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...

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...

Summary: The objective of the study is to: determine the spatial extent of sediments enriched by tailings solids; characterize the physical and geochemical characteristics of contaminated sediments in Baker Creek; determine to what extent arsenic and other elements of concern in these materials can be remobilized into the water column. Given the shallow water depth in Baker Creek, the majority of sedime...

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...

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 (...

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...

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...

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 ...
