The State of Wisconsin’s legal battle against PFAS contamination is growing. Governor Tony Evers and Attorney General Josh Kaul are taking legal action against more companies for contamination from PFAS. Kaul says, “what we’ve alleged in this lawsuit is that for decades companies that were involved in manufacturing, selling, and marketing of PFAS were aware of the danger that PFAS presented to human health. That includes 3M and DuPont, among others.”

The lawsuit seeks punitive damages and reimbursement for the costs of investigations, cleanup, and remediation. The dollar amount isn’t set but Attorney General Kaul says the current cost from the issues is over $1 billion and taxpayers are stuck footing the bill. Filed in Dane County circuit court, the lawsuit names 18 companies as defendants, including 3MCompany, Tyco Fire Products LP, and BASF Corporation. The filing alleges the defendants knew or should have known that their products would have a dangerous impact on the public’s health and environment. Chemguard and Chemdesign of Marinette are also named as defendants.


A spokesperson from Tyco says, “Tyco took responsibility for its part in the PFAS contamination in Wisconsin many years ago and has spent millions of dollars on a comprehensive clean-up program that is well ahead of any other effort in the state and likely the country. The state is well aware that PFAS contamination is widespread in Wisconsin from multiple sources but has done little to deal with those other sources, include them in today’s lawsuit, or ensure clean water for its people. Unfortunately, today’s lawsuit appears to be about politics and a fast-approaching election more than it is about public health or the environment. Today’s lawsuit will not stop Tyco from doing the right thing and leading on the PFAS cleanup, and we will continue remediation efforts underway even while we defend this lawsuit in due course.”


The state filed a lawsuit against Tyco Fire Products and Johnson Controls earlier this year. Kaul says that lawsuit focused on spills in the Marinette and Peshtigo areas and failing to address the PFAS contamination.
