    Toxic Exposures

    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.
