A former natural gas processing station is impacted with total petroleum hydrocarbons (TPH) and benzene. Remedial process optimization (RPO) was conducted to evaluate the effectiveness of the historical air sparging/soil vapor extraction (AS/SVE) sys

Bioventing—the injection of air into the vadose zone to increase microbial activity—is a commonly used, proven technology for remediating volatile organic compounds present in the vadose zone. Passive systems driven by wind or solar power are bot

Colloid transport studies were conducted in water-saturated physically heterogeneous systems to gain insight into the processes controlling transport in natural aquifer and vadose zone (variably saturated) systems. Stable monodispersed colloids (carb

Accurate selection of a surfactant/alcohol formulation for mobilization of organic contaminants from soils requires consideration of oil volume fraction (θO) as a major parameter. This study examines the influence of θO on behavior of systems conta

The air–water interfacial area (a0) was estimated using the surfactant adsorption concept in unsaturated porous media. A column composed of several stainless steel rings was used to carry out saturated/unsaturated experiments in three glass beads m

Reduction of hydraulic conductivity during the treatment of hydrocarbon polluted soils by using surfactants may be an inconvenience for a good recovery of the pollutant. The purpose of the present research work is to determine the main factor respons

A central problem in a real case remediation of an oil contaminated site is the knowledge of the volume and the extent of the pollution. As the estimation of the mass balance, usually based on some point measurements, presents a large range of uncert

[1] Considerable research suggests that colloid deposition in porous media is frequently not consistent with filtration theory predictions under unfavorable attachment conditions. Filtration theory was developed from an analysis of colloid attachment

[1] Although natural soil and aquifer systems often contain layers and lenses of contrasting soil texture, relatively little research has focused on the mechanisms of colloid deposition at textural interfaces. Saturated column studies were undertaken
