Drinking-water quality and potential exposures to per- and poly-fluoroalkyl substances (PFAS) at the point-of-use (tapwater) are a rising concern in the United States (US). To understand potential exposures to PFAS at the point-of-use, 716 locations (269 private-well; 447 public supply) were sampled across the US between 2016 and 2021. Results from this national reconnaissance, including data on potential PFAS sources, are compiled and displayed in this interactive dashboard.
