The manufacturer of a firefighting foam that contaminated the water supply in northeastern Wisconsin with PFAS chemicals for decades agreed to a $10 million settlement with the state, the governor and attorney general announced on Thursday.

The settlement comes as residents, communities, regulators and environmental activists across the country are struggling with how to address contamination from PFAS, also known as “forever chemicals.”

Democratic Gov. Tony Evers hailed the settlement with Tyco Fire Products as a “historic and important milestone” in the fight for clean water. The lawsuit filed in 2022 alleged that Tyco, a subsidiary of Johnson Controls, had contaminated the area around a firefighting training center since the 1960s and did not do enough to address it.

“Today’s a key step toward making sure polluters are held accountable, take responsibility for their actions, and ensure Wisconsinites don’t have to foot the bill for cleaning up the messes that others made,” Evers said in a statement announcing the deal.

But residents of the affected city of Marinette were hoping for more.
