Treatment of PCE ContaminationThis case study reviews a multi-tenant commercial plaza in the greater Boston area that required remediation of tetrachloroethylene (PCE) contamination in groundwater where a combined remedy approach used at delivered accelerated results using PlumeStop®, BDI Plus® and HRC®.

Due to the owner’s objective to sell their property, a multi-tenant commercial plaza in the greater Boston area required remediation of tetrachloroethylene (PCE) contamination in groundwater associated with historical operations. Because contamination had been identified during due diligence, it was very important to implement a time-effective remediation strategy with minimal disruption to the various operating businesses. Wilcox & Barton, Inc. chose a combined remedial approach to treat the PCE contamination. This included liquid activated carbon (PlumeStop), an enriched, microbial consortium (BDI Plus), and an engineered, hydrogen release compound (HRC).

This case study highlights:

  • Due to the high-traffic and operational hours at this site, injections were performed from 10pm-7am in January.
  • The speed in which Wilcox & Barton, Inc. addressed the contaminants was crucial for the site owners to achieve their goal of marketing the property for sale.
  • Site engineers innovatively included heating systems, additional lighting, and warming facilities to ensure that the remedial agents stayed in their liquid form and to provide necessary amenities to the injection specialists.
  • The combined remedy approach of PlumeStop, BDI Plus, and HRC was selected amongst other remediation strategies for its fast-acting capabilities and its effectiveness in completely dechlorinating contaminants.
