What You Were Exposed To Matters

Open burn pits were used across Iraq, Afghanistan, and the wider Gulf to destroy everything from plastics and metals to medical and human waste, often with jet fuel as an accelerant. The resulting smoke carried fine particulate matter, dioxins, and volatile chemicals deep into the lungs. Health effects the VA now connects to this include asthma first diagnosed after service, chronic bronchitis and COPD, chronic rhinitis and sinusitis, constrictive bronchiolitis, and several respiratory cancers. What to document: your base(s), the dates you were there, how close your quarters or work area sat to the pit, and any breathing problems that began during or after deployment.

Chemical exposure reaches far beyond Vietnam-era Agent Orange. It includes the tap water at Camp Lejeune (1953–1987), which was contaminated with industrial solvents TCE and PCE and the fuel additive benzene; pesticides used for base pest control; and solvents used to clean equipment. These are tied to reproductive cancers, kidney and bladder cancer, Parkinson’s disease, and other serious conditions. What to document: every base where you lived or worked, the years you were there, and any job that had you mixing, spraying, storing, or cleaning up chemicals.

Everyday military jobs carried their own toxic load. Asbestos lined older ships and barracks; lead-based paint coated countless buildings; AFFF firefighting foam (a source of “forever chemicals,” or PFAS) was used on flight lines and in fire training; and fuels, degreasers, and solvents filled motor pools and maintenance bays. These are linked to respiratory disease, kidney and other cancers, and thyroid problems. What to document: your MOS and any additional duties, the shops or vessels you worked in, and the materials you handled day to day.

Ionizing radiation exposure covers “atomic veterans” present at nuclear tests, personnel involved in the cleanup of radiologic sites (such as Enewetak Atoll or Palomares), those who handled nuclear weapons, and service members with X-ray, nuclear-medicine, or radar duties. It is tied to many cancers, including leukemia, thyroid, breast, and lung cancer. What to document: your radiation-related duties, any dosimetry (film badge) records, and the sites or vessels where you served.

This category includes nerve and blister agents (for example, the 1991 Khamisiyah demolition in the Gulf War that released sarin), depleted-uranium munitions and the dust from struck vehicles, and exposures during chemical-defense training. Related conditions range from Gulf War illness and unexplained chronic multisymptom illness to specific cancers. What to document: chemical-alarm or MOPP events you remember, your unit’s location during them, and any symptoms — fatigue, joint pain, cognitive fog, breathing trouble — that persisted afterward.

Contaminated water is its own distinct exposure, separate from the burn pits and the chemicals handled on the job. The best-documented case is Camp Lejeune, North Carolina, where the base drinking water was contaminated from 1953 to 1987 with the solvents TCE and PCE and the fuel additive benzene. Just 30 cumulative days stationed there can qualify a veteran — and family members who lived there — for VA care and disability benefits. The conditions tied to it include kidney and bladder cancer, several reproductive cancers, Parkinson’s disease, and other serious illnesses. Other installations have their own documented water and PFAS (“forever chemical”) contamination. What to document: every base where you lived, the years you were there, and any cumulative time at Camp Lejeune — even across separate assignments.

Military healthcare is its own exposure story, and it is one the VA almost never raises on its own. Nurses, medics, lab and blood-bank technicians, radiologic and nuclear-medicine techs, dental staff, surgical and OR personnel, and mortuary-affairs workers all handled toxic and carcinogenic substances as a routine part of the job: bloodborne pathogens; high-level disinfectants and cold-sterilants such as glutaraldehyde and ethylene oxide; waste anesthetic gases in operating rooms; hazardous antineoplastic (chemotherapy) drugs; formaldehyde and other fixatives in pathology labs and morgues; and repeated low-dose ionizing radiation from X-ray, CT, and fluoroscopy work. These are linked to respiratory disease and asthma, reproductive harm, blood and other cancers, and skin and neurological conditions. Because this exposure comes from the job rather than a named location, it is usually a facts-found (non-presumptive) claim. What to document: your medical MOS or AOC and the specific units and facilities you worked in, the substances and equipment you handled, any radiation dosimetry (film-badge) records, and any needlestick, chemical-spill, or exposure incidents recorded in your service treatment records.

Deployment to Southwest Asia and other regions carried a real risk of infectious and environmental diseases that can surface — or leave lasting damage — long after you come home. The VA recognizes a group of these as presumptive for Gulf War and post-9/11 veterans, including malaria, brucellosis, Campylobacter jejuni, Coxiella burnetii (Q fever), nontyphoid Salmonella, Shigella, mycobacterium tuberculosis, visceral leishmaniasis (sand-fly fever), and West Nile virus. Some, such as visceral leishmaniasis, can appear with no time limit at all. What to document: where and when you deployed, any illness or hospitalization during or after service, and lingering symptoms such as fatigue, fevers, joint pain, or neurological problems.
