Isolating the AFFF Signature in Coastal Watersheds Using Oxidizable PFAS Precursors and Unexplained Organofluorine Open
Water supplies for millions of U.S. individuals exceed maximum contaminant levels for per- and polyfluoroalkyl substances (PFAS). Contemporary and legacy use of aqueous film forming foams (AFFF) is a major contamination source. However, di…
View article: Surface-water/groundwater boundaries affect seasonal PFAS concentrations and PFAA precursor transformations
Surface-water/groundwater boundaries affect seasonal PFAS concentrations and PFAA precursor transformations Open
Aqueous PFAS concentrations fluctuate seasonally and precursor concentrations rapidly decline within the surface-water/groundwater boundary, indicating that transport through this boundary can affect spatial and temporal PFAS composition.
