In this study, electrokinetic remediation tests were performed with spiked fine-grained soil by phenanthrene which is representative hydrophobic organic contaminant of petroleum hydrocarbon. And also, the enhanced method was used with surfactant concentration variation and elapsed time to achieve more higher removal efficiency than conventional electrokinetic treatment. In conventional electrokinetic treatment, most phenanthrene was not transported. But, in the enhanced method used by the surfactant, phenanthrene moved form anode to cathode region and accumulated in cathode region. Also, the transportation rate of phenanthrene was increased with surfactant concentration increasement and elapsed time.

In this study, Isolation was attempted to acquire a phenol utilizing bacterium for PAH degradation and to investigate the characteristics of PAH degradation. The isolate was identified by BIOLOG test as Stenotrophomonas maltophilia. Lower first order reaction constant was detected in the presence of lower phenol concentration. The yield coefficient of phenol was 0.1447mg cell/mg phenol. In the presence of naphthalene and phenol, phenol degradation was favorable. The isolate was capable of utilize naphthalene and phenanthrene as growth substrate but PAH, containing over 4-ring structure such as pyrene, was not degradable. The possible phenanthrene degradation pathway would be the addition of two hydroxy group on C-1 and C-2 position, followed by ortho cleavage, and then decarboxylation.
