Geochemical and Geospatial Data for Per- and Polyfluoroalkyl Substances (PFAS) in Groundwater Used As a Source of Drinking Water in the Eastern United States Geochemical and Geospatial Data for Per- and Polyfluoroalkyl Substances (PFAS) in Groundwater Used As a Source of Drinking Water in the Eastern United States

Concentrations of inorganic constituents, dissolved organic carbon (DOC), tritium, per- and polyfluoroalkyl substances (PFAS), volatile organic compounds (VOCs), and pharmaceuticals were measured in groundwater samples collected from 254 wells in 2019 and 2020. Concentrations of inorganic constituents, DOC, VOCs, and pharmaceuticals were measured at the U.S. Geological Survey (USGS)...

Poly- and perfluoalkyl substances in contaminated groundwater, Cape Cod, Massachusetts, 2014-2016 Poly- and perfluoalkyl substances in contaminated groundwater, Cape Cod, Massachusetts, 2014-2016

Drinking water health advisories for perfluorooctanoate (PFOA) and perfluorooctane sulfonate (PFOS), were issued by the U.S. Environmental Protection Agency in 2016 in response to growing evidence associated with negative human health effects. PFOA and PFOS are often associated with other poly- and perfluorinated alkyl substances (PFAS). There has been increasing concern for groundwater...
