EPA’s Exclamation that PFAS Are Unsafe in Minute Concentrations Is Turning Out To Have Serious Ramifications for Many, Including EPA
News
26 Jul 2024 | The National Law Review
The lawsuit Maine farmers joined this week is conclusive evidence of the insufficiency of that EPA guidance. Legislation exempting “passive receivers” of PFAS like water utilities from liability under Federal environmental law would be more effective but whether, and when, Congress and the President might agree on such legislation is anything but certain, even if it were a good idea.
