PFAS Chemicals Forever Exceeded New EPA Limits in Hundreds of Systems

Millions of Americans rely on drinking water systems that have recently exceeded new limits for toxic “permanent chemicals” the EPA announced Wednesday.

USA TODAY found 608 systems nationwide that have measured PFAS, or perfluoroalkyl 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 have recently detected chemicals at levels that require reporting to the EPA, but not enough to exceed the new limits, according to USA TODAY’s analysis.

These results represent unique samples, and the EPA would not require water systems to make changes unless their annual average exceeds the new limits.
