Green Bay Appleton, WI, October 28, 2026 —
Wisconsin’s Natural Resources Board has unanimously approved groundwater standards for six PFAS substances, advancing a rule that still needs approval from the governor and Legislature before it can take effect.
The standards are intended to protect public health from PFAS, often called “forever chemicals.” The board’s vote follows previous attempts to establish the standards that failed. The summary provided does not specify when those attempts occurred or describe the reasons they did not succeed.
Industry and wastewater groups have raised concerns about the costs of complying with the proposed requirements. The available information does not identify the groups, provide estimates of potential costs, or describe the specific compliance measures the rule would require.
The approval by the Natural Resources Board is not the final step in the process. The rule still requires approval from both the governor and the Legislature. No timeline for those decisions was provided, and the available information does not say whether either has acted on the rule.
The standards cover six PFAS substances, but the specific substances and the groundwater limits were not provided. Details about implementation, enforcement, and any effect on particular communities or water systems were also not included. Until the remaining approvals are addressed, the rule’s status remains subject to those steps.
