Synergistic in situ technologies treat TCE during construction works

Case study highlights

  • 40% reduction in TCE concentrations within 15 weeks of treatment
  • Enabled redevelopment and real estate transactions without delaying construction
  • Prevented offsite plume migration with a 100-meter reactive barrier

A former industrial redevelopment site in Liverpool, UK, required remediation of a large trichloroethene (TCE) groundwater plume while construction activities remained underway. REGENESIS implemented a synergistic in situ treatment strategy on behalf of Curtins, combining S-MicroZVI®, 3-D Microemulsion® (3DME), and Bio-Dechlor Inoculum Plus® (BDI+) to address contamination at the source and along the site boundary. The approach reduced TCE concentrations, mitigated offsite migration, supported regulatory closure requirements, and allowed redevelopment to proceed on schedule without the need for long-term above-ground treatment systems.
