Last updated: June 11, 2026

AFFF firefighting foam lawsuits involve allegations that exposure to certain firefighting foams containing PFAS chemicals may be associated with contaminated water, cancer-related illnesses, and other serious health concerns. These cases often involve firefighters, military personnel, airport workers, industrial sites, and communities located near contaminated water sources.

AFFF claims are one of the major PFAS-related lawsuit categories. Some cases focus on occupational exposure among firefighters and military personnel, while others involve alleged groundwater or drinking water contamination near training sites, airports, military bases, or industrial facilities.

AFFF Lawsuit Update: Where the Litigation Stands (June 2026)

Most federal AFFF lawsuits are consolidated in a multidistrict litigation, MDL 2873, in the U.S. District Court for the District of South Carolina before Judge Richard M. Gergel. As of June 2026, more than 15,000 cases were pending in the MDL, a figure that has roughly doubled since early 2025 as new personal injury filings continue to arrive.

The most important distinction for individual readers is between the water-system track and the personal-injury track. The large settlements widely reported in the news resolved claims brought by public water systems, including a 3M settlement valued at up to approximately $10.3 billion, a DuPont, Chemours, and Corteva settlement of approximately $1.185 billion, and a Carrier Global settlement of approximately $730 million connected to the Kidde-Fenwal bankruptcy. Those funds go toward water treatment and monitoring, not to individuals diagnosed with cancer or other conditions.

For individual personal injury claims, no global settlement had been announced as of June 2026. The first personal injury bellwether trial, originally scheduled for October 2025, was taken off the calendar after a surge of new filings, and the court has been working through case management and evidentiary requirements before setting new trial dates. The court also held a Science Day in mid-2025 focused on expert presentations about thyroid and liver cancer causation questions, which helps frame what scientific testimony may be admissible as bellwether trials approach.

In practical terms, people searching for an individual AFFF or PFAS settlement update should understand that the personal injury track remains in active pretrial litigation. Settlement news involving billions of dollars has so far involved water providers and government entities, and individual claim outcomes will depend on how bellwether trials and any future negotiated resolutions develop.

What Is AFFF Firefighting Foam?

AFFF, or aqueous film-forming foam, is a firefighting foam used to extinguish fuel-based fires involving gasoline, jet fuel, and other flammable liquids. It has been used for decades by military bases, airports, industrial facilities, and firefighting departments because of its effectiveness in high-risk fire settings.

Many AFFF products have been alleged to contain PFAS chemicals, sometimes called "forever chemicals," because they can persist in the environment for long periods and may accumulate in water, soil, and living systems.

Why People Research AFFF Lawsuits

Many lawsuits allege that PFAS chemicals in firefighting foam contaminated groundwater and drinking water near training sites, military bases, airports, industrial locations, and surrounding communities. Some plaintiffs claim that long-term occupational or environmental exposure may have increased the risk of serious illness.

These cases often examine contamination evidence, product design, corporate knowledge, warnings, cleanup issues, and the connection between PFAS exposure and later health concerns.

For a more current overview of how PFAS water claims, public water system settlements, AFFF litigation, and individual injury claims may overlap, read our PFAS water contamination lawsuit update.

AFFF claims often overlap with Toxic Water Contamination Lawsuits, Environmental Contamination Lawsuits, Chemical Exposure Lawsuits, and Toxic Exposure Lawsuits.

Firefighter and Military Occupational Exposure

Firefighters and military service members make up a large share of the individual plaintiffs in AFFF litigation. Career and volunteer firefighters allege exposure during training exercises, equipment testing, and emergency response, often over many years. Military firefighters and service members allege exposure during foam drills, crash response, and hangar fire suppression at bases where AFFF was standard equipment for decades.

Occupational claims tend to focus on different evidence than community water cases. Work history, training records, the specific foam products used at a station or base, protective equipment practices, and the timing of a later diagnosis can all matter. Firefighter unions and advocacy organizations have also pushed for broader PFAS protections, including presumptive coverage laws in some states that treat certain cancers as occupational illnesses for firefighters.

