts say additional treatment processes and disinfection are necessary for their drinking water as its quality has slowly degraded due to the influence of surface water over time.
But the...
EPA asks water utilities to include cybersecurity practices for audits
Cybersecurity protocols must be integrated into audits for U.S. water utilities, says the Environmental Protection Agency (EPA), as it works to clarify definitions and required actions to close cybersecurity gaps that leave infrastructure vulnerable.
The...
