If you served as a military firefighter, worked at a Pennsylvania airfield, or lived near a military installation and have since been diagnosed with cancer or a serious illness, PFAS chemicals from AFFF firefighting foam may be worth evaluating as a contributing factor. Aqueous Film-Forming Foam was used for decades at military bases and civilian airports to suppress fuel fires. It contains PFOS and PFOA - two PFAS compounds that federal health agencies have linked to elevated cancer risk.
Pennsylvania claimants are part of MDL 2873, In re: Aqueous Film-Forming Foams Products Liability Litigation, consolidated in the District of South Carolina. As of June 2026, that proceeding continues to advance through bellwether scheduling and active settlement discussions.
This page is not legal advice. Filing deadlines for AFFF claims vary by state and depend on your individual circumstances. Talk to a licensed attorney in Pennsylvania before making any decisions about your claim.

Pennsylvania's AFFF Filing Window
Pennsylvania's standard personal injury statute of limitations is two years from the date of injury (42 Pa. C.S. SS 5524). That general rule, however, rarely applies straightforwardly to AFFF-related illness claims. PFAS chemicals cause diseases - including several cancers - that typically carry latency periods of years or even decades after exposure. A Pennsylvania firefighter who trained with AFFF at Willow Grove Naval Air Station in the 1980s or 1990s may receive a kidney cancer diagnosis years later.
Pennsylvania courts recognize the discovery rule, which tolls the limitations period until the plaintiff knew - or reasonably should have known - of the injury and its potential connection to a defendant's conduct. For AFFF claimants, this typically means the two-year window may begin when:
- ·A physician confirms a qualifying diagnosis
- ·Medical records or test results connect the diagnosis to PFAS exposure
- ·The claimant learns of contamination records tied to a nearby military installation or airport
Federal tolling rules may also apply in limited circumstances to veterans with government-specific claims, though most civilian AFFF personal-injury cases proceed through MDL 2873 rather than the Federal Tort Claims Act.
Filing deadlines vary by state. The specific facts of your exposure, your diagnosis, and when you first made the connection all affect your window. Do not assume your deadline has passed - and do not assume it has not. Consult a licensed attorney in Pennsylvania who handles AFFF claims.
Who Qualifies for an AFFF Claim in Pennsylvania
MDL 2873 generally encompasses claimants who were directly exposed to PFAS through AFFF use and who subsequently developed a qualifying medical condition.
Exposure groups that appear in Pennsylvania AFFF cases:
- ·Military firefighters - including Air Force, Navy, Marine Corps, and Army Aviation members - who trained with or deployed AFFF at Pennsylvania installations (Willow Grove Naval Air Station, Tobyhanna Army Depot, 171st Air Refueling Wing at Pittsburgh International, and others)
- ·Pennsylvania National Guard firefighting personnel
- ·Civilian firefighters at military-adjacent airports or industrial fire-response facilities
- ·Airport firefighting personnel at Philadelphia International, Pittsburgh International, and regional airports
- ·Residents and former residents whose municipal or private well water was contaminated by PFAS runoff from nearby military installations
Qualifying conditions (based on current MDL 2873 science proceedings):
- ·Kidney cancer
- ·Testicular cancer
- ·Bladder cancer
- ·Prostate cancer
- ·Thyroid disease
- ·Non-Hodgkin's lymphoma
- ·Ulcerative colitis
This list is actively refined as expert proceedings develop. A licensed attorney can assess whether your specific diagnosis fits the current accepted cohort for MDL 2873.
Documenting Exposure and Your Qualifying Condition
Two evidentiary pillars support most AFFF claims: evidence of PFAS exposure and medical documentation of a qualifying condition. Attorneys typically work with environmental scientists and medical experts to connect these elements, but the underlying records start with you.
Exposure documentation:
- ·Military service records (DD-214, unit training logs) confirming firefighting duty at installations known to have stored or used AFFF
- ·Department of Defense environmental remediation records for affected Pennsylvania bases - available through the DoD Installation Restoration Program and PFAS site lists
- ·EPA PFAS contamination data for military sites near your former residence or workplace
- ·Employment records from civilian airports or industrial fire-response departments
- ·Municipal or private well water testing results showing elevated PFAS concentrations
Medical documentation:
- ·Pathology reports confirming your diagnosis
- ·Oncology or specialist records showing the diagnosis date and treatment history
- ·Primary care records documenting symptom history
Gathering military records through the National Personnel Records Center can take several months. Starting that process before formal litigation reduces delays. Many AFFF attorneys guide record retrieval during intake at no upfront cost to you.
How Pennsylvania AFFF Cases Move Through MDL 2873
AFFF cases filed by Pennsylvania claimants typically originate in one of the state's three federal judicial districts - the Eastern District (Philadelphia), Middle District (Harrisburg/Scranton), or Western District (Pittsburgh) - depending on where you reside or where the exposure occurred. The Judicial Panel on Multidistrict Litigation then transfers each case to MDL 2873 in the District of South Carolina under 28 U.S.C. SS 1407.
MDL 2873 is not a class action. It is a coordination mechanism that groups thousands of individual claims for pretrial discovery, expert witness proceedings, and bellwether trials. Each claimant retains a separate case and separate counsel. You are not automatically bound by outcomes in other plaintiffs' cases.
The MDL process has included:
- ·Plaintiff Fact Sheet (PFS) submissions documenting exposure and diagnosis history for each claimant
- ·General causation expert proceedings establishing the scientific link between PFAS and qualifying diseases
- ·Bellwether trial selections to test liability theories and damages ranges against representative defendants
If a global settlement is negotiated - as occurred with 3M on the municipal water-system track - individual plaintiffs receive separate offers and retain the independent right to accept or reject. No attorney can require you to settle.
What AFFF Settlement Ranges Have Looked Like
AFFF personal-injury litigation is at a different stage than the water-system settlements. 3M's resolution with municipal water providers, announced in 2023 at a reported $10.3 billion, covers municipal water systems - not individual cancer claimants. Those are separate tracks within MDL 2873 and related proceedings.
Personal-injury bellwether cases have been advancing through pretrial scheduling. Reported settlement values in individual PFAS/AFFF personal-injury cases have varied based on:
- ·The specific diagnosis and its severity or stage
- ·Duration and documented intensity of PFAS exposure
- ·The claimant's age at diagnosis and medical prognosis
- ·Defendant-specific liability factors and exposure pathways
No publicly available settlement formula applies to individual claims. Individual case reports have cited ranges that vary widely depending on the above factors. These are anecdotal data points from distinct cases with distinct facts - not projections for your case, and not guarantees of any outcome.
Any settlement offer you receive will come through your licensed attorney. Never sign a settlement or release document without fully understanding the terms.
