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

Background

Beginning in 1918, the chemical facility quickly grew, employing around 20,000 people in its heyday. When the plant eventually closed in 2012, legacy contamination remained in the soil and groundwater. This included chlorinated solvents – predominantly TCE, resulting from bulk storage leaks and drainage – as well as petroleum hydrocarbons and asbestos. Remediation was required to reduce contaminant mass and mitigate the risk of off-site migration of the chlorinated solvent contamination.

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.
