Fuel Spill Remediation (CAN)
SLR was retained to manage the investigation and in-situ remediation of a former helicopter base near Nelson, BC. A spill of jet B fuel was identified from an underground storage tank in 1995, and SLR provided subsequent site assessment and remediation services to remediate the site. In 2004, SLR applied for an Approval in Principle with the BC Ministry of Environment, and initiated the remediation phases of work.
The complex site history included former use of the land for a municipal landfill, and adjacent historical rail operations. SLR installed an in-situ air sparging trench to act as a cut-off wall presenting dissolved phase contamination from entering the lake.
