preading area through a 1.3 cm deep matrix was reduced with increased moisture content, densely packed matrixes, and higher viscosity oils. Initial contact angle (CA) measurements for all oils was typically lower on clay matrixes due to its sheet-like structure and high absorption capabilities. Individual droplet penetration took longer at lower MC in direct contradiction to bulk kinetics studies, suggesting different spreading behavior across the surface border.

The current document has three goals: 1) summarize the fundamentals in surfactant enhanced aquifer remediation, including the adsorption of hydrocarbons on soil and the mobilization and solubilization of hydrocarbons by surfactants; 2) evaluate the impact of soil geochemistry on surfactants; and 3) interpret the enhancement techniques in applying surfactants in soil remediation. Though such techniques are observed impacted by various factors, by looking into the theories and case studies, this review is expected to provide a tool to help engineers select proper methods in soil remediation.
