October 2026 Updates Latest
15,264 cases pending (19,840 total), unchanged from the September report. The October 2025 personal-injury bellwether trial was vacated, and no new personal-injury trial date has been set, according to 3M's latest quarterly filing. Court-ordered settlement talks continue with a court-appointed mediator. Proposals for selecting the Group B personal-injury bellwether cases (thyroid disease and ulcerative colitis) are due November 20, 2026. CMO 37 compliance reviews continue to trigger cure-period letters and dismissals for plaintiffs missing required fact sheets.
DuPont, Chemours and Corteva settle North Carolina's PFAS claims for $455 million (Sep 10, 2026)
On September 10, 2026, DuPont, Chemours and Corteva settled with North Carolina and 11 local entities for $455 million over 15 years (present value about $355 million). The deal resolves claims over the Fayetteville Works plant and the State's other PFAS claims, including from the use of AFFF. Of the total, $18 million is for non-Fayetteville claims, and no more than $14.4 million is for AFFF. It is not a personal-injury settlement.
Settlement talks & the Group B bellwether schedule
No personal injury settlements have been reached. According to 3M's latest quarterly filing, court-ordered settlement talks continue with a court-appointed mediator, and a special master was appointed in June 2026. CMO 38 (June 3, 2026) requires one action per personal-injury plaintiff. Under CMO 26O (July 30, 2026), proposals for selecting the Group B personal-injury bellwether cases (thyroid disease and ulcerative colitis) and for expert discovery are due November 20, 2026. Under CMO 33F (August 31, 2026), responses to Rule 702 expert motions on thyroid and liver cancer are due November 20, 2026, with replies due January 22, 2027. More than $11 billion in water-provider settlements (including the DuPont/Chemours $1.185B public water suppliers fund) remain finally approved.

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.

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.
On September 10, 2026, DuPont, Chemours, and Corteva settled with North Carolina and 11 local entities for $455 million over 15 years (present value about $355 million). The deal resolves claims over the Fayetteville Works plant and the State's other PFAS claims, including from AFFF use. Only $18 million is for non-Fayetteville claims, and no more than $14.4 million is for AFFF. It is not a personal-injury settlement.
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. In May 2026, the EPA proposed changes to these standards (see below). The proposal is not final.
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 (proposed for rescission) |
| PFNA | 10 ppt | 10 parts per trillion (proposed for rescission) |
| GenX (HFPO-DA) | 10 ppt | 10 parts per trillion (proposed for rescission) |
Source: EPA Safe Drinking Water Act PFAS Regulations, April 2024
May 2026 proposal (not final): On May 18, 2026, the EPA proposed keeping the 4.0 ppt limits for PFOA and PFOS, with an optional two extra years (to 2031) to comply, and rescinding the limits for PFHxS, PFNA, GenX, and the hazard index. These changes are proposed, not final.
Public water systems must complete initial PFAS monitoring
Treatment solutions must be implemented if levels exceed MCLs. The May 2026 proposal would allow an optional two extra years, to 2031, for PFOA and PFOS.
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.
