PFAS Lawsuit Update Today: Latest Litigation, Settlements, and Legal Developments

This PFAS lawsuit update today covers the most recent activity in the sprawling litigation over per and polyfluoroalkyl substances, commonly called forever chemicals. The past several weeks have brought a significant appellate court ruling, a major federal settlement, and continued movement inside the multidistrict litigation that houses thousands of individual claims. Below is a plain language breakdown of where things stand, organized by case type so readers can understand exactly which piece of the litigation applies to their situation.

PFAS Lawsuit Update Today: Latest Developments

Several developments define this PFAS lawsuit update today. On August 18, 2026, the U.S. Court of Appeals for the District of Columbia Circuit upheld the EPA’s 2024 rule designating PFOA and PFOS as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act, also known as CERCLA or Superfund. The unanimous three judge panel rejected industry challenges brought by the U.S. Chamber of Commerce and other trade groups in Chamber of Commerce of the United States of America v. EPA.

In parallel, the federal Aqueous Film-Forming Foam multidistrict litigation, pending before Judge Richard Gergel in the U.S. District Court for the District of South Carolina, continues to process an active docket. According to court tracking data, roughly 15,246 AFFF related lawsuits were pending in the MDL as of early August 2026, a number that has held relatively steady in recent months after growing for years.

On the settlement front, the EPA and the Department of Justice announced on June 24, 2026, a $450 million settlement with The Chemours Company resolving federal claims tied to PFAS releases at facilities in West Virginia, North Carolina, and New Jersey. This PFAS settlement update is separate from the AFFF personal injury litigation and does not resolve individual injury claims.

Each of these threads represents a different track of PFAS litigation, and readers should not assume that a development in one case applies automatically to another.

What Is the PFAS Litigation About?

PFAS refers to a large family of manmade chemicals that have been used since the 1940s in products such as nonstick cookware, water repellent fabrics, food packaging, and firefighting foam. These chemicals resist breaking down in the environment, which has led to their nickname, forever chemicals, and they have been detected in soil, groundwater, and public drinking water systems across the country.

The plaintiffs allege that chemical manufacturers, including 3M, DuPont, Chemours, and others, knew or should have known about the health and environmental risks associated with PFAS and failed to adequately warn the public, water utilities, or regulators. Defendants have generally denied liability in litigation that remains ongoing, and allegations in complaints are not findings of fact or court rulings.

Broadly, PFAS lawsuit filings fall into several distinct categories:

• Public water system contamination lawsuits, brought by municipalities and water authorities seeking to recover cleanup and treatment costs
• AFFF lawsuit claims brought by firefighters, military personnel, and airport workers alleging personal injury from occupational exposure to firefighting foam
• Individual PFAS exposure lawsuit and PFAS personal injury lawsuit claims tied to specific diagnoses
• Regulatory and enforcement actions brought by the EPA and DOJ against manufacturers
• State attorney general lawsuits seeking natural resource damages and remediation funding

Understanding which category a given news item falls into is essential, since a public water settlement does not automatically create eligibility for a personal injury claim, and vice versa.

Major PFAS Lawsuits Currently Moving Forward

The centerpiece of federal PFAS litigation is In Re: Aqueous Film-Forming Foams Products Liability Litigation, MDL No. 2873, consolidated in the District of South Carolina. This PFAS multidistrict litigation includes claims from firefighters, military members, and residents near installations where AFFF was used, alongside water provider claims. According to court records, the MDL judge appointed a Special Master, the Honorable Margaret B. Seymour (Ret.), to review requests to dismiss thousands of claims for insufficient documentation, an administrative process aimed at clarifying which cases have adequate evidentiary support to proceed.

Separately, state attorneys general and municipal water systems, including Kansas City, have pursued their own PFAS contamination lawsuit actions seeking compensation for testing, treatment infrastructure, and long-term monitoring costs tied to contaminated water supplies. These public entity cases are distinct from personal injury claims and are typically resolved through negotiated settlements funding remediation rather than individual payouts.

State level enforcement has also continued. Chemours agreed to pay a combined civil penalty and mitigation package to West Virginia, North Carolina, and New Jersey, while BASF Corporation separately agreed to a settlement with the State of New Hampshire directed toward that state’s drinking water and groundwater trust fund. These state settlements exist alongside, not instead of, the federal MDL process.

Latest PFAS Settlement Developments

This PFAS lawsuit update today would not be complete without a closer look at settlement activity. The most significant recent PFAS settlement update involves Chemours. On June 24, 2026, the EPA, DOJ, and West Virginia Department of Environmental Protection announced what officials described as the first comprehensive federal settlement with a major PFAS manufacturer. According to the settlement terms, Chemours will spend more than 337 million dollars on injunctive relief, including an estimated 280 million dollars to provide alternative drinking water and 60 million dollars to bring its West Virginia facility into compliance. The agreement also requires a multi year, government supervised 90 million dollar PFAS mitigation program and includes a 22.5 million dollar civil penalty. The proposed consent decree was filed in the U.S. District Court for the Southern District of West Virginia, and public comments were accepted through late July 2026.

It is worth noting that this settlement resolves federal Clean Water Act, Resource Conservation and Recovery Act, and Toxic Substances Control Act claims against Chemours. It does not resolve the AFFF personal injury claims pending in the MDL, and it does not establish a compensation fund for individuals.

