For many veterans, proving exposure to hazardous substances during military service has been one of the most frustrating parts of seeking VA benefits … Questions about where they served. What they were exposed to. Whether those exposures were documented. And whether the evidence is enough to support a disability claim.

While recent legislation like the PACT Act has expanded access to benefits for many veterans, one significant challenge has remained: seeing the information the government actually has about your military exposures. That may soon begin to change.

A new report from the U.S. Government Accountability Office reveals that the Department of Veterans Affairs is preparing to give veterans access to their own Individual Longitudinal Exposure Record (ILER), a database that tracks potential military environmental and occupational exposures throughout a service member’s career.

If implemented as planned, veterans could not only review their exposure history but also request corrections when information appears incomplete or inaccurate. For many disabled veterans, that could represent a significant step toward greater transparency.

What Is the Individual Longitudinal Exposure Record?

The Individual Longitudinal Exposure Record, commonly called ILER, was developed by the U.S. Department of Defense and the U.S. Department of Veterans Affairs to consolidate information about a service member’s potential environmental and occupational exposures.

Rather than relying on a single document or deployment record, ILER brings together data from numerous government systems to create a more comprehensive picture of where a veteran served and what hazards they may have encountered.

Information may include potential exposure to:

• Burn pits
• Airborne particulate matter
• Industrial chemicals
• Radiation
• Fuel and exhaust emissions
• Occupational hazards
• Other environmental exposure events documented during military service

Today, VA healthcare providers and disability claims personnel can already use portions of this information when evaluating veterans. However, veterans themselves generally cannot access the same records.

That lack of visibility has long frustrated many veterans trying to understand what information the VA is actually using during healthcare and disability decisions.

A Major Step Toward Transparency

According to the new GAO report, the VA plans to allow veterans to access their own ILER information and submit requests to correct inaccurate records, with implementation currently anticipated by October 2026. That may sound like a technical change. In reality, it represents something much larger. Transparency builds trust.

When veterans can see the same exposure information their healthcare providers and claims processors use, they are better positioned to:

• Understand their medical history.
• Identify missing or incorrect information.
• Have more informed conversations with healthcare providers.
• Prepare stronger documentation when filing disability claims.

While ILER will not automatically determine whether a claim is approved, having greater visibility into available records could help veterans better understand how exposure information fits into the larger claims process.

The Numbers Show Why This Matters 

The GAO report also highlights just how widespread toxic exposure concerns have become.

Since implementation of the PACT Act’s Toxic Exposure Screening program in 2022, the VA has screened approximately 6.8 million veterans. Of those veterans, roughly 3.2 million — nearly 48 percent — were identified as having at least one potential toxic exposure during military service. Those numbers reinforce what many veterans have known for years: Exposure-related illnesses are not isolated cases. They affect millions of former service members across multiple eras and branches of service.

Building on the PACT Act

This latest development doesn’t replace the PACT Act. Instead, it builds upon it.

Over the past several years, the VA has expanded eligibility for healthcare and disability compensation related to toxic exposures, making it easier for many veterans to receive benefits associated with burn pits, Agent Orange, Gulf War environmental hazards, and other service-related exposures.

As scientific understanding continues to evolve, access to accurate exposure records becomes increasingly valuable for both veterans and healthcare providers.

What Veterans Should Know … 

It’s important to understand what ILER is — and what it isn’t.

The database does not automatically prove that an illness was caused by military service.

Nor does it guarantee approval of a disability claim. Instead, it serves as one important source of information that healthcare providers and claims processors can consider alongside medical evidence, service records, examinations, and other documentation.

Veterans should also recognize that exposure databases continue to evolve as additional military records become available. That’s one reason allowing veterans to review and request corrections to their own records could improve overall data quality over time.

Why Access Matters Beyond Disability Claims 

While disability compensation often receives the most attention, access to exposure information has benefits beyond the claims process. Healthcare providers may use exposure history to guide preventive screenings, recommend specialized evaluations, or better understand potential long-term health risks. Veterans themselves may also gain a clearer picture of how past military service could influence future healthcare decisions.

Knowledge empowers both patients and providers. And when healthcare decisions rely on accurate information, everyone benefits.

Final Thoughts … 

For years, many veterans have wondered exactly what the VA knows about their military exposures. Soon, they may finally have the opportunity to find out.

Providing veterans with access to their own Individual Longitudinal Exposure Records represents more than a technological improvement. It represents a commitment to greater transparency, better communication, and stronger partnerships between veterans and the healthcare professionals who serve them.

As the VA continues implementing the PACT Act and expanding toxic exposure initiatives, giving veterans greater visibility into their own records is a logical next step. Because understanding your service history shouldn’t be limited to the government. Veterans deserve the opportunity to see it, understand it, and help ensure it’s accurate.

If you served in an environment where you may have been exposed to burn pits, hazardous chemicals, radiation, or other environmental hazards, consider speaking with your VA healthcare provider about toxic exposure screening and available healthcare services.
