  • 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 ...

  • Sono-biodegradation: a promising alternative to existing bioremediation methodologies

    Pollution of fresh water has become a serious concern today for developing countries. There are umpteen treatment methodologies and protocols, but still there exists a demand for new technologies for wastewater treatment. Extensive research on pollutants and increased toxicological studies have paved the way for new technologies, such as ultrasound treatment of pollutants and wastewater ...

  • Principles and practices of enhanced anaerobic bioremediation of chlorinated solvents

    PROBLEM STATEMENTThe Department of Defense (DoD) has identified hundreds of sites where groundwater is contaminated with chlorinated solvents; these represent one of the DoD’s largest remediation liabilities. In addition to their use in many industrial processes, chlorinated solvents have historically been used for cleaning and degreasing such diverse products as aircraft engines, automobile ...

  • A Systems` Approach to In Situ Bioremediation: Full-Scale Application (PDF)

    An 18-month, in-situ biological program, specifically aimed at accelerating the current attenuation process such that the owner can sell the property began May 5, 2000. The remedial approach has focused on population management, nutrient augmentation, terminal electron acceptor enhancement, and an efficient subsurface delivery of the enhancement liquids. Specifically, a novel delivery system, ...

  • ISCR-Enhanced Bioremediation Accelerates Groundwater Cleanup at Active Manufacturing Facility

    In the winter of 2008, full-scale in situ chemical reduction (ISCR) was implemented as a removal action at the Siltronic Corporation site in Portland, OR, to treat a source area contaminated by releases of TCE. The source area was considered to be the portion of the site with concentrations of TCE in groundwater greater than 11,000 µg/L, suggesting the ...


  • High Benzene Concentrations Reduced Using ORC Advanced

    Site Summary Elevated levels of petroleum hydrocarbons were discovered near the former dispenser island at a former servicestation in Sheboygan, WI. In hopes of reducing concentrations, soil excavation activities took place in June 2003. Atotal of 500 tons of hydrocarbon-impacted soils were removed and transported to a landfill for disposal. However,residual contamination continued ...

  • 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 ...

  • Replacement of P&T with ORC Advanced Reduces Cost to Closure

    Site Summary Two leaking USTs resulted in soil and groundwater contamination at a service station in Michigan. Naphthalene, trimethylbenzene (TMB) and BTEX contamination were discovered in the subsurface prompting the need for remedial cleanup. Michigan DEQ began remediation via UST removal and soil excavation. A total of 4,000 cubic yards of contaminated soil was removed. A pump and treat ...

  • Applied science drives commercial decision-making

    Site remediation has evolved from energy intensive, mechanically driven remediation processes to more effective and less expensive in-situ processes. The most common in-situ remediation technology is bioremediation although knowledge of in-situ chemical treatments has advanced significantly and it is now frequently implemented on contaminated sites. Microorganisms in the ground have the ability ...

  • Smith street case study

    The Smith Street site is situated in Scunthorpe, Lincolnshire. Historically, the site had been utilised as a commercial vehicle sales centre and repair garage. These activities featured fuel pumps with associated under and above ground storage tanks. At some point, there was believed to have been a release of fuel from one of the above ground storage tanks. The contamination encountered was ...


  • Aquifers and hyporheic zones: Towards an ecological understanding of groundwater

    Ecological constraints in subsurface environments relate directly to groundwater flow, hydraulic conductivity, interstitial biogeochemistry, pore size, and hydrological linkages to adjacent aquifers and surface ecosystems. Groundwater ecology has evolved from a science describing the unique subterranean biota to its current form emphasising multidisciplinary studies that integrate hydrogeology ...

  • Horizontal Wells - Technology Overview

    Horizontal well technology has been incorporated into many current environmental remediation applications (and associated contaminants), such as in situ bioremediation, air sparging, vacuum extraction, soil flushing, free product recovery, etc. Ac cording to information reviewed, this technology is most applicable to sites with relatively shallow soil and/or groundwater contamination, and can ...

  • In situ Remediation of 1,4-Dioxane using Electrical Resistance Heating

    An increasing number of states are establishing enforceable 1,4-dioxane cleanup goals due to recent improvements in analytical detection methods and existing carcinogenic risk information for 1,4-dioxane. Historically, 1,4-dioxane was used as a stabilizer for chlorinated solvents, primarily 1,1,1-trichloroethane. In addition, 1,4-dioxane has been used in a broad range of products including but ...

  • The “Straight Skinny” on bentonite-based drilling muds & their standard practice use in the horizontal remediation well industry

    Let’s make our point up front: 1) bentonite-based drilling fluid is NOT bad for horizontal remediation well (HRW) projects; 2) it does not damage the formation; 3) it is a naturally occurring clay material that is mined; and 4) it does flush easily/adequately during well development. Most remediation professionals have designed and/or installed vertical wells at one time or another ...

  • Stevens Systems Enhances Ground Water Remediation Effectiveness

    The Stevens Hydra Probe is now being used to monitor the progress of a new groundwater pollution clean up method called phytoremediation. Phytoremediation is the method by which trees are used to pull contamination out of groundwater. Remediation of contaminated aquifers can take many years to complete. The need for clean, healthy rivers, lakes and streams has stimulated research to develop ...
