BOS 100® Injection Facilitates Time-Sensitive Real Estate Transaction at Canadian Industrial Property

Summary

Historic industrial activities resulted in two separate chlorinated volatile organic compound (CVOCs) plumes in the groundwater at the site. An upcoming property transaction (in <6 months) required treatment of the groundwater impacts to meet stringent Ministry standards.

Approach

•Trap and Treat® BOS 100® was selected due to the short time frame (<6 months) and stringent Ministry standards.
•Acquired all relevant permits to complete the in-situ remediation program.
•Injected 5,400 lbs of BOS 100® into a grid of 135 temporary points over 14 days on site.
•Field schedule spread out the injection over 2 months to allow for consultant interim sampling.
•Adjusted injection program based on pilot test results and interim sampling results

Results

•Site remediation completed on time.
•All CVOCs impacts treated to Ministry standards
•Real estate transaction successful
