AFFF Firefighting-Foam Litigation Tops 15,240 Injury Claims as Trials Slip Again

The sprawling federal litigation over aqueous film-forming foam (AFFF) — the PFAS-laden firefighting foam used for decades on military bases, at airports, and at industrial fire-training sites — has swelled to roughly 15,240 personal-injury claims as of June 2026, part of nearly 19,800 total cases consolidated in Multidistrict Litigation 2873 before Judge Richard Gergel in the U.S. District Court for the District of South Carolina. Yet for all that volume, not a single personal-injury case has reached a jury: the first bellwether trial, set for October 20, 2025, was pulled from the calendar after the court discovered a large backlog of unfiled claims, and no new trial date has been set. The AFFF docket is a parallel track to the more familiar Camp Lejeune litigation — but where Camp Lejeune turns on a single base and a special federal statute, AFFF is a product-liability fight against the chemical manufacturers themselves, and it touches PFAS contamination at hundreds of sites nationwide.

Two Tracks: Water Systems vs. Injured People

The AFFF litigation has always run on two distinct tracks, and conflating them is the most common source of confusion.

The public water-system track — claims by utilities whose source water was contaminated by AFFF runoff — has largely settled. In 2023, 3M agreed to pay up to roughly $10.3 billion (later valued by some accountings as high as $12.5 billion) to resolve drinking-water claims from public systems, and DuPont, its spinoff Chemours, and Corteva agreed to a separate $1.185 billion fund, with Chemours contributing 50% and DuPont and Corteva splitting the rest. That DuPont-side settlement is still awaiting final approval from the South Carolina court. These funds reimburse utilities for the cost of installing treatment — granular activated carbon, ion exchange, or reverse osmosis — to strip PFAS out of finished water.

The personal-injury track is the one still unresolved. These are claims by firefighters, military service members, airport workers, and residents who drank PFAS-contaminated water and later developed cancer or other diseases. None of the manufacturers has agreed to a global personal-injury settlement, and it is this track — not the water-utility funds — whose bellwether trials keep slipping.

Why the Trials Keep Slipping

Bellwether trials are test cases: a handful of representative claims tried before juries to establish how the wider inventory might be valued. The AFFF MDL selected its first personal-injury bellwethers around kidney cancer, the condition with the strongest epidemiological link to PFAS exposure, with liver cancer and thyroid cancer among the newer conditions added to later trial groups.

The October 2025 kidney-cancer trial was meant to be the first real signal. It came off the calendar when the court found a substantial volume of cases filed administratively but not yet formally docketed — a backlog large enough that Judge Gergel began requiring claimants to produce proof of medical diagnosis and exposure evidence before the litigation advances, rather than letting unsupported filings inflate the count. That documentation push mirrors the bottleneck playing out in Camp Lejeune, where hundreds of thousands of filed claims dwarf the comparatively small number that carry the medical and proof-of-presence records the cases actually require.

The practical effect is delay. Industry observers had expected personal-injury bellwethers to get underway in 2026; as of mid-June, no firm date is on the calendar, and the causation and expert-evidence fights that precede any trial remain unresolved.

What’s Allegedly Linked to AFFF Exposure

The MDL is pursuing a defined set of personal-injury conditions allegedly connected to PFAS exposure from firefighting foam. Kidney cancer anchors the litigation as the lead bellwether condition, with testicular cancer, thyroid disease, liver cancer, and ulcerative colitis among the other conditions courts and regulators have most often associated with PFAS. Epidemiological studies have associated long-term PFAS exposure with these outcomes, though causation in any individual case is exactly what the bellwether process is designed to test.

For the underlying chemistry and health context, our PFAS contaminant profile and PFAS explained guide cover how these “forever chemicals” persist in the body and the environment, and why even low concentrations draw regulatory scrutiny.

How Much Individual Claims Might Be Worth

There is no global personal-injury settlement, so any figure is an estimate. Industry sources peg potential compensation in the range of roughly $75,000 to $500,000 per claim, scaling with the severity of the diagnosis and the strength of the exposure proof — a firefighter with decades of documented foam exposure and a Tier-1 cancer would sit at the high end; a brief, poorly documented exposure with a less-linked condition near the low end. Those numbers are speculative until bellwether verdicts establish real benchmarks, which is precisely why the trial delays matter: without verdicts, neither side has a firm anchor for negotiating the broader inventory.

The Military-Base Dimension

AFFF’s heaviest footprint is on and around military installations, where the foam was used in fire-training exercises and emergency response for half a century. PFAS from those exercises seeped into groundwater, contaminating both base supply wells and private wells in surrounding communities. The Defense Department has identified contamination at hundreds of current and former installations, and in several cases remediation timelines have stretched far into the future — in Washington state, two base cleanups originally slated for completion in 2026 now carry target dates of 2032 and 2034.

This is where AFFF overlaps with, but remains legally distinct from, Camp Lejeune. Camp Lejeune claimants sue under the Camp Lejeune Justice Act, a special federal statute, over solvent contamination (TCE, PCE, and other VOCs). AFFF claimants sue the foam manufacturers under product-liability theory over PFAS. The Red Hill, Hawaii fuel-leak case is a third, separate military water-contamination track. They share a theme — service members and families exposed to contaminated base water — but different defendants, different chemicals, and different legal machinery.

What This Means for Water Utilities and Residents

For public water systems, the live issue is a deadline, not a trial. Utilities must file claims against the settlement funds to recover treatment costs — the DuPont/Chemours/Corteva fund carries a claims deadline of June 30, 2026, and the 3M fund a deadline of July 31, 2026. Systems that miss those windows forfeit their share. Our coverage of the PFAS settlement deadlines facing utilities and the DuPont action-fund June deadline breaks down what’s at stake, and the NRDC warning that settlement money could “evaporate” explains why so many small systems risk leaving money on the table.

For residents, the litigation is a lagging indicator, not a real-time safety tool. If you live near a military base, airport, or industrial fire-training site, the more useful step is to find out what’s actually in your water now:

On a public system: ask your utility for its UCMR 5 PFAS monitoring results or check your annual Consumer Confidence Report — our guide to understanding your CCR explains how to read it.
On a private well near a base: PFAS is not covered by routine well panels and must be tested specifically. See our private wells and PFAS guide and the well water testing guide for what to order.
To reduce PFAS at the tap: certified reverse-osmosis and high-quality activated-carbon systems are the most effective household options — our best reverse osmosis systems and best under-sink water filters guides cover NSF-certified units.

What Comes Next

The next inflection point is whichever bellwether the court finally sends to trial. A plaintiff verdict would pressure the manufacturers toward a global personal-injury settlement and set valuation anchors for tens of thousands of pending claims; a defense verdict would slow the litigation and weaken settlement leverage. Until then, the AFFF MDL remains the largest unresolved PFAS-injury fight in the country — and a reminder that the federal rollback of PFAS drinking-water limits is unfolding even as the legal system works through the consequences of decades of exposure.

How WaterVerge Tracks This

WaterVerge integrates EPA UCMR 5 PFAS monitoring data into city pages, flagging utilities where PFOA, PFOS, and other forever chemicals were detected in finished water. AFFF litigation outcomes don’t change what’s in your tap today, but they shape how aggressively utilities treat for PFAS in the years ahead. Search your city to see whether PFAS has been detected in your water system.
