It is a growing list that assists veterans who served on certain ships, especially Blue Water Navy Veterans, in determining if they may be eligible for a presumption of herbicide exposure. You can see our Navy ships on the Vietnam map right here! There are now more than 1,200 Navy ships that were deployed in waters contaminated by Agent Orange. As many as 9 million Americans live within five miles of a war zone, and nearly 3 million people live with some kind of health problem attributed to toxic exposures during these wars. The goal of the Presumptive Exposure Registry is to provide support to former shipboard residents who were exposed to herbicides during their service in the Vietnam War. The registry provides information about ships that were involved in the Vietnam War and lists those ships that meet specific criteria for consideration for status as "Agent Orange" ships. Those ships that qualify will receive a letter from the Department of Defense indicating that they should review their ship's records to see if it meets the requirements for presumptive status. If a ship does qualify, veterans who served aboard them would be presumed to have been exposed to herbicides. Ship names are listed in the registry along with their home ports. The registry also includes maps showing the locations in Vietnam where each ship was stationed at the time it was involved in Operation Ranch Hand.
