"Some policy experts say Wisconsin’s drinking water standards for PFAS could be vulnerable to a legal challenge after the Environmental Protection Agency announced plans to roll back limits for some chemicals.

On Monday, the EPA proposed rules that would maintain limits for the two most widely studied PFAS chemicals but drop standards for four others. EPA Administrator Lee Zeldin said the Biden administration “cut corners and failed to follow the law” when it set the first-ever drinking water standards for PFAS.

Gov. Tony Evers criticized the move.

“These actions by the Trump administration are reckless and a huge step backward in our efforts to keep folks healthy and safe,” Evers posted on X."
