AFFF Firefighting Foam Lawsuit
(PFAS "Forever Chemicals")
This massive environmental contamination litigation involves PFAS chemicals from firefighting foam that have contaminated drinking water supplies across America. Tens of thousands of plaintiffs—including firefighters, military personnel, and communities near contaminated sites—are seeking compensation for cancer and other serious health conditions.
Key Takeaways
- Over 15,220 cases pending as of May 2026 with 99% growth
- $11.5+ billion in settlements reached with major manufacturers
- PFAS chemicals classified as carcinogenic (Group 1) by IARC in November 2023
- Firefighters, military personnel, and contaminated communities are primary plaintiffs
- EPA set drinking water limit at 4 parts per trillion in 2024
May 2026 Updates Latest
15,232 cases pending (19,797 total) — modest net growth as new personal injury filings continue alongside ongoing water contamination dismissals. Plaintiffs' and defendants' leadership teams remain extended through May 2026 as Judge Richard Gergel keeps the existing structure in place while the second bellwether pool advances. The previously scheduled October 2025 bellwether remains off-calendar, with the next personal-injury trial date still being negotiated. CMO 37 compliance reviews continue to trigger cure-period letters and dismissals for plaintiffs missing required fact sheets.
No personal injury settlements have been reached, but attorneys widely expect a global personal-injury resolution in 2026 or 2027 once bellwether outcomes start to come in. The selected 28 personal injury bellwether cases — 8 kidney cancer, 8 testicular cancer, 8 thyroid disease, and 4 ulcerative colitis — continue through case-specific discovery. Water-contamination settlements totaling $12.2B+ (including the DuPont/Chemours $1.185B public water suppliers fund) remain finally approved, and individual personal-injury claims are still projected at $200,000–$1,000,000+ depending on injury severity.
Key Facts (May 2026)
| Pending Actions | 15,232+ cases in federal MDL |
| Total Settlements | $11.5 billion+ (3M, DuPont/Chemours) |
| 3M Settlement | $10.3 billion over 13 years (2023) |
| IARC Classification | Group 1: Carcinogenic to humans (PFOA) |
| EPA Drinking Water Limit | 4 parts per trillion (PFOA/PFOS) |
| Presiding Judge | Hon. Richard M. Gergel (D.S.C.) |
| MDL Created | December 2018 |
| Personal Injury Claims | Still actively being filed |
November 2023: PFOA Classified as "Carcinogenic to Humans"
The World Health Organization's International Agency for Research on Cancer (IARC) upgraded PFOA to Group 1 (carcinogenic to humans)—the highest classification—based on sufficient evidence for cancer in experimental animals and strong mechanistic evidence in humans. This is the same classification as asbestos and tobacco.

Explosive Case Growth
One of the fastest-growing environmental MDLs. Case count has more than doubled in 2025, surging 100% as water contamination claims continue to be filed nationwide.

1 Understanding PFAS: The "Forever Chemicals"
PFAS (per- and polyfluoroalkyl substances) are a group of manufactured chemicals that have been used since the 1940s. They're called "forever chemicals" because the carbon-fluorine bonds that make them so effective also make them nearly indestructible—they don't break down in the environment and can accumulate in your body over time.
AFFF (Aqueous Film-Forming Foam) is a firefighting foam specifically designed to extinguish fuel-based fires. According to the EPA, AFFFs containing PFAS have been used at airports, shipyards, military bases, firefighting training facilities, chemical plants, and refineries for decades.

2 Proven Health Effects of PFAS Exposure
Multiple government health agencies have confirmed that PFAS exposure causes serious health problems. Here's what the science shows:
Cancer Links (IARC/EPA/NCI Confirmed)
Sources: IARC Monographs Vol. 135; NCI Cancer Trends Progress Report; EPA PFAS Health Understanding
From EPA Studies
- Decreased fertility in women
- High blood pressure in pregnant women
- Developmental delays in children
- Hormone interference
- Increased cholesterol/obesity risk
From CDC/ATSDR (July 2025)
- Changes in liver enzymes
- Lower antibody response to vaccines
- Pregnancy-induced hypertension
- Preeclampsia
- Small decreases in birth weight
Immune System Damage (NTP Finding)
In 2016, the National Toxicology Program concluded that both PFOA and PFOS are "presumed to be an immune hazard to humans" based on high-level evidence from animal studies showing suppressed antibody response and moderate evidence from human studies.

3 Who Has Been Exposed to PFAS?
Firefighters
According to IARC, firefighters face particularly high exposure through direct use of AFFF during training exercises and emergency response. Both inhalation and skin contact are exposure routes.
- • Airport firefighters
- • Military firefighters
- • Municipal firefighters
- • Industrial firefighters
Military Personnel
AFFF was extensively used at military bases for fire training and aircraft emergencies. The CDC/ATSDR is currently conducting exposure assessments at communities near military installations.
- • Air Force base personnel
- • Naval base workers
- • Army base firefighters
- • Coast Guard personnel
Communities Near Contaminated Sites
PFAS have contaminated groundwater and drinking water supplies near locations where AFFF was used. The main exposure pathway for the general public is drinking contaminated water.
- • Near military bases
- • Near airports
- • Near refineries
- • Near training facilities
Industrial Workers
Workers at PFAS manufacturing facilities, those using PFAS in production, and waste management workers handling PFAS-contaminated materials face occupational exposure.
4 The Litigation: MDL-2873
The Judicial Panel on Multidistrict Litigation consolidated AFFF cases in South Carolina because they share common questions about whether PFAS-containing firefighting foams contaminated groundwater and caused harm to people and communities.
5 Major Settlements
3M agreed to pay $10.3 billion over 13 years to settle claims from public water systems. This is one of the largest environmental settlements in U.S. history and will help fund water treatment and remediation efforts.
DuPont, Chemours, and Corteva agreed to pay $1.185 billion to settle water contamination claims from municipalities and water districts.
Important: These settlements primarily resolved claims from water utilities. Personal injury claims from individuals diagnosed with cancer and other health conditions are still being actively litigated.
6 EPA Drinking Water Standards (April 2024)
In April 2024, the EPA finalized the first-ever national drinking water standards for PFAS. These regulations set strict limits and require action by water systems.
Maximum Contaminant Levels (MCLs)
| Compound | Goal (MCLG) | Enforceable Limit |
|---|---|---|
| PFOA | Zero | 4.0 parts per trillion |
| PFOS | Zero | 4.0 parts per trillion |
| PFHxS | 10 ppt | 10 parts per trillion |
| PFNA | 10 ppt | 10 parts per trillion |
| GenX (HFPO-DA) | 10 ppt | 10 parts per trillion |

Public water systems must complete initial PFAS monitoring
Treatment solutions must be implemented if levels exceed MCLs
7 Do You Qualify for Compensation?
You may be eligible to file a claim if you have documented PFAS exposure AND have been diagnosed with a linked health condition.
Exposure Evidence Needed
- Used AFFF as a firefighter or military personnel
- Lived or worked near a military base, airport, or industrial facility using AFFF
- Drank water from a contaminated municipal supply or private well
- Blood tests showing elevated PFAS levels
Qualifying Diagnoses
Medical Testing: In July 2022, the National Academies of Sciences recommended that doctors offer PFAS blood testing to patients with likely elevated exposure history. Ask your doctor about testing if you believe you've been exposed.
