PFAS Lawsuit for Firefighters: AFFF MDL 2873 Update 2026

Introduction

The PFAS lawsuit for firefighters, often called the firefighting foam or AFFF lawsuit, is one of the largest mass torts in the country. It focuses on illnesses tied to a fire suppression foam known as AFFF, which firefighters and service members used for decades and which many now link to serious disease.

The lawsuit at a glance:

• The basics: Thousands of claims against manufacturers of AFFF firefighting foam, which contained toxic PFAS chemicals.
• Why it is important: These “forever chemicals” have been tied to grave health effects, including several cancers.
• Status: More than 15,000 cases are consolidated in a single federal proceeding, MDL 2873.
• Money paid so far: Defendants have agreed to pay billions to resolve water system contamination claims, and personal injury resolutions are anticipated.
• Eligible claimants: Firefighters, service members and others exposed to AFFF who later developed qualifying cancers or illnesses.

AFFF, short for Aqueous Film-Forming Foam, became the go-to tool for extinguishing dangerous liquid fuel fires. It also contained PFAS (per- and polyfluoroalkyl substances), nicknamed “forever chemicals” because they resist breakdown in the environment and in the body. PFOA and PFOS are the best-known examples, and both are highly toxic and extremely persistent. A CDC official has described PFAS as “one of the most seminal public health challenges for the next decades.”

AFFF Foam and the Health Risks of PFAS Exposure

AFFF was built for one demanding job: putting out Class B fires fueled by flammable liquids such as gasoline, jet fuel and oil. Water often fails against these fires, so AFFF relies on fluorinated surfactants that spread a film over the fuel, smothering the flames and keeping them from flaring up again.

Those surfactants are PFAS. For decades they were used without a full understanding of their effects on the body. Firefighters spraying the foam were not just using equipment; they were absorbing chemicals that bioaccumulate, building up over time and lingering in the body.

What the Science Says About Cancer

Research connecting PFAS to serious disease keeps getting stronger. A National Cancer Institute study is viewed by many experts as the most compelling evidence yet tying testicular cancer to PFAS exposure. Some legal commentators have said the new findings simply confirm what earlier evidence already showed.

Researchers have also linked PFAS to other PFAS exposure symptoms and diseases, including:

• Kidney Cancer: Rates are notably higher among people with elevated PFAS in their blood.
• Thyroid Disease and Cancer: PFAS disrupt hormones, contributing to hypothyroidism and thyroid tumors.
• Ulcerative Colitis: This chronic inflammatory bowel condition has become a central part of the litigation.
• Liver Damage: Exposure can contribute to fatty liver disease and liver cancer.

Cancer Deaths Among Firefighters

The danger to firefighters is severe. One study reports that firefighters are 60% more likely than the general public to die of cancer, with prostate cancer death rates four times higher and leukemia rates three times higher. Between 2002 and 2019, cancer caused 66% of line-of-duty deaths among career firefighters.

Tier 1 Qualifying Conditions

In the PFAS lawsuit for firefighters, the court has focused first on a “Tier 1” group of core diagnoses. If you or a family member developed one of these after working with AFFF, the claim is considered among the strongest:

1. Kidney Cancer
2. Testicular Cancer
3. Liver Cancer
4. Thyroid Cancer
5. Ulcerative Colitis
6. Thyroid Disease

Where MDL 2873 and the Firefighter PFAS Lawsuit Stand Now

The PFAS lawsuit for firefighters has been moving quickly. Most cases are consolidated in Multidistrict Litigation (MDL) 2873 before Judge Richard Gergel in the District of South Carolina.

In early 2026 the MDL held 15,216 pending cases, a 99% jump since January 2025. Much of that growth came from the “Filing Facilitation Window” that closed in late 2025, which led to a wave of new filings as claimants recognized that potential global settlement deadlines were near.

Bellwether Trials and Discovery

The litigation is at a pivotal point. Bellwether trials, the test cases that show how juries may respond to the evidence, are being prepared. Judge Gergel recently extended the deadline to choose discovery pool plaintiffs for “Tier 2 Group B” cases, which include injuries such as liver and thyroid cancer that recent research strongly ties to PFAS.

