Abstract

The partial detonation of munitions used in military exercises leaves behind energetic particles on the surface of soil. Energetic particles deposited by incomplete detonations can then dissolve and be transported by overland flow and potentially contaminate ground and surface waters. The objective of this study was to evaluate the mechanisms of transport of Composition B, a formulation that includes TNT (2,4,6-trinitrotoluene) and RDX (hexahydro-1,3,5- trinitro-1,3,5-triazine) during overland flow. The transport of Composition B was examined using a rill flume with three flow rates (165-, 265-, and 300-mL min-1) and four energetic particle sizes (4.75--9.51 mm, 2.83--4.75 mm, 2--2.83 mm, and <2 mm). After each erosion simulation, energetic particles remaining on the soil surface were measured along with energetics dissolved in runoff, in suspended sediment, and in infiltration. Smaller particle sizes led to greater transport in both solution and sediment. The properties of the energetic compounds also influenced transport. More TNT was transported in runoff than RDX, likely due to TNT's higher solubility and dissolution rates, however, overall, dissolved energetics in runoff and infiltration accounted for very little of the total transport. Most transport of Composition B was the result of the physical movement of energetic particles and flakes by erosion forces. This study's results allow for improved prediction of Composition B transport during overland flow. [ABSTRACT FROM AUTHOR]

Abstract

Command (i. e., static) detonation is critical for testing munitions early in the acquisition process, however its representation of energetic residues produced during live fire has not yet been assessed. Here we measured energetic residue deposition rates on snow from live fire of 60 mm and 81 mm IMX‐104 mortar munitions and then compared results with previous command‐detonation tests of the same munitions. Mean live‐fire deposition rates of IMX‐104 compounds were: 3800 mg NTO, 34 mg DNAN, 12 mg RDX, and 1.9 mg HMX per 60 mm cartridge (n=9); and 8000 mg NTO, 60 mg DNAN, 20 mg RDX, and 2 mg HMX per 81 mm cartridge (n=13). The predominant residue compound NTO was accurately estimated by command detonation for the 60 mm munition (p=0.92) but was significantly underestimated for the 81 mm munition (p<0.0001). The minor residues of DNAN and RDX were relatively well estimated by command detonation for the 81 mm munition (p=0.07 and p=0.014, respectively), but both were significantly underestimated (p<0.0001) for the 60 mm munition. Despite some of these differences, the ability demonstrated here for command detonation to predict live‐fire residue deposition rates to the correct order‐of‐magnitude supports its utility in assessing environmental impact.
