PFAS Lawsuits: How the U.S. Is Fighting Forever Chemicals

Last updated: October 2026

PFAS lawsuits are how Americans are fighting forever chemicals in court. Water utilities, states, cities, property owners and people who became sick have all sued the companies that made PFAS. The biggest results so far are billions of dollars in settlements for public water systems. Personal injury claims, especially from firefighting foam, are still waiting for resolution. Below, you will also learn how PFAS lawsuits differ by claim type, which records can help and what steps may lower your exposure at home.

This guide gives a plain-language overview of the national fight over PFAS: who is suing, what they want, what has been won so far, and where an individual may fit.

What are forever chemicals, and why are they in court?

PFAS (per- and polyfluoroalkyl substances) are thousands of man-made chemicals used since the 1940s. They resist heat, grease, water and stains. They show up in firefighting foam, nonstick coatings, water-resistant clothing, food packaging and industrial processes.

They are called “forever chemicals” because they break down very slowly. They can build up in water, soil and people’s bodies.

Health concerns are a major driver of lawsuits:

• The CDC’s ATSDR links some PFAS to higher cholesterol, lower vaccine response, liver enzyme changes, pregnancy-related high blood pressure, small decreases in birth weight, and kidney and testicular cancer (PFOA).
• In late 2023, the WHO’s cancer agency, IARC, classified PFOA as “carcinogenic to humans” and PFOS as “possibly carcinogenic to humans.”

Who is fighting forever chemicals in court

PFAS lawsuits across the U.S. fall into a few main groups.

Public water systems

Cities and water utilities sued PFAS makers to pay for testing and treatment. These are the cases that have produced the largest settlements so far.

States

Many state attorneys general have sued PFAS manufacturers over damage to natural resources, such as groundwater, rivers and wildlife. 3M’s 2026 financial filings, for example, refer to a settlement with New Jersey.

Individuals with health problems

People who developed cancer or other illnesses after heavy exposure have filed personal injury lawsuits. Most involve firefighting foam, drinking water near a plant or base, or workplace exposure.

Property owners and consumers

Some landowners claim PFAS lowered the value of their land or wells. Consumers have filed class actions over products marketed as safe that allegedly contained PFAS.

The largest front: the AFFF multidistrict litigation

Many PFAS lawsuits across the country have been combined in one federal court. The firefighting foam case, MDL 2873, is in the District of South Carolina before Judge Richard M. Gergel.

As of September 1, 2026, the Judicial Panel on Multidistrict Litigation reported 15,264 pending actions in MDL 2873. It is one of the largest MDLs in the country.

The MDL is limited to foam. In December 2025, the JPML said it “remains an AFFF MDL, not a PFAS MDL” and kept firefighter turnout gear cases out. Those gear cases now have their own federal MDL in Minnesota.

What PFAS lawsuits have won so far

The biggest wins have come for public water systems:

• 3M: up to $10.3 billion in present value over 13 years, with total payments that could reach about $12.5 billion. The court gave final approval on March 29, 2024, according to 3M.
• Chemours, DuPont and Corteva: $1.185 billion, announced June 2, 2023, according to DuPont.
• Tyco Fire Products: $750 million, and BASF: $316.5 million, as reported by Reuters.

These deals pay to clean up drinking water. They do not compensate individuals for illness.

For people with cancer, the fight continues. As of fall 2026, no global personal injury settlement had been announced in the AFFF MDL. The first personal injury bellwether trial, expected in October 2025, was postponed, and no new public trial date had been set.

How federal rules shape the fight

Regulation and litigation go hand in hand. Rules can set clear limits that lawsuits point to, and lawsuits can pressure companies to change.

Drinking water limits

In April 2024, EPA set the first national drinking water limits for six PFAS. PFOA and PFOS were each capped at 4 parts per trillion.

On May 18, 2026, EPA proposed to:

• Keep the PFOA and PFOS limits but allow some water systems until 2031, instead of 2029, to comply
• Rescind the limits for PFHxS, PFNA, GenX (HFPO-DA) and the Hazard Index mixture

A public hearing was held on July 7, 2026, and comments closed on July 20, 2026, according to a Jones Day summary and EPA materials. Final rules had not been issued as of this update.

