The Rocky Mountain Arsenal (RMA) (Operable Unit 18) site comprises part of the 17,000-acre RMA site, which is a former U.S. Army chemical warfare and incendiary, munitions manufacturing, and assembly plant in Adams County, Colorado. From the 1950s until late 1969, the U.S. Army used the RMA facility to produce the nerve agent GB (isopropyl methyl- phosphonofluoridate). In addition, between 1947 and 1982, private industries manufactured various insecticides and herbicides. Since 1970, facility operations primarily have involved the destruction of chemical warfare materials. Thirteen Interim Response Actions (IRAs) were necessary prior to implementing the Final On-post Record of Decision (ROD). The ROD addresses interim remediation of source ares and management of migration. The primary contaminants of concern affecting the soil and ground water are VOCs, including benzene and TCE.
