Per- and Polyfluoroalkyl Substances (PFAS)
Per- and polyfluoroalkyl substances (PFAS), also commonly referred to as perfluorinated chemicals or PFCs, are a group of anthropogenic chemicals with past and current uses in industrial processes and consumer products—firefighting foams, coating for food packaging, ScotchGard™, and Teflon™, among other products. These compounds are inert, heping surfaces resist stains, grease, and water.
These same properties mean PFAS does not break down easily, and therefore persist in the environment. Evidence indicates that exposure to these compounds can lead to adverse human effects. They are also soluble in water and can enter source waters through industrial releases, discharges from wastewater treatment plants, stormwater runoff, release of firefighting foams, and land application of contaminated biosolids. This group is looking to better understand the science behind PFAS dicsussing monitoring and treatment in both drinking water and wastewater settings.
