    Site Goals Met Within 60 Days

    Case study highlights:

    This case study reviews the confidential site of a large-scale in situ groundwater treatment of trichloroethene (TCE) at a former industrial manufacturing facility with challenging project objectives and an agressive remediation timeline.

    • TCE eliminated within 60 days post-application

    • This reduction has been continuously maintained more than 5 years to date.

    • The highly controlled PlumeStop injection resulted in no ‘day lighting’ or ‘surfacing’ inside the building.

    A collaborative remedial design and strategic implementation effort between REGENESIS and the consulting firm resulted in the project’s success. This collaboration led to a dynamic remediation application strategy entailing planned, in-field adjustment to the design based on information obtained and assessed during remediation. An innovative remediation approach was needed to meet a very stringent deadline for the work’s completion. Through careful planning and scheduling, RRS met the implementation deadline, which included work inside an active warehouse and retail business.

    TCE and low concentrations of other chlorinated volatile organic compounds (CVOCs), cis-1,2-dichloroethene, vinyl chloride, and 1,1,1-trichloroethane, were treated using an innovative sorption-enhanced reductive dechlorination (ERD) approach that virtually eliminated groundwater contaminants within 60 days of application. The permeable reactive barrier (PRB) installed at the site property boundary has eliminated TCE for over five years, meeting the application’s performance objectives by cutting off the site’s contribution to a more extensive groundwater TCE plume.
