  • Emulsified-Oil Biobarrier Provides Long-Term Treatment of Perchlorate/VOC Plume

    Security Technology Certification Program (ESTCP) evaluation of a PRB containing emulsified oil substrate (EOS®). The pilot study was initiated in 2003 at the Alliant Techsystems, Inc., facility in Elkton, MD, to evaluate effectiveness of EOS technology for enhancing biodegration of perchlorate and chlorinated solvents. A single dose of low solubility, low viscosity, and slowly biodegradable ...

  • Perchlorate Remediation Project Case Study

    ARCADIS was contracted in 2000 to lead the development, evaluation and selection of a final groundwater remedy for this 94-acre site in California. As part of this work, ARCADIS is also participating in the evaluation of innovative technologies with the potential to treat soil impacts in the multiple source areas across the site. Specifically, the project is focused on the remediation of seven ...

  • In-Situ Anaerobic Remediation of Perchlorate-Impacted Soils

    AbstractARCADIS is currently leading the development, evaluation, and selection of a final groundwater remedy for a 94-acre manufacturing facility in the western U.S. This facility has produced small explosives and vehicular safety products since 1957. As a result of historic operations, soil and groundwater at the site have been impacted by perchlorate. To date, remediation efforts have been ...

  • In Situ Remediation of Perchlorate in Soil and Groundwater, M.S. Thesis, California State University San Bernardino

    This research project documents a technology assessment for in-situ bioremediation of perchlorate (ClO4-). The main goals are to compare methodologies, perform site characterization of soil and groundwater, and perform microcosm and bench scale tests. In this approach, perchlorate is reduced to chloride, requiring an electron donor. The suitability of electron donor amendments will be assessed ...

  • Concurrent bioremediation of perchlorate and 1,1,1-trichloroethane in an emulsified oil barrier

    Abstract A detailed field pilot test was conducted to evaluate the use of edible oil emulsions for enhanced in situ biodegradation of perchlorate and chlorinated solvents in groundwater. Edible oil substrate (EOS®) was injected into a line of ten direct push injection wells over a 2-day period to form a 15-m-long biologically active permeable reactive barrier (bio-barrier). Field ...

  • The In Situ Bioremediation/Groundwater Remediation Process

    In-situ groundwater bioremediation is a technology that encourages growth and reproduction of indigenous microorganisms to enhance biodegradation of organic constituents in the saturated zone. In-situ groundwater bioremediation can effectively degrade organic constituents which are dissolved in groundwater and adsorbed onto the aquifer matrix. The Adventus In Situ Bioremediation/Groundwater ...


  • Enhanced Anaerobic Bioremediation of a TCE Source Area at the Tarheel Army Missile Plant using EOS®

    Emulsified oil substrate (EOS®) is being used to remediate a trichloroethene (TCE) source area at the Tarheel Army Missile Plant (TAMP) in Burlington, North Carolina. 1. INTRODUCTIONEmulsified oil substrate (EOS®) is being used to remediate a trichloroethene (TCE) source area at the Tarheel Army Missile Plant (TAMP) in Burlington, North Carolina. TAMP is a government-owned, formerly ...

  • DOD Compares Benefits of Active and Semi-Passive Biobarriers

    Current ESTCP demonstrations are examining design, construction, and performance elements of a semi-passive barrier at the Longhorn Army Ammunition Plant (AAP) in Karnack, TX, and those of an active barrier at the Navy Industrial Reserve Ordnance Plant (NIROP) in West Valley City, UT. DOD’s upcoming guidance manual for characterizing and remediating perchlorate-contaminated ground water will ...

  • Enhanced Anaerobic Bioremediation of a TCE Source at the Tarheel Army Missile Plant Using EOS

    EOS, or emulsified oil substrate, was used to stimulate anaerobic biodegradation of trichloroethene (TCE) and tetrachloroethene (PCE) at a former Army-owned manufacturing facility located in the Piedmont area of North Carolina. Previous use of chlorinated solvents at the facility resulted in soil and groundwater impacts. Ten years of active remediation utilizing soil vacuum extraction and air ...

  • The Bioremediation Process

    Bioremediation allows natural processes to clean up harmful chemicals in the environment. Microscopic 'bugs' or microbes that live in soil and groundwater like to eat certain harmful chemicals, such as those found in gasoline and oil spills. When microbes completely digest these chemicals, they change them into water and harmless gases such as carbon dioxide. In order for microbes to clean up ...
