2024
Résumé:
This licence has been issued for the scientific research application No. 5765.
The main objectives of the field work for 2023 will be (1) to determine if the Ekati Diamond Mine is having an effect on the surrounding aquatic environment, wildlife, and air quality; and (2) to provide baseline data for areas where mine development may occur in the future.
In winter, water samples will be colle...

Résumé:
This licence has been issued for the scientific research application No.5534.
The long-term objective of this research is to determine what processes control the recovery of the landscape near Yellowknife that was contaminated by stack emissions from the Giant Mine roaster, and how this recovery will be affected by climate change and unusual or severe weather events. One focus will be on how cl...

2015 Résumé:
The objectives are to evaluate if there are differences in biological parameters among study sites and between years at the Tungsten Mine site; as well as to determine whether observed differences from the most recent (2015) Environmental Effects Monitoring study are still present and whether any differences are the result of mining practices.
The study objectives are to evaluate fish health, ...

2016
Résumé:
The main objectives of this research project are to determine if macroinvertebrate community structure and composition is changing over time in freshwater streams in the South Nahanni watershed; and, to determine whether mining activities degrade the health of streams in the South Nahanni Watershed and define zones of degradation due to mining activities. These test sites are downstream of mines.

To revisit fixed sample stations at near-field, mid-field and far-field sites over the course of the year in an effort to determine any seasonal variation that may exist and confirm impact predictions. The study will encompass the following water based parameters: water quality, zooplankton & phytoplankton biomass and taxonomy, benthic invertebrate analysis and sediment chemistry. This program als...

Résumé:
The objectives of this project will be (1) to characterize the geochemistry of the Prairie Creek paste backfill, (2) identify whether the cement binder reduces potential for oxidation, (3) examine the site specific conditions of the backfill within the underground mine workings, (4) identify the potential for chemical reaction between the wall rock and backfill and possible impacts, and (5) evalua...

2010 Résumé:
The objective of this study is to examine the health of two small-bodied fish species (Slimy Sculpin and Ninespine Stickleback) exposed to treated effluent from Giant Mine. Data collected during this study will be assessed to determine if there are treated effluent related effects. The study will be conducted within the exposure areas (Baker Creek and Yellowknife Bay) and the reference areas (Yell...

2010200920082005 Résumé:
This research study is designed to investigate the processes related to water quality and quantity (collected at different scales) draining from country rock stockpiles that are located in areas of continuous permafrost. The quality of water draining from a country rock stockpile is determined by the combined effects of oxygen transport in the air phase, biogeochemical processes that control miner...

20072006200520042003 Résumé:
This research will characterize baseline and post-baseline conditions in the lakes and streams near areas of current and pending mining activity. This will be the 11th year of post-baseline data collected in the Koala Watershed and the 8th year of post-baseline data collected in the King-Cujo Watershed as a part of EKATI’s Aquatic Effects Monitoring Program. It will also be the 10th year of monito...
