GMOB: Remediation Strategies for the Long-term Management of Arsenic-trioxide-bearing Roaster Wastes at the Giant Mine, Northwest Territories
Principal Investigator: Blowes, David W.
Licensed Year(s): 2024 2023 2022 2021
Summary: This licence has been issued for the scientific research application No. 5779. The overall goals of the four projects proposed within Phase 1 are to: 1. Provide an enhanced understanding of the physical and geochemical properties of the roaster waste 2. Screen for potentially viable remediation alternatives that may warrant additional research (e.g., long-term laboratory experiments, pilot-s...

Arsenic speciation in Yellowknife Lakes during spring bloom
Principal Investigator: Reimer, Kenneth J.
Licensed Year(s): 2010
Summary: The objectives of this research are to: 1. Determine total arsenic and arsenic species in water from Kam Lake and Meg Lake, 2. Determine total arsenic and arsenic species in porewater (which is a link between sediments and overlying water) from Kam Lake and Meg Lake, 3. Determine plankton communities, and total arsenic and arsenic species in plankton fractions, 4. Determine arsenic in food sou...

The presence and persistence of arsenic trioxide in soils around Giant Mine, NWT
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...

Speciation of Arsenic in Yellowknife, NT Soils
Principal Investigator: Wrye, Lori A
Licensed Year(s): 2007
Summary: The aim of this research project is to examine the speciation of arsenic in soils around the Giant Mine, and to distinguish if the arsenic is of natural or anthropogenic sources. Soils in the study area are naturally enriched in arsenic as well as from the mining of gold. The results will help understand how much of the arsenic is the result of human impact, how bioavailable it is, and how it move...

The Potential for Geochemical and Microbial Remobilization of Arsenic from Sediments in Yellowknife Bay, Great Slave Lake
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...
