Principal Investigator: Devoie, Élise
Licensed Year(s): 2024
Summary: This licence has been issued for the scientific research application No. 5898. The main goal of this project is to explore how wildfire will affect the stability and fate of metals and metalloids (i.e. arsenic, mercury, antimony) in mining contaminated and pristine landscapes. Metal(loid) concentrations in air, soil, and water in and around Boundary Creek (30 km west of Yellowknife) will be co...

Principal Investigator: Palmer, Mike
Licensed Year(s): 2023
Summary: This licence has been issued for the scientific research application No.5534. The long-term objective of this research is to determine what processes control the recovery of the landscape near Yellowknife that was contaminated by stack emissions from the Giant Mine roaster, and how this recovery will be affected by climate change and unusual or severe weather events. One focus will be on how cl...

Principal Investigator: Amuno, Solomon A
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...

Principal Investigator: Bromstad, Mackenzie J
Licensed Year(s): 2010
Summary: The objective of this project is to understand why arsenic trioxide (As3+) is still present in soils around Giant Mine, how long it will remain there, and if the set of circumstances leading to persistent As3+-rich soil may apply to any other places previously assumed to be As3+-free. In terms of current mine remediation, future human contact with the site, and ecosystem health, it needs to be und...

Principal Investigator: Fawcett, Skya
Licensed Year(s): 2007 2006 2005
Summary: The purpose of this project is to study the mobility, speciation, and mineralogical and geochemical controls on antimony (Sb) and arsenic (As) originating from the Giant Mine. This research could aid in designing reclamation plans, resolving the relation between Sb and benthic diversity and identifying threats to the Great Slave Lake ecosystem. Understanding the movement and speciation of As and S...

Principal Investigator: Caughill, Dave
Licensed Year(s): 2004
Summary: Between 1948 and 1951, approximately 375 000 tons of tailings were deposited directly into Back Bay from Giant Mine along the northwest shore via a drainage channel. The submerged tailings contain high levels of metals, particularly arsenic. Over time, t...

Principal Investigator: de Rosemond, Simone
Licensed Year(s): 2003
Summary: The Giant Mine, Yellowknife, was in operation for more than 50 years during which time arsenic levels in the surrounding area have significantly increased due to the roasting methods used to extract gold from mined ore. Arsenic was measured in walleye (...

Principal Investigator: d'Entremont, Marc
Licensed Year(s): 2003
Summary: In preparation of DIAND's detailed Arsenic Trioxide Management Project Description, an assessment of the current environmental conditions at and around the Giant Mine site and an assessment of the potential environmental impacts associated with implement...

Principal Investigator: Andrade, Claudio
Licensed Year(s): 2003
Summary: The overall goal is to provide data on arsenic cycling in sub-aqueous sediments to better understand the potential environmental impacts within Yellowknife Bay and the long-term fate of arsenic. Important objectives of the project are to assess the stab...

Principal Investigator: Wong, Stephen
Licensed Year(s): 2001
Summary: The research team will examine soils which will be collected by DIAND Contaminants Division staff from Yellowknife. Approximately 20 kg of contaminated soil will be collected from a site close to the Con Mine. As well, approximately 80 kg of uncontaminated soil (for use as a reference soil) will be collected from a site adjacent to the Rae Highway. All soils will be returned to a laboratory at ...
