By National Research Council, Division on Engineering and Physical Sciences, Board on Army Science and Technology, Committee on Review and Evaluation of the Army Non-Stockpile Chemical Materiel Disposal Program

Chemical battle materiel (CWM) encompasses diversified goods that have been used in the course of 60 years of efforts by means of the U.S. to strengthen an ability for accomplishing chemical struggle. Non-Stockpile CWM (NSCWM) is materiel no longer incorporated within the present U.S. stock of chemical munitions and contains buried materiel, recovered materiel, parts of binary chemical guns, former creation amenities, and miscellaneous materiel. simply because NSCWM is saved or buried at many destinations, the military is constructing portable remedy structures that may be moved from web site to web site as wanted. initially, the military deliberate to increase 3 moveable remedy structures for nonstockpile chemical materiel: the swift reaction approach (RRS), the munitions administration equipment (MMD), and the explosive destruction approach (EDS).

This record supplementations an past file that evaluated 8 substitute applied sciences for destruction of the liquid waste streams from of the U.S. Army’s portable remedy structures for nonstockpile chemical materiel: the RRS and the MMD. This record evaluates an identical applied sciences for the destruction of liquid waste streams produced through the EDS and discusses the regulatory approval matters and hindrances for the mixed use of the EDS and the choice applied sciences that deal with the EDS secondary waste streams. even though it makes a speciality of the destruction of EDS neutralent, it additionally takes under consideration the power of posttreatment applied sciences to approach the extra dilute water rinses which are utilized in the EDS following remedy with a reagent.

Example text

In only one of the RMA tests was any intact RDX found in a solid residue. In all the RMA tests, the liquid effluent contained less than 1,000 ppm of RDX or other explosives. Although the explosion may destroy some of the chemical agent contained in the munition, the agent destruction products appear to arise primarily from the subsequent neutralization process. S. Army, 2001c). Other hydrolysis products were also present, suggesting that, at least with GB, most of the agent survives the blast and is destroyed by the neutralizing reagent.

In general, the EDS and MMD neutralents are similar apart from the concentrations of metal ions and explosivesderived organic compounds. The latter are likely to be destroyed by posttreatments that destroy MEA, because they are less stable chemically. The metal components may require stabilization or solidification before final disposal, especially if toxic metals such as lead or mercury are involved. The toxicities of the MMD and EDS-1 neutralents are discussed and compared in Appendix D. ” However, some munitions containing arsenic-derived chemical agents may also be encountered.

S. Army, 2001d). Table 2-5 summarizes the amount of liquid waste produced in test experiments and the effectiveness of the neutralization as judged by the amount of residual agent in the liquid effluents produced. 5 MMD and EDS neutralent component listings are not comparable because different sets of constituents were analyzed, the analysis detection limits were different, and the magnitude of operations/tests differed. As noted in Tables 2-1, 2-2, and 2-3, the analytical data are for neutralents from specific munition items.
