August 2023 Articles
Environmental Science & Engineering Magazine’s August 2023 issue includes our Annual Guide to Environmental Government Offices and Associations. Articles cover a wide range of water, wastewater and environmental protection subjects. Topics include: Reducing inflow and infiltration to increase wastewater system capacity; Manitoba takes centre stage for water; pollution liability insurance; urban stormwater solutions; artificial intelligence for air quality monitoring, membrane aerated biofilm reactor modules installed, and more.
Harnessing the power of wastewater treatment plant digesters with co‑digestion
Concerns can arise when implementing a co-digestion system that operates using both wastewater and municipal food waste. However, with the proper tools and the right collaborative partnership, WWTP operators can take the guesswork out of feeding and understanding the state of the biological system.
Manitoba takes centre stage for water
Manitoba has been making headlines with a series of water-related initiatives, including the modernization of its water strategy, access to water network data, and the establishment of new invasive species inspection stations.
Overcoming anaerobic digester failures: Shared lessons from municipal and industrial facilities
Municipal and industrial anaerobic digesters can be prone to process upsets and failures, which present significant issues for owners and operators.
Addressing the issues of legacy gas wells in Ontario
The 2021 gas explosion in Wheatley, Ontario, brought to light the thousands of abandoned gas wells drilled across the region, which have been in poor condition for decades.
Monitoring geologic carbon sequestration sites is needed to protect groundwater quality
Distributed Strain Sensing Rayleigh Frequency Shift (DSS-RFS) is the latest generation of fibre optic sensing systems employed to monitor deep well conditions
Creating wastewater system capacity to support housing: Private-side inflow and infiltration reduction success
There are many benefits of reducing significant inflow and infiltration (I&I), including obvious advantages over adding more conveyance and treatment capacity.
MABR modules installed as part of Elmira WWTP upgrade
Several membrane aerated biofilm reactor (MABR) modules were installed at the Elmira Wastewater Treatment Plant, to increase biological treatment capacity.
What are the pros and cons of arch chamber and modular tank systems?
Despite their differences, both arch chamber systems and modular tank systems play vital roles in effective stormwater management.
The use of artificial intelligence in air quality monitoring
The need for artificial intelligence is being driven by the need to cost-effectively gather large amounts of air quality data for a variety of purposes.
Dosing hypochlorite in a new wastewater treatment plant
Recently, one new wastewater treatment plant required a pump capable of accurately dosing 15% sodium hypochlorite, which is a challenging product to pump.
Exploring the vital role of pollution liability insurance for businesses and wastewater treatment plants
Unlike most liability exposures that impact a lot of businesses, pollution losses are not a frequency risk, but rather a severity risk.
Looking forward to WEFTEC 2023 in Chicago!
Attending the Water Environment Federation’s annual WEFTEC event has been an important part of my career and professional development. This began in 1987, when we formally announced the launch of Environmental Science & Engineering Magazine. As I first found out in 1987, these events truly reveal the scale and importance of the wastewater sector, especially to young professionals.

Nutrients and not temperature impact blue-green algae blooms
Using data from 464 lakes in North and South America, scientists have determined that temperature by itself does not influence the biomass of blue-green algae blooms, and that phosphorus concentration is the more defining...
Quebec’s new biochar plant set to be largest in North America
Canada’s first and largest industrial-scale biochar plant — an $80-million project capable of eventually sequestering 75,000 tonnes of carbon per year — is set to be built in Port-Cartier, Quebec, in 2024.
The decarbonization initiative...
