HGS HIGHLIGHT – Estimating cumulative wastewater treatment plant discharge influences on acesulfame and Escherichia coli in a highly impacted watershed with a fully-integrated modelling approach
In this research highlight, researchers used HydroGeoSphere (HGS) to explore the impact of wastewater treatment plant (WWTP) discharge on surface water contamination in a mixed-use watershed in Ontario, Canada. The study focused on tracking acesulfame, a commonly used artificial sweetener, and Escherichia coli (E. coli), a fecal indicator, to understand how these contaminants move between surface and groundwater systems. Understanding the interactions between surface water and groundwater is critical in watersheds where WWTP discharge contributes to regional water quality concerns.
