If you or someone you love is facing a diagnosis like cancer, thyroid disease, or another serious illness, and you have started to wonder whether contaminated water or a product played a role, please know two things. What you are feeling, the worry, the anger, the search for answers, is understandable. And a serious illness that may trace back to contamination is not a personal failing. By no means is it something you brought on yourself.

You may also have seen headlines about billion-dollar PFAS settlements and felt unsure whether any of it applies to your family. The numbers are large, and they are hard to connect to a single person sitting in a doctor’s office. This article is here to make sense of that.

This article explains, in plain language, what PFAS are, what the science says about them, what the major settlements actually cover, and how individual health claims work. Wherever you are in this process, you can take it one step at a time.

What PFAS Are and Why They Are Called Forever Chemicals

PFAS, short for per- and polyfluoroalkyl substances, are a large family of human-made chemicals that have been used since the mid-twentieth century to resist heat, grease, stains, and water. You will find them, or their history, in nonstick cookware, water-repellent fabrics, grease-resistant food packaging, certain cosmetics, and a firefighting foam called aqueous film-forming foam, or AFFF. They are nicknamed forever chemicals because their chemical bonds are so strong that they break down very slowly, lingering in the environment and in the human body for years.

They are also widespread. A 2023 study by the U.S. Geological Survey (USGS) estimated that at least 45 percent of the nation’s tap water may contain one or more types of PFAS.

The federal government has begun to respond. In 2024, the Environmental Protection Agency (EPA) set the first national drinking water limits for several PFAS, including a limit of 4 parts per trillion each for two of the most studied, PFOA and PFOS, along with a health-based goal of zero for those two, reflecting the view that no level of exposure is known to be free of risk. In 2026, the EPA proposed keeping those two limits while allowing water systems to request an extension, to 2031, to come into compliance, and proposed rescinding the limits it had set for four other PFAS. Those proposals are still moving through the public process, and the 2024 rule remains in place in the meantime.

The Health Conditions Linked to PFAS Exposure

Much of what is known about PFAS and human health comes from a single community. After PFOA, also called C8, contaminated drinking water near a chemical plant in West Virginia, an independent group of scientists known as the C8 Science Panel spent years studying tens of thousands of exposed residents. In 2012, the panel reported a “probable link” between PFOA and six conditions: kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, pregnancy-induced hypertension including preeclampsia, and high cholesterol.

It helps to understand what “probable link” means. The panel defined it as a finding that, for that highly exposed community, a connection was more likely than not. It is a statement about association, not a guarantee of cause in any one person, and the science has continued to develop in the years since. Researchers have also studied the possible effects of PFAS on the immune system.

In the firefighting foam litigation, the conditions with the strongest scientific support, and the ones courts have focused on first, are kidney cancer and testicular cancer. Thyroid disease, certain other cancers, and ulcerative colitis are also among the recognized conditions. Whether any individual’s illness is connected to PFAS depends on the facts and on medical evidence.

How the PFAS Litigation Began

The story of PFAS litigation often returns to that West Virginia plant. DuPont used PFOA at its Washington Works facility near Parkersburg beginning in the 1950s, and the chemical reached the drinking water of surrounding communities. A class action known as Leach led to a settlement in the mid-2000s that funded the independent science panel and a medical monitoring program for residents.

Plaintiffs in PFAS cases have alleged, and court records and investigations have documented, that manufacturers studied the risks of these chemicals for many years. The companies have denied wrongdoing. What is not in dispute is that the industry has changed course. 3M, a major manufacturer, voluntarily phased out its production of PFOA and PFOS beginning in 2000, and in 2022 announced it would exit all PFAS manufacturing by the end of 2025, a transition the company has since completed.

The Major PFAS Settlements and What They Do Not Cover

This is the part that causes the most confusion, so it is worth stating clearly.

In 2023, 3M agreed to pay at least $10.3 billion, and potentially up to $12.5 billion over 13 years, to settle claims brought by public water systems. The same month, DuPont, Chemours, and Corteva agreed to a $1.185 billion settlement, also with public water systems.

Here is the key point. Those settlements compensate water utilities for testing and cleaning up drinking water. They do not pay individuals for cancer or other health injuries. If you have a PFAS-related illness, none of that money is set aside for you. Personal injury claims are a separate matter.

Individuals can and do recover in their own cases, but through a different path. For example, in 2017, DuPont and Chemours agreed to pay $670.7 million to resolve about 3,550 personal injury lawsuits brought by residents of Ohio and West Virginia in the C8 cases. And in one of those cases, an Ohio jury awarded a man who developed testicular cancer $40 million, an award the Sixth Circuit Court of Appeals upheld in 2022. Results like these are not typical or promised, and outcomes vary widely from case to case, but they show that individual claims are real and can carry significant weight.

The Ongoing Individual Injury Litigation

Today, most individual PFAS injury claims tied to firefighting foam are gathered together in a single proceeding called multidistrict litigation, or an MDL. The firefighting foam MDL (formally MDL No. 2873) is overseen by Judge Richard M. Gergel in the United States District Court for the District of South Carolina.

As of mid-2026, roughly 15,000 or more individual injury cases were pending there. A first test trial, known as a bellwether and focused on a kidney cancer claim, had been scheduled for October 2025, but the court set it aside after a large wave of new filings required time to review documentation, and a new date had not yet been set. No nationwide settlement of the individual injury cases had been reached. This is active and evolving litigation, and nothing here predicts how it will turn out.

Who May Have a PFAS Injury Claim

Every situation is different, but in general, an individual claim tends to involve three things: documented exposure, such as work as a career or volunteer firefighter or a military service member who used or trained with AFFF, employment at an airport or certain industrial sites, or drinking water near a military base, airport, fire-training site, or manufacturing facility; a qualifying diagnosis, such as kidney cancer or testicular cancer, among the conditions the litigation recognizes; and a medical connection between the exposure and the illness, which attorneys and medical experts help to establish.

You do not need to have all of this figured out, or proven, before you ask a question. Eligibility and deadlines also vary from state to state and depend on the specific facts.

Frequently Asked Questions Regarding PFAS Injury Claims

Q: What health conditions may qualify for a PFAS claim?
A: The conditions with the strongest support in the current litigation are kidney cancer and testicular cancer, with thyroid disease, certain other cancers, and ulcerative colitis also recognized. Whether a particular illness qualifies depends on the facts and the medical evidence.

Q: How would I know whether I was exposed?
A: Common sources include the use of firefighting foam, living near a military base, airport, fire-training site, or industrial facility, and drinking water from a supply known to contain PFAS. Public water systems publish annual water quality reports, and these may note PFAS testing results.

Q: Do the 3M and DuPont settlements pay me directly?
A: No. Those large settlements are with public water systems, and they fund testing and treatment of drinking water. They do not compensate individuals. A personal injury claim is a separate matter.

Q: Do I have to prove which company’s PFAS harmed me?
A: Sourcing and causation are complicated questions, and they are addressed through the legal process with the help of experts. This is not something you are expected to sort out on your own before reaching out.

Q: Is it too late to file?
A: Maybe not. Time limits vary by state and are often measured from the date of diagnosis, or from when a person reasonably connected an illness to PFAS, rather than from the exposure itself. Because these deadlines can be easy to miss, it is wise to ask early.

Q: What can an individual claim seek?
A: Depending on the facts, a claim may seek compensation for medical costs, lost income, pain and suffering, and in some cases more. No outcome or amount can be promised.
