High Levels of TCE Remediated at Former Chemical Manufacturing Facility, UK

Case study highlights:

• Combined ERD/ISCR treatment has achieved the site’s remedial objectives rapidly and cost-effectively, allowing the site redevelopment to continue
• Lines of evidence suggested high rates of dechlorination continued to occur and that full destruction of the contamination was being achieved
• The in situ application continues to effectively degrade the chlorinated solvent contaminants, reducing the contamination concentrations, overall plume footprint, and exposure risk
• The treatment serves as a model for an effective plume management strategy for large-scale, high-concentration chlorinated solvent sites, including those with significant DNAPL mass

With many site investigations and remediation attempts made over >30 years by other consultants and contractors, Vertase FLI was appointed to undertake the design, management and ultimate sign off of the remediation, which included ex situ bioremediation, asbestros management and a complex upfront site investigation and verification exercise. Vertase employed REGENESIS to remediate a portion of the site where the groundwater was found to be highly contaminated with TCE and lesser concentrations of cis-1,2 DCE. REGENESIS provided an in situ treatment strategy and turnkey solution for the chlorinated solvent source area.
