📢Wisconsin DNR Issues New PFAS Monitoring Requirements for Biosolids📢

The Wisconsin Department of Natural Resources (DNR) has issued a new statewide permit requiring wastewater treatment facilities that generate biosolids (sewage sludge) to monitor and report PFAS levels.

The new requirements, created under 2025 Wisconsin Act 201, are designed to help identify and reduce PFAS contamination before biosolids are land applied. The DNR has also updated its interim strategy for managing biosolids and industrial sludges containing PFAS to better protect public health and the environment.

Looking ahead, the DNR plans to launch new grant programs later in 2026 to support PFAS sampling at wastewater treatment facilities, as well as testing for private wells, schools, and childcare facilities.

PFAS, often called "forever chemicals," are found in products like non-stick cookware, food packaging, stain-resistant materials, and firefighting foam. Because they don't break down easily, they can accumulate in the environment and the human body, where they have been linked to serious health concerns.
