If you or a loved one served as a firefighter, worked on a military base, or lived near a facility that used firefighting foam — and were later diagnosed with cancer or thyroid disease — you may be entitled to significant compensation. Aqueous film-forming foam (AFFF) lawsuits are among the largest mass tort cases in the United States, with billions of dollars already set aside for victims. This guide explains what AFFF lawsuits are, who qualifies, how much compensation you may receive, and how to file a claim in 2026.
What Is AFFF?
AFFF (aqueous film-forming foam) is a fire-suppressing foam used since the 1970s to extinguish fuel-based fires — jet fuel, gasoline, oil, and chemical fires. It was used extensively by:
- Military bases: The U.S. Department of Defense required AFFF at hundreds of bases for training exercises and emergency response. Air Force, Navy, Army, and Marine Corps bases all used it.
- Fire departments: Municipal and airport fire departments used AFFF for fuel fires, vehicle fires, and training drills.
- Airports: The FAA required AFFF at commercial airports for crash rescue operations.
- Industrial facilities: Oil refineries, chemical plants, and fuel storage facilities used AFFF for fire suppression systems.
The problem: AFFF contains PFAS (per- and polyfluoroalkyl substances) — synthetic chemicals nicknamed "forever chemicals" because they do not break down in the environment or the human body. The two most dangerous PFAS in AFFF are PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonic acid). These chemicals seeped into soil and groundwater around bases and training sites, contaminating drinking water and exposing millions of people.
The AFFF Lawsuits: What Happened?
Manufacturers including 3M, DuPont, Chemours, and others produced AFFF containing PFAS for decades. Lawsuits allege that these companies knew — or should have known — about the health dangers of PFAS as early as the 1970s, but failed to warn firefighters, military personnel, and the public.
Key developments in the AFFF litigation:
- MDL No. 2873: The AFFF multidistrict litigation in the U.S. District Court for the District of South Carolina consolidates thousands of personal injury and water contamination claims. It is one of the largest MDLs in U.S. history.
- Water contamination settlements: In 2023, 3M agreed to pay up to $12.5 billion over 13 years to resolve claims by public water systems contaminated with PFAS. DuPont and Chemours agreed to a $1.19 billion settlement for similar claims.
- Personal injury claims: Individual lawsuits by firefighters, military personnel, and residents exposed to AFFF-contaminated water are proceeding through the MDL. Bellwether trials — test cases that help set settlement values — began in 2024 and continue through 2026.
- Firefighter settlements: Several manufacturers have reached settlements with firefighters and their families for personal injury claims. More settlements are expected as bellwether trials progress.
- EPA regulations: In 2024, the EPA set the first-ever legally enforceable drinking water standards for PFAS (4 parts per trillion for PFOA and PFOS), strengthening the scientific basis for AFFF claims.
The AFFF litigation is still active in 2026. New claims are being filed, and the settlement landscape continues to evolve. If you were exposed to AFFF, now is the time to explore your legal options.
Health Conditions Linked to AFFF Exposure
Scientific research — including studies by the EPA, the Agency for Toxic Substances and Disease Registry (ATSDR), and the National Academies of Sciences — has linked PFAS exposure to serious health conditions. The strongest links are for:
- Kidney cancer: One of the most strongly linked conditions. Studies show a clear dose-response relationship between PFOA exposure and kidney cancer risk.
- Testicular cancer: Another cancer strongly associated with PFOA exposure, particularly among firefighters and military personnel.
- Thyroid disease: PFAS disrupts thyroid function, causing hypothyroidism, hyperthyroidism, and thyroid cancer.
- Ulcerative colitis: Chronic inflammatory bowel disease linked to PFOA exposure.
- Liver damage: PFAS exposure can cause liver enzyme changes, fatty liver disease, and liver cancer.
- Immune system suppression: Reduced vaccine response, increased susceptibility to infections.
- Preeclampsia and pregnancy complications: PFAS exposure during pregnancy increases risks of preeclampsia, low birth weight, and developmental delays.
- High cholesterol: PFAS raises LDL cholesterol levels, increasing cardiovascular risk.
- Bladder cancer, prostate cancer, and leukemia: Emerging research links PFAS to additional cancers; these claims are increasingly accepted in AFFF litigation.
