Active litigationUpdated FEB 19, 2026

AFFF firefighting foam containing per- and polyfluoroalkyl substances (PFAS) has been used since the 1960s at military bases, airports, and fire training facilities across the United States. These "forever chemicals" do not break down in the environment and have contaminated groundwater, soil, and drinking water supplies serving millions of Americans. The C8 Science Panel established "probable links" between PFAS exposure and six diseases including kidney cancer, testicular cancer, and thyroid disease. MDL 2873, consolidated before Judge Richard Gergel in the District of South Carolina, encompasses over 15,216 personal injury claims against manufacturers including 3M, DuPont, Chemours, Tyco Fire Products, and BASF. Water utility settlements exceeding $12.5 billion have been approved, and the personal injury track is advancing toward bellwether trials with Daubert motions and expert depositions underway.

Litigation Timeline

10 ENTRIES
  1. April 2024

    EPA Finalizes First-Ever PFAS Drinking Water Standardsregulatory

    The U.S. Environmental Protection Agency finalizes the first-ever enforceable National Primary Drinking Water Regulation for PFAS, setting maximum contaminant levels (MCLs) of 4 parts per trillion for PFOA and 4 parts per trillion for PFOS. Simultaneously, the EPA designates PFOA and PFOS as hazardous substances under CERCLA (Superfund law). These twin actions represent the most significant federal regulatory response to PFAS contamination and create new compliance obligations for water systems, cleanup authority for the EPA, and additional legal exposure for AFFF manufacturers.

  2. November 2023

    IARC Classifies PFOA as Group 1 Carcinogenregulatory

    The International Agency for Research on Cancer (IARC) publishes Monograph Volume 135, classifying PFOA as a Group 1 carcinogen — the highest classification, indicating sufficient evidence of carcinogenicity in humans. PFOS is classified as Group 2B (possibly carcinogenic). The Group 1 designation places PFOA alongside asbestos, benzene, and tobacco smoke, providing the strongest possible scientific endorsement of the link between PFOA exposure and cancer. This classification significantly strengthens causation arguments in the personal injury litigation.

    3M Announces $10.3 Billion Water Utility Settlementsettlement

    3M agrees to pay $10.3 billion over 13 years to resolve claims from more than 300 public water systems alleging PFAS contamination from AFFF and other 3M products. It is the largest PFAS settlement in history and one of the largest environmental settlements ever reached. The settlement covers water testing, treatment, and remediation costs but does not resolve the personal injury claims of firefighters, military personnel, and community residents, which continue through MDL 2873.

  4. 2018

    MDL 2873 Formed; Minnesota Settles with 3M for $850Mfiling

    The Judicial Panel on Multidistrict Litigation creates MDL 2873 in the District of South Carolina (Charleston) before Judge Richard Gergel to consolidate the growing number of AFFF/PFAS lawsuits. Separately, the State of Minnesota settles its environmental enforcement action against 3M for $850 million, resolving claims that 3M's PFAS manufacturing and disposal contaminated groundwater across the Twin Cities metropolitan area. The Minnesota settlement signals the scale of financial exposure facing AFFF manufacturers.

  5. 2012

    C8 Science Panel Determines "Probable Link" to Six Diseasesregulatory

    The C8 Science Panel — an independent epidemiological study created as part of the DuPont class action settlement — completes its analysis of health data from 69,000 residents in the Mid-Ohio Valley exposed to PFOA-contaminated drinking water. The panel determines a "probable link" between PFOA exposure and six diseases: kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, high cholesterol, and pregnancy-induced hypertension. These findings become the foundational causation science for all subsequent PFAS personal injury litigation.

  6. 2001

    Attorney Robert Bilott Files Suit Against DuPontfiling

    Attorney Robert Bilott of the law firm Taft Stettinius & Hollister files suit against DuPont on behalf of Wilbur Tennant, a West Virginia farmer whose cattle were dying from PFOA contamination. Bilott's investigation uncovers DuPont's decades-long concealment of PFOA toxicity data and leads to the class action settlement that creates the C8 Science Panel. Bilott's work is later depicted in the 2019 film "Dark Waters" and establishes the legal and scientific foundation for the current AFFF litigation.

  7. 2000

    3M Announces Voluntary PFOA/PFOS Production Haltregulatory

    3M announces the voluntary phase-out of PFOA and PFOS production after the EPA begins investigating the chemicals. The decision comes after decades of internal knowledge about PFAS toxicity. 3M continues to sell existing AFFF inventory and does not issue warnings to the millions of firefighters and military personnel who have been using PFAS-containing AFFF. The company's phase-out does not include cleanup of the contamination already caused by decades of AFFF use.

  8. 1970s

    3M Discovers PFAS in Worker Blood at 1,000x Normalverdict

    Internal 3M studies find that PFAS levels in the blood of production workers at the company's Cottage Grove, Minnesota facility are approximately 1,000 times higher than in the general population. Company toxicologists conclude that PFOA and PFOS "should be regarded as toxic" based on animal studies showing liver damage, reproductive harm, and tumor formation. Despite these findings, 3M conceals the data and continues manufacturing AFFF for another 24 years.

  9. 1960s

    US Navy and 3M Develop AFFFproduct-launch

    The United States Navy partners with 3M Company to develop aqueous film-forming foam (AFFF) as a fire suppressant for shipboard and airfield use. The Navy files patents for AFFF formulations in 1963. The foam's PFOS-based surfactants create a thin aqueous film on burning fuel surfaces that is uniquely effective at extinguishing petroleum fires. The Department of Defense mandates AFFF use at all military airfields, establishing the product as the standard across hundreds of installations.

  10. 1938

    PTFE Accidentally Discovered at DuPontproduct-launch

    Roy Plunkett, a chemist at DuPont, accidentally discovers polytetrafluoroethylene (PTFE) — the precursor to Teflon and the foundation of the PFAS chemical family. The discovery of the extraordinary stability and non-stick properties of the carbon-fluorine bond launches a new era in fluorochemistry that will eventually produce the PFAS compounds used in AFFF.
