Objectif(s): The main objective of this study is to characterize environmental conditions and supplement existing environmental information for possible use in long-term (i.e., multi-year) Environmental Effects Monitoring (EEM) programs as required of the Giant and Con mines under recently developed federal regulations. Under the new Metal Mining Effluent Regulations (Fisheries Act), an EEM study is required to determine if mine effluent is affecting aquatic organisms in receiving waterbodies. Sampling will take place in areas that historically or presently receive mine effluent, as well as in reference areas (i.e., locations not exposed to mine effluent) for comparative purposes. The scope of environmental studies will include monitoring fish (growth, reproduction, survival, condition) and fish habitat, aquatic biota (benthic macroinvertebrate community), as well as water and sediment quality.