If you were exposed to AFFF and diagnosed with any of these conditions, you may have a valid claim — even if your diagnosis was years ago.
Who Qualifies for an AFFF Lawsuit?
You may qualify to file an AFFF lawsuit if you meet these criteria:
- Exposure: You were exposed to AFFF or PFAS-contaminated water through one or more of the following:
- Worked as a firefighter (military or civilian) and used or trained with AFFF.
- Served or worked at a military base where AFFF was used.
- Lived near a military base, airport, or industrial facility that used AFFF and drank contaminated water.
- Worked at an airport, oil refinery, chemical plant, or fire training facility where AFFF was used.
- Lived in a community with PFAS-contaminated drinking water linked to AFFF use.
- Diagnosis: You were diagnosed with a qualifying health condition (kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, liver damage, or another PFAS-linked condition).
- Timing: Your diagnosis occurred after your AFFF exposure. There is no minimum exposure period — even relatively brief exposure can support a claim if the science links it to your condition.
Who can file:
- Firefighters: Military and civilian firefighters who used AFFF in training or emergency response.
- Military personnel and veterans: Service members stationed at bases where AFFF was used.
- Airport workers: Crash rescue personnel, fuel handlers, and airport firefighters.
- Residents: People who lived near contaminated bases or facilities and drank PFAS-contaminated water.
- Family members: In wrongful death cases, spouses, children, and dependents of deceased victims can file on their behalf.
Important: You do not need to prove exactly how much AFFF you were exposed to. Your lawyer will gather evidence — service records, employment records, water testing data, and medical records — to establish your exposure and link it to your diagnosis.
Compensation in AFFF Lawsuits
AFFF lawsuits seek compensation for the full impact of PFAS exposure on your life. Depending on your case, you may recover:
Economic Damages
- Medical expenses: Past and future costs of treatment — surgery, chemotherapy, radiation, medications, ongoing monitoring, and specialist care.
- Lost wages: Income lost due to illness, treatment, and recovery.
- Loss of earning capacity: Reduced ability to work or earn income in the future.
- Out-of-pocket costs: Travel for treatment, home care, medical equipment, and other expenses.
Non-Economic Damages
- Pain and suffering: Physical pain, discomfort, and emotional distress caused by your illness.
- Emotional distress: Anxiety, depression, PTSD, and fear related to your diagnosis and prognosis.
- Loss of enjoyment of life: Inability to participate in activities, hobbies, and family life as before.
- Loss of consortium: Impact on your relationship with your spouse or partner.
Punitive Damages
In cases where manufacturers are found to have knowingly concealed PFAS dangers, courts may award punitive damages — additional compensation intended to punish wrongdoing and deter future misconduct. Punitive damages can be substantial in AFFF cases.
Wrongful Death Damages
If a loved one died from a PFAS-linked condition, surviving family members may recover funeral expenses, loss of financial support, loss of companionship, and the decedent's pain and suffering before death.
AFFF Settlement Values in 2026
Settlement amounts in AFFF cases vary widely based on the severity of the illness, the strength of the exposure evidence, the plaintiff's age, and the jurisdiction. Based on bellwether trials and settlements to date:
- Kidney cancer / testicular cancer: $200,000 – $1,000,000+ per case, depending on stage, treatment, and long-term impact.
- Thyroid disease / thyroid cancer: $100,000 – $500,000+, depending on severity and whether surgery or lifelong medication is required.
- Ulcerative colitis: $150,000 – $750,000+, depending on severity, surgeries, and ongoing treatment needs.
- Liver damage / liver cancer: $200,000 – $1,000,000+, depending on severity and prognosis.
- Other conditions: Amounts vary based on the specific condition, treatment costs, and impact on quality of life.
- Wrongful death: $500,000 – $2,000,000+, depending on the decedent's age, earnings, and family circumstances.
Water contamination claims: Property owners and water providers with PFAS-contaminated water may recover remediation costs, property devaluation, and medical monitoring expenses. These claims are often handled separately from personal injury claims.
Important note: These are estimates based on publicly reported settlements and bellwether results. Your actual settlement depends on the specifics of your case. An experienced AFFF lawyer can evaluate your case and provide a more accurate estimate.