For the newest developments, see our PFAS lawsuit update today. The court has been pushing the parties to settle before the first personal injury bellwether trials, which were tentatively set for late 2025 or early 2026; check the current schedule as of this update.

Companies Named in the Firefighter PFAS Lawsuit

The defendants include some of the biggest names in chemical manufacturing, accused of knowing PFAS were toxic as far back as the 1950s and 1970s and concealing that knowledge to protect profits.

Leading defendants include:

• 3M Company: For decades the main AFFF producer; internal 1978 documents show company scientists warning PFAS were “more toxic than anticipated.”
• DuPont / Chemours / Corteva: Related companies behind much of the PFOA used in the United States.
• Tyco Fire Products: A large supplier of firefighting gear and foam.
• Kidde-Fenwal: Recently reached a $730 million settlement over its AFFF products.
• Johnson Controls and Carrier Global: Both under significant pressure to fund settlements.

Settlements So Far and What They Signal for Firefighters

A global resolution of personal injury claims has not yet arrived, but the water contamination side of the litigation has already produced record payments.

• 3M: Agreed to pay at least $10.3 billion to public water systems nationwide.
• DuPont/Chemours/Corteva: Created a $1.185 billion fund for PFAS in drinking water.
• Carrier Global: Reached a $730 million deal resolving claims against subsidiary Kidde-Fenwal.

What These Settlements Mean for Your Claim

For personal injury claimants, the water settlements are encouraging because they show defendants will pay heavily to avoid jury trials. The ranges below reflect projections circulated in the legal community, not announced settlements or guarantees; any individual claim’s value will depend on the diagnosis, exposure history and medical evidence.

Treat these figures as rough projections only. Claims backed by clear medical records and long-term occupational exposure are generally expected to land in the higher tiers.

Who Qualifies and How to File an AFFF Claim

Who can join the PFAS lawsuit for firefighters? More people than you might expect. Municipal firefighters make up the largest group of plaintiffs, but several others face high exposure.

High-Risk Occupations

• Service Members: The military used about 75% of all AFFF in the U.S., so anyone stationed at an Air Force base, on a Navy vessel or at a military airfield was probably exposed.
• Airport Rescue Firefighters: FAA rules required AFFF at airports for decades.
• Industrial Workers: Employees at refineries and chemical plants that stored large volumes of AFFF, often 20,000 to 40,000 gallons, are also at risk.

Exposure Through the Skin

Manufacturers long argued that PFAS harm required ingestion or inhalation. Newer research shows PFAS can be absorbed through the skin, which matters greatly for firefighters who handled foam or wore PFAS-treated turnout gear.

Filing Deadlines and the Discovery Rule

Many veterans and retired firefighters worry about the statute of limitations, assuming that retiring two decades ago means it is too late.

Ordinarily, a lawsuit deadline begins when an injury occurs. In toxic exposure cases like the PFAS lawsuit for firefighters, courts often apply the Discovery Rule, which delays the start of the clock until you learn, or reasonably should have learned, that AFFF caused your illness.

Because manufacturers kept the PFAS-cancer connection hidden for so long, many people are only now making the link, so older claims may still be timely. To gauge your timing and potential value, try our AFFF settlement calculator and review our PFAS cancer risk complete guide.

AFFF Lawsuit FAQs

Who is eligible to file an AFFF lawsuit?

In general, people with regular work-related AFFF exposure who were later diagnosed with an associated cancer or ulcerative colitis, including civilian and military firefighters, veterans, airport crash crews and industrial workers. Some residents near bases who drank contaminated well water may also meet PFAS lawsuit eligibility requirements.

Which cancers are tied to firefighting foam?

Kidney, testicular, liver and thyroid cancers have the strongest links, and there is also meaningful evidence on prostate cancer and leukemia. For prostate cancer, our PFAS prostate cancer guide explains where those claims stand.

How long will an AFFF settlement take?

Litigation this large takes years. The case appears to be nearing a potential global settlement, and many observers expect most personal injury claims to be resolved in the 2025-2026 period, though timing can shift. Follow our AFFF lawsuit updates for the latest.
