Overview
- The state announced Thursday that Tyco Fire Products, a Johnson Controls subsidiary, agreed to pay $10 million into Wisconsin’s PFAS trust as part of a settlement that must be approved by a judge.
- Under the deal Tyco must provide clean drinking water for 20 years, maintain monitoring and reporting, and pursue further soil, groundwater and surface-water cleanup at the Marinette Fire Technology Center.
- State filings and sampling show contamination discovered in 2013 with PFOA readings in groundwater as high as 254,000 parts per trillion and 236 of 776 private wells testing above state advisory levels.
- Tyco says it has spent more than $100 million on investigations, treatment and water supplies, has treated hundreds of millions of gallons of groundwater since 2022, and has installed or contracted deep wells for most affected homes.
- The Marinette case remains tied to broader PFAS litigation, having been centralized in a federal multidistrict court in South Carolina, and the settlement follows recent state moves to free $133 million from the PFAS trust for cleanup work.
