TERRE-NET: Controls on the Release of Contaminants from Gold Tailings at the Giant Mine, Yellowknife, NT
chercheur principal: Blowes, David W.
Année(s) de permis: 2024 2023 2022 2021 2020 2019 2018 2017
Résumé: This licence has been issued for the scientific research application No.5447. The objectives of this project are to: 1) determine the magnitude and rate of release of arsenic and other toxic elements from the Giant Mine tailings to groundwater; 2) evaluate remediation alternatives for tailings management, including the effects of proposed engineered covers; and, 3) apply novel characterization ...


Recovery of the Mine-impacted Landscape in the Yellowknife Region
chercheur principal: Palmer, Mike
Année(s) de permis: 2023
Résumé: 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...


A multidisciplinary investigation of recovery in Yellowknife area lakes from 50 years of arsenic pollution: What are the factors inhibiting recovery and the biological consequences?
chercheur principal: Palmer, Mike
Année(s) de permis: 2019 2018 2017
Résumé: The overarching objectives of this research are two-fold: 1)To investigate watershed and within-lake abiotic processes affecting the recovery of mine-impacted lakes in the Yellowknife area, including storage and release of arsenic from soils, seasonal dynamics of arsenic export in runoff, and fluxes of arsenic to and from lake sediments; and 2) To investigate the toxicological consequences of ...


Legacy arsenic pollution in Yellowknife Bay sediments: An assessment of its long-term fate under a changing climate
chercheur principal: Chételat, John
Année(s) de permis: 2019 2018
Résumé: 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...


Developing New Tools for Assessing Legacy Pollutants and their Ecological Consequences in Lakes Near Northwest Territories Mines
chercheur principal: Blais, Jules M
Année(s) de permis: 2017 2016 2015
Résumé: 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...
