Investigating PFAS And Pharmaceuticals In The Hyporheic Zone Using Multilevel Drive-Point Piezometers

With climate change, growing populations, and increasing urbanization, municipal wastewater effluent is having a greater impact on our surface water systems. When treated wastewater is discharged into streams, it carries along complex mixtures of contaminants of global concern—including pharmaceuticals, personal care products, and per- and polyfluoroalkyl substances (PFAS). To understand how these contaminants migrate and… Continue Reading »

Planting 51 Trees Speeds Up Toluene Cleanup Efforts

High-Res Groundwater Monitoring Tracks its Success: Over 40 years ago, a former industrial site in the City of Guelph, Ontario, was contaminated by toluene; the chemical plume has since leached into the underlying fractured bedrock aquifer.
