Grant & Eisenhofer achieved a $110 million partial settlement in PFAS contamination litigation
Plaintiff(s):
State of Ohio ex rel. Dave Yost, Attorney General
Case type / claims:
G&E represents the Attorney General for the State of Ohio in litigation against a variety of chemical companies that manufactured and distributed aqueous film-forming foam (AFFF) containing per- and polyfluoroalkyl substances (PFAS), including toxic PFAS chemicals known as PFOA and PFOS. The primary manufacturers of PFAS-laced AFFF products include the 3M Company, Tyco Fire Products, Chemguard, Inc., Buckeye Fire Equipment, Kidde-Fenwal, Inc., and National Foam, Inc. Ohio asserts that these and other manufacturers, including PFAS manufacturers such as DuPont and Chemours, developed early knowledge of the toxicity and environmental hazards associated with the routine use of their products, which—when used in firefighting exercises—inevitably contaminate groundwater, seeping into public drinking water supplies and private wells.
Defendant(s):
3M Company and other chemical manufacturers
Jurisdiction:
U.S. District Court for the Northern District of Ohio
Year:
2024
Outcome:
- Partial settlement totaling $110 million to address PFAS contamination claims against 3M.
- Litigation continues against remaining defendants for additional damages and remediation costs.
