PFAS (per- and polyfluoroalkyl substances) are manufactured chemicals that are found in many everyday products, including nonstick pans, cleaning products, paints, and firefighting foam. PFAS are present in the bloodstream of 98 percent of Americans. Competing studies debate whether or not PFAS have negative health effects, and, if they do, at what level they are harmful. The federal Environmental Protection Agency has declined to regulate PFAS in drinking water. Meanwhile, some states are choosing to implement regulations independently. Hamilton Consulting closely monitors regulatory developments related to PFAS both at the state and federal level. Click on the links below for more information on PFAS regulations.
Regulatory: DHS has announced a recommended groundwater standard of 20 ppt combined for PFOA and PFOS. The recommendation now must go through the DNR rulemaking process before it is enforceable. DHS also recommends that the NR140 Groundwater Quality Public Health Preventive Action Limit for PFOA and PFOS be set at 10% of the enforcement standard “because PFOA and PFOS have been shown to have carcinogenic, teratogenic, and interactive effects.” At just 2 ppt, the Preventive Action Limit would be the strictest PFAS standard in the world.
The DNR board has approved a preliminary public hearing and comment period on three scope statements proposing to regulate PFAS chemicals. Read all comments here.
After the comment period, the DNR Board can approve the scope statements. DNR plans to ask the board for approval in January 2020. Once the board approves the scope statements, DNR can begin work on drafting the rules and economic impact analyses.
Scope statements are the first step in the rulemaking process, which DNR estimates takes about 30 months. The scope statements would:
DNR has already asked municipal wastewater treatment plants to test water flowing in and out of facilities for PFAS.
DNR is also convening a PFAS technical advisory group, meeting on a quarterly basis starting in February 2019.
Legislation: Several bills addressing PFAS are circulating in the Wisconsin Legislature.
SB 310/AB 323 Rep. John Nygren (R-Marinette) & Sen. Rob Cowles (R-Green Bay)
The bill would prohibit the use of fire fighting foams that contain intentionally added PFAS in training, unless the testing facility has appropriate containment and treatment measures (as determined by Department of Natural Resources (DNR) rule).
SB 302/AB 321 Sen. Mark Miller (D-Monona), Sen. Dave Hansen (D-Green Bay), Rep. Chris Taylor (D-Madison), Rep. Stausch Gruszynski (D-Green Bay) & Rep. Melissa Sargent (D-Madison)
The bill would require DNR to establish and enforce PFAS standards by rule for drinking water, groundwater, surface water, air, solid waste, beds of navigable waters, and soil and sediment if DNR deems it harmful to human health or the environment. The bill also provides that DNR may require entities possessing PFAS to provide proof of financial responsibility for remediation of potential discharge. Additionally, the bill requires any facility under investigation by DNR to provide DNR with access to information related to transportation of hazardous waste to any other site. The bill provides 7.5 positions at DNR and 2 positions at DHS, plus $150,000 for identifying and prioritizing PFAS sources, $50,000 for a study on use of fire fighting foam containing PFAS, $87,000 for testing landfills and leachate, and $120,000 for investigation of PFAS sources and providing drinking water.
The Wisconsin Legislative Council has released a high-level issue brief on PFAS.
Wisconsin Democrats have included preventing PFAS contamination in their Forward Together agenda.
Budget: The state budget included two positions for PFAS and other emerging contaminants research at DNR. The budget also included $150,000 GPR to develop a model to identify and prioritize sites with likely PFAS contamination and $50,000 to conduct a survey on emergency response use of PFAS-containing firefighting foam.

The federal Environmental Protection Agency (EPA) has released draft preliminary guidelines for PFOA and PFOS. The interim recommendations follow EPA’s PFAS Action Plan announced earlier this year. EPA is currently seeking comments on an advance notice of proposed rulemaking to add PFAS to the Toxics Release Inventory.
In Congress, the issue of PFAS is working its way through committees in various capacities.
On July 30, Wisconsin Attorney General Josh Kaul joined 21 other state attorneys general in urging Congress to regulate PFAS. On Sept. 18, Wisconsin Gov. Tony Evers joined 14 other governors in asking congressional armed services committees to include several PFAS provisions in the National Defense Authorization Act.
