  • 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 ...

  • Bioremediation in Denmark - a case study

    Back in the 1990s the closure of several fuel stations in Denmark led to extensive land contamination as underground storage tanks gradually began leaking. After six years of attempted clean-up by the companies concerned the regulatory bodies concluded the situation had not been sufficiently addressed. As a result they refused to complete payment schedules which were based on the success of the ...

  • 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 ...

  • Replacement of Expensive Groundwater Pump and Treat System Pump and Treat System with Bioremediation

    Introduction Prior operations at a former Microwave electronics facility inSunnyvale, California, resulted in tetrachloroethene (PCE), trichloroethene ( TCE), cis-1,2-dichloroethene (DCE) and vinyl chloride (VC) impacts to soil and groundwater. In 1985, a groundwater pump and treat (P&T) system was implemented to address groundwater impacts. In 1996, CDM began ...

  • 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 ...

  • 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 ...

  • In-Situ Bioremediation Treats Contaminants at a Disposal Site

    Site Summary A TCE-contaminated plume developed from buried drums containing organic solvents on the former Duluth Airbase. Soil excavation took place in the early 1990s and a total of 1,925 yds3 of soil were treated through land farming. A few years later, site assessment activities uncovered a VOC plume in groundwater and further monitoring revealed the breakdown of TCE to daughter products ...

  • 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 diesel spill - cumbria, united kingdom

    Introduction Microbac has successful undertaken the clean up of a diesel spill at a site in Cumbria. The oil escaped from a large storage tank, located at the top of an incline after a problem occurred with closure of the valve. The position of the spill resulted in oil running down the incline and into the site drainage system. In response to the client"s request, Microbac ...

  • 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 Oily Bilge Water Using BilgeRemed On M/V Cape Wrath

    The study was undertaken for Crowley Shipping Company, managers for reduced Operational ships or ROSS ships to evaluate BilgeRemed for complete reduction of oil in the oily bilge water. The oily bilge water in these ships is collected by contracted trucks who transport the bilge water for off-site disposal and is generally a very expensive operation. In a cost cutting effort a study on effect of ...

  • JP-4/JP-8 Bioremediation Using ORC® Pumped into Permanent Injection Wells (PDF)

    At Nellis Air Force Base, Nevada, a site investigation revealed that two separate floating product plumes and a larger dissolved plume consisting of JP-4 and JP-8 jet fuel existed. Floating product thicknesses ranged from less than one-half inch to almost three feet. The length of the dissolved plume extended about 700 ...

  • Assessment of Biodegradation Processes at a Complex Site: Decision Strategy and Implications for Enhanced Bioremediation (PDF)

    A Superfund site in Ohio overlies groundwater contaminated with chlorinated aliphatic hydrocarbons (CAHs)—including perchloroethene (PCE), trichloroethene (TCE), cis-1,2- dichloroethene (DCE), and vinyl chloride (VC) — from prior solvent use and disposal in onsite ponds. The ponds and surface soils containing CAHs were removed in 1984. Historical solvent use and disposal practices produced a ...
