Aquatic Effects Monitoring Program (AEMP) Technical Report, Ekati Diamond Mine (BHP Billiton, December 1999)
This 1999 Aquatic Effects Monitoring Program (AEMP) Technical Report documents the second year of post-baseline aquatic monitoring at the BHP Ekati Diamond Mine, covering lakes, streams, and sediments within the mine claimblock. The report identifies elevated nitrate concentrations in waterbodies downstream of the Processed Kimberlite Containment Area as the primary project-related effect detected in 1999, while noting that most other environmental parameters remained within acceptable ranges with no major adverse ecosystem impacts observed.
