Abstract: Drinking-water quality is an evolving concern in the United States, emphasizing the need to broadly assess exposures and potential health effects at the point-of-consumption. Drinking-water exposures to per- and poly-fluoroalkyl substances (PFAS) are a national concern, however, there is limited information on PFAS in residential tapwater, especially from private-wells. We conducted a national reconnaissance to compare human PFAS exposures in regulated public-supply and unregulated private-well tapwater. Concentrations of 32 target PFAS were assessed as fractional indicators of the presumptive 8000+ PFAS contaminant-space and compared with land-use and potential-source metrics to explore drivers of contamination. The presentation will provide a brief overview of U.S. Geological Survey, Environmental Health Program PFAS research with an emphasis on our national reconnaissance designed to assess human exposures and potential effects of PFAS nationally in tapwater collected at the point-of-use.
