3M reports over 20k US products with PFAS in 2021-2022; Wisconsin court restricts PFAS cleanup without specific limits.

Maine lists thousands of products containing 'forever chemicals' such as BIC razors & floor finishes; 3M Co. reported over 20k products with PFAS in the US in 2021-2022. A Wisconsin appeals court ruled that environmental regulators cannot mandate polluters to clean up PFAS contamination without establishing specific limits on the compounds, which could slow the DNR's response to other pollution issues.
