Estimating Mass Transfer of Polyaromatic Hydrocarbons from Coal Tar-Contaminated Soil
Many industrial waste disposal/spill sites are characterized by the presence of multicomponent nonaqueous phase liquids (NAPLs) such as gasoline,... -
Indigenous Soil Microflora Versus Introduced Microorganisms in Subsurface Bioremediation
Microorganisms are the main biocatalysts involved in bioremediation processes. Their ability to degrade a large variety of chemical compounds... -
Overview of NAPL Contamination and Reclamation
Groundwater represents the major source of drinking water in most parts of the world. In Israel about 60% of the water supply comes from aquifers.... -
Surfactant-Enhanced NAPL Remediation: From the Laboratory to the Field
Pump-and-treat remediation has routinely been prescribed for subsurface nonaqueous phase liquid (NAPL) contamination. However, pump-and-treat systems... -
In situ Bioremediation of Residual Entrapped NAPL in Aquifers by a Biodegradable Nutrient-Surfactant Mix
Anthropogenic organic compounds are ubiquitous in our technologically oriented society, due to the ever-increasing demands, use and consumption of... -
Retention capacities of immiscible chemicals in unsaturated soils
Retention capacities were measured in the laboratory for n-hexane and tetrachloroethylene (PCE) in three soils at varying soil water contents. Two...

Effective Parameters, Effective Processes: From Porous Flow Physics to In Situ Remediation Technology
This contribution examines the conceptualization of multiphase flow processes on the macroscale, as needed in field applications. It emphasizes that... -
The VEGAS Research Facility: Technical Equipment and Research Projects
In this chapter the research facility for subsurface remediation VEGAS, its possibilities for large scale experiments and the present research... -
Technologies for enhanced remediation of contaminated soils and aquifers: overview, analysis, and case studies
In many industrialised countries, contamination of soils and groundwater from improper disposal of hazardous industrial wastes is an environmental... -
Kinetic constraints on theIn-situ remediation of soils contaminated with organic chemicals
Cleanup of contaminated soils to comply with soil quality limits currently receives much interest. In-situ remediation of contaminated soils relies on...

Bioslurry Treatment of NAPL-Contaminated Soil
Industrial processes related to petroleum refining, coal coking, coal gasification and wood processing result in the production of liquid fuels and... -
Interfacial tension-induced transport of nonaqueous phase liquids in model aquifer systems
Nonaqueous phase liquids (NAPLs) such as solvents and fuels are common contaminants in soils and groundwater. Spills, leaking underground storage...
