Summary: This licence has been issued for the scientific research application No.4818. This research will investigate whether contaminant levels are changing in fish in Great Slave Lake which the team have been studying since the early 1990s. The research team plan to work with commercial fishery and community collected lake trout from the Hay River and Lutsel K’e areas, burbot from the Lutsel K’e and F...

Licensed Year(s): 2019
Summary: This licence has been issued for the scientific research application No.4544. The objectives of this research are: 1) To investigate the environmental chemistry of the borrow pits and immediate surrounding areas to determine what, if any, environmental risk do the elevated concentrations represent; 2) To investigate the environmental chemistry of an undisturbed area around the Inuvik to Tukto...

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 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: Water quality monitoring equipment has been deployed at over 42 sites across the NWT to address community concerns. Community members were trained to use the following equipment: •YSI sondes: sit in the water and measure basic water quality parameters every 2 hours for up to 3 months. Analysis undertaken at ENR. •Grab water samples: measure basic parameters, nutrients, physicals, major ions,...

Summary: The purpose of the study is to verify baseline conditions within the Pine Point District study area. Field sites will be accessed by truck, on foot, and on ATVs during the ice-free growing season. The study may include analysis of previously disturbed sites to evaluate regeneration and succession, surveys of former mine pits, collection and analysis of surface water and groundwater samples, g...

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...

Licensed Year(s): 2017 2016 2015
Summary: The research team propose to develop tools to assess risks associated with legacy industrial developments in a northern setting. The team will investigate contaminants from the Giant Mine near Yellowknife Northwest Territories (NT), which operated between 1948 and 2004, producing a legacy of contaminants including arsenic, antimony, hydrocarbons, mercury, and others. This remediation strategy appl...

Summary: The objectives of this project are to collect fish tissue samples from species of subsistence importance to 1) establish a long-term community monitoring program for contaminants in fish; and 2) to monitor potential spatial and temporal trends in metal concentrations (including mercury) in fish tissues within the Yellowknife region. The data acquired will be added to existing and concurrently coll...
