3M & DuPont PFAS "Forever Chemicals" Water Contamination Litigation
Case Overview
Per- and polyfluoroalkyl substances (PFAS), commonly known as 'forever chemicals,' are a class of man-made compounds used for decades in non-stick cookware, firefighting foam, food packaging, and countless industrial applications. 3M and DuPont were among the primary manufacturers of PFAS compounds, and their chemicals have been detected in the drinking water supplies of thousands of communities across the United States. Scientific studies have linked PFAS exposure to serious health conditions including kidney cancer, testicular cancer, thyroid disease, immune system disorders, and developmental problems in children. The EPA has classified several PFAS compounds as hazardous and in 2024 set the first-ever enforceable maximum contaminant levels for PFAS in public drinking water.
The multidistrict litigation consolidates thousands of lawsuits filed by public water systems, municipalities, and individual plaintiffs seeking compensation for the cost of filtering PFAS from water supplies and for personal health injuries. In 2023, 3M agreed to pay up to $10.3 billion over 13 years to settle claims from public water utilities, while DuPont, Chemours, and Corteva agreed to a separate $1.185 billion settlement. Despite these landmark agreements, individual personal injury claims and suits by states and private well owners remain active. The litigation is widely regarded as one of the most consequential environmental mass tort actions in American legal history.
Who May Qualify
Public water systems and municipalities whose water supplies tested positive for PFAS contamination; individuals who consumed PFAS-contaminated water and developed related health conditions such as kidney or testicular cancer, thyroid disease, or ulcerative colitis; and private well owners with confirmed PFAS contamination.
Frequently Asked Questions
Did 3M settle the PFAS water contamination lawsuit?
Yes. In June 2023, 3M agreed to pay up to $10.3 billion over 13 years to settle claims from U.S. public water systems affected by PFAS contamination. A separate $1.185 billion settlement was reached with DuPont, Chemours, and Corteva. Individual personal injury claims are still being litigated.
Can I sue if PFAS chemicals made me sick?
Potentially yes. If you were exposed to PFAS-contaminated drinking water and developed a related illness — such as kidney cancer, testicular cancer, thyroid disease, or ulcerative colitis — you may have a personal injury claim. These cases are separate from the water utility settlements and are still actively being filed.
What health problems are linked to PFAS 'forever chemicals'?
PFAS exposure has been scientifically linked to kidney and testicular cancer, thyroid disease, high cholesterol, immune system suppression, pregnancy complications including preeclampsia, and developmental issues in children. The EPA has recognized these risks and set new drinking water standards for PFAS in 2024.
