In this research, phenol was selected as a representative hydrophilic organic compound and phenanthrene as a representative hydrophobic organic contaminant in petroleum. Fine-grained soil which was manufactured artificially in laboratory was contaminated and EK remediation tests were executed. Also, in order to increase removal efficiency, the surfactant that had been used with improvement technique at the pump-and-treat was used by enhanced method. In the test, the phenol which has high solubility is easily removed, but phenanthrene which has low solubility is almost not. Also, it seems to be the delay phenomenon that the phenanthrene is accumulated near the cathode department vicinity at the enhanced technique which applied the surfactant, but the removal efficiency increases as the surfactant concentration increases. By the test which increases with time, the enhanced method with increasing time is more efficient than the method with increasing surfactant.