Why this matters for lawsuits

Changes to drinking water rules do not decide who wins a lawsuit. But they affect how much cleanup water systems must do, and they are often cited in arguments about PFAS risk.

A short timeline of the fight

Here are some key moments in recent PFAS litigation and regulation:

• Late 2018 to early 2019: Federal firefighting foam cases are combined into MDL 2873 in South Carolina.
• June 2023: Chemours, DuPont and Corteva announce a $1.185 billion water system settlement.
• Late 2023: IARC classifies PFOA as carcinogenic to humans.
• March 2024: The court approves 3M’s water system settlement.
• April 2024: EPA sets national drinking water limits for six PFAS.
• 2025: The first AFFF personal injury bellwether trial is postponed, and the JPML keeps turnout gear cases out of the foam MDL.
• May 2026: EPA proposes to extend PFOA and PFOS compliance and drop limits for four other PFAS measures.
• September 2026: The AFFF MDL reports more than 15,000 pending actions.

Where an individual fits in the fight

If you are worried about PFAS, it helps to know which kind of claim, if any, may fit your situation. A participating law firm may review:

• Your exposure: foam use, a job at a plant, or living near a contaminated site or base
• Your diagnosis: such as kidney, testicular, thyroid or liver cancer, or ulcerative colitis
• Your records: medical records, work history and where you lived and for how long
• Your timing: deadlines vary by state and claim type

If your water utility has reported high PFAS levels, that alone may not create a personal injury claim. But combined with a serious diagnosis, it may be worth a closer look.

How to Lower Your PFAS Exposure While PFAS Lawsuits Continue

PFAS lawsuits can take years, and new drinking water rules are still being worked out. In the meantime, many families want to know what they can do at home. These steps cannot undo past exposure, but they may help lower it going forward.

Learn what is in your water

• Read your water utility’s annual water quality report, sometimes called a Consumer Confidence Report.
• Call your utility and ask whether it has tested for PFAS and what the results were.
• If you use a private well, contact your state or local health department about testing. Private wells are not covered by the same federal testing rules as public systems.

Consider a certified home filter

The EPA has guidance on filters certified to reduce PFAS. It says granular activated carbon, ion exchange and reverse osmosis systems used at the tap can greatly reduce PFAS levels. The EPA points to two certifications to look for:

• NSF/ANSI 53, for filters that reduce PFAS
• NSF/ANSI 58, for reverse osmosis systems

The EPA also gives two cautions. Filters only work if you replace parts on the maker’s schedule. And current certifications do not yet show that a filter removes PFAS all the way down to the EPA’s drinking water limits.

Other everyday steps

• Use filtered water for drinking, cooking and baby formula if your water has high PFAS levels.
• Follow local fish advisories if you fish in lakes or rivers near known contamination.
• If you are a firefighter, ask your department about its current foam and gear policies.

What Different PFAS Lawsuits Must Show

Not all PFAS lawsuits are alike. Each type of case asks a court to decide different questions, and the proof needed for one can look very different from another.

Personal injury cases

A person who sues over an illness usually must show:

• Exposure: proof of contact with PFAS, such as years of foam use or drinking contaminated water
• Diagnosis: a medical record of a condition linked to PFAS in the case
• Causation: evidence that the exposure more likely than not contributed to the illness
• Timing: that the claim was filed within the deadline, which varies by state and claim type

Causation is often the hardest part. Courts decide which scientific evidence may be heard, and those rulings can affect large groups of cases at once.

Water system cases

Public water systems generally focus on contamination levels and the cost of testing and treatment. These are the cases that produced the big settlements described above.

Property and consumer cases

Property owners usually need test results showing contamination and proof of lost value or cleanup costs. Consumer class actions often focus on how products were labeled and marketed. These PFAS lawsuits rarely require proof of illness.

Why the type of case matters to you

Knowing which kind of case fits your situation helps you focus on the right records. Someone with kidney cancer and years of foam use needs medical and work records. A homeowner with a contaminated well needs test results and property records. Some people may fit more than one category, such as a firefighter who also lived near a contaminated base. A participating law firm can sort out which claims, if any, may apply and how they would be handled together.

Records That Can Help in PFAS Lawsuits

If you think you may have a claim, gathering records early can make a review faster. You do not need everything before you talk to a law firm.

