Investigation of the Fate of Wastewater Phosphorus within the Processed Kimberlite Containment Area, Ekati Diamond Mine (University of Alberta, 2002)
19 February 2002Report
This Master of Science thesis by Karen Patricia Graham investigates the adsorption of phosphorus from wastewater effluent onto kimberlite tailings in BHP's Ekati Diamond Mine's processed kimberlite containment area through controlled laboratory isotherm studies. The research determines that approximately 0.5 kg of dried kimberlite per litre of wastewater effluent is needed at 18°C to reduce phosphorus concentration from 10 mg/L to 0.1 mg/L, with results showing that coagulant and flocculant addition does not affect phosphorus adsorption, and pH and temperature changes do not cause desorption.

Lake Bottom Sediment Quality in the Coppermine River Basin (University of Waterloo, January 2002)
23 January 2002Presentation
This research presentation investigates lake bottom sediment quality as an environmental indicator in four lakes of the Coppermine River basin headwaters, analyzing metal concentrations, sedimentation rates, and metal enrichment to determine anthropogenic and natural sources of contamination. Findings show elevated concentrations of several metals exceeding sediment quality guidelines, with lead and mercury enrichment attributed to long-range atmospheric transport, informing sediment quality targets and recommendations for policy development to reduce anthropogenic metal release.

Kodiak Lake Sewage Effects Study Technical Report, Ekati Diamond Mine (BHP Billiton, January 2002)
1 January 2002Report
This technical report presents results of the 2001 Kodiak Lake Sewage Effects Study, the second year of follow-up monitoring after a three-year specialized study (1997-1999) examining effects of treated sewage effluent discharge on the lake's aquatic ecosystem. The study found that Kodiak Lake has mostly recovered from eutrophication caused by past nutrient introduction, though current project activities (particularly the Panda Diversion Channel) continue to introduce elevated nitrate concentrations.
