In response to increasing natural surfactant demand and environmental concerns, natural
plant-based surfactants have been replacing synthetic ones. Saponins belong to a class of …

Ex situ soil washing is commonly used for treating contaminated soils by separating the most
contaminated fraction of the soil for disposal. Surfactant-enhanced soil washing is being …

Biodegradation of hydrophobic organic compounds inpolluted soil is a process involving
interactionsamong soil particles, pollutants, water, andmicro-organisms. Surface-active …

We describe a three-dimensional, multicomponent, multiphase compositional finite-
difference simulator for application to the analysis of contaminant transport and surfactant …

The potential for nonaqueous phase liquid (NAPL) mobilization is one of the most important
considerations in the development and implementation of surfactant-based remediation …

We review the current status of modeling multiphase systems, including balance equation
formulation, constitutive relations for both pressure-saturation-conductivity and interphase …

In this paper we present a partitioning interwell tracer test (PITT) technique for the detection,
estimation, and remediation performance assessment of the subsurface contaminated by …

A number of previous studies are reviewed to examine the actual reduction of NAPL from
source zones and the effectiveness of the specific technique of remediation used at sites …

An anionic monorhamnolipid biosurfactant produced by Pseudomonas aeruginosa was
investigated for its potential to remove residual hexadecane from sand columns. In a series …

One major problem with tetrachloroethene (PCE) contamination of aquifers is its ability to
form dense, nonaqueous-phase liquids (DNAPL), which can act as a persistent …
