  • Improving bioremediation

    Sustainability is becoming a benchmark for the quality of companies who offer remediation solutions, the technologies that they develop and offer commercially, as well as the entire projects where they are used. It is, in essence, not something that can be simply ignored in the months and years ahead if standards are to continue to improve, says Tom Hayes of Ecologia. The sustainability ...

  • 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. ...

  • 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 ...

  • 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 ...

  • Bioremediation of ground water by treatment of soil at source with Vaporremed

    A heating oil company during servicing of a home in PA released almost 150 gallons of heating oil that seeped into the basement and below. Ground water was shallow and PA DEP wanted to ensure that the contamination did not pollute the water. The environment company overlooking the cleanup decided to use VaporRemed to reduce the fumes. In three weeks time the level of contamination of the soil and ...

  • Bioremediation replaces “dig and dump” for treatment of pesticides in soil

    Historical usage of organochlorine pesticides (OCPs) such as DDT, toxaphene and dieldrin has resulted in long-term soil contamination, because these substances typically do not degrade naturally at significant rates, so sites are still impacted decades after the end of application. For example, DDT use in Canada ended over 30 years ago, but impacted soil remains at many sites. Such was the case ...

  • In Situ Bioremediation of Chlorinated Solvents

    ABSTRACT: In situ bioremediation is ongoing at a former manufacturing facility in Portland, Oregon.  Shallow groundwater at the site was impacted by chlorinated solvents, primarily trichloroethene and degradation products cis-1,2-dichloroethene and vinyl chloride.  In situ chemical oxidation treatment was completed in 2003 via the injection of sodium permanganate in source ...

  • A Citizen`s Guide to Bioremediation

    What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...

  • 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 ...

  • Bioremediation of an Oil Spill

    Bioremediation is the method of choice to effectively clean up a small spill of hydrocarbons. In this case, five-hundred liters of BTEX has spilled from an above ground storage tank into a pasture that is located at the west edge of the Royal Roads University (RRU) grounds. The soil is classified as a Gleyed Eutric Brunisol based on recent laboratory analysis; it contains clay, but is fairly ...


  • Surfactant enhanced bioremediation (SEB)

    Surfactant Enhanced Bioremediation (SEB®) using Ivey-sol® involve the use of Ivey-sol formulations which are patented non-ionic surfactant mixtures used in the in-situ and ex-situ treatment of petroleum hydrocarbons, heavy metals, and more recently radioactive type contaminated waste. These surfactant formulations have the ability to enhance soil biodegradation. During In-situ and Ex-situ ...

  • 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 ...

  • An Introduction to Bioremediation and its Applications

    A variety of toxic chemicals, metals, and effluents are created and used in industrial processes. These elements need to be degraded to ensure that they do not harm the environment when disposed. A specialized process and equipment are required to perform this task. This is where bioremediation comes in. What is Bioremediation, and what are its Types? In simple ...

  • In situ bioremediation of pesticides in soil and groundwater

    This article provides a summary of the Adventus Group’s experience with treatment of organochlorine pesticides (OCPs) in soil and groundwater using DARAMEND® and EHC® bioremediation amendments. The firm has offered DARAMEND for treatment of recalcitrant compounds in soil for more than ten years in both ex situ and in-situ applications. Since OCPs bind strongly to the soil matrix, ...

  • Petrox Bioremediation of Oil Pipeline Leak

    Petrox bioremediation was used to treat unrefined oil that leaked from a pipeline in Texas.  The oil migrated from the impacted soil into ground water and seeped into the surface water in a nearby river.  After one application of Petrox, the oil concentrations in ground water at the source decreased from 600ppm to less than 100 ppm.  Two more treatments reduced the ...

  • Bioremediation of Effluent the Pulp and Paper Industry

    The treatment of industrial effluent from the paper manufacturing facilities in British Columbia is a major concern because the effluent is discharged into prime salmon habitat in the marine environment (Cross, 1994). High levels of biological oxygen demand (BOD) in the effluent reduce the dissolved oxygen (DO) available to species in the marine environment. In 1988, the Federal Department of ...
