  • Accelerated Bioremediation as an Alternative to Conventional Remedial Technologies.

    ABSTRACT: Application of bioremediation as an alternative technology to expedite soil and ground-water remediation has been effective in reducing the concentration of hydrocarbons at an affordable cost. Bioremediation processes can be achieved by the addition of biological organisms into the soil and ground water which are contaminated and are microorganism deficient. The microorganism's ...

  • Bioremediation of soil

    In our experience, Bioremediation is best accomplished with Bio-augmentation, the addition of large numbers of selected micro-organisms grown in the production laboratory. In addition to bio-augmentation, several physical and chemical parameters must be controlled in order to obtain optimal growth and maximum degradation of soil contaminants. The major factors that are controlled during ...

  • Bioremediation of Kerosene and Diesel Fuel in soil case study

    The United States has a large hazardous waste problem that is threatening both human health and the environment. Current analysis of the nearly 1,200 National Priority List (NPL) sites reveals that about 80% of the sites are contaminated with organic compounds. Clean-up of hazardous waste sites, as a national priority has accelerated the development of bioremediation technologies. Environmental ...

  • Field Application of a Lactic Acid Ester for PCE Bioremediation.

    ABSTRACT: As part of a strategy to enhance reductive dechlorination with a timed release of hydrogen, an application of glycerol polylactate (GPL) was made to a dry cleaner site contaminated with perchloroethylene (PCE). GPL is one of several proprietary lactic acid esters sold commercially as Hydrogen Release Compound (HRCTM). When HRC contacts the saturated contaminated zone, the lactic acid ...

  • Bioremediation/natural attenuation continues after ISCO treatment

    Scientists and engineers from the private sector and EPA are evaluating the potential for in situ bioremediation and/or natural attenuation to successfully treat residual soil and ground-water contamination after source-area in situ chemical oxidation (ISCO) treatment. The studies were prompted by concerns that the two treatment technologies may be incompatible due to detrimental impacts on ...

  • A Systems` Approach to In Situ Bioremediation: Full-Scale Application (PDF)

    An 18-month, in-situ biological program, specifically aimed at accelerating the current attenuation process such that the owner can sell the property began May 5, 2000. The remedial approach has focused on population management, nutrient augmentation, terminal electron acceptor enhancement, and an efficient subsurface delivery of the enhancement liquids. Specifically, a novel delivery system, ...

  • Time-Release Electron Donor Technology: Results of Forty-Two Field Applications (PDF)

    Hydrogen Release Compound (HRC) is a food grade, polylactate ester that, upon being deposited into the aquifer, is slowly hydrolyzed to release lactic acid and other organic acid derivatives. The organic acids are fermented to hydrogen, which in turn donates electrons that drive reductive bioattenuation processes. HRC delivers electrons in a time-release fashion for about one year. The ...
