Summary: This licence has been issued for the scientific research application No.5077. Ironstones are marine biochemical sedimentary rocks with >15 wt.% Fe that commonly occur together with phosphorites. Phosphorites are chemical sedimentary rocks that form in response to coastal upwelling. An exceptionally large accumulation of phosphatic ironstones is located in the Rapid Creek Formation within the no...

Principal Investigator: Stepney, Jessica
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.5051. This project will collect additional environmental and geotechnical samples to complete the remedial design. The former Stark Lake Uranium Exploration site has undergone multiple investigations over the years, and a data gap analysis has indicated that there is additional information required to complete the remedial ...

Principal Investigator: Boa-Antwi, Kofi
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.5016. The goal of this project is to determine whether dust generated from mining activities is causing a measurable change in dust deposition to and/or metals uptake in lichen closer to and further from the mine. If a significant difference in uptake is noted closer to versus further from the mine, a health risk assessment...

Principal Investigator: Evans, Marlene S.
Licensed Year(s): 2020 2019
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...

Principal Investigator: Gammon, Paul R
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...

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...

Principal Investigator: Wolfe, Brent BBW
Licensed Year(s): 2019 2018
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...

Principal Investigator: Chételat, John
Licensed Year(s): 2019 2018
Summary: This study will assess the present-day and future stability of legacy arsenic contamination stored in Yellowknife Bay sediments that originated from local gold mining activities. Using a combination of quantitative methods (field measurements, laboratory experiments, paleolimnology and mass balance modelling), the research team will estimate the diffusion of arsenic from sediments to overlying wat...

Licensed Year(s): 2018 2017 2016 2015 2014 2013
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,...

Principal Investigator: Dudley, Judy
Licensed Year(s): 2018
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...
