Oct 24, 2024 · People in the United States may unknowingly be drinking water that contains PFAS because of a lack of systematic analysis, particularly in domestic water supplies. We present an extreme gradient–boosting model for predicting the occurrence of PFAS in groundwater at the depths of drinking water supply for the conterminous United States. Our ...

Jul 5, 2023 · At least 45% of the nation’s tap water is estimated to have one or more types of the chemicals known as per- and polyfluorinated alkyl substances, or PFAS, according to a new study by the U.S. Geological Survey.

This fact sheet answers questions about per- and poly-fluoroalkyl substances (PFAS) in drinking water in your home (i.e., tap water). It also includes information about potential health effects associated with PFAS exposure, and ways to limit your …

Apr 8, 2024 · A new study of more than 45,000 water samples around the world found that about 31 percent of groundwater samples tested that weren’t near any obvious source of contamination had PFAS levels...
