The authors developed a hybrid-type bioremediation technique for contaminated cohesive soils with petroleum hydrocarbon. Combined techniques for bioremediation are soil improvement with slaked lime to improve air/water permeability of cohesive soils and remediation condition control with geosynthetics. To evaluate the effectiveness of the developed method, laboratory and field model tests were performed with artificial contaminated soil. In the tests, activity of microbe was affected by soil pH, and the effect of soil temperature on the decomposition of petroleum hydrocarbon depended on soil pH. The results suggest that the proposed method of controlling remediation condition is applicable to contaminated cohesive soils.