Individual Lawsuit vs. Class Action vs. MDL
AFFF claims are handled through the multidistrict litigation (MDL) process — not as a traditional class action. Here is the difference:
- Individual lawsuit: You file your own case with your own lawyer. Your case is evaluated on its own merits, and you control settlement decisions.
- Class action: A single lawsuit represents a large group. Individual plaintiffs have little control, and settlements are divided among all members. AFFF personal injury claims are generally NOT handled as class actions.
- MDL (Multidistrict Litigation): Your individual case is consolidated with thousands of similar cases for pretrial proceedings (discovery, expert testimony, bellwether trials). You keep your own lawyer and your own case. If your case does not settle during the MDL, it returns to your home court for trial. This is how AFFF personal injury claims are handled.
The MDL process is efficient — it avoids duplicative discovery and allows bellwether trials to establish settlement values — while preserving your right to an individual recovery based on your unique circumstances.
How to File an AFFF Lawsuit: 7 Steps
- Contact an AFFF lawyer (free consultation): Most AFFF lawyers offer free case evaluations. They will review your exposure history, diagnosis, and medical records to determine if you have a valid claim. There is no cost and no obligation.
- Gather evidence: Your lawyer will help you collect:
- Service records (DD-214 for veterans) or employment records showing your role and location.
- Medical records documenting your diagnosis and treatment.
- Proof of residence near a contaminated site (if applicable).
- Water testing data (your lawyer can obtain this from public records and EPA databases).
- Any documentation of AFFF use at your base or facility.
- File your complaint: Your lawyer files a complaint in federal court. Your case is transferred to the AFFF MDL in South Carolina for consolidated pretrial proceedings.
- Discovery: Both sides exchange evidence — documents, depositions, and expert reports. Your lawyer handles this process. You may be asked to provide a deposition (sworn testimony about your exposure and illness).
- Expert review: Medical and scientific experts review your case to confirm the link between PFAS exposure and your condition. This is a critical step — experienced AFFF lawyers work with top experts in toxicology, epidemiology, and oncology.
- Settlement negotiation or bellwether trial: Most AFFF cases settle before trial. Your lawyer negotiates with the defendants on your behalf. If your case is selected as a bellwether, it may go to trial — which can set the settlement value for similar cases.
- Receive compensation: If your case settles or you win at trial, you receive compensation. Your lawyer deducts their contingency fee (typically 33–40%) and case costs from the settlement. You pay nothing upfront.
Statute of Limitations: Don't Wait
Every state has a statute of limitations — a deadline for filing a lawsuit. For AFFF claims, the clock typically starts when you knew (or should have known) that your illness was caused by PFAS exposure. Deadlines vary by state:
- Most states: 2–3 years from diagnosis or discovery of the PFAS link.
- Some states: As short as 1 year or as long as 6 years.
- Discovery rule: In many states, the clock starts when you discover (or reasonably should have discovered) that PFAS caused your illness — not when you were exposed. This is important because PFAS health effects may not appear for years or decades after exposure.
- Wrongful death: The deadline for wrongful death claims is typically 1–3 years from the date of death.
Do not wait. If you were exposed to AFFF and diagnosed with a qualifying condition, contact an AFFF lawyer immediately to protect your rights. Missing the deadline means losing your right to compensation forever.
How Much Does an AFFF Lawyer Cost?
AFFF lawyers work on a contingency fee basis:
- No upfront cost: You pay nothing to hire the lawyer or file your case.
- No hourly fees: The lawyer is paid a percentage of your settlement or verdict — typically 33–40%.
- No win, no fee: If you do not recover compensation, you owe the lawyer nothing (except possibly case costs, which many firms also waive if you lose).
- Free consultation: The initial case evaluation is always free.
This arrangement means anyone — regardless of financial situation — can pursue an AFFF claim. The lawyer assumes the financial risk; you pay only if you win.
How to Choose the Right AFFF Lawyer
Not all personal injury lawyers handle AFFF cases. Look for:
- Mass tort experience: Your lawyer should have specific experience with AFFF / PFAS litigation, not just general personal injury.
