Who can file now?
Camp Lejeune claims require at least 30 days of exposure between August 1953 and December 1987 plus a later covered illness. ATSDR links Hadnot Point water to VOC contamination involving TCE, PCE, benzene and vinyl chloride, according to the agency factsheet.

- Have a diagnosis that matches the litigation's injury definition
- Can document product, place, dates, and medical care
- Still fall within the state deadline or tolling rule
How is causation proved?
Medical records carry the claim. Courts look for diagnosis date, treatment history, pathology or motility testing, and a timeline that connects exposure to illness. Regulatory findings help frame exposure but do not replace personal proof.
EPA set enforceable drinking-water limits of 4.0 parts per trillion each for PFOA and PFOS in 2024. FDA added a severe-gastroparesis warning for GLP-1 drugs in October 2025. Strong files pair workplace or prescription records with dose, duration, and consistent symptoms. Gaps in care, another likely cause, or missing exposure proof weaken causation.
What deadlines control your claim?
State discovery rules and court orders set different cutoffs, so filing windows are not uniform. AFFF closed its new-filing window on September 5, 2025. GLP-1 litigation faces expert-causation hearings in September 2026. Camp Lejeune has court-driven pressure toward resolution.

Federal judges ordered a global settlement plan by October 30, 2026, with first bench trials set for November 9 and 16. That schedule matters most for aging veterans and families awaiting trial dates. Ask early about tolling, late-registration options, and required diagnosis records. A lawyer can check which state rule applies and which MDL order governs your filing.
What do verdicts and case counts mean for you?
Pending counts show where courts are spending resources. AFFF litigation had about 15,240 personal-injury cases pending in July 2026, with no personal-injury settlement announced and injury claims in court-ordered mediation. Roundup still had 4,508 lawsuits pending on December 3, 2025, after a Georgia jury awarded nearly $2.1 billion to John Barnes in March 2025, according to the December 2025 case update. A large verdict does not pay other plaintiffs automatically.
It tests evidence themes, damages arguments, and defense strategy before later trials or settlement talks. Bellwether trials can therefore raise or lower settlement value without deciding every case. GLP-1 litigation had about 3,848 gastrointestinal-injury cases pending on July 1, 2026 against Novo Nordisk and Eli Lilly, according to the 2026 MDL status report. New filers should watch the September 2026 expert hearings because those rulings can narrow which injuries proceed.
What should you ask before signing?
Bring records to the first review and ask how the firm handles screening. Useful questions include what diagnosis qualifies, what exposure proof is needed, who pays costs if the case loses, and how fees work.
Also ask about tolling, required diagnosis records, bellwether effect, and court deadlines for your specific MDL. Get the answers in writing, keep copies of medical and work records, and do not wait past the limitations check.
