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): 2017
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...

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 ...

Principal Investigator: Blais, Jules M
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...

Principal Investigator: Galloway, Jennifer
Licensed 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 ...

Principal Investigator: Stephen, Celsian C
Licensed 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...

Principal Investigator: Blais, Jules M
Licensed Year(s): 2010
Summary: This research goal is to examine the role of thermokarst development on natural organic matter and the release of metals (e.g. mercury) and organic contaminants (e.g. polychlorinated biphenyls - PCBs). Sampling for contaminants: Water sampling for persistent organic pollutants (POPs) will be done by passive samplers, consisting of a semi-permeable membrane containing a resin that will extract ...

Principal Investigator: McGurk, Michael
Licensed Year(s): 2005 2004
Summary: The researchers will measure water quality, aquatic ecology and the status of fish populations in ponds and lakes along the proposed discharge route of mine water from the Colomac Mine (North Pond, L-Shaped Lake, Paddle Lake, Lake 315, and Lower Lake) and compare those data with data collected from reference lakes (Steeves Lake, Baton Lake, and Spanner Lake). Work will include taking three samples...

Principal Investigator: Moore, Peter
Licensed Year(s): 2003
Summary: As part of the 2003 Baker Creek Environmental Monitoring Program, Dillon Consulting Limited will conduct fish habitat assessments at Baker Creek, Yellowknife. Benthic invertebrates will be sampled at each of 8 sampling sites using multi-plate artificial...
