Army destroys Spring Valley munitions
The U.S. Army Corps of Engineers on Friday began destruction of the first of a series of chemical and nonchemical munitions unearthed in recent months at the Spring Valley World War I chemical weapons site in Northwest Washington.
A 75-millimeter round containing the blistering agent, Lewisite, was placed inside a special Explosive Destruction System, located on federal property behind Sibley Hospital. Inside, explosives break open the shell and chemicals are pumped in to neutralize the toxic agent, said Dan Noble, the Spring Valley project manager. The process can take several hours.
The corps plans to destroy four more chemical munitions -- one containing mustard agent, three containing arsine -- in the coming days. Twenty more rounds that probably contain water are also slated for destruction, Noble said. Meanwhile, two containers of the toxic chemical arsenic trichloride that were unearthed in the area March 29 will be shipped from the discovery site, where they are packaged, to an Army lab at the Edgewood Arsenal on Monday, he said. The Army has been searching for, and removing, buried munitions at the former chemical weapons research station in Spring Valley since the 1990s.
