Per-and Polyfluoroalkyl Substances (PFAS) in United States Tapwater: Comparison of Underserved Private-Well and Public-Supply Exposures and Associated Health Implications
Science
26 Jun 2023 | Environ. Int.
Models based on drinking water testing suggest that at least one PFAS is present in 45% of US drinking water. The authors recommend that monitoring should be improved by including more rural and private wells and by expanding target and non-target analysis methods.
