| | Abstract | | Recently, hydrocarbon contamination of soil and groundwater has become an object of public concern. Geophysical techniques are frequently used to characterize hydrocarbon spill sites in Europe and America, but very few in Japan. We have applied electromagnetic mapping and DC resistivity measurement to an investigation at a certain hydrocarbon-impacted site in Japan. In addition, we applied direct push measurements of membrane interface probe and soil conductivity and took some soil core samples in the site for the interpretation of our investigation result. |
