Recognized Military Toxic Exposures
Plain-English guides to the exposures VA recognizes — what zones and dates qualify, which conditions are presumptive, and what evidence to gather.

Each exposure has its own statutory framework — the PACT Act, 38 CFR § 3.307–.309, the Camp Lejeune Justice Act, and others. Pick the closest match to your service to see covered locations, qualifying dates, the presumptive condition list, and the evidence that strengthens your claim.

Direct-Claim & Emerging Exposures

Not sure which exposure applies?
Many veterans qualify under more than one framework. A free 30-minute consultation will identify which presumptions fit your service history.
Educational content only — not legal or medical advice. Recognized exposures, qualifying service dates, and presumptive condition lists change as Congress and VA update them.
