Per and Polyfluoroalkyl Substances (PFAS) in New Jersey surface waters

Scientists from the New Jersey Water Science Center are working with drinking water purveyors to assess the occurrence and distribution of per- and polyfluoroalkyl substances (PFAS) in New Jersey surface waters. These studies will enhance current water-quality assessments in NJ watersheds by characterizing PFAS occurrence in surface water at select locations that have the potential to directly...
