A bipartisan group of legislators has proposed a bill to require the state Department of Natural Resources to warn county and tribal health departments when an exceedance of state groundwater standards is discovered.

The proposed bill, which was circulated for co-sponsorship Monday by Rep. Jill Billings, D-La Crosse, Rep. Todd Novak, R-Dodgeville, and Sen. Jesse James, R-Thorp, would include warnings about the presence of PFAS — even though the state has been unable to finalize a PFAS limit for groundwater.

That provision would allow private well owners to be warned about the presence of PFAS despite the yearslong political quicksand that has mired the effort to enact a contaminant limit for the class of chemicals. The lack of a PFAS standard has been a regular sticking point in negotiations over legislation to spend $125 million already set aside for PFAS clean up.

While the state doesn’t have a PFAS groundwater standard, it does have standards for nearly 150 other chemicals such as aluminum, nitrates and lead.

About one-third of Wisconsinites get their drinking water from private wells, which don’t come with the same warnings that are often required of municipal water systems.

“The public should be able to know if there is any threat to the safety of the water they and their children drink every day,” the co-sponsorship memo states. “This bill would provide Wisconsinites with more knowledge so they can protect themselves and their children from pollutants and allow them to take advantage of local and county-level testing initiatives and state-level assistance opportunities like the Well Compensation Grant Program.”

After the legislation’s announcement, environmental groups celebrated it as a potential win for clean water.

“Wisconsinites have a right to know about pollution that may be impacting the health of their families,” said Peter Burress, government affairs manager for Wisconsin Conservation Voters. “This legislation is a common sense solution that will protect Wisconsin families. It’s unacceptable that so many Wisconsin families could be drinking water contaminated with PFAS, lead, and nitrates — chemicals tied to cancer and birth defects — without ever being told.”

Marinette and the Town of Peshtigo in Marinette County are among the Wisconsin communities dealing with PFAS contamination.
