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...

Investigation of the Extent of Historic Tailings in Back Bay/Yellowknife Bay
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...
