Evaluation of the Impacts of Live Fire Training at CFB Shilo
Abstract
This work describes the evaluation of the impacts of the training activities in CFB Sbilo training area and is the continuation of the first phase done in Sept 2000. During the first phase, three battleruns were sampled for energetic materials, metals, VOCs and petroleum products to measure their impacts on soils and biomass, as well as on subsurface soils, surface water and ground water in the training areas. Such an assessment required an appropriate definition and understanding of the geological and hydrogeological context of the site. During the second phase, the two remaining battleruns, the rifle and the grenade ranges were sampled according to procedures described in this report. Since some trends were encountered in phase I around target areas, more specific sampling, including biomass samples was conducted. Explosives, 232Thorium and heavy metals analyses revealed some localized problems related to environmental contamination and trends were observed that could be related to the firing activities. Some mitigation techniques are proposed for the identified problematic areas. Thorium analyses revealed a localized impact close to the targets both in surface soils and in ground water. The distribution of this chemical was not fully understood and more analyses were done at the end of the summer 2002 to establish if the concentrations in ground water are increasing or decreasing. Nevertheless, the concentrations of thorium in groundwater do not represent a threat being 10 times below the CCME criteria.
