Summary: 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...

Summary: 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...

Summary: The primary objective of the 2012 program is to obtain feedback from community members relating to Lac de Gras lake trout (Salvelinus namaycush) taste, texture, general condition and health. A secondary objective is to meet requirements set out in the Fisheries Authorization for Works or Undertaking Affecting Fish Habitat. Fish collection will primarily be conducted using nets set out on...

Summary: Year one of Periodic Monitoring under the Environmental Effects Monitoring (EEM) to determine if mine effluent is affecting fish and fish habitat. A small-bodied fish survey will be conducted within one exposure area (Jackfish Bay, Great Slave Lake) and one reference area (Horseshoe Island Bay). For consistency between phases, ninespine stickleback (NNST) will be targeted as one of the small ...

Principal Investigator: Harris, Katherine M.
Licensed Year(s): 2012 2010
Summary: 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...

Summary: The objectives of this project are: 1) to study the freshwater ecology, hydrology, and hydraulics of small lakes and streams in the Lac de Gras basin before habitat modification; 2) to monitor the changes in ecosystem productive capacity resulting from habitat modifications designed to increase habitat connectivity and fish passage; and 3) to assess the effectiveness of such habitat modifications ...

Summary: 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...

Summary: The objective of the Great Slave Lake Area Mines Site Assessment and Remedial Planning Program is to assist Indian and Northern Affairs Canada (INAC) with its ongoing work to clean up abandoned mine sites across the Northwest Territories. This will be accomplished through a series of Environmental Site Assessments followed by the development of a Remedial Action Plan (RAP). Samples will be col...

Summary: The objective of this project is to understand why arsenic trioxide (As3+) is still present in soils around Giant Mine, how long it will remain there, and if the set of circumstances leading to persistent As3+-rich soil may apply to any other places previously assumed to be As3+-free. In terms of current mine remediation, future human contact with the site, and ecosystem health, it needs to be und...
