Abstract: Sustainment of training to maintain the readiness of our armed forces requires stewardship of human health and the environment. The objective of this project, initiated in FY00 and planned for completion in FY05, was to determine the potential for environmental contamination from residues of energetic materials on ranges. This report describes accomplishments for FY02. A U.S. and a Canadian site were characterized for explosives residues resulting from live-fire soldier training: Fort Bliss, Texas, and Canadian Forces Base (CFB), Shilo, Manitoba. Results are also reported on tests to determine residues associated with open detonations and low-order detonations and tests to define environmental fate and transport process descriptors. Results of intensive sampling at Fort Bliss indicated that judgmental sampling targeting low-order residues and firing points is superior to grid sampling for identifying potential point sources of contamination over the typically large training range areas. Furthermore, composite sampling offers the best opportunity of capturing a realistic concentration under the conditions of extreme heterogeneity. Results of open detonations tests confirmed that the use of C4 generates significant explosives residuals. In low-order detonation tests, controlling the percent energy yield of artillery projectiles proved difficult. Adjustments in the variables from these results will improve control of future detonation tests. At CFB Shilo, energetic materials found in soils were associated with targets, and propellants were associated with firing points. The Shilo ranges exhibited relatively low levels of contamination not requiring immediate corrective action. Results of soil partitioning tests demonstrated that pentaerythritol tetranitrate (PETN) and tetryl are degraded in surface and aquifer soils. While adsorption is relatively limited and will not impede transport, degradation may be sufficient to reduce transport of these explosives. Results illustrate the importance of soil properties in determining the transport potential for explosives. Study results provide data for estimation of firing range source terms, protocols for contaminant characterization, descriptions of residues from low-order detonations and from various UXO demolition procedures, and fate and transport process descriptors for energetic residues. These data support environmental compliance and training range sustainment.
