Presumptive exposure programs

If your service matches one of these, the VA presumes the connection — you don't have to prove the hazard caused your condition. Start here.

PACT Act — Burn Pits & Airborne HazardsService in these locations creates a presumption of exposure to burn pits and other airborne toxins. You do not have to prove exposure, only qualifying service plus a diagnosis.Agent Orange / HerbicidesService in these locations and dates presumes exposure to Agent Orange and other tactical herbicides.Camp Lejeune Contaminated WaterAt least 30 cumulative days at Camp Lejeune or MCAS New River in the qualifying window presumes exposure to the contaminated drinking water.Gulf War Illness (Undiagnosed & Chronic Multisymptom)Southwest Asia and Afghanistan service presumes service connection for medically unexplained chronic illnesses that appear to a compensable degree (by December 31, 2026 under current rules).Ionizing Radiation (Atomic Veterans)Participation in atmospheric nuclear testing, the occupation of Hiroshima or Nagasaki, or other radiation-risk activities presumes exposure for a list of radiogenic cancers.

Documented exposures (evaluated case-by-case)

Not a blanket presumption — you establish the exposure and a medical nexus. A free VSO can help build it.
