Closeup of Resolution Island and neighbouring area
'Resolution Island' is one of the
Canadian arctic islands in
Nunavut,
Canada. It is located off the eastern tip of
Baffin Island at 61°30'N 65°00'W with an area of 1,015 square kilometers.
English explorer
Martin Frobisher landed on the island on July 28, 1576, while on a voyage to discover the fabled
Northwest Passage.
The island was home to an American military base that became operational in 1954 as part of the
Distant Early Warning (DEW) line. The base was vacated in 1973 and turned over to the Canadian government in 1974.
It was during site investigations between 1987 and 1990 that contamination at the site was first discovered. The contamination originates largely from spills from the radar equipment, which used
polychlorinated biphenyls (PCBs) as insulators. Other pollutants include unused transformer fluids,
hydrocarbons,
asbestos and
heavy metals in the buildings and sprinkled throughout the site. Resolution Island has been identified as having the highest level of PCB contamination of all former military sites that fall under
Indian and Northern Affairs Canada’s (INAC) responsibility in the North.
In 1993 and 1994 an environmental site assessment of the area was completed. As a result, temporary barriers were placed across drainage paths to stop the migration of PCBs into the water. Further investigations were done and, in 1997, INAC initiated remediation work with Qikiqtaaluk Corporation (QC). A large-scale remediation plan was developed, in cooperation with
Environment Canada, QC and
Queen’s University. Steps were taken at that time to ensure that the contaminants were not posing a risk to humans and wildlife.
