Abstract

Geoelectrical techniques have long standing potential for imaging sites contaminated by dense non-aqueous phase liquids (DNAPLs). Recent work explored the effectiveness of time-lapse DC resistivity to monitor DNAPL source zone remediation. A fundamental component of the work was the development of a unique and comprehensive linkage between well-established DNAPL and DC resistivity models, with the coupled model serving as a cost-effective and valuable investigative tool. The objective of this current study is to evaluate the application of integrated time-lapse DC resistivity and induced polarization (DC-IP) for monitoring DNAPL contamination. This paper introduces the various modelling tools and presents an initial simplistic approach... (More)

Geoelectrical techniques have long standing potential for imaging sites contaminated by dense non-aqueous phase liquids (DNAPLs). Recent work explored the effectiveness of time-lapse DC resistivity to monitor DNAPL source zone remediation. A fundamental component of the work was the development of a unique and comprehensive linkage between well-established DNAPL and DC resistivity models, with the coupled model serving as a cost-effective and valuable investigative tool. The objective of this current study is to evaluate the application of integrated time-lapse DC resistivity and induced polarization (DC-IP) for monitoring DNAPL contamination. This paper introduces the various modelling tools and presents an initial simplistic approach to extend the established DNAPL-DC resistivity modelling framework to incorporate time-lapse IP. Preliminary results are encouraging and ongoing work is focused on developing an advanced hydraulic-electric linkage between the DNAPL and DC-IP models to produce more realistic IP responses from DNAPL spills.
