NATCL Cantung 2017 EEM Program
Principal Investigator: Carson, Richard J
Licenced Year(s): 2017 2015
Summary: 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, ...


Assessment of the condition of freshwater streams in the South Nahanni watershed
Principal Investigator: Steedman, Audrey
Licenced Year(s): 2016
Summary: 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. ...


Diavik Aquatic Effects Monitoring Program
Principal Investigator: Wells, David A
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2005 2004 2003 2002 2001
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...


Predicting post-closure water quality at a mine in Nahanni National Park
Principal Investigator: Stavinga, Drew B
Licenced Year(s): 2013
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...


Con Mine Phase 4 EEM - Periodic Monitoring
Principal Investigator: Machtans, Hilary
Licenced Year(s): 2015 2012 2009 2007
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 ...


Waste rock studies at a diamond mine site
Principal Investigator: Blowes, David W.
Licenced Year(s): 2014 2013 2012 2011 2010 2009 2008 2005
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...


Improving Habitat Connectivity to Enhance Productive Capacity of Arctic Freshwater Ecosystems
Principal Investigator: Tonn, William
Licenced Year(s): 2014 2013 2012 2011 2010 2009
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 t...


Great Slave Lake Area Mines: Site Assessment And Remediation Planning
Principal Investigator: Wiatzka, Gerd M
Licenced Year(s): 2013 2012 2011 2010
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...


The presence and persistence of arsenic trioxide in soils around Giant Mine, NWT
Principal Investigator: Bromstad, Mackenzie J
Licenced Year(s): 2010
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...


Aquatic Environmental Effects Monitoring - Flat River at Cantung Mine
Principal Investigator: Hoos, M.Sc. R.P.Bio, Rick
Licenced Year(s): 2012 2009 2002
Summary: The objectives of this research are to: (a) determine length, weight, and general condition of 100 Slimy Sculpin (Cottus cognatus) per site at three site locations in the Flat River: one location upstream of the CanTung mine site and at two locations downstream of the mine site. The research will also determine length, weight, and general condition of any other incidental fish catches. (b) d...
