Aquatic Effects Monitoring Program (AEMP) Overview Report, Draft, Ekati Diamond Mine (BHP Billiton, January 1999)
This is the 1998 Aquatic Effects Monitoring Program (AEMP) Overview Report for the Ekati Diamond Mine, documenting the first year of post-baseline aquatic monitoring. The report presents results from Tier 1 Core monitoring of lakes and streams and Tier 2 Special Effects monitoring, concluding that while overall water and sediment quality remained good with no major adverse effects, some nutrient enrichment was detected downstream of mine construction activities, particularly elevated nitrate in lakes affected by Long Lake dam construction and blasting operations.