As of late August 2026, no new global settlement covering the personal injury track of the AFFF MDL has been announced. Earlier public water system settlements from companies including 3M and DuPont, reached in prior years, remain in various stages of implementation and are separate from the personal injury docket. Any reader evaluating a potential PFAS compensation opportunity should confirm which settlement, if any, actually applies to their specific circumstances rather than assuming broad eligibility.

AFFF and PFAS Personal Injury Litigation

The AFFF lawsuit track within the broader PFAS multidistrict litigation is the largest source of individual claims. Plaintiffs, many of them firefighters, military veterans, and airport personnel, allege that repeated occupational exposure to aqueous film-forming foam contributed to diagnoses including kidney cancer, testicular cancer, thyroid disease, and ulcerative colitis. Firefighters are considered a high exposure population, and some published research has found elevated rates of certain cancers within that occupation, though establishing individual causation in a specific case remains a matter for expert testimony and the courts.

According to court filings, the MDL previously scheduled bellwether trials, which are early test cases used to gauge how juries might respond to the evidence, but the court vacated an earlier trial date in 2025 after a surge of new filings required additional time to verify medical and exposure documentation. A new bellwether trial date had not been set as of this update. Science Day presentations held earlier examined the purported links between PFAS exposure and several diseases, a process courts often use to help manage complex scientific evidence ahead of trial.

Because so many claims remain in early stages, plaintiffs and prospective claimants should understand that a PFAS exposure lawsuit requires documented exposure, a qualifying diagnosis, and supporting medical evidence. Winning a settlement is not guaranteed, and PFAS lawsuit settlement amounts, where they eventually exist, will vary based on case specific factors including injury severity, exposure history, and jurisdiction. No individual payout figures have been confirmed for the personal injury track as of this publication.

Recent Court Decisions and Regulatory Actions

The most consequential recent regulatory development is the D.C. Circuit’s August 18, 2026 decision upholding the EPA’s designation of PFOA and PFOS as hazardous substances under CERCLA. The panel, comprised of Judges Patricia Millett, Gregory Katsas, and Neomi Rao, rejected arguments from industry petitioners that the EPA exceeded its statutory authority and failed to adequately justify the rule through cost-benefit analysis. The court found that the relevant statutory language required only a showing that a substance may present a substantial danger, not proof that harm will definitely occur.

This ruling is significant because it preserves the EPA’s ability to use CERCLA’s cost recovery and cleanup framework against parties responsible for PFOA and PFOS contamination, potentially exposing manufacturers, industrial users, and in some cases waste handlers to long term cleanup liability. Legal commentators have noted the decision could also inform pending challenges to EPA’s separate Safe Drinking Water Act maximum contaminant levels for other PFAS compounds. Petitioners have the option to seek rehearing en banc or petition the U.S. Supreme Court for review, with a certiorari deadline falling in the fall of 2026. Regulated parties should continue treating the designation as legally operative unless a court issues a stay.

Beyond the CERCLA ruling, EPA data reported in 2025 indicated that millions of additional Americans have drinking water systems affected by PFAS contamination, a figure that has continued to inform both regulatory priorities and the pace of new municipal water contamination lawsuit filings.

Who May Be Affected by PFAS Litigation?

This section of the PFAS lawsuit update today outlines who may have a connection to ongoing PFAS litigation, though eligibility for any specific claim or settlement always depends on the particular facts and the terms of that case:

• Firefighters and former firefighters, including municipal, military, and airport crash rescue personnel who used AFFF
• Military service members and veterans stationed at bases where firefighting foam was used in training or emergency response
• Residents who obtained drinking water from a public water system with documented PFAS contamination
• Individuals diagnosed with certain cancers or conditions who also have documented PFAS exposure history
• Municipalities, water utilities, and public agencies responsible for water treatment costs

Importantly, exposure to PFAS alone does not automatically qualify a person for compensation. A viable PFAS personal injury lawsuit typically requires documented exposure, a qualifying medical diagnosis supported by evidence, and a claim filed within the applicable statute of limitations, which varies by state. Some states apply a discovery rule that begins the clock when a person discovers, or reasonably should have discovered, an injury connected to PFAS exposure, rather than at the time of exposure itself. Anyone considering a PFAS claims filing should consult a licensed attorney to evaluate the specific deadlines and evidentiary requirements that apply to their state and situation.

What Could Happen Next?

Looking ahead, this PFAS lawsuit update today points to several developments worth watching in the coming months. Petitioners in the CERCLA case have a window to seek rehearing or Supreme Court review, and how that plays out will shape the scope of future EPA enforcement. Within the AFFF MDL, the ongoing review of claims for potential dismissal, along with any new bellwether trial scheduling, will likely influence the pace of broader settlement talks. Some legal analysts have suggested that a global resolution of the personal injury track could take further time to materialize, though no such settlement has been finalized, and any timeline remains speculative rather than confirmed.

Additional state level enforcement actions and municipal water contamination lawsuit filings are also likely, following the pattern set by the Chemours and BASF settlements. Readers should treat any reported timeline for a nationwide personal injury settlement as an estimate, not a certainty, since multidistrict litigation of this scale can take years to resolve fully.
