IEG multi level sampling well (MLSW) case study - IEG Technologie GmbH
The MLSW-system is used for the recovery of multiple high-quality samples of soil-gas and groundwater from numerous isolated horizons in a single standard borehole. The system is also used to accurately delineate contamination profiles in three dimensions, which is vital or the design, installation and monitoring of remediation systems. MLSWs also can be used for activly dispersing ...

The Influence of an Integrated Remedial System on Groundwater Hydrology
ABSTRACT This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored natural attenuation ...

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 ...

CH#954 - Diesel/Gasoline Remediation
SITE OWNER: A Truck and Fueling Plaza SITE SURVEY: A tank area that had contained both diesel and gasoline tanks was discovered to have several leaks. The tanks from the pit area were removed. Definition and characterization revealed that not only the tank area was contaminated, but the contaminate plume had migrated under an area where a new building was being constructed. Initial ...

Mechanisms and strategies of microbial cometabolism in the degradation of organic compounds – chlorinated ethylenes as the model
The universal microbial cometabolism provides us with an effective approach to remove man-made xenobiotics. However, the cometabolic bioremediation of toxic organic compounds has not been widely initiated due to the obscure underlying fundamentals in the studies or applications of microbial cometabolism. This review summarizes the current research trends in mechanistic understanding of ...

CH#952 - Oil Contaminated Soil
SITE OWNER: A National Overnight Express Package Company SITE SURVEY: Site and geological surveys revealed a contaminated area north of the facility and west of a diesel tank pit. The cause of the contamination was the result of two (2) underground storage tanks (UST™). One tank contained waste oil while the other contained new oil. Both tanks had been removed. A monitor well was ...

Surfactant enhanced bioremediation (SEB) of F2, F3 and F4 contaminated soils in Northern Alberta - Case Study
Ivey International Inc. (Ivey) was retained to apply the SEB (Surfactant just prior to the on-set of colder northern weather in an area know for -20oC to Enhanced Bioremediation) technology to remediate 2000 tons of F2, F3, and -40oC winter temperatures. The actual period for effective bioremediation in F4 fine grained contaminated soil at a remote site in northern Alberta. The this climate is ...

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 ...

Enhanced Bioremediation of Tetrachloroethene in Central Indiana Glacial Till
ABSTRACT: The goal of this project is remediation of soil and groundwater impacted by tetrachloroethene (PCE) that infiltrated the vadose and uppermost saturated zone below an active dry cleaning facility in central Indiana. PCE was released and transported to depths less than five meters via the primary porosity of thin sand and silt stringers and via secondary porosity of fractures in lodgment ...

Spolchemie site remediation and NanoRem field site application
Site Remediation The Spolchemie site was chosen as one of the NanoRem case study sites, to test two types of nanoparticles (NPs) (zerovalent iron - nZVI and iron oxide NPs) for in situ remediation of BTEX (Benzene, Toluene, Ethylbenzene, and Xylenes) contamination. Nanoremediation was seen as an opportunity to enhance the in situ biodegradation of the BTEX contaminants and to reduce the current ...
