EPA imposes stricter limits on four types of toxic ‘forever chemicals’

EPA administrator Michael Regan announces aggressive action' but new PFAS limits are advisory and critics call them baby steps'

The US Environmental Protection Agency on Wednesday announced new advisory limits for four kinds of PFAS forever chemicals", warning that the compounds, which most Americans are exposed to daily, are far more toxic than previously thought.

The dangerous chemicals are estimated to be contaminating drinking water for more than 200 million people, and the new limits could have significant financial consequences for PFAS polluters, including the US military and producers like 3M, DuPont and Chemours.
