Novel Aspects of the Remediation of PCB-Contaminated Soils in the Canadian Arctic: Excavation and PRB Technology

摘要

Resolution Island, Nunavut, just southeast of Baffin Island, is part of a North American military defense system established in the 1950s and became heavily contaminated with PCBs during its operational years, Remediation of this soil will be completed by the end of 2005. The scale of contamination coupled with fractured bedrock, topography, extreme weather conditions and remoteness of the site heighten trie challenges of an effective remediation. Remediation through excavation of the fCB contaminated soil at Resolution Island began in 1999 and at its completion almost 5 tonnes of pure PCBs in approximately 25, 000 m3 of soil will have been remediated.
