PFAS chemicals have forever topped the new EPA limits. Is your location on our map? – Top Stories (Trending Perfect)


Millions of Americans rely on drinking water systems that recently exceeded new limits for toxic chemicals announced by the Environmental Protection Agency on Wednesday.

USA TODAY found 608 systems across the country that have measured PFAS, or polyfluoroalkyl substances, at or above newly established limits since last year. Together they serve nearly 35 million people.

Another 13 million people drink water from hundreds of other systems that recently detected chemicals at levels that would require reporting to the EPA, but not enough to exceed the new limits, according to a USA TODAY analysis.

These results represent one-time sampling, and the EPA will not require water systems to make changes unless their running annual average exceeds the new limits.
