The Honoring Our PACT Act expands the list of presumptions for Agent Orange exposure, making it easier for those who may have been exposed to herbicides during their time in service to receive benefits. The new law includes presumptions for Agent Orange exposure locations in Thailand, Cambodia, Laos, Guam, American Samoa, and Johnston Atoll. 

If you served in any of these locations during the Vietnam War and have since been diagnosed with a disease linked to Agent Orange exposure, you may now be eligible for disability benefits. 


Agent Orange Use: Most Commonly Recognized in Service Environmental Exposure During the Vietnam War

Agent Orange is a herbicide that was used during the Vietnam War to clear vegetation. It was later found to contain dioxins, which are highly toxic and can cause cancer, birth defects, and other health problems. 

Although Agent Orange was used throughout Southeast Asia during the war, it is most commonly associated with the Vietnam War. The U.S military sprayed over 19 million gallons of Agent Orange in Vietnam, Cambodia, and Laos from 1962-1971.

As a result, many war veterans have developed health problems related to their exposure to the toxic herbicide. 

VA Releases Updated List of Agent Orange Exposure Locations

The VA has updated its list of Agent Orange exposure locations where service members may have come in contact with the dangerous herbicide.

This information is important because it will help veterans get the necessary care and benefits. Service members exposed to Agent Orange may be at risk for various health problems, including cancer and other diseases. 

The VA will provide medical care and benefits to veterans who develop these conditions. 

The list of Agent Orange exposure locations includes Thailand, Cambodia, Laos, Guam, American Samoa, and Johnston Atoll. With this updated information, veterans can get the care and benefits they need and deserve.



The Pesticide Control Act of Thai Law bans Agent Orange and other toxic chemicals in Thailand. In particular, the PACT Act recognizes service members who served in any U.S. or Royal Thai military base in Thailand between January 9, 1962, through June 30, 1976, who were most likely exposed to Agent Orange. It is a welcome measure for the many veterans exposed to these dangerous chemicals while serving in the country during the Vietnam War. 


In late April 1969, about 270 square miles of French and Cambodian rubber plantations in Kampong Cham Province were covered by sprayed Agent Orange. This spraying was a part of the United States Secret War in Cambodia, which lasted from 1969 until 1973. The purpose of the spraying was to defoliate the area around the Ho Chi Minh Trail, which the North Vietnamese Army used to transport supplies and troops into South Vietnam. However, spray drifts from the spraying-affected areas outside the target zone, including Cambodian villages. 


Agent Orange was used extensively in Laos, but little testing has been conducted so the full extent of its usage is not yet known. The War Legacies Project did conduct a study that showed the rate of birth defects in Laos villages sprayed with chemicals was similar to the rates found in heavily sprayed Vietnam villages.

Guam or American Samoa 

Despite previous denials and debates about whether Agent Orange was used in Guam, there’s evidence that certain Agent Orange components were used during the Vietnam War. Although the full extent of its use is unknown, veterans stationed in Guam or American Samoa during the war were likely exposed to Agent Orange. 

Johnston Atoll 

In April 1972, the U.S. Air Force began storing Agent Orange on Johnston Island, a small island located off Hawaii’s southern shoreline. The Air Force continued to store Agent Orange on the island until September 1977. During this time, approximately 1.5 million gallons of Agent Orange were shipped to Johnston Island. While most of the barrels were properly stored and sealed, some of them leaked, causing contamination of the island’s soil and water. 


Other Benefits From the PACT Act for Veterans

In addition to the updated list of locations where service members may have been exposed to Agent Orange, The PACT Act expands eligibility for VA health care to post-9/11 combat veterans. It creates a framework for establishing future presumptions of service connection related to toxic exposure. 

Additionally, the PACT Act adds 23 burn pits and toxic exposure-related conditions to the VA’s list of service presumptions, including hypertension. 

The PACT Act also strengthens federal research on toxic exposure and improves VA’s resources and training for toxic-exposed Veterans. 

With the PACT Act, veterans exposed to toxic substances will finally have the support they need to get the care and benefits they deserve.
