  2. PHC & Heavy Metal Remediation In Northern British Comumbia
Brief

A former refueling station for highway maintenance vehicles was found to have soil and groundwater impacted with petroleum hydrocarbons and heavy metals. This site was located in a remote area of Northern British Columbia, along the Alaskan Highway. The plume on this site was shown to be spread over a large area and was found down to 12.5m below ground surface levels.

An environmental consulting firm characterized the site and recommended an integrated approach to remediating the soil and groundwater.

Process

IRSL worked alongside a general contractor to implement an integrated remediation approach. This included an ex-situ component, which involved the excavation and removal of contaminated soil and an in-situ component that utilized Direct Push Technology (DPT) injections to deliver hydrogen peroxide to the impacted groundwater and soil. IRSL completed the in-situ component of the project.

The large-scale plume necessitated the design of an injection system that could inject very large volumes of solution while ensuring the reagents injected in each DPT point accurately reflected the remediation plan. With the newly designed system IRSL was able to inject to to 110,000 litres of solution per day.

Results

There was an overall average reduction of 47% in F2 petroleum hydrocarbons in the soil being treated in-situ.

This complex remediation program was completed on time and on budget.
