Geoelectrical Methods for Detection of Oil Contaminations in Soils and Bioremediation Process Monitoring

The goal of the experiment was to verify the geoelectrical methods as a tool for detection of oil<br>contaminations in soils and to monitor their bioremediation process. The survey area of approximately<br>2000 m2 is situated in the former military camp Borne Sulinowo in NW Poland. The area is covered by<br>fluvioglacial sediments composed of sands and gravels with the first water level at the 11 ¸ 12 m depth.<br>Numerous shallow bore-holes were drilled to recognize the detailed geological structure. The<br>measurements with conductivity meter (Geonics EM-31Mk2) and resistivity Lund Imaging System were<br>carried out and soils samples were taken for laboratory tests in fall 2007.
