PFAS, a large class of human-made chemicals, continues to present a major public health concern in Wisconsin and beyond. Since the Center published its PFAS policy brief in 2023, the U.S. Environmental Protection Agency (“EPA”) issued an April 2024 final rule establishing drinking water standards—also referred to as MCLs—for six PFAS compounds. EPA signaled in May 2025 an intent to rescind standards for four of those compounds, but no formal rulemaking has begun.
Our updated Policy Brief breaks down the legal context, timelines, and key implications—and offers recommendations for navigating what comes next.
