Are PFAS regulated by the federal or state government?

Currently, there is limited regulatory authority of PFAS at the federal level. In 2016, the EPA issued a non-enforceable Lifetime Health Advisory level for PFOA and PFOS of 70 parts per trillion (ppt) in drinking water. EPA is expected to update its advisory in late 2022.

The Wisconsin Department of Natural Resources (DNR) has proposed drinking water and groundwater standards for 18 PFAS compounds. These standards are based on recommendations that DHS established in 2019 and 2020. To learn more about how groundwater standards are developed, visit the DHS groundwater standards website at and search “groundwater standards”.
