Abstract
In 1995 and 1996 the US Geological Survey ma& 40 Schlumberger dc electrical resistivity soundings at the<br>Norman Landtill, near Norman, Oklahoma. Interpretation of the resistivity data indicates that high resistivities<br>(>300 ohm-m) are related to dry sand, intermediate resistivities (45-300 ohm-m) are related to freshwater saturated<br>sand, and low resistivities (~45 ohm-m) are related to fine-grained materials or materials saturated with the<br>conductive fluids. Interpreted resistivity maps show a low resistivity anomaly that extends from under the landfill to<br>just past a nearby slough. This anomaly corresponds to known areas of ground water contamination. A resistivity<br>cross section, constructed from interpreted Schlumberger soundings, shows that this low resistivity anomaly is about<br>5 m deep and up to 9 m thick.
