In Situ Chlorinated Solvent Treatment Protects Municipal Pumping Station

Remediation of a former dry cleaner site in Värnamo, Sweden

In situ remediation of groundwater impacted with high levels Tetrachloroethene (PCE) was completed at a former dry cleaning site, as the temporary installed groundwater recirculation system proved too expensive to run as a permanent solution. RGS Nordic carried out soil remediation using muliphase extraction and worked with REGENESIS to provide a remediation solution for the groundwater plume. Read the case study to find out about the remedial design, application and the results.

Highlights

• Example of a sustainable solution as no further operation cost or energy use required and it produced no waste for disposal
• Enhanced Reductive Dechlorination using a mix of REGENESIS electron donors delivers reduction in total chlorinated solvents of 99.6%
• 8 years of monitoring data shows no rebound in parent or daughter contaminant concentrations
• Downstream municipal pumping station is now protected from further contaminant ingress without the need for a protective pump & treat system
