Last updated: June 2026. California has some of the highest documented PFAS contamination levels in the United States, concentrated around military bases, industrial sites, and municipal water systems that used AFFF firefighting foam. Residents who developed qualifying cancers or conditions after PFAS exposure in drinking water or other sources may have claims under the federal MDL 2873 consolidated proceedings in the District of South Carolina.
This page covers California's filing window, who qualifies, how exposure is documented, and what the current settlement framework looks like. Filing deadlines vary by state and case type. This is not legal advice. Talk to a licensed attorney in your state to evaluate your specific situation.
California's Filing Window for PFAS Claims
PFAS claims in California are subject to state statute of limitations rules that vary depending on the type of claim and when the claimant knew or should have known about the link between exposure and injury.
General rule: California Code of Civil Procedure section 335.1 provides a two-year window for personal injury claims. The clock generally runs from the date of injury or discovery, whichever is later. Statute of limitations periods vary by state and claim type.
Discovery rule: California follows the discovery rule, which tolls the statute of limitations until the plaintiff knew or reasonably should have known of the injury and its cause. For PFAS-related cancers, courts have applied the discovery rule where the link between PFAS exposure and specific cancers was not publicly established until recent years.
Federal MDL timeline: Most PFAS personal injury cases are now centralized in MDL 2873 (In re: AFFF Products Liability Litigation, D.S.C., Judge Richard Gergel). Individual California cases that meet the MDL criteria are transferred to the District of South Carolina for coordinated pre-trial proceedings. The MDL does not eliminate California's individual filing deadlines - claimants still need to act within the applicable state window before or alongside filing in the MDL.
Tolling considerations: Class action tolling, active military service, and minority tolling for claimants who were minors at the time of exposure may extend the window. Tolling rules vary by state and are fact-specific.
Do not rely on this page as a deadline calculation for your case. Filing deadlines vary by state and are highly fact-specific. Talk to a licensed attorney in your state as soon as possible.
Who Qualifies for a PFAS Lawsuit in California
Qualifying PFAS claimants in California generally share three characteristics:
1. Documented exposure source. The most common exposure sources in California-based claims include:
- ·Contaminated municipal drinking water from systems near military installations (Camp Pendleton, Vandenberg Space Force Base, Edwards Air Force Base, March Air Reserve Base, NAS Lemoore, and others)
- ·Firefighting foam (AFFF) exposure for military personnel, civilian airport employees, or first responders
- ·Industrial PFAS discharge near manufacturing sites
2. Qualifying diagnosis. The PFAS MDL and most PFAS litigation focuses on conditions with established epidemiological links to PFAS exposure. Conditions frequently cited in PFAS litigation include kidney cancer, testicular cancer, thyroid disease, ulcerative colitis, and certain immune disorders. The scientific record is still developing. Qualifying conditions in your specific case depend on your diagnosis and the litigation's current scope.
3. Sufficient exposure duration. Most plaintiffs' experts require documented exposure for a meaningful period before symptom onset. There is no fixed minimum - this is a case-specific analysis.
There is no universal checklist that determines whether you have a qualifying claim. Talk to a licensed attorney who handles PFAS litigation to evaluate your exposure history and diagnosis.
How Exposure and Qualifying Conditions Are Documented
Building a PFAS claim requires documentary evidence of both the exposure source and the qualifying condition. Here is what attorneys typically gather in California PFAS cases:
Exposure documentation:
- ·EPA and state water utility PFAS testing records (many California utilities are required to test and disclose)
- ·EPA's PFAS Contaminated Sites Tracker, which maps confirmed contamination near military bases
- ·Employment records for military or airport personnel showing assignment to AFFF-affected locations
- ·Utility bills and address history showing residence near a contaminated water source
- ·Water district notices about PFAS exceedances (California utilities issued many after EPA's 2016 Health Advisories)
Medical documentation:
- ·Pathology reports, imaging, and treating physician records confirming diagnosis
- ·Dates of diagnosis relative to the exposure period
- ·Medical records from the period before diagnosis showing relevant symptoms or labs
Blood serum PFAS testing is available through commercial labs and may help establish exposure level, though its admissibility and significance varies by case. Talk to an attorney about whether serum testing makes sense for your situation.
California-Specific Procedural Notes
California PFAS personal injury claims for AFFF exposure are typically filed in federal court. Most are then transferred to MDL 2873, centralized in the District of South Carolina under Judge Richard Gergel. As of June 2026, MDL 2873 continues with bellwether trials and ongoing settlement negotiations.
State vs. federal track: California state-court PFAS claims exist but are less common for personal injury cases linked to AFFF or military contamination. Water utility contamination claims may take a different procedural path - some California municipalities and water districts have filed or joined separate litigation against PFAS manufacturers.
3M settlement: In June 2023, 3M Company reached a settlement agreement with U.S. public water systems for amounts reported in public sources as ranging from $10.3 billion to $12.5 billion over multiple years. This settlement addressed water utility claims, not individual personal injury claims. Individual claimants are not parties to the 3M-water-utility settlement.
DuPont and Chemours: Separate settlement discussions and proceedings involve DuPont, Chemours, and Corteva. The structure and timing of any individual personal injury resolution from these proceedings is not finalized as of this update.
Current MDL status is subject to change. Check with a licensed attorney in your state for the most current procedural status.
What the PFAS Settlement Framework Looks Like
Reported settlement ranges from public sources should be understood as estimates tied to specific cases and conditions - not guarantees or predictions for any individual claim.
Public reporting on PFAS personal injury verdicts and settlements has shown wide variation based on diagnosis severity, exposure duration, age at diagnosis, and jurisdiction. Individual PFAS claim values in published reports have ranged from tens of thousands of dollars to multi-million-dollar figures in cases involving severe cancers diagnosed at young ages. These figures represent specific outcomes in specific cases and should not be interpreted as a prediction for any other claim.
No attorney can guarantee any specific outcome in a PFAS case. Settlement amounts depend on individual facts, the strength of available evidence, the current state of MDL negotiations, and factors specific to your case. This is not legal advice. Talk to a licensed attorney to evaluate your specific situation.
