Proper storage of deadly nerve gas agents at military facilities requires the use of monitoring devices to ensure the protection of base personnel and local communities from possible leaks. But the operators of the Blue Grass Army Depot in Kentucky allowed such leak detectors to be removed from underground igloos housing nerve gas munitions—a critical safety violation that existed for two years. The danger was only exposed after a chemical weapons monitoring specialist blew the whistle on the situation, prompting the U.S. Army’s inspector general to investigate the depot in 2006. The IG’s report, though, was withheld from the public until this week, after an advocacy group, Public Employees for Environmental Responsibility (PEER), finally won its three-year battle with the Army to release the Blue Grass findings.
