Abstract: Abstract: Field-contaminated soils from army ammunition plants, training ranges, and an explosive ordnance disposal area were used to determine the effect of machine grinding and extraction procedure on concentration estimates of energetics. Machine grinding for one minute did not degrade the major analytes of interest (HMX, RDX, TNT, or 2,4-DNT), but did significantly reduce the subsampling error. The platform shaker extraction procedure was found to be at least as efficient as the sonic bath method specified in SW-846 Method 8330 and is therefore a suitable substitute. Additional studies showed that extended grinding of the soil sample causes the sample to warm as a result of friction and results in analyte loss. However, grinding for five one-minute cycles, with a sufficiently long rest period between cycles to prevent soil warming, did not result in analyte loss. Repeated grind cycles were needed to reduce the subsampling error for soils contaminated with propellant residue.
