Aquatic Effects Monitoring Program (AEMP) Overview Report, Ekati Diamond Mine (BHP Billiton, March 1999)
This 1998 Aquatic Effects Monitoring Program (AEMP) overview report documents the first year of post-baseline monitoring at the Ekati Diamond Mine, assessing impacts on water quality, sediment quality, and aquatic organisms in lakes and streams across the Koala Watershed. The report concludes that while overall aquatic conditions remained largely pristine with no major adverse effects, some nutrient-related impacts were detected, particularly elevated nitrate concentrations downstream of construction activities and slight phytoplankton enhancement in lakes affected by treated sewage discharge.
