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...

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...

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...

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...

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 ...

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...

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 ...

Summary: The seven-year objective of Sub-Arctic Meteal Mobility Study (SAMMS) is to identify, quantify, and predict mobility of natural-source and legacy mine-source metals in soil, wetlands, and lake sediments that extend from former, present, and planned mine sites currently and as climate change alters the quantity and quality of dissolved organic matter produced and exported in subarctic NWT watersheds...

Summary: The objective of this project is 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 Aquatic Effects Monitoring Program (AEMP) Version 3.5 will consist of the following components; Traditional Ecological Knowledge, Dust Deposition; Effluent an...

Licensed Year(s): 2018
Summary: The objectives of this research project are 1) to discover what knowledge residents have about local environmental contamination; 2) to discover what local residents believe about the risks to themselves and their families of living near areas of environmental contamination; and 3) assess the adequacy and effectiveness of information programs designed to provide information to the public concernin...
