Complimentary Roux Webinar: A Blended Approach for Remediating Chlorinated Solvents in Groundwater

A Blended Approach for Remediating Chlorinated Solvents in Groundwater

Tuesday, October 30th • 1pm EST • Presented by Tim Adams, P.G.,
Principal Hydrogeologist

Chlorinated volatile organic compounds (CVOCs), mainly 1,1,2 trichloroethane (TCA) and 1,1 dichloroethene (DCE) and their associated breakdown products, were present in soil and groundwater because of the historical operation of a process water holding pond at an active industrial facility located in southeastern Kansas. Industrial operations had been conducted at the Site since 1963. Spent cleaning liquids were discharged to a 5-pond recirculating system equipped with an oil recovery unit. The pond system was closed and decommissioned in 1987. A remediation plan was developed to implement source area soil and groundwater treatment using soil blending and direct injection techniques for delivery of remediation amendments.

Full-scale remediation was completed in Spring 2015. Post-remediation performance monitoring was initiated November 2015 on a semi-annual basis. Temporal trends for CVOCs and geochemical parameters in the blended and direct injection treatment areas indicate greater than (>) 85% to >99.9% contaminant decreases, and optimal reducing groundwater geochemistry.

Tim Adams has over twenty-eight years of experience in environmental consulting services. This webinar will discuss the case study above as well as the best practices or approaches for remediating chlorinated solvents in groundwater.
