Summary: The objective is to use academic and non-academic media to examine and communicate community perspectives on the history, and current problem, of arsenic deposition in Yellowknife. The research team will not only ask how these historical memories have influenced the current controversy over the Giant Mine Remediation Project, but will also examine the challenges of communicating the extreme hazard...

Summary: The specific objectives of this research are: 1) to investigate concentrations of arsenic and other elements in regional soils to gain a better understanding of regional baseline soil geochemistry; 2) to determine speciation of arsenic in selected soils from the region with elevated concentrations to determine whether arsenic in soils is from a natural geologic source or is derived from past indus...

Summary: The primary objective of this research program is to determine the environmental and physical conditions of nine sites in the Gordon Lake region. This research will include the identification and quantification of environmental impacts in soil, sediment, surface water and groundwater. Samples of biota (e.g. Hyalella) may be collected at certain sites during the field program. The potential for...

Summary: The primary objective of this research is to analyze near-surface tailings from the tailings ponds and shoreline at Giant Mine in Yellowknife, Northwest Territories, and to distinguish the arsenic-hosting phases in both the bulk tailings and the fine fraction of the tailings from the site. The research team will initially take near-surface samples of tailings - from which windblown dust may be ...

Summary: The purpose of this study is to determine whether the arsenic present in regional lake sediments is of natural or anthropogenic origin, and whether these lakes act as a sink (capture) or a source (release) of arsenic in the overlying lake waters. By evaluating the relative stability of arsenic species in these different chemical media, the research team may establish the long term trends of arseni...

Summary: The objectives of this research are to evaluate the relative sensitivity of northern aquatic invertebrates and northern ecosystems in comparison to southern species and environments. The focus of comparisons is in relation to the toxicity of rare earth elements. Three types of sample collections are proposed. These would be done at the Avalon Rare Metals Inc. Thor Lake site as well as along t...

Summary: The objectives of this research project are: 1) to determine the impact of shoreline expansion and forest/peat submergence from thawing permafrost on contaminant and carbon fluxes to lakes in the Yellowknife region; 2) to develop novel approaches to track terrestrial organic matter sources in lakes, in order to assess how climate warming and permafrost thaw are affecting the delivery of terrestr...

Summary: This research study is designed to investigate the processes related to water quality and quantity (collected at different scales) draining from country rock stockpiles that are located in areas of continuous permafrost. The quality of water draining from a country rock stockpile is determined by the combined effects of oxygen transport in the air phase, biogeochemical processes that control miner...

Summary: The objectives of this project are to draw together multiple sources of information so that the research team may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and int...

Summary: The objectives of this research is to: determine total arsenic and arsenic species in edible and non-edible mushrooms from contaminated and uncontaminated locations (mine properties and roadsides/parks); determine total arsenic and arsenic species in plants including Labrador tea, horsetails, buffaloberry, fireweed and berries (if available) from contaminated and uncontaminated locations (mine pro...
