Description:
A direct push resistivity method was evaluated as a complementary screening tool to provide rapid in-situ contaminant detection to aid in better defining locations for drilling, sampling, and monitoring well installation at hazardous waste sites. Nine continuous direct push resistivity soundings were performed at Operable Unit 1, Hill Air Force Base, Utah in June 1995. Following the pushes, discrete soil samples were collected using a hollow stem auger at locations adjacent to each push-hole. Core samples were analyzed for total petroleum hydrocarbons, and ten individual organic chemical compounds. To evaluate the resistivity methods, resistivity data were compared with the results from laboratory soil analyses. Although statistical correlations are poor between resistivity and analytical results, mapping of the resistivity distribution using a three-dimensional interpolation technique did provide valid screening-level delineation of the contaminant distribution.
