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).

RR Program Web and IT Updates

The Remediation and Redevelopment (RR) Program has created a new web page for contaminated soil and sediment, and recently completed additional webpage updates.

The new contaminated soil and sediment web page contains guidance and instructions on the soil RCL calculator and information about alternative soil assessments, soil and materials management under Wis. Admin. Code ch. NR 718, historic fill exemptions, contaminated sediments, PCBs in soil, smear zone contamination, and biodegradation as a remedial action.

If you already have Resources for Environmental Professionals bookmarked, a link to the new webpage can be found in the “Related Links” section, as well as at the top of that page for a limited time.

A meeting agenda and presentation materials will soon be posted on the PFAS Technical Advisory Group web page.

DNR and DHS Work Together to Improve Water Quality in Wisconsin

The Department of Natural Resources announced two new water quality initiatives as part of Governor Evers’ Year of Clean Drinking Water declaration for 2019.

This week the DNR worked with Department of Health Services (DHS) to ask the health agency to review 40 contaminants for possible groundwater quality standards. This work comes on the heels of the department asking DHS last spring to review an initial 27 contaminants, including two per- and polyfluoroalkyl substances (PFAS). PFAS are a group of human-made chemicals that have been used for decades in numerous products, such as non-stick cookware, fast food wrappers, stain resistant sprays and firefighting foam.
