  • Peroxygen Mediated Bioremediation of MTBE.

    ABSTRACT: Evidence is mounting, from laboratory and field studies, that oxygen plays a role in the bioremediation of methyl tertiary butyl ether (MTBE). Our experience with a number of commercial applications of peroxygen, in the form of Oxygen Release Compound (ORCâ), correlates the provision of enhanced aerobic conditions with enhanced MTBE biodegradation. Subsequent laboratory and field ...

  • Soil and Groundwater Treatment of MTBE

    Project: Treated 4,200 cubic yards of petroleum contaminated sandy-silty soil and waterClient: Speedy Express Service Station Location: Walterboro, South Carolina Scope of work: In-Situ Bioremediation Project cost: $30,000 (Included only microbial products) Source of ...

  • MTBE Groundwater BioTreatability Study

    The following graph illustrates the analytical results of a bio-treatability study conducted on MTBE. A two-liter groundwater sample was collected from the client's service station in western Pennsylvania. We tested three different combinations of microbe and nutrient products in order to determine which products are the most effective. The results indicate that MTBE can be bioremediated by our ...

  • Pilot Scale Application of ORC Advanced Reduces TPH and MTBE

    Site Summary ORC Advanced releases a maximum of 17% by weight of oxygen into a saturated area. Such a high release of oxygen can effectively reduce high concentrations of contaminants, allowing for successful bioremediation of source areas. A petroleum contaminated site in Virginia had TPH and MTBE contamination at levels much higher than MCLs. The source area contained concentrations of TPH and ...

  • Biodegradation of MTBE Utilizing A Magnesium Peroxide Compound: A Case Study.

    ABSTRACT: A patented magnesium peroxide compound was recently employed at an underground storage tank facility to increase the available oxygen in the groundwater for the biodegradation of fuel hydrocarbons. The objective of this remedial effort was to substantially reduce the dissolved-phase concentrations of BTEX and MTBE and to arrest further migration of the dissolved fuel hydrocarbon plume. ...

  • Accelerated Petrox® Bioremediation of Naphthalene and Methylnaphthalene Isomers

    Petrox bioaugmentation was implemented at a former gas station UST removal site in Miami, Florida to destroy residual petroleum compounds in ground water.  The UST and contaminated soil were removed.  The residual ground water contamiantion, however, persisted and Petrox bioremediation was implemented to remove the residual low concentrations of MTBE, BTEX, naphthalene and ...

  • 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 ...


  • Site Closure Sought after using ORC® Biobarrier to Enhance Aerobic Biodegradation of MTBE and TPHg

    CASE SUMMARY Former Service Station - Bishop, CA Extensive methyl tertiary-butyl ether (MTBE) and total petroleum hydrocarbons as gasoline (TPHg) contamination was discovered within the subsurface as a result of leaking underground storage tanks (USTs) at a former service station. Following the removal of the leaking USTs, a total of 1,192 cubic yards of gasolineimpacted ...

  • Surfactant desorption is key to successful PAH bioremediation

    Formulations which are patented non-ionic surfactant mixtures used in the in situ and ex situ treatment of petroleum hydrocarbons, chlorinated solvents, heavy metals, and more recently PAHs, PCBs and MTBE type contaminated waste are involved in Surfactant Enhanced Bioremediation (SEB®) using Iveysol ®. These surfactant formulations have the ability to enhance soil biodegradation. During in ...

  • 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 ...
