“…As ERT has the ability to produce high resolution images of formations at shallow depths, it is widely used in geology, archaeology, engineering, and environmental surveys (Bowling et al 2007;Soupios et al 2007a;Chang et al 2012;Lin et al 2013;Loke et al 2013;Tong et al 2013). Furthermore, ERT, undertaken in environmental contamination research such as investigations of landfills and groundwater contamination sites, can be used to clarify the scope and depth of landfills, investigate spills in contaminated areas, identify possible leakages, or assess the spatial distribution of contaminants (Atekwana et al 2000;Halihan et al 2005;Soupios et al 2007b;Yang et al 2008;Atekwana and Atekwana 2010;Martínez-Pagán et al 2010;Vaudelet et al 2011;Ayolabi et al 2013;Wang et al 2015). More specifically, cross-hole electrical resistivity tomography (CHERT) involves placing current and potential electrodes in boreholes.…”

Time-lapse methodology was applied to cross-hole electrical resistivity tomography (CHERT) to investigate two groundwater contamination sites. In the first case study, resistivity profiles were used to delineate the transport direction and spatial distribution of the contaminant, which can serve as a basis for adjusting the remediation treatment by the remediation team. In the second case study, changes in electrical conductivity were used to evaluate the remediation reagent's transport direction and area of effect, and this was used to indirectly verify the effectiveness of the remediation efforts. CHERT equipment was installed simultaneously at the monitoring wells, which enhanced the benefits of the boreholes, enabling them to be even more economical. In large-scale groundwater contamination sites or sites with complex hydrogeological environments, application of CHERT techniques can result in greater amounts of data, particularly in analyzing localized preferential flow paths. This data would be greatly beneficial to the remediation of groundwater contamination sites and long-term groundwater management.