- MDL involvement: Ask whether the firm is actively involved in the AFFF MDL — firms on the plaintiffs' steering committee have insider knowledge of the litigation.
- Resources: AFFF cases require significant resources — expert witnesses, scientific research, and extensive discovery. Choose a firm with the capacity to handle complex mass tort litigation.
- Track record: Ask about the firm's results in AFFF and other mass tort cases (Roundup, talc, Zantac, etc.).
- Communication: Your lawyer should explain the process clearly, update you regularly, and answer your questions promptly.
- No upfront fees: Reputable AFFF lawyers work on contingency. Avoid any firm that asks for payment upfront.
Common Mistakes to Avoid
- Waiting too long: Statutes of limitations are strict. Contact a lawyer as soon as possible after diagnosis.
- Assuming you don't qualify: Many people underestimate their exposure. If you served on a military base, worked as a firefighter, or lived near a contaminated site, you may qualify — even if you were not directly handling AFFF.
- Trying to handle it alone: AFFF litigation is complex — involving scientific evidence, federal court procedures, and MDL rules. An experienced lawyer is essential.
- Signing a quick settlement: Do not accept a settlement offer without legal advice. Early offers are often far below what your case is worth.
- Discarding evidence: Keep all medical records, service records, employment records, and any documents related to your exposure.
- Posting on social media: Defense lawyers may use your social media posts to argue that your illness is less severe than claimed. Limit public posts about your health and activities.
AFFF and Veterans: Special Considerations
Veterans are among the most affected by AFFF exposure. Hundreds of military bases have PFAS-contaminated water, and many veterans used AFFF in training and operations. Important points for veterans:
- VA benefits: You may be eligible for VA disability benefits for PFAS-linked conditions, in addition to an AFFF lawsuit. The two are separate — VA benefits do not reduce your lawsuit recovery.
- Feres doctrine: The Feres doctrine generally bars active-duty service members from suing the government for injuries incident to service. However, AFFF lawsuits are filed against the manufacturers (3M, DuPont, etc.), not the government — so Feres does not block AFFF claims.
- Service records: Your DD-214 and service records are key evidence. Your lawyer can help you obtain them if you do not have copies.
- PACT Act: The Honoring Our PACT Act of 2022 expanded VA benefits for veterans exposed to toxic substances, including PFAS. Ask your lawyer or VA representative about PACT Act benefits.
Frequently Asked Questions
Do I need to prove exactly how much AFFF I was exposed to?
No. Your lawyer will use service records, employment records, water testing data, and expert testimony to establish that you were exposed to AFFF / PFAS. You do not need to quantify your exact exposure.
What if I was exposed years ago?
PFAS stays in the body for years, and health effects can appear decades after exposure. As long as you are within the statute of limitations (which typically starts at diagnosis or discovery), you can still file.
Can I file if I already receive VA benefits?
Yes. VA benefits and AFFF lawsuits are separate. Receiving VA disability compensation does not prevent you from filing an AFFF lawsuit against the manufacturers.
How long does an AFFF case take?
Most AFFF cases take 1–3 years from filing to settlement, depending on the MDL schedule, bellwether trials, and settlement negotiations. Your lawyer can give you a more specific timeline based on current MDL progress.
Will I have to go to court?
Probably not. The vast majority of AFFF cases settle before trial. You may need to provide a deposition, but most plaintiffs never appear in court.
What if the base or facility where I was exposed is closed?
It does not matter. Your claim is against the AFFF manufacturers, not the base or facility. Closed bases are still the subject of EPA cleanup and water testing, which provides evidence for your case.
The Bottom Line
AFFF lawsuits are about accountability. For decades, manufacturers sold firefighting foam containing PFAS — chemicals they knew were dangerous — without warning the firefighters, service members, and communities who were exposed. The result: thousands of people diagnosed with cancer, thyroid disease, and other serious conditions.
If you were exposed to AFFF and diagnosed with a qualifying condition, you may be entitled to significant compensation — for medical bills, lost income, pain and suffering, and more. The AFFF litigation is active in 2026, and new claims are being filed every month.
Do not wait. Contact an experienced AFFF lawyer for a free consultation. There is no upfront cost, and you pay nothing unless you win. Your health and your family's financial future are worth protecting.
