This case study reviews a gas station site in Greenville, Alabama where petroleum hydrocarbon contamination was present in the subsurface for decades. PersulfOx, PlumeStop, and ORC Advanced were applied to quickly reduce benzene levels to non-detect, resulting in successful regulatory closure. This site is part of an environmental liability transfer and Antea Group®, an international engineering and environmental consulting firm, assumed the liability for this site. Antea Group required an effective remedial solution that would result in rapid site closure. Antea Group partnered with REGENESIS® to create a remedial design using an in situ chemical oxidation (ISCO) treatment paired with an aerobic bioremediation technology to ensure a complete treatment of this site.

Case study highlights:

  • Exceptional benzene reduction using PersfulOx quickly reduced contaminant levels within a short timeframe.
  • Design Verification Testing (DVT) fine-tuned the application to increase effectiveness.
  • Addition of PlumeStop application ensured against back diffusion to help reach site closure.
