PFAS

Updates From DHS Clarify Hazard Index Reporting

On June 7, the Wisconsin Department of Health Services (DHS) provided the Wisconsin Department of Natural Resources (DNR) with an updated letter on the utilization of the hazard index (HI) approach to assess the cumulative risk of PFAS (per- and polyfluoroalkyl substances).

This updated letter clarifies recommendations provided to the DNR in November 2020, making clear that the hazard index should be reported to one decimal place (examples are provided in the memo). No other changes to the DHS recommended approach were made.

DNR Adopts the Department of Health Services’ Recommended Hazard Index (HI) Approach

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.

Wisconsin Adjusts PFAS Default Reporting List for Regulatory Sampling and Lab Certification from 36 to 33 PFAS Compounds

After careful consideration, effective March 1, 2021, the Wisconsin Department of Natural Resources (DNR) no longer expects regulated entities, unless otherwise directed by DNR, to sample for or laboratories to report three of the 36 PFAS compounds on the default PFAS list. Site-specific circumstances may influence whether the DNR approves a deviation for sampling for those 33 PFAS compounds.

Reminder Letter Sent to Responsible Parties to Evaluate for Emerging Contaminants During Site Investigations

The Remediation and Redevelopment (RR) Program is sending 3,038 letters to parties responsible for cleanup at open remediation sites in Wisconsin.

The letter is a reminder to those responsible parties (RPs) to consider per- and poly-fluoroalkyl substances (PFAS) or other suspected emerging contaminants (e.g. 1,4 – Dioxane) during the site investigation scoping phase of their remediation efforts, per NR 716.07 and NR 716.09. A site investigation may be considered incomplete if the RP does not consider and address all hazardous substances or environmental pollution at a known site or facility subject to ch. 292, Wis. Stats., including emerging contaminants like PFAS.  Failure to do so could result in the need for additional assessment work or field work and potential closure delays.
