  • Direct-Push Injection and Circulation Biobarrier to Remediate a TCE Groundwater Plume

    ABSTRACT: The goal of this study was to determine if direct-push drilling methods combined with a circulation system could be used to establish a passive biobarrier in a very transmissive aquifer to treat tricholoroethene (TCE). The Site is located in central Indiana, where historic use of TCE has impacted an unconfined aquifer. A plume consisting primarily of TCE has migrated from west to east ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • TCE/Fractured Bedrock Remediation in VA

    Site Summary At a manufacturing facility HRC was injected into a crystalline bedrock aquifer contaminated with TCE and its daughter products. Groundwater flow at this site is controlled by fractures in the crystalline rock with little or no permeability present beyond these fractures. The industrial facility had been in operation for over 30 years. Contamination levels reached 220 ppb of TCE so ...

  • Chloroflourocarbon (CFC) remediation case study

    Project Description The Site location was an industrial facility located in the greater South Los Angeles region that manufactured chemicals for local petrochemical and other industrial operations from 1919 through late 1990’s. Refrigerants were initially produced in 1964 including chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs) such as trichlorofluoromethane (R-11), ...

  • Combining HVME and Enhanced Bioremdiation for Gasoline Contamination in Groundwater.

    ABSTRACT A leaking underground storage tank at a commercial petroleum retail site located in Haskell, Texas resulted in soil and groundwater petroleum hydrocarbon contamination. This contamination, including benzene, toluene, ethylbenzene, and total xylenes (BTEX) and total petroleum hydrocarbons (TPH) migrated down-gradient below a road and neighboring property. Access below the adjacent roadway ...

  • Spolchemie site remediation and NanoRem field site application

    Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the ...

  • Case study - World`s largest remediation site

    Overview Hong Kong's Kai Tak Airport, the world's busiest airport in 1997, became the world's largest remediation site once it was closed. When the airport was decommissioned in 1999 in favor of the new Chek Lap Kok Airport, the government planned to rapidly clean up the site for commercial and residential development. After many years of soil penetration by various ...
