PFAS Law Implementation

Acts 200 and 201 together create and fund new grant programs to help Wisconsin's communities address PFAS contamination, especially in drinking water. Some of the newly created 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. These Acts also expand the Well Compensation Grant Program with higher income limits and additional funding so more households and businesses with contaminated private wells are eligible for funding assistance.

Because the law creates new grant programs, it will take time for the DNR to set up and hire staff to administer them.

Opportunities for Public Involvement

Submit questions and feedback. Staff may not respond to all feedback but will review and consider the input as programs are developed.

Implementation Timeline

Initially, the DNR will prioritize grants for sampling of private wells, schools, childcare facilities and biosolids, which are expected to be available starting in the summer or fall of 2026.
The DNR expects the expanded Well Compensation Grant Program to be launched in fall or winter of 2026.

Implementation Goals

The DNR remains committed to a public health-centered approach to addressing PFAS. The DNR will implement programs to support sampling for PFAS and appropriate actions to disrupt exposure when PFAS are found. Potential actions to disrupt exposure could include:

Emergency/immediate actions, such as providing alternative water if a private well has PFAS levels higher than health recommendations or turning off a municipal well with higher levels of PFAS.
Interim actions, such as installing a temporary water treatment system.
Long-term actions, such as digging a new well or installing infrastructure to treat contamination.
