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(More)
The potential for generation of environmental contamination in the form of residual munitions constituents during live-fire training activities on military ranges is a significant concern. The objectives of this project were to determine the nature and distribution of the potential contamination and to define transport properties of the constituents.(More)
Aluminum powder is a common ingredient in energetic materials. The aluminum is used to increase the energy and raise the flame temperature in rocket propellants. It is also incorporated in explosives to enhance air blast, increase bubble energies in underwater weapons, raise reaction temperatures and create incendiary effects. In explosives, it is generally(More)
DRDC Valcartier is actively working on the assessment of the extent of energetic materials contamination on Canadian DND training ranges. This work is carried out with the objective of creating sustainable training conditions for the Canadian Forces. As part of this effort, research is being undertaken to study, in laboratory conditions, the leaching of(More)
Ultrafine aluminum and boron powders have been identified as very promising fuels as part of energetic materials formulations. However, the large specific surface area that gives these powders a high reactivity also makes them particularly difficult to maintain in an unoxidized state. They also agglomerate easily during compounding processes. The coating of(More)
Ultrafine aluminum powders have been identified as very promising fuels for novel energetic materials formulations. However, the large specific surface area that gives these powders a high reactivity also makes them particularly difficult to maintain in an unoxidized state and different coating processes have been proposed to solve this problem. The(More)
We evaluated the impact of the ring-billed gull (Larus delawarensis) on the microbiological quality of water. We measured fecal coliforms, Salmonella spp., and Aeromonas spp. in the gull droppings and the number of fecal coliforms in the water prior to and after attracting these birds to the beach with food. Gulls can contribute to the bacteriological(More)
