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 areas. Subsequent ...

Cost implications of hydrogen donor selection for in-situ bioremediation of chlorinated solvents
The use of enhanced anaerobic bioremediation for treatment of chlorinated solvents in groundwater has increased at a rapid rate within the past three years. Since there are a number of different hydrogen donors that can potentially be used, it is important that practitioners understand the cost implications of the hydrogen donor(s) selected for the project. A comparative economic analysis is ...

Bioaugmentation to Treat Chlorinated Solvents in Fractured Bedrock
ABSTRACT: An in situ bioremediation pilot study was performed at a former industrial site in New Jersey where groundwater has been impacted by historical releases of chlorinated solvents. The target area for treatment is a fractured, intermediate bedrock zone. The remedial objective at the Site is to treat the groundwater while minimizing the impact of the remedial system on the re-development of ...

Compatible Technologies to Improve In-Situ Remediation of Chlorinated Solvents: A Case Study
Abstract: A chlorinated solvent plume (perchloroethylene or PCE) was discovered in the shallow ground water as a result of historical operating practices surrounding a Houston area dry cleaning facility. Permeable shallow soil at the site allowed rapid vertical migration at the source and lateral migration in the shallow ground water. This migration resulted in an off-site migration of the plume ...

Remediation of Chlorinated Solvents - Case Study
Project Location: SW Florida Client: DoE Contamination: TCE, PCE, Vinyl Chloride, Toluene Site Size: 4+ Acres Project Description: Over the previous 13 years, the incumbent remediation contractor had attempted to removed a large chlorinated solvent plume extending 20+ feet below grade, covering a footprint of approx. 4+ acres, with an elaborate vertical well pump-and-treat system. The ...

Aerobics to the Rescue - Using Compatible Technologies to Improve Groundwater Remediation
Background Increased opportunities for contaminated property redevelopment have propelled property owners to evaluate options for accelerating site remediation. In some cases a containment technology may have been implemented to mitigate the off-property migration of contamination as the most practical option at the time. Focusing on the property's redevelopment potential, there is new ...

Raynesway resource park - Case Study
The Raynesway Resource Park is a 35 hectare site bounded on three sides by the River Derwent. The southern half of a former chemicals plant, soils and groundwaters were impacted by chlorinated solvents, acid tars, hydrocarbons and ammoniacal sludges. Celtic designed a sophisticated groundwater treatment system, integrating air sparging, multi-phase extraction and chemical oxidation to address ...

Bioremediation: An Eco-Friendly Solution For Environmental Cleanup
Introduction Bioremediation is the use of microorganisms, or their enzymes to clean up environmental pollutants. It is a sustainable and cost-effective approach to clean up contaminated soil, water, and air. Bioremediation can be applied to a variety of pollutants, including petroleum, pesticides, and solvents. Bioremediation is a complex process that involves various biochemical reactions, ...

Multiparameter sonde used in combined remedy approach and saves $200,000 in potential costs - Case Study
A former dry-cleaning site in the Pacific Northwest, Ultra Custom Care Cleaners, was found to be contaminated with PCE (perchloroethylene). According to the U.S. Geological Survey (USGS), PCE was widely used in the dry cleaning of fabrics since the 1940s. PCE is one of the most frequently detected VOCs (volatile organic carbons) in groundwater at a national scale (Moran 2004). PCE is highly ...
