Millions of veterans have been exposed to hazardous chemicals, contaminated water, burn pits, radiation, and other environmental toxins during military service.
If you developed a chronic illness after serving on a military base or deploying overseas, you may qualify for military base toxic exposure veterans disability benefits through the Department of Veterans Affairs (VA).
Thanks to the PACT Act, more veterans than ever now qualify for VA disability compensation, including many who were previously denied.

- The PACT Act added more than 20 new presumptive conditions and expanded qualifying locations.
- More than 3 million PACT Act-related claims have been processed since August 2022.
- Veterans can qualify through presumptive service connection or direct service connection.

What is Military Base Toxic Exposure?

Military base toxic exposure refers to contact with hazardous environmental substances during active duty, either on U.S. installations or in overseas deployments.
Common exposures include:
- Burn pits and airborne hazards in Iraq, Afghanistan, and other areas
- Contaminated drinking water, such as at Camp Lejeune
- Radiation exposure, including from nuclear testing
- Asbestos in military jobs or buildings
- PFAS (“forever chemicals”) at contaminated sites
- Jet fuel, industrial solvents, and other chemicals
These hazards have affected generations of veterans, with studies showing that 83.2% of post-9/11 deployed veterans reported at least one toxic exposure.

Common Symptoms of Toxic Exposure (Even Years Later)
One of the biggest challenges is that symptoms of toxic exposure often appear years or decades after service. Common delayed symptoms include:
- Chronic coughing or wheezing
- Shortness of breath
- Chronic sinusitis or rhinitis
- Fatigue
- Neurological issues (memory loss, tremors)
- Autoimmune disorders
- Skin conditions
- Cancers (lung, kidney, bladder, pancreatic, brain, and more)
Research published by the National Library of Medicine and VA links these to specific exposures. For instance, in a study, deployed military populations show prevalence rates of respiratory symptoms (e.g., chronic bronchitis and wheezing) among those with inhalational exposures.
If your symptoms started after service, consult a VA provider for a current diagnosis, which is key for VA claims.
How the PACT Act Expands Military Base Toxic Exposure Veterans Benefits
The PACT Act simplifies claims by presuming certain conditions are service-connected for qualifying veterans. Key changes include:
- Adding more than 20 presumptive conditions for burn pits, Agent Orange, and other toxic exposures, such as brain cancer, kidney cancer, asthma (diagnosed after service), COPD, chronic sinusitis, and pulmonary fibrosis
- Expanding locations for Agent Orange (e.g., Thailand, Laos) and radiation presumptives
- Streamlining the process, leading to higher approvals; as of Dec. 31, 2025, PACT Act-related claims have a 73% approval rate
- Mandating toxic exposure screenings for enrolled veterans in VA health care
Since its passage, millions of veterans have applied for benefits under these expanded rules. If your claim was previously denied, you may now qualify.

Military Base Toxic Exposure Benefits
Military Base toxic exposure can qualify you for a VA disability rating from 0-100%.
VA ratings are awarded based on the severity of your symptoms. Typically, the more your life is negatively impacted by your symptoms, the higher the rating percentage you’re awarded.
How Much Compensation Can You Receive?
The higher your VA rating, the higher your monthly tax-free compensation.
For 2026 rates (effective Dec. 1, 2025), a single veteran can expect between $180.42 (10%) and $3,938.58 per month (100%). Rates are higher with dependents.

Extras: Additional compensation may be available to you in the form of Special Monthly Compensation (SMC) for severe cases, dependent benefits, VA health care, and retroactive pay.
Establishing Service Connection
There are two main paths to approval: presumptive and direct service connection.
Presumptive Connection
You qualify automatically if you served in a qualifying location and timeframe, and you have a diagnosed presumptive condition — no nexus letter required.
Direct Service Connection
If your condition isn’t considered presumptive, you must show:
- A current medical diagnosis, and
- Evidence of in-service toxic exposure, and
- A medical nexus linking the two
Pro Tip: A nexus letter from a qualified medical professional can significantly strengthen your claim.

The VA Toxic Exposure Screening
The VA offers free toxic exposure screenings at facilities to document your exposure history and identify risks. It supports claims by strengthening your medical evidence but doesn’t grant benefits. More than 6.6 million screenings have aided early detection as of Dec. 31, 2025.
Next step: Schedule a toxic exposure screening through your VA provider or on My HealtheVet.
Step-by-Step: How to File a Military Base Toxic Exposure Claim
Step 1: Submit your Intent to File.
An Intent to File is exactly what it sounds like—it’s your way of telling the VA that you plan to submit a formal claim for benefits. But more than just a notice, your ITF locks in your effective date, which is key to receiving back pay.
Step 2: Gather Evidence
You’ll want to have your DD-214, records of deployments and duty stations, medical records showing a current diagnosis, buddy or lay statements (may be beneficial but not necessary), and a medical nexus (e.g., a nexus letter) if your condition is not presumptive.
Step 3: File Your Claim
You can file online at VA.gov, by mail or fax (VA Form 21-526EZ), or in-person with your regional VA office.
Step 4: Prepare for the C&P Exam
Your compensation and pension (C&P) exam is critical. Be sure to clearly describe your symptoms and explain how your condition impacts your daily life and work. Be open and honest, but don’t exaggerate or minimize the severity of your symptoms.
What if Your Claim Was Previously Denied?
Many veterans denied before the PACT Act are now being approved. If you were previously denied, you can file an appeal. There are three types of appeals:
- A Supplemental Claim, which includes new and relevant medical evidence or service records
- A Higher-Level Review, which reexamines the claim to look for errors
- A Board Appeal, which is more in-depth and can include new evidence depending on the docket selected
New medical evidence or a strong nexus letter often changes outcomes.

Why You Shouldn’t Wait to File
Delays in filing risk losing back pay and fading evidence. Policy changes could also affect eligibility.
Start today by scheduling a screening, gathering documentation, and submitting an intent to file. Filing protects your rights.
Conclusion
The expansion of military base toxic exposure benefits has opened the door for millions of veterans to receive the compensation and health care they earned.
If you served at a contaminated military base or in a qualifying deployment zone and developed health issues later in life, you may qualify — even if you were denied before.
The key is understanding how you qualify via presumptive/direct service connection, or a reopened claim strategy. The right evidence and education can make all the difference.

Military Base Toxic Exposure List

This list of military bases, depots, munition plants, airfields, and naval yards all comes from the Environmental Protection Agency’s (EPA) list of Superfund sites.
Superfund sites are locations the EPA has identified as contaminated by toxic substances and are now being cleaned up. “Superfund” is another name for the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), which was passed into law in 1980.
The law created a tax on chemical and oil companies used to help fund the EPA’s cleanup efforts. It also gave the EPA the authority to clean up contaminated sites and to require those responsible to either perform the cleanup or reimburse the government for cleanup costs.
