Water systems have until 2029 to comply with new, stringent levels of PFAS allowed in drinking water. The EPA has added 196 PFAS to the Toxics Release Inventory, or TRI, in response to a congressional mandate.
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.
Drinking-water exposures to per- and poly-fluoroalkyl substances (PFAS) are a national concern, however, there is limited information on PFAS in residential tapwater at the point-of-use, especially from private-wells.
Data on contaminated water system, industrial and military sites was current as of August 2024. There are 2,067 sites that reported PFAS via UCMR 5, as of August 2024. The Environmental Working Group welcomes requests to reproduce EWG PFAS data for peer-reviewed articles in scientific journals.
People can be exposed to PFAS through drinking water or food contaminated with PFAS, by coming into contact with products that contain PFAS, or through workplace exposures in certain industries.
EPA encourages states, Tribes, territories, drinking water utilities, and community leaders that find PFAS in their drinking water to take steps to inform residents, undertake additional monitoring to assess the level, scope, and source of contamination, and examine steps to reduce exposure.
EPA expects that over many years the final rule will prevent PFAS exposure in drinking water for approximately 100 million people, prevent thousands of deaths, and reduce tens of thousands of serious PFAS-attributable illnesses.
The maximum concentration of PFOA was observed in both drinking water sources (11,000 ng/L) and supplies (4300 ng/L) in the United States, while the highest level of PFOS was detected in...
As the first-ever Safe Drinking Water Act standard for PFAS – and the first for any new contaminants since 1996 – this rule sets health safeguards and will require public water systems to...
Almost 800 drinking water systems across the United States have recently measured PFAS at or above the newly established limits at least once, according to a USA TODAY analysis of data the EPA...
