The overall objective of this research project is to improve our ability to evaluate the environmental impact of mining wastes on aquatic ecosystems. This approach is based on furthering our understanding of the factors affecting metal bioavailability. The practical outcomes of this research project are: (1) an improved means of setting water quality criteria for mining-impacted streams; and (2) a rapid screening tool that can be applied in the field to evaluate the potential environmental impact of mine wastes. The research project has four specific objectives: (1) evaluation of the existing Biotic Ligand Model (BLM) for mining-impacted waters; (2) improvement of the BLM by examining the influence on metal toxicity of the unique nature of mining-impacted waters with respect to the hardness cations; (3) further development of the BLM to include mixed metals (Cu and Zn); and (4) development of a microbial bioassay to rapidly screen mine wastes to assess their toxicity potential.
