EPA plans to limit toxic forever chemicals in drinking water for the 1st time
CHICAGO — Water utilities will be required to routinely test for toxic forever chemicals, and spend billions upgrading treatment plants to filter them, under the first-ever national limits intended to protect Americans from widespread threats to human health and the environment.
In Illinois alone, the drinking water of more than 660,000 people is contaminated at levels exceeding the proposed standards for per- and polyfluoroalkyl substances or PFAS.
