What PFAS Are
PFAS — per- and polyfluoroalkyl substances — are a family of synthetic chemicals used for decades in products from nonstick pans to stain-resistant fabrics to firefighting foam. They are nicknamed “forever chemicals” because they do not break down naturally and build up in the environment and in people’s bodies. PFAS have contaminated drinking water for millions of Americans, and research has linked exposure to health problems including certain cancers, liver and immune-system effects, and developmental harm. Public water systems have faced enormous costs to filter these chemicals out.
Manufacturers, plaintiffs alleged, knew of the risks for years while the chemicals spread widely.
The Settlements
In 2023, 3M — a major PFAS maker — agreed to pay up to $10.3 billion over 13 years to help public water systems across the US test for and remove PFAS, in what is described as the largest environmental contamination settlement in US history. Around the same time, DuPont and its related companies Chemours and Corteva agreed to a separate $1.185 billion settlement with public water systems. Crucially, these deals compensate water utilities for cleanup; they are distinct from personal-injury cases, in which individuals allege PFAS exposure — often from firefighting foam — caused their illness, which are proceeding separately.
So “the PFAS settlement” is really about paying to clean the water supply, not directly compensating people for health harms.
What to Know
If you are concerned about PFAS in your tap water, you can check your utility’s water-quality reports and, as federal limits on PFAS in drinking water take effect, expect more testing and treatment; certified home filters (such as reverse-osmosis or activated-carbon systems rated for PFAS) can reduce exposure. People who believe PFAS exposure harmed their health — particularly firefighters and those near contamination sources — are the subject of separate injury litigation and should seek qualified legal and medical advice.

3M PFAS Water Lawsuit: The $10 Billion 'Forever Chemicals' Settlement: Frequently Asked Questions
Answers to the most common questions about this case and your legal options.
What is the 3M PFAS water settlement?
In 2023 3M agreed to pay up to $10.3 billion over 13 years to help US public water systems test for and remove PFAS 'forever chemicals' — the largest environmental settlement in US history. DuPont, Chemours and Corteva added a separate $1.185 billion settlement.
Does the settlement pay individuals for health harm?
No. These settlements compensate public water systems for cleanup. Personal-injury cases, in which individuals allege PFAS exposure (often from firefighting foam) caused illness, are separate litigation.
How can I reduce PFAS in my water?
Check your utility's water-quality reports, expect more testing as federal PFAS limits take effect, and consider a certified home filter (reverse-osmosis or activated-carbon systems rated for PFAS) to reduce exposure.
