1 In-Situ Purification Technology that orresponds to the Soil ontamination ountermeasures Law Revision VODM-e VO2 VO The Soil ontamination ountermeasures Law revision was enforced in April Expected to increase the number of employed in-situ cleaning method instead of the law which was the major excavation. In this report, we point to organize the revision of the Soil ontamination ountermeasures Law, and introduced the features of embodiment situ purification technologies. First isdm-e Methodto purify for volatile organic compoundsvoand the second isin situ flushing methodfor cleansing oil and VO hief Researcher, Research & Development Institute 2Research & Development Institute 1
