Per- and polyfluoroalkyl substances, better known as PFAS, are a growing area of concern for waterways in Madison and across the nation. These chemicals, which are used to make everyday products like nonstick pans and water resistant materials, have been found in drinking water and are linked to serious health effects. In this episode of the SustainUW Podcast, host Britta Wellenstein talks to PFAS researcher Onur Apul about the impact of PFAS on the environment and what technologies might allow us to remove it from our drinking water. Dr. Apul, who is an assistant professor of civil and environmental engineering at the University of Maine, presented his research at UW–Madison’s Weston Roundtable this fall.
