Community-Based Water Quality Monitoring in the Northwest Territories
Principal Investigator: Beveridge, Meghan
Licenced Year(s): 2018 2017 2016 2015 2014 2013
Summary: The purpose of the project is to work in collaboration with Northwest Territories (NWT) communities to collect water quality data to answer community concerns and questions about the health of NWT waters, to enhance understanding of cumulative impacts and to contribute to decision making. There are three associated objectives: 1) collect water quality data at locations throughout the NWT, to ...


The influence of forest fires on metal deposition to lakes and peatlands in the North Slave Region, NWT
Principal Investigator: Chetelat, John
Licenced Year(s): 2016
Summary: The research team will use natural environmental archives (lake sediment and peat cores) to characterize the forest fire history in the study region and test the relationship between fire events and metal accumulation over recent centuries. Study sites will be selected along a gradient of recent forest fire activity with some study sites located in areas of the latest burns (2014-15) to examine th...


Geoscience Tools for Supporting Environmental Risk Assessment of Metal Mining
Principal Investigator: Galloway, Jennifer
Licenced Year(s): 2016
Summary: This project will focus on providing baseline information for areas of high resource potential. In areas of past land use and soon to be developed areas in the Slave Geological Province, the project will generate new spatial and temporal data on changing geochemical, permafrost, ecological and climate data for the past 1000 years. This data will be integrated with Traditional Ecological Knowledge ...


Hydrothermal event recognition and vectoring to SEDEX ore system in shale basins, Yukon and NWT
Principal Investigator: Paradis, Suzanne
Licenced Year(s): 2013 2012 2011
Summary: The objectives of this research project are to identify some proximal (close) and distal (at a distance) mineralogical and chemical elements that will indicate that rocks in a sedimentary basin are likely or not to be rich in metals. To achieve the objectives, preliminary field work will continue during the summer months of July and August of 2013 and 2014. The field work consists of: - fam...


Northern Base and Precious Metal Potential, Victoria Island (NWT) and Nunavut
Principal Investigator: Bédard, Jean H
Licenced Year(s): 2011 2010
Summary: Northern residents and communities rely on the resource industry for employment and related economic benefits (e.g. Polaris Pb-Zn mine, diamond mines). The principal objective of this project is to improve our understanding of the geology of central Victoria Island (NWT). This will provide an improved understanding of the geology in two areas with base and precious metal potential, likely increas...


Geochemical and Mineralogical Controls on Metal Dispersal Downstream of Mineralization in the Mackenzie Mountains, Canada
Principal Investigator: Skeries, Kristina A
Licenced Year(s): 2011
Summary: The objective of this research project is to understand how metals might be weathering from rocks, and to understand where they end up and in which chemical form (the speciation). The importance is to differentiate between the metal species that weather from the rocks, the species by which they are transported, and finally, the species by which they are deposited again, if they are in fact deposit...


The role of aquatic and terrestrial vegetation in controlling the mobility of arsenic and other metals in northern environments
Principal Investigator: Stephen, Celsian C
Licenced Year(s): 2010
Summary: The objective of this project is to enhance our understanding of the controls on the mobility of metal contaminants in mine-impacted environments. More specifically, to enhance our understanding of the role terrestrial and aquatic plants play in sequestering mine-contaminants such as arsenic, antimony, copper, lead and zinc. The field methods for this program consist of a soil and vegetation...


Waste Rock Studies at a Diamond Mine Site
Principal Investigator: Blowes, David W.
Licenced Year(s): 2014 2013 2012 2011 2010 2009 2008 2005
Summary: In this project four test-scale piles will be studied, two composed of rock from the diamond mine site, and two composed of mine rock with reclaimation covers placed on the top. Under study are the hydrology of the piles, the release of metals by sulfide oxidation and the attenuation of these metals through the formation of secondary minerals. The concentrations of oxygen and carbon dioxide in the...


Bioavailability and toxicity of heavy metals in the Slave River Delta, NWT
Principal Investigator: Stone, Michael
Licenced Year(s): 2004
Summary: Currently, there is no information about the bioavailability and toxicity of metals in the Slave River delta. The goal of this research is to examine metal cycling pathways in the delta and to assess the role of aquatic vegetation for metal accumulation...


Resource Assessment of Intrusions in the Northern Cordillera: parts of NTS 1051, H, P, 95E,L
Principal Investigator: Falck, Hendrik
Licenced Year(s): 2003 2002
Summary: The purpose of this project is to develop and compile an inventory, and improve the understanding of mineral deposits related to granite intrusions in the western Northwest Territories. Understanding the concentrations of metals in the environment is im...
