Teck Cominco Metals Ltd Aquatic Ecological Risk Assessment
Author: S. Swanson
Aquatic component of a five-year Ecological Risk Assessment (ERA) near Trail BC (Lower Columbia River) as the basis for a Wide Area Remediation Plan for under the BC Contaminated Sites Regulations (CSR). Used a weight-of-evidence (WOE) that incorporated both top-down and bottom-up lines of evidence. The aquatic risk management objectives are: 1. Minimize, now and in the future, smelter operation-related direct and indirect effects within the AOI on the diversity of aquatic plant (algae) and animal (benthic invertebrate) communities in the Columbia River and its tributaries. 2. Minimize, now and in the future, smelter operation-related direct and indirect effects within the AOI on fish populations in the Columbia River and its tributaries. 3. Prevent, now and in the future, smelter operation-related direct and indirect effects on threatened and endangered aquatic species (e.g., white sturgeon) in the AOI.
