Abstract
To ensure a high degree of preparedness of military troops for any mission, training with live weapons is an important part of the military activities. As a result, many ranges and training areas are contaminated with energetic materials. Propellant residues accumulate at firing positions and projectile filling may be spread near the targets. That represents a concern for the Department of National Defence since military personnel can be exposed to these compounds which eventually may be transported to the surface waters as well as groundwater. Currently, there is no official protocol for routinely removing explosive residues from surface soils. If a procedure were implemented, the future impacts to groundwater could be reduced. Trials were carried out to find an simple, low-cost, in-situ method that allows the destruction of energetic materials on surface soils, especially at firing positions, where no vegetation is present. The goal was to determine whether combustion of selected products on the surface would be sufficient to raise the temperature beyond the thermal decomposition temperature of the compounds of interest (energetic materials) in the surface and sub-surface soil. Burnings were carried out on contaminated soil and the presence of explosives was monitored by high pressure liquid chromatography before and after the thermal treatment. Results showed that a gelled ethanol fuel is promising for the remediation of surface soils contaminated by energetic materials (E
