The detailed survey result estimate the contamination depth which executes the TPH(total petroleum hydrocarbon) soil detailed survey of analysis result is, about 0.25 ～ 3.0m the contamination area 836㎡, the contamination volume is 918.9㎥. But the tank bottom where the investigation is impossible and considering a circumference facility, the contamination soil will be able to increase. Consider the TPH(total petroleum hydrocarbon) concentration of analysis result, hereupon it will try to present the demobilization method which is suitable recommend Land Farming and Biopile.
