  • 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 ...

  • Bioremediating Explosives Contaminated Soil

    From the beginning of World War II until the 1970s, the site that is now the Naval Surface Warfare Center in Crane, Indiana (NSWC-Crane) was the home of a major bomb manufacturing operation. Explosive compounds such as TNT, Royal Demolition Explosives (RDX) and Her Majesty’s Explosive (HMX) were handled loose and drifted through air vents. Often, the material settled on the roofs of buildings, ...

  • 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. ...

  • Biotechnology of hydrocarbon bioremediation in soil washing slurry

    Application of Bioremediation for low cost contaminated soil washing slurry treatment with quick hydrocarbon reduction and improved sustainability. The application uses proprietary microbial formulation with a slurry bioreactor in order to accelerate the degradation process and to make it compatible with soil washing technology. The end result is a treated soil which meets the requirements for ...

  • Bioremediation of petroleum contaminated Soils in Brazil Using AgroRemed

    At Atuba at the corporate site of COPEL, a state owned utility company, soil was heavily contaminated with transformer oil due to a long history of contamination since 1964 probably due to unsafe practices of storage and cleanup. The level of contamination measures as TPH in soil was as high as 766,695 ppm and much of the contamination was at a depth of 1 meter. The site is located on a hill and ...

  • 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 ...

  • 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 ...

  • Cost Savings with Bioremediation

    Introduction Prior operations at a former plating and hard anodizing facility in Santa Clara, California resulted in tetrachloroethene (PCE), trichloroethene (TCE), and cis-1,2-dichloroethene (DCE) impacts to soil and groundwater. In 1987, a groundwater monitoring program was implemented to monitor the plume. In 1998, CDM performed a natural attenuation evaluation for ...

  • SEB Surfactant Enhanced Bioremediation Process Improves F3 & F4 Bioremediation to CCME Guidelines - Case Study

    SEB Surfactant Enhanced Bioremediation process successfully cleans >4,000 Tons of F3 and F4 hydrocarbon contaminated soils at a remote site in Alberta. The SEB process was employed when the subject soils would not respond well to a conventional ex-situ bioremediation treatment. So after a 20 month period of unsuccessful bioremediation; the client and environmental contractor contacted Ivey ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Semifield testing of a bioremediation tool for atrazine‐contaminated soils: Evaluating the efficacy on soil and aquatic compartments

    The present study evaluated the bioremediation efficacy of a cleanup tool for atrazine‐contaminated soils (Pseudomonas sp. ADP plus citrate [P. ADP + CIT]) at a semifield scale, combining chemical and ecotoxicological information. Three experiments representing worst‐case scenarios of atrazine contamination for soil, surface water (due to runoff), and groundwater (due to leaching) were performed ...
