DNR Adopts the Department of Health Services’ Recommended Hazard Index (HI) Approach for Evaluating Human Health Risk of Certain PFAS due to Ingestion of Drinking Water

On Nov. 6, 2020, the Wisconsin Department of Health Services (DHS) provided the Wisconsin Department of Natural Resources (DNR) recommended groundwater standards for 16 PFAS substances (known as “Cycle 11”). Shortly thereafter, DHS provided recommendations to DNR for utilizing a hazard index approach to assess the cumulative risk of these PFAS, including PFOA and PFOS from Cycle 10. The hazard index risk assessment approach is used to assess the cumulative risks of compounds with similar health effects that are typically found as mixtures in environmental samples. This approach has been employed by DHS to evaluate certain classes of pesticides and volatile organic compounds as well as by the United States Environmental Protection Agency (EPA) to evaluate the risk posed by non-carcinogenic chemicals found at Superfund sites.
