Under the direction of the U.S. Army's Chemical Materials Agency (CMA) and mandated by Congress, the nation is destroying its chemical weapons stockpile. Over the past several years, the Army has requested several studies from the NRC to assist with the stockpile destruction. This study was requested to advise the CMA about the status of analytical instrumentation technology and systems suitable for monitoring airborne chemical warfare agents at chemical weapons disposal and storage facilities. The report presents an assessment of current monitoring systems used for airborne agent detection at CMA facilities and of the applicability and availability of innovative new technologies. It also provides a review of how new regulatory requirements would affect the CMA's current agent monitoring procedures, and whether new measurement technologies are available and could be effectively incorporated into the CMA's overall chemical agent monitoring strategies.
