Characterization of Per- and Polyfluoroalkyl Substances in Drinking Water Sources in the Greater Montreal Area, Quebec, Canada Open
Per- and polyfluoroalkyl substances (PFAS) are persistent organic pollutants that are subject to increasingly restrictive regulations. This study characterized the occurrence of 77 PFAS compounds in raw and treated water from 15 drinking w…

Full-scale characterization of the effects of a bioretention system on water quality and quantity following the replacement of a mixed stormwater and combined sewer system Open
Urbanization is leading to more frequent flooding as cities have more impervious surfaces and runoff exceeds the capacity of combined sewer systems. In heavy rainfall, contaminated excess water is discharged into the natural environment, d…

Hydrological and physicochemical parameters associated with SARS-CoV-2 and pepper mild mottle virus wastewater concentrations for a large-combined sewer system Open
During COVID-19, surveillance of SARS-CoV-2 in wastewater has been a promising tool for tracking viral infection at the community level. However, in addition to the shedding rates within the community, SARS-CoV-2 concentrations in raw wast…

Strategic prioritization of sewersheds to mitigate combined sewer overflows under climate change Open
The impact of combined sewer overflows (CSOs) on water bodies is well documented: they pose severe threats to water quality, ecosystems, and public health. Exposure to contaminants from overflows can lead to waterborne diseases, emphasizin…

Risk assessment of drinking water intake contamination from agricultural activities using a Bayesian network Open
Agricultural activities can result in the contamination of surface runoff with pathogens, pesticides, and nutrients. These pollutants can enter surface water bodies in two ways: by direct discharge into surface waters or by infiltration an…

Comparative study of deterministic and probabilistic assessments of microbial risk associated with combined sewer overflows upstream of drinking water intakes Open
RÉSUMÉ: Combined sewer overflows (CSOs) are a source of microbial contamination of drinking water intakes located downstream from their discharge. To safeguard the quality of the source water, it is essential to evaluate the risk levels as…
