Rapid Elimination of Chlorinated Solvents

Case Study Highlights:

• Combined approach using 3 REGENESIS remediation products resulted in >99% reduction in CVOC concentrations

• 90% reduction goal achieved within 4 months post-application

• Ongoing monitoring indicates the continued effectiveness of the treatment, with additional reductions expected in the following months

In Southern California, a retail facility with an active food service tenant faced significant groundwater contamination from chlorinated solvents, primarily tetrachloroethylene (PCE) and trichloroethylene (TCE), resulting from a historical release at a former dry cleaners on-site, which also impacted adjacent properties. Despite previous remediation efforts, high contaminant concentrations persisted, feeding a contaminant plume. Using 3-D Microemulsion^® (3DME), our sulfidated micron-Scale ZVI : S-MicroZVI^® , and Bio Dechlor Inoculum Plus^® (BDI Plus), the site achieved a greater than 99% reduction in CVOC concentrations and halted plume migration through biologically enhanced reductive dechlorination (ERD) and in situ chemical reduction (ISCR), meeting the site’s performance goals.
