Combined Remedy Rapidly Achieves Targets to Address Chlorinated Solvent Impacts

Case study highlights:

• A multi‑faceted remedial solution mitigates CVOC contamination beneath an active business
• Successful application overcomes challenging site conditions
• Use of advanced colloidal remediation technologies from REGENESIS accelerates site toward closure with Regional Water Quality Control Board (RWQCB)

This case study reviews an active industrial facility in Southern California where PlumeStop and S-MicroZVI successfully treated CVOC contamination. The combined remedy quickly reduced CVOC concentrations below targets, priming the site for future regulatory closure. The responsible party retained Roux, a leading environmental remediation consultant, to complete the remediation project. Specifically, the remedy needed to (1) reduce CVOCs in soil, soil vapor, and groundwater to background contamination levels; (2) minimize disruption to the site tenant occupying the building; (3) coordinate with offsite property owners to complete the work; and (4) complete all work within established budgets and timeframes.
