This case study reviews the successful in-situ treatment of chlorinated solvents at a former food processing plant located in a suburb south of Indianapolis. PlumeStop, S-MicroZVI, 3DME and BDI Plus were used in combination to strongly inhibit CVOC plume migration near the site property boundary while enhancing abiotic and biotic degradation of CVOCs at this location and in the upgradient plume area.
Case study highlights:
- Innovative combined remedy on active site effectively eliminates risk to adjacent property
- Remedy from REGENESIS chosen based on proven effectiveness in treating similar large CVOC plumes
- Design Verification Testing and placement validation guide a successful remedial application
Patriot Engineering and Environmental, Inc. (Patriot), a leading consulting firm based in Indianapolis, investigated the site, discovering contaminants had migrated from an unidentified source and formed a large plume. In addition, it was found that the plume was being pulled toward a former (now inactive) public water supply well. The primary chlorinated volatile organic compounds (CVOCs) detected in the plume were tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (cis-DCE).
