Health Effects Monitoring Program
Principal Investigator: Chan, Laurie H. M.
Licenced Year(s): 2018 2017
Summary: The Health Effects Monitoring Program is a human biomonitoring study aimed to assess the exposure and health impact of arsenic and other contaminants on the human population of Yellowknife, Ndilo and Dettah in the Northwest Territories, as part of the Giant Mine Remediation Project. The overall objective of the program is to establish current or baseline levels of arsenic exposure among residen...


A multidisciplinary investigation of recovery in Yellowknife area lakes from 50 years of arsenic pollution: What are the factors inhibiting recovery and the biological consequences?
Principal Investigator: Palmer, Mike
Licenced Year(s): 2018 2017
Summary: The overarching objectives of this research are two-fold: 1) to investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and 2) to investigate the toxicological consequences of...


Remediation of the Abandoned Panarctic Satellite F-68 Wellsite at Satellite Bay, Prince Patrick Island, Northwest Territories
Principal Investigator: Krizan, Julia
Licenced Year(s): 2018 2017 2016 2015 2013 2011 2010
Summary: The objectives of the Site Remediation Program (scheduled to be completed in 2018) are to: 1. Remove and dispose of exposed solid waste (including barrels, batteries, debris, wood, other waste and an existing building); and, 2. Construct a contaminated soil and waste containment structure to contain impacted soil excavated from areas at the site. The 2018 Site activities will include several in...


Toxic Effects of Chronic Arsenicosis in Muskrats and Squirrels from Yellowknife
Principal Investigator: Amuno, Solomon A
Licenced Year(s): 2017
Summary: The objectives of this research project are to: 1. investigate the effects of chronic arsenic exposure on reproductive parameters, specifically seminal and hormonal parameters including testicular pathology and os penis (baculum) morphology of small mammals (muskrats and squirrels) inhabiting the vicinity of the Yellowknife area, near the Giant mine, and in a reference location approximately 30-8...


Contaminant Biomonitoring in the Northwest Territories Mackenzie Valley: Investigating the Links Between Contaminant Exposure, Nutritional Status, and Country Food Use
Principal Investigator: Laird, Brian D
Licenced Year(s): 2018 2016
Summary: The overall objective of this research is to promote country foods in the Dehcho Region in a way that balances contaminant risks and nutrient benefits in order to maximize nutrient status while minimizing mercury exposure. The research team will work towards this objective through the implementation of research that will consist of the biomonitoring study to evaluate country food usage patterns, c...


EL494 Surface Water Monitoring Program 2016-2018
Principal Investigator: von Kuster, Jenica
Licenced Year(s): 2017 2016
Summary: The study is to continue to establish natural variations in the surface water conditions within the Exploration Licence (EL 494) area and monitor potential impact of oil and gas exploration activities. Surface Water Quality Sample Collection: Collect surface water samples once, during August 2017, from a reduced number of sampling locations targeted near areas where exploration activities have...


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, ...


TERRE-NET: Controls on the Release of Contaminants from Gold Tailings at the Giant Mine, Yellowknife, NT
Principal Investigator: Blowes, David W.
Licenced Year(s): 2017
Summary: The objectives of this research project are to: 1) determine the magnitude and rate of release of arsenic and other toxic elements from the Giant Mine tailings to groundwater; 2) evaluate remediation alternatives for tailings management, including the effects of proposed engineered covers; and, 3) apply novel characterization techniques to understand the mechanisms controlling arsenic release. ...


Paulatuk Whitefish Assessment
Principal Investigator: Ruben, Diane
Licenced Year(s): 2017 2016
Summary: The objectives of the research are to conduct an assessment of whitefish diet and contaminants. Two technicians will collect approximately 60 samples over 7 days at Billy’s Creek in July 2017 and an additional 60 samples at the Hornaday River in August 2017, collecting data on: species, location, date/time, catch effort/gear type, length, weight, sex, maturity, otolith, stomach content (frozen)...


Spatial and long-term trends in persistent organic contaminants and metals in fish from the Northwest Territories
Principal Investigator: Evans, Marlene S
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004
Summary: The objectives of this project are to: 1) continue to investigate trends in mercury, metals and persistent organic contaminants (POCs) in lake trout harvested from two locations (West Basin near Hay River, East Arm at Lutsel K’e) and burbot harvested from one location (West Basin at Fort Resolution) in Great Slave Lake in 2017 to further extend the long-term (1993-2015: POCs, 1993-2016 mercury a...
