Toxic exposure: Burn pits
Burn Pits and VA Disability Claims
Burn pits were open fires the military used to get rid of trash on bases overseas. Tires, plastic, metal, and medical waste were burned in the open air. The smoke carried fine particles and toxic chemicals that troops breathed every day.
The PACT Act made many burn-pit conditions presumptive. If you served in a qualifying place, the VA accepts the link and you do not need a nexus letter. If your condition is not on the list, or your service does not match, you can still win by direct service connection.

What burn pits were, and what was in the smoke
From the Gulf War through the wars in Iraq and Afghanistan, large burn pits ran day and night on many bases. Jet fuel was often used to keep them burning. The smoke was a mix of fine particulate matter, dioxin, benzene, and other toxic compounds.
Fine particles lodge deep in the lungs. That is why asthma, rhinitis, and sinusitis are now presumptive for burn-pit service. The dioxin and benzene in the smoke also tie to several cancers. If a cancer is not on the burn-pit list, the cross-walk below may still connect it.
Who qualifies, and what it means for you
If you meet the rule and have a listed condition, this is likely presumptive and you do not need a nexus letter. If not, there is still a path. Check yours.
Are you in the presumptive window?
Check the rule and your condition. Two answers and you will know whether this is likely a presumptive claim or one that needs a nexus letter. Orientation only, not a claim decision.
Who qualifies
Gulf War and post-9/11 theaters, including Iraq, Afghanistan, and other recognized locations.
The PACT Act presumes airborne-hazard exposure for qualifying service in these areas.
Where this exposure can still win a claim
Many conditions are tied to the specific chemicals you were exposed to, not just to a program name. That is the opening when you are not presumptive.
The chemicals you were exposed to, and what they cause
Burn pits and airborne hazards carries chemicals that also show up in other exposures. Some conditions they cause are already presumptive for a different program. If you have one of these and you are not presumptive here, you are not stuck. The same science can support a direct service-connection claim, which is exactly what a nexus letter is for.
Also found in: burn-pit smoke, sand, dust, and oil-well-fire smoke.
Linked conditions
- Asthma
- Chronic rhinitis
- Chronic sinusitis
Already presumptive under PACT Act (burn pits). If you were exposed to fine particulate matter a different way, you do not get that presumption, but a physician can connect these conditions to your exposure with a nexus letter. It is decided case by case, which is why the medical opinion matters.

Also found in: Agent Orange, plus the smoke from burn pits, diesel exhaust, and jet-fuel combustion.
Linked conditions
- Ischemic heart disease
- Parkinson's disease
- Soft-tissue sarcoma
- Non-Hodgkin's lymphoma
- Chronic B-cell leukemias
- Type 2 diabetes
Already presumptive under Agent Orange. If you were exposed to dioxin (tcdd) a different way, you do not get that presumption, but a physician can connect these conditions to your exposure with a nexus letter. It is decided case by case, which is why the medical opinion matters.

Also found in: jet fuel, burn-pit smoke, and the contaminated water at Camp Lejeune.
Linked conditions
- Acute myeloid leukemia
- Myelodysplastic syndromes
- Multiple myeloma
- Non-Hodgkin's lymphoma
Already presumptive under Camp Lejeune. If you were exposed to benzene a different way, you do not get that presumption, but a physician can connect these conditions to your exposure with a nexus letter. It is decided case by case, which is why the medical opinion matters.

This shows possible pathways, not a decision on your claim. Whether a condition connects to your exposure is a medical judgment, made case by case. It is not medical or legal advice.
How a nexus letter fits
When a claim is not presumptive, you win it by direct service connection. Under 38 CFR 3.303, that needs three things: a current diagnosis, an in-service exposure, and a medical opinion tying them together.
The opinion has to clear one standard: “at least as likely as not,” a 50% or better chance the condition is tied to service. That comes from the benefit-of-the-doubt rule in 38 U.S.C. 5107(b), carried out in 38 CFR 3.102. The PACT Act goes further: for a non-presumptive condition tied to a qualifying toxic exposure, the VA must order an exam and a medical opinion. That opinion is the nexus, and it is what we write.

Secondary conditions
A breathing condition from burn pits can lead to sleep apnea, which is also ratable. A cancer can lead to depression. These secondary claims are often missed, and we look for them.
Frequently asked questions
Do I need a nexus letter for a burn-pit condition?
Not if it is presumptive. If you served in a qualifying place and have a listed condition, the VA accepts the link. If your condition is not listed, or your service does not match, a medical nexus is how you win.
Where do I qualify for the burn-pit presumption?
Service in the Gulf War and post-9/11 theaters, including Iraq, Afghanistan, and other recognized locations. The PACT Act presumes airborne-hazard exposure for that service.
My cancer is not on the burn-pit list. Can I still claim it?
Yes, by direct service connection. The smoke carried dioxin and benzene, which are tied to several cancers. A doctor can connect your cancer to that exposure with a nexus letter.
What is the Airborne Hazards and Open Burn Pit Registry?
It is a free VA registry that records your exposure history and offers a health evaluation. Joining helps document your service, though you do not have to join to file a claim.
My burn-pit claim was denied. What now?
A denial is not the end. If a condition was added to the list after your denial, file a supplemental claim. If the problem was proof, the right evidence and a medical opinion can change the result.
Does Patriot Path help with burn-pit claims?
Yes, and we are most useful on the harder ones: conditions that are not presumptive and claims that were denied. The first consultation is free.
Were you exposed to burn pits and airborne hazards?
Let’s figure out your path together. The first consultation is free, and we will tell you straight whether a nexus letter can help your claim.
