Ammonium Nitrate (AN) and Kodiak Lake Study, Ekati Diamond Mine (BHP Billiton, March 2005)
This 2004 environmental assessment examines whether ammonium nitrate storage facility operations and surface runoff were affecting Kodiak Lake at the Ekati Diamond Mine. The study documents that remediation efforts since 2002 have successfully reduced nitrogen compound concentrations entering the lake, with measurable but small localized effects constrained to two small bays receiving surface flow, showing elevated phytoplankton biomass but no adverse impacts on zooplankton or water quality parameters.
