IES Webinar: Successful biostimulation and bioaugmentation treatment of DNAPL

First broadcast: 12 August 2019 by IES

In this webinar, Jack Shore, District Manager of UK and Scandinavia at Regenesis, explores the complexities of a case study at an industrial site in Scotland. High concentrations, including DNAPL, of mixed chlorinated solvents, TCA and TCE, were present in the groundwater under an active industrial site in Scotland. A DPVE system had been unable to achieve the remediation goal of a 75% reduction in chlorinated solvent mass. Also a supplementary MIP investigation showed that there was further contamination deeper than the maximum treatment depth of the DPVE system ~ 6mBGL. Therefore it was determined that an alternative remediation method was required.
