WMC submitted comments to the state DNR in opposition to new water system guidance related to PFAS. The new guidance imposes reporting requirements when a drinking water system detects PFAS at levels that exceed the state’s so-called “PFAS Hazard Index,” which includes recommended levels for 18 PFAS. The guidance requires ongoing public notice (every 3 months), including the PFAS testing results and a recommendation for addressing the exceedance (such as replacing the well or treatment).
In comments, WMC noted the PFAS Hazard Index includes only recommendations, not requirements, and only two PFAS – PFOA and PFOS – have lawfully promulgated standards. WMC urged DNR to withdraw the guidance and instead utilize the transparent rulemaking process, to allow the public and the business community to weigh-in on the proposed standards.
