  • Enhanced Bioremediation

    Introduction Enhanced bioremediation is a process in which indigenous or inoculated micro-organisms (e.g., fungi, bacteria, and other microbes) degrade (metabolize) organic contaminants found in soil and/or ground water, converting them to innocuous end products. Nutrients, oxygen, or other amendments may be used to enhance bioremediation and contaminant desorption from subsurface materials. ...

  • Petrox® bioremediation of trimethylbenzene isomers

    Remediation of trimethylbenzene isomers (TMB) is particularly challenging, but effective options including bioremediation are available. TMB is has characteristics similar to the BTEX compounds and some similar to middle range fractions such as naphthalene. These characteristics are summarized in the following table. The solubility of TMB is much lower than BTEX compounds, but much higher than ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...

  • Bioremediation Removes Environmental Stigma for Resort

    Untitled Document Although environmental contamination is far from our minds when we think of Florida resort properties, leaking underground storage tanks can contaminate soil and ...

  • Nanobite bioremediates a Contaminated harbour - Case study

    When a hydrocarbon is spilled on water, it is very visible – floating on the surface, a blue green sheen clearly visible. When applied to an oil spill on water, Nanobite Liquid will not mix with the water and become diluted. Within a minute it attaches to the hydrocarbon, bonding with it and creating a matrix – an agglomerated gel- that remains on the surface and cannot sink, no ...

  • 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 ...

  • A Pilot Study Using HRCTM to Enhance Bioremediation of CAHs.

    ABSTRACT: The effect of Hydrogen Release Compound (HRCTM) in enhancing the anaerobic bioremediation of chlorinated aliphatic hydrocarbons (CAHs) was observed in a single well pilot study. HRC is a proprietary, environmentally safe, food quality, polylactate ester formulated for the slow release of lactic acid upon hydration. Microbes metabolize the lactic acid releases by HRC and produce ...

  • 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 ...

  • Combining HVME and Enhanced Bioremediation for Gasoline Contamination in Groundwater

    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 was ...

  • Microbe-assisted phytoremediation approach for ecological restoration of zinc mine spoil dump

    Mining is one of the sectors that impacts air, water and soil pollution. The various environmental problems that are associated with mining activities are deforestation, removal of fertile topsoil, unstable slopes prone to sliding and erosion, siltation of water bodies due to wash off of mineral overburden dumps, air pollution due to discharge of dust and noise pollution. The most effective means ...

  • The Use of Hydrogen Release Compound (HRC) for CAH Bioremediation.

    Hydrogen Release Compound (HRC™) is a simple, passive, low-cost and long-term option for the anaerobic bioremediation of chlorinated aliphatic hydrocarbons (CAHs) via a reductive dehalogenation pathway. Applications to other classes of chlorinated compounds that are anaerobically degradable by this mechanism are under investigation. HRC should be viewed as a tool for the enhancement of natural ...

  • Enhanced Aerobic Bioremediation of Petroleum UST Releases in Puerto Rico.

    Abstract: Releases of petroleum compounds from underground storage tanks (USTs) containing diesel fuel and gasoline are a serious and increasingly prevalent problem in Puerto Rico. Remediation of groundwater impacted by these releases utilizing common methodologies can be quite costly and require long periods of time to implement. Oxygen is often the limiting factor retarding optimal ...

  • In-situ Aerobic Bioremediation of Recalcitrant Organics: A Case Study Demonstrating Benefits and Potential Limitations

    Abstract A history of spills and/or releases at two adjacent dry cleaning facilties in the Houston, Texas area resulted in significant soil and shallow ground-water contamination. The soils at the adjacent properties (collectively called 'the Site') are relatively permeable allowing for rappid vertical migration at the source area(s) and lateral migration in the shallow ground water. The ...
