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. |
