Taltson Twin Gorges Hydro Generating Facility Aquatic Effects Monitoring Program (AEMP) 2019
Principal Investigator: Miller, Matthew
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4565. The objective of this project is to conduct Aquatic Effects Monitoring. This will include three parts: 1) Riparian Habitat and Fish Usage Assessment. This is a study to monitor the trends and fluctuations of the aquatic environment along the riparian zones within the Taltson River from Nonacho Lake to Twin Gorges ...


Sanguez Lake Fish Down Study
Principal Investigator: Low, George
Licensed Year(s): 2019 2018 2017
Summary: This licence has been issued for the scientific research application No.4573. The objectives of this study are to: 1) establish a population estimate of walleye in Sanguez Lake; 2) establish an additional estimate of fish mercury concentrations in walleye and pike. In 2013, mean mercury concentration in walleye was 0.71 mg/kg wet weight, and in pike was 1.09 mg/kg wet weight; 3) reduce the n...


Spatial and long-term trends in persistent organic contaminants and metals in fish from the Northwest Territories
Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4533. This study will investigate whether contaminant levels are changing in fish in Great Slave Lake which the research team have been studying since the early 1990s. The team plan to collect lake trout from the Hay River and Lutsel K’e areas. The team will also collect burbot from the Lutsel K’e and Fort Resolution areas ...


Nutrient and contaminant status in the wetlands of the Slave River Delta
Principal Investigator: Doig, Lorne
Licensed Year(s): 2019
Summary: Through this research the team will answer the following questions: 1. From the outer Slave River Delta (SRD) to the apex of the SRD, what is the current status of nutrients and contaminants in SRD wetland ecosystems? 2. How do trace elements (e.g., mercury) move through SRD wetland food webs? 3. How does water source affect the availability of nutrients and trace metals in SRD wetlands? Wet...


Temporal trend studies of trace metals and halogenated organic contaminants (HOCs), including new and emerging persistent compounds, in Mackenzie River burbot, Fort Good Hope, NWT.
Principal Investigator: Stern, Gary
Licensed Year(s): 2019
Summary: The short-term goals are to determine if 2019 burbot contaminant concentrations: 1) remain below Health Canada guidelines (i.e. <0.5 ppm mercury per gram fish); 2) are associated with dietary indicators to determine the influence of diet (via stable isotope ratios) on contaminant concentrations in current fish, although previous results suggested no association; and, 3) as well as to look for link...


Health Effects Monitoring Program
Principal Investigator: Chan, Laurie H. M.
Licensed Year(s): 2019 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...


Remediation of the Abandoned Panarctic Satellite F-68 Wellsite at Satellite Bay, Prince Patrick Island, Northwest Territories
Principal Investigator: Krizan, Julia
Licensed Year(s): 2019 2018 2017 2016 2015 2013 2011 2010
Summary: The objectives of the Site Remediation Program (scheduled to be completed in 2019 and 2020) are: 1) to remove and dispose of exposed historic solid waste (including barrels, batteries, debris, wood and other waste); and 2) to finalize construction of a contaminated soil and waste containment structure to contain impacted soil excavated from areas at the site. The 2019 Site activities may includ...


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
Licensed Year(s): 2019 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 ...


TERRE-NET: Controls on the Release of Contaminants from Gold Tailings at the Giant Mine, Yellowknife, NT
Principal Investigator: Blowes, David W.
Licensed Year(s): 2019 2018 2017
Summary: The goals of this research are: 1) to determine the magnitude and rate of release of arsenic and other toxic elements from the Giant Mine tailings to groundwater; 2 to evaluate remediation alternatives for tailings management, including the effects of proposed engineered covers; and, 3) to apply novel characterization techniques to understand the mechanisms controlling arsenic release. The r...


Identifying sources of mercury in Arctic rivers
Principal Investigator: Zdanowicz, Christian M
Licensed Year(s): 2019 2018
Summary: The goal of this project is to identify and quantify (measure) the different possible sources of toxic mercury that is transported in rivers of the Mackenzie River basin, all the way down to the Beaufort Sea. In particular, the research team want to establish how much mercury comes from "modern" sources (like distant air pollution, runoff from rain/snow, wash-out from surface soils, etc.) and how ...
