PFAS

Perfluoroalkyl and polyfluoroalkyl substances

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are a large group of human-made chemicals that have been used in industry and consumer products worldwide since the 1950s.

On April 6, 2026, Gov. Evers signed Act 201, which creates several new grant programs to help Wisconsin's communities address PFAS contamination, especially in drinking water, and Act 200, which provides the funding for these new grant programs.

Some of the new funding opportunities include sampling drinking water at schools and daycares that use their own well and sampling high-capacity irrigation wells, biosolids, sludge, wastewater and landfill leachate for PFAS. Together, these bills are a critical step toward ensuring that Wisconsinites have access to safer water and to reduce exposure to PFAS through the environment.

Because the law creates new grant programs, it will take time for the DNR to set up and hire staff to administer them. The DNR is committed to moving quickly to ensure these programs and assistance are available to those who need it most.

The DNR welcomes your input on the development of these programs.

Act 201 also includes narrow exemptions to the state's environmental contamination cleanup law, known as the Spills Law, for certain releases of PFAS to the environment. The Act will also result in the DNR issuing a new general permit that includes conditions for monitoring PFAS in wastewater.
