The Wisconsin PFAS Action Council published its 2022 PFAS Action Plan Progress Report in August. The progress report presented progress in the eight themes that are covered in the states PFAS Action Plan to address statewide PFAS contamination.

The U.S. Environmental Protection Agency (EPA) released updated health advisories in June for PFAS compounds in drinking water. These new limits significantly reduce the guidelines previously established in 2016. The new drinking water interim health advisories reduce the limit for both PFOA (perfluoro-octanoic acid) and PFOS (perfluoro-octane sulfonate).
