Independent Third-Party Review of the Aquatic Effects Monitoring Program (AEMP) (Zajdlik & Associates, 2005)
~2005Report
Approximate date — inferred from filename
Independent 3rd-party review of the Ekati Diamond Mine's Aquatic Effects Monitoring Program (AEMP) conducted by Zajdlik & Associates for 2002 monitoring data, evaluating statistical treatment of nitrate, copper, and zooplankton measurements to assess environmental changes downstream of the Low-Level Containment Facility. The review identifies strengths in BHPB's comprehensive monitoring program while recommending improvements in data handling procedures, alternative statistical approaches, and use of gradient and multivariate analyses.

Panda Diversion Channel Monitoring Program Technical Report, Ekati Diamond Mine (BHP Billiton, January 2003)
1 January 2003Report
This technical report presents findings from the 2002 Panda Diversion Channel (PDC) Monitoring Program at the Ekati Diamond Mine, documenting hydrology, fish communities, habitat stability, and benthic and periphyton communities in the channel designed to compensate for habitat lost to mining operations. The 2002 monitoring year was characterized by low spring precipitation and peak flows, yet Arctic grayling continued to extensively utilize the PDC for spawning and migration with the second-highest numbers recorded since monitoring began in 1998.

Aquatic Effects Monitoring Program (AEMP) Re-evaluation and Refinement Report, Proposed Program for 2003–2007, Ekati Diamond Mine (BHP Billiton, October 2002)
1 October 2002Report
This AEMP re-evaluation and refinement report for the Ekati Diamond Mine proposes modifications to the aquatic effects monitoring program for 2003-2007, including assessments of sampling locations (Grizzly, Leslie, and Little Lakes), annual and seasonal monitoring frequencies, quality assurance/quality control procedures, and evaluated parameters. The document evaluates whether water quality changes in Grizzly Lake result from fugitive dust or ANFO leaching, recommends adding Leslie Lake and reconsidering Vulture Lake as reference sites, and proposes reducing seasonal phytoplankton and zooplankton sampling from three times per year to August-only collection while maintaining other monitoring frequencies.
