NR 140 Groundwater Quality Standards Update

The following is from DNR Secretary-designee Preston Cole:

I wanted you to know that DNR is pleased to report that we continue to make progress on advancing the Governor’s “Year of Clean Drinking Water” initiatives and returning Wisconsin to being a leader in the field of environmental protection.  This morning, the Wisconsin Department of Health Services (DHS) provided DNR and the Department of Agriculture, Trade and Consumer Protection (DATCP) with recommended standards for 27 groundwater contaminants (ch. NR 140 compounds). These recommendations are intended to protect human health and the environment, as part of Wisconsin’s landmark groundwater law, Chapter 160, Wisconsin Statutes. Included in this package are recommended standards for glysophate, perfluorooctanoic acid (PFOA), and perfluorooctanesulfonic acid (PFOS).

Comprehensive Per- and poly-fluoroaklyl (PFAS) Legislation Proposed

Today, Governor Evers and Secretary Cole accompanied Senators David Hansen (Green Bay) and Mark Miller (Monona) to announce one of the most comprehensive bills in the nation to address contamination by per- and poly-fluoroalkyl substances (PFAS). This bill (LRB-2297/2), if passed, will protect public health as well as the air, waters and lands of Wisconsin.

What would the legislation do?

  • This bill requires the Department of Natural Resources to establish and enforce various standards for per- and poly-fluoroalkyl substances (PFAS).
  • The PFAS group of substances includes several thousand chemicals (4,000+); two of the most well-known are perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS).
  • The bill requires DNR to establish, by rule, the following:
    • acceptable levels and standards,
    • monitoring requirements, and
    • required response actions for any PFAS.
  • Applies to all media:
    • in drinking water, groundwater, surface water, air, solid waste, beds of navigable waters, and soil and sediment, if the department determines that the substance may be harmful to human health or the environment.
  • These rules must cover, at a minimum, PFOA and PFOS, as well as perfluorohexane sulfonic acid (PFHxS), perfluorononanoic acid (PFNA), perfluorobutane sulfonic acid (PFBS), and perfluoroheptanoic acid (PFHpA).
  • In recommending a groundwater enforcement standard for a perfluoroalkyl or polyfluoroalkyl substance, the department of health services may recommend individual standards for each substance, a standard for these substances as a class, or standards for groups of these substances.

RR Program’s PFAS Technical Advisory Group Meetings Scheduled

The DNR’s Remediation and Redevelopment (RR) Program will convene a PFAS Technical Advisory Group (TAG) to discuss PFAS-related concerns that are specific to the assessment and cleanup of environmental contamination.

The goal of the group is to examine the “what, where, when and how” of PFAS investigation and remediation by sharing concerns, identifying current and proposed practices, and strategizing on issues requiring solutions. The group does not have an appointed membership; any interested party may attend.
