The chemical agents stored at the two bulk-only sites differ substantially (HD mustard agent at Aberdeen, Maryland, and VX nerve agent at Newport, Indiana). Therefore, different treatment process sequences were selected for use at the two sites. In both processes, the chemical bonds associated with agent toxicity will be destroyed by hydrolysis (with water for HD or aqueous sodium hydroxide for VX) (NRC, 1996a). However, in order to achieve rapid and... 

The Newport, Indiana, stockpile contains 1,269 tons of VX nerve agent, a relatively nonvolatile, persistent toxin that disrupts signal transmission in the central nervous system. VX can be hydrolyzed in hot aqueous sodium hydroxide solution. This process produces a strongly alkaline solution containing salts of methylphosphonic acid, its monoethyl ester, and a foul-smelling thiol amine compound. In 1996, the NRC recommended further evaluation of the Army s... 

Neutralization-based technologies (alternatives to incineration) are being installed at the chemical stockpile site in Newport, Indiana, where bulk-only VX nerve agent is stored, and in Aberdeen, Maryland, where bulk-only mustard agent is stored. The selection of technologies for the last two sites, at Pueblo, Colorado, and Blue Grass, Kentucky, is under way. 

Improved chemical agent point detection system (IPDS). The IPDS also employs ion mobility spectrometry and is an improved version of a point detection system. In addition to G and VX nerve agents, the IPDS is designed to detect vesicant agent vapors. Because it is a shipboard instrument, it will be much larger and will need more power than portable IMS devices. 

Shipboard automatic liquid agent detector (SALAD). The technologies to be used in the SALAD have recently been reviewed, but no decision has been made on the final selection. The instrument is designed to be an automated, externally mounted liquid agent detector capable of detecting G-type and VX nerve agents as well as vesicant chemical agents.

A private company has experience testing the technology with dilute solutions of GB and VX nerve agents, and it achieved a very high destruction and removal efficiency using a laboratory-sized reactor. 

In the summer of 1969 came more bad news. VX nerve agent was leaking from a container at the American base on the Japanese island of Okinawa and twenty-three servicemen had been taken to hospital suffering from its effects. This was doubly serious, for not only did it further erode what little confidence remained in the adequacy of safety measures at chemical weapons bases, but the Japanese government had not even been aware that gas was based on its soil. The previous summer one hundred children playing on a nearby beach had collapsed with an unknown illness. The Pentagon immediately ordered the weapons to be removed from the island.

Although delivery systems for VX nerve agent were initiated during the 1950s, no system was standardized. In addition, many of the sarin delivery systems took longer to develop than planned and some were never standardized. 

Fig. 2-50. The first three steps of VX nerve agent production were completed in these structures at Newport, Indiana. The technological level of chemical engineering needed to make this agent is vastly more complicated than that required to make mustard and phosgene during the World War I era.
