The problem of hydrocarbon-contaminated soil has generated interest from government and private institutions through legislation and remediation of these sites, due to recalcitrant compounds being discharged into the environment. Technologies have been developed to help solve this problem. To select the most appropriate technology for contaminated site remediation, the type of pollutant, its concentration, and site conditions must be taken into account. Contamination site remediation treatments are biological, physicochemical and thermal and electroremediation processes.

Soil electroremediation has been reported using different configurations of electrodes connected in series or in parallel, face-to-face, or using a rectangular or circular arrangement, among others. This paper shows the electroremediation of hydrocarbon-contaminated Vertisol type soil using different electrode configurations, a method which uses an electric field to remove contaminants.
