“…Dwidedi and Upadhyay [6] reviewed the prior data on interphase mass transfer in packed beds and showed that it is inversely proportional to the void fraction of the medium. One of the earliest investigations focusing on NAPL contamination in porous media was conducted by van der Waarden et al [31]. The authors showed that NAPL dissolution from unsaturated porous media is a much more complex process than dissolution of solid particles such as benzoic acid spheres in porous media even though there are similarities between the two.…”

“…They are relatively limited in scope, focusing on a very few contaminants and soil types. Van der Waarden et al (138) presented the results of a series of column experiments using fine glass beads as the porous matrix. A mixture of hydrocarbons was injected into the unsaturated zone and permitted to redistribute.…”

Over the past two decades, a number of models have been developed to describe the multiphase migration of organic chemicals in the subsurface. This paper presents the state-of-the-art with regard to such modeling efforts. The mathematical foundations of these models are explored and individual models are presented and discussed. Models are divided into three groups: a) those that assume a sharp interface between the migrating fluids; b) those that incorporate capillarity; and c) those that consider interphase transport of mass. Strengths and weaknesses of each approach are considered along with supporting data for model validation. Future research directions are also highlighted.

“…In the case of groundwater contamination by hydrocarbons spilling, one of the most important problems is how to recover the long-term pollution source, residual hydrocarbons trapped in a porous medium ( − ). Since passive remediation techniques, such as pump and treat of the contaminated groundwater and excavation of the polluted soil followed by on-site treatment are often costly, time intensive, and even insufficient, there is increasing interest in confining the pollutant or applying in situ treatment to the contamination source.…”

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 responsible for this reduction and by the same way to give an application solution to this problem. Experimental studies on sand filled laboratory columns have shown that the reduction of hydraulic conductivity can be due neither to the precipitation of the anionic surfactants in the presence of calcium ions nor to the clay minerals present in small proportion in the porous medium. We point out that this phenomenon is essentially due to the agglomeration of micelles and show that addition of 4 wt % of butyl alcohol under specific conditions contributes to improving both the injectability of the surfactant solution and the efficiency of the treatment. The optimized surfactant formulation, containing a mixture of two commercial surfactants and this cosolvent, palliates the reduction of hydraulic conductivity and decreases the interfacial tension by a factor of 100. As a consequence, after three pore volumes of injected surfactant solution, 85% of the trapped oil is removed compared to 11.4% obtained without cosolvent.
