Wisconsin officials offer water quality standards for PFAS


Wisconsin health officials said Friday they’ve finished drafting new groundwater standards for more than 20 substances, including a dozen types of PFAS chemicals.

The Department of Natural Resources asked the Department of Health Services in April 2019 to begin researching the health impacts of 40 unregulated substances and provide recommendations on how much of each substance should be allowed in groundwater. The DNR plans to use the recommendations as the basis for writing an administrative rule establishing standards that will apply to bottled water, agricultural chemicals, clean-up at contaminated sites and landfills.

DHS officials said they reviewed scientific literature about each substance and came up with recommendations for 22 of the 40 substances, including 16 types of PFAS and six pesticides. The department said it couldn’t come up with recommendations for the remaining 18 due to limited information on their effect on human health.
