A protocol was defined for the preservation of 12 munitions Dinitrophenol DNP Cyclotrimethylene trinitramine, RDX 1,3,5-Trinitrobenzene, TNB 1,3-Dinitrobenzene, DNB 2,4-Dinitrotoluene, 2,4-DNT Trinitrotoluene, TNT 2,4,6-Trinitrophenylmethylnitramine, Tetryl Diphenylamine, DPA Nitrobenzene, NB 2,6-Dinitrotoluene, 2,6-DNT Nitroglycerin, NG and Picric Acid, PA in water samples. The samples were preserved by adding acetonitrile to achieve a 10 solution the adjusting of the pH to 3.5 with glacial acetic acid removing sediment by centrifugation storing in amber glass bottles cleaned according to specified instructions sealed with Teflon cap liners refrigerating at 4C and maintaining in the dark. The effectiveness of the protocol was demonstrated for munitions fortified in tap water and monitoring well water samples, and sediment-deionized water mixtures.