If you were a firefighter

• Names of the departments where you served, with dates
• Training records, especially foam training or live-fire drills
• Notes on how often you used foam and where
• Union, pension or personnel records

If you served in the military

• Your DD-214 or other service records
• The bases where you lived or worked, with dates
• Your job duties, especially any work with firefighting, aircraft or fuel

If you lived near a contaminated site

• Past addresses and the years you lived at each one
• Water bills or notices from your utility
• Any test results for your tap water or well
• Letters from health or environmental agencies about PFAS in your area

Medical records

• Pathology reports and diagnosis records
• Treatment records, such as surgery or chemotherapy
• Bills and insurance statements
• A list of your doctors and hospitals

Keep copies of everything in one folder. If records are missing, write down what you remember, including names of coworkers or neighbors who may recall the same events. A clear timeline of where you lived, where you worked and when you were diagnosed can help a firm judge whether PFAS lawsuits may fit your situation.

What to Know About PFAS Blood Testing

Some people wonder whether a blood test will prove they have a claim. The answer is more complicated.

What a blood test can and cannot tell you

The CDC’s Agency for Toxic Substances and Disease Registry says in its guidance for clinicians that PFAS blood test results do not provide information for treatment and do not predict future health problems. ATSDR has not set health-based screening levels for PFAS in blood.

A test can show that PFAS are in your body. ATSDR notes that PFAS enter the blood of people worldwide, so a result alone usually does not show where the exposure came from.

Talking with your doctor

If you are worried, talk with your doctor about your exposure history. Your doctor can decide whether testing makes sense for you and what follow-up care may help. A law firm reviewing PFAS lawsuits will usually focus more on your exposure history and diagnosis than on a single blood test.

Questions to Ask a Law Firm About PFAS Lawsuits

A first conversation can help you understand whether any of the PFAS lawsuits now in court may fit your situation. These questions can guide that talk.

About your claim

• Does my diagnosis match the conditions being pursued in current PFAS lawsuits?
• Would my case be part of the AFFF MDL, the turnout gear MDL or a state court case?
• What proof of exposure do you need from me?
• Which deadline applies to me, and when does it run out?

About the process

• What happens if a personal injury settlement is announced?
• How long do cases like mine usually take?
• Will I need to give a sworn statement or see a doctor for the case?
• How will you keep me updated?

About costs

• How are fees and case costs handled?
• Can I see the fee agreement in writing before I sign?

A firm should answer clearly and without pressure. It is fine to take time to think, and to ask follow-up questions later.

Common Mistakes to Avoid

People exploring PFAS lawsuits often make a few avoidable mistakes:

• Assuming a water settlement covers you. The large water system deals pay utilities, not individuals.
• Waiting for news before acting. Filing deadlines vary by state and claim type and may keep running.
• Throwing out old records. Training logs, pay stubs and old water notices can help show exposure.
• Relying on a blood test alone. Exposure history and diagnosis matter more in most PFAS lawsuits.
• Trusting payout promises. No global personal injury settlement had been announced as of fall 2026.
• Signing with more than one firm. This can cause delays and confusion.

If a family member died from an illness you believe was linked to PFAS, ask a firm whether a wrongful death claim may be possible. Rules differ by state.

A Short Glossary for PFAS Lawsuits

News about PFAS lawsuits is full of acronyms. Here are some of the most common.

• PFAS: Per- and polyfluoroalkyl substances, a large group of man-made chemicals.
• PFOA and PFOS: Two of the most studied PFAS, now limited in drinking water by EPA.
• AFFF: Aqueous film-forming foam, a firefighting foam that has contained PFAS.
• MDL: Multidistrict litigation, a federal process that groups similar cases before one judge.
• Bellwether trial: An early test trial that helps show how similar cases may play out.
• MCL: Maximum contaminant level, the legal limit for a chemical in public drinking water.
• Parts per trillion (ppt): A unit used for very small amounts of PFAS in water.
• Consumer Confidence Report: The yearly water quality report from your utility.
• Turnout gear: Protective clothing worn by firefighters, now the subject of its own MDL.
• Statute of limitations: The deadline to file a lawsuit. It varies by state and claim type.

Knowing these terms can help you follow updates on PFAS lawsuits and ask a law firm clear questions.
