The Environmental Protection Agency is rolling back rules limiting forever chemicals in drinking water. The Trump administration plans to weaken drinking water rules meant to protect Americans from “forever chemicals” that have been linked to cancer, reproductive risks, liver damage, and other health issues.

The administration said it wants to rescind and reconsider whether limits are needed for four PFAS that chemical companies are still producing and using in the U.S. — despite known health risks.

PFOA and PFOS have been found in the drinking water of 200 million Americans, including 6 out of 10 Illinoisans.
