Wisconsin Supreme Court delivers win for environmentalists in fight over ‘forever chemicals’
June 24, 2025
The Wisconsin Supreme Court has delivered a victory for environmentalists in the battle over the regulation of “forever chemicals” known as PFAS. The court ruled Tuesday that state regulators can force landowners to clean up emerging pollutants such as PFAS before they are officially designated as hazardous substances. The ruling from the liberal-controlled court is a defeat for the state’s powerful group representing businesses and manufacturers, which had argued the state couldn’t enforce regulations on substances before they were officially designated as hazardous. It is the latest development in a yearslong battle involving regulators, environmentalists, politicians and businesses over how to deal with PFAS contamination.