Military service members face an additional wrinkle. Claims against the government itself are generally limited, so military AFFF cases typically proceed against the foam manufacturers rather than the armed services. Veterans who lived or worked at bases with documented PFAS contamination may also research related water contamination claims.

Is AFFF Being Recalled or Phased Out?

There has been no traditional consumer recall of AFFF, but the foam is being phased out of major institutional use, and the phase-out is one reason public attention on AFFF has grown. The National Defense Authorization Act for Fiscal Year 2020 required the Department of Defense to stop purchasing PFAS-based AFFF and to end its use at military installations, with a statutory deadline of October 1, 2024 and up to two one-year waivers.

The Department exercised both waivers, extending some AFFF use to October 1, 2026 while it transitions roughly 1,000 facilities and more than 6,000 mobile assets to fluorine-free alternatives. A military specification for fluorine-free foam, known as F3, was published in January 2023, and multiple qualified F3 products are now available. Many civilian airports and state and local fire departments have been making similar transitions, and a number of states have restricted or banned PFAS-based foam for training.

For litigation purposes, the phase-out does not itself establish that any product caused any particular illness. It does mean that AFFF use is winding down at the institutions that historically used it most, while disposal of legacy foam stocks and cleanup of contaminated sites remain ongoing issues.

Who May Be Affected

• Firefighters involved in training or emergency response
• Military personnel working near foam training areas or base fire operations
• Airport workers and emergency response teams
• Industrial workers at sites using foam-based fire suppression systems
• Communities located near contaminated groundwater or drinking water sources

Health Concerns Discussed in These Cases

• Kidney cancer
• Testicular cancer
• Immune system concerns
• Thyroid-related conditions
• Liver-related concerns
• Other health issues examined in PFAS-related litigation

Health-related allegations in AFFF lawsuits can depend on the type of exposure, length of exposure, medical history, diagnosis, and available scientific evidence. These pages are intended to help readers understand the topics people commonly research, not to determine whether a specific diagnosis was caused by PFAS exposure.

Common Sources of Alleged Exposure

• Firefighter training exercises
• Military base firefighting drills
• Airport emergency response training
• Industrial fire suppression systems
• Contaminated groundwater near testing or training sites
• Long-term community exposure near foam-use locations

Types of Claims Involved

• Environmental contamination claims
• Failure-to-warn allegations involving PFAS risks
• Product liability claims
• Negligence allegations related to chemical manufacturing or safety
• Water contamination and cleanup-related claims

Some contamination lawsuits also involve PFAS water contamination, where communities allege that long-term exposure to these chemicals may be linked to serious health risks.

Other claims may focus on occupational exposure rather than community water contamination. In those situations, work history, training history, job duties, protective equipment, and product identification may become important.

Why These Cases Can Be Complex

AFFF lawsuits can involve multiple layers of scientific and legal issues, including contamination history, water testing, occupational exposure, diagnosis, latency periods, and evidence about PFAS-related risks. Some cases focus on personal injury claims, while others involve property damage, community contamination, or public water issues.

In some situations, the questions focus on one workplace or one training site. In others, the issues may involve larger contamination zones, multiple possible exposure pathways, public notices, site investigations, and long timelines between exposure and diagnosis.

These claims may also involve different categories of defendants, including product manufacturers, industrial operators, site owners, or other entities depending on the alleged source of exposure and the claim being evaluated.

One distinction causes more confusion in AFFF litigation than any other. The large, widely reported PFAS settlements went to public water systems and municipalities to fund water treatment, not to individual people with cancer or other PFAS-linked illnesses. The personal-injury track for individuals is on a separate path and has not produced a global settlement. If you have a personal-injury claim, news of a multibillion-dollar settlement may not mean what it appears to mean for your situation. Our guide on how mass tort cases are structured and resolved explains this water-utility versus personal-injury split in plain terms, and the Where Does My Lawsuit Stand? tracker shows what phase the AFFF personal-injury track is in right now and what the next milestone is.
