These residues contain energetic compounds such as 2,4-dinitrotoluene and nitroglycerin. Data on the accumulation of these compounds in surface soil were needed for environmental monitoring of potential contaminants at military training ranges in Alaska. Propellant residues from training exercises were collected and characterized. The residues consisted of discrete solid fibers or fragments of partially consumed propellant grains or flakes. Burning of excess propellant (especially on snow) left copious amounts of unburned propellant grains as well as charred residues. Sampling methods were developed and implemented to monitor the accumulation of 2,4-dinitrotoluene and nitroglycerin in the surface soils of firing points. Concentrations ranged from low parts per million of 2,4-dinitrotoluene at howitzer firing points and nitroglycerin at mortar firing points to part-per-thousand concentrations of nitroglycerin at anti-tank and 40 mm grenade firing points. %8 2012-12-03
