Aquatic Effects Monitoring Program (AEMP) 2020 Annual Report, Appendix C, Aquatic Response Framework, Ekati Diamond Mine (Arctic Canadian Diamond Company, January 2020)
This 2020 Aquatic Effects Monitoring Program annual report presents the results of comparing water quality and biological data to Aquatic Response Framework Action Levels for the Ekati Diamond Mine. The document identifies Action Level exceedances for four water quality variables (dissolved oxygen, chloride, total potassium, total phosphorus) and four biological variables (phytoplankton biomass, phytoplankton density, phytoplankton community composition, zooplankton community composition), and provides detailed summaries of existing Response Plans and their status.
