U.S. Environmental Protection Agency announces first-ever national regulations for “forever chemicals” in drinking water

/

Commonly called “forever chemicals,” PFAS are synthetic chemicals found nearly everywhere — in air, water, and soil — and can take thousands of years to break down in the environment.

The EPA has stated there is no safe level of exposure to PFAS without risk of health impacts, but now it will require that public water utilities test for six different types of PFAS chemicals to reduce exposure in drinking water. The new standards will reduce PFAS exposure for 100 million people, according to the EPA, and prevent thousands of deaths and illnesses.
