“Thousands of people who may have been exposed to chemical or biological agents during military tests remain unaccounted for, and the Defense Department and Department of Veterans Affairs have given up on tracking them down, according to a new report.

Some of the tests were conducted as part of a weapons testing program known as “Project 112,” in others, individuals were intentionally exposed to hazardous substances such as blister, nerve, and biological agents as well as LSD and PCP, according to a Government Accounting Office report (PDF).

Any veteran who believes they sustained a disabilities from exposure during testing may file a claim for compensation with VA. The DOD stopped actively searching for test subjects in 2003 “but did not provide a sound and documented basis for that decision,” the GAO reported. At the time, it had identified 5,842 service members and about 350 civilians as having been potentially exposed during Project 112 alone (PDF). It is estimated that tens of thousands of military and personnel and civilians may have been exposed over the last 60 years.”
