Delineation of hydrocarbon contaminants with multi-frequency complex conductivity imaging

Abstract The characterization of contaminated sites is a serious issue that requires number techniques to be deployed in the field reconstruct geometry, hydraulic properties and state contamination shallow subsurface, often at hundreds meter scale with metric resolution. Among have been proposed complement direct investigations (composed drilling, sampling, laboratory characterization) are geophysical methods, which can provide extensive spatial coverage both laterally depth required However, methods only measure physical indirectly related contamination, their correlation may difficult ascertain without ground truth. In this study, we present successful example where results complex conductivity measurements conducted an imaging framework compared evidence subsoil jet fuel impacted site. Thus, proving combination indirect successfully used image site its (potentially 3D) structure order build reliable conceptual model
