“…Line-1 was laid on the beach and was about 220 m long, and the investigation depth in this line reached 50 m; Line-2 was located inland, was 165 m long and reached an investigation depth of about 40 m. The different lengths and spacing between Line-1 and Line-2 was because of the space availability and the desired depth of data penetration. Although dipole-dipole arrays are known to produce a low signal to noise ratio, they are an effective configuration for interpreting complex structures and dispersion plume anomalies, because they provide high-resolution data [25]. Consequently, Line-1 and Line-2 were necessary for identifying the distribution of seawater plumes, for which high-resolution data were required and it was reasonable to implement a dipole-dipole configuration in this study.…”

The coastal areas of Phuket Island are facing the risk of seawater intrusion, because intense anthropic activity due to urbanization and the expansion of tourism influences coastal hydrologic systems. Indeed, the Kamala sub-district—on the western part of Phuket Island—is a well-known and attractive destination for tourists. Previous research indicates that there is likely to be a seawater intrusion in Kamala. The main purpose of this study was to delineate the seawater intrusion problem in a coastal aquifer in Kamala. Geo-electrical surveys of four lines were successfully conducted in the study area. Two-dimensional (2D) inversion models from the resistivity data show high-resolution subsurface resistivity anomalies of seawater intrusion. The concentration of the seawater intrusion decreases eastward toward the inland areas. Based on a sample measurement, the contaminated zone of seawater has a resistivity value smaller than 30 Ohm-m, and the empirical relationship between the formation conductivity and fluid conductivity of the study area was established. Finally, time-lapse Electrical Resistivity Imaging (time-lapse ERI) was conducted to prove that there was no presence of clay layers in study area; thus, the low resistivity plumes (smaller than 30 Ohm-m) were scientifically interpreted as being seawater intrusion.

“…Frequency based spectral Induced Polarization has been applied to monitoring of stimulated bioremediation of uranium contamination with promising results [5]. The method has been used in landfill characterization [6][7][8][9][10][11][12], spatial and temporal distribution of leachates [13][14][15], and gas migration within landfills [16,17]. Furthermore, the method has been used in sites contaminated with Non-Aqueous Phase Liquids (NAPLs) for characterization [18][19][20][21][22] and monitoring of the changes due to remediation [23,24].…”

Multidisciplinary Characterization of Chlorinated Solvents Contamination and In-Situ Remediation with the Use of the Direct Current Resistivity and Time-Domain Induced Polarization Tomography

Soil contamination is a widespread problem and action needs to be taken in order to prevent damage to the groundwater and the life around the contaminated sites. In Sweden, it is estimated that more than 80,000 sites are potentially contaminated, and therefore, there is a demand for investigations and further treatment of the soil. In this paper, we present the results from a methodology applied in a site contaminated with chlorinated solvents, for characterization of the contamination in order to plan the remediation and to follow-up the initial step of in-situ remediation in an efficient way. We utilized the results from three different methods; membrane interface probe for direct measurement of the contaminant concentrations; seismic refraction tomography for investigating the depth to the bedrock interface; and direct current resistivity and time-domain induced polarization tomography to acquire a high-resolution imaging of the electrical properties of the subsurface. The results indicate that our methodology is very promising in terms of site characterization, and furthermore, has great potential for real-time geophysical monitoring of contaminated sites in the future.

“…If the subsurface electrical properties remain constant over time, time-lapse measurements can track changes in subsurface conductivity associated with an induced or natural input (Singha et al 2014). ERI and time-lapse ERI have been extensively used to image shallow groundwater movement (Koestel et al 2009;Doetsch et al 2012), groundwater contaminant migration (Casado et al 2015;Kuras et al 2016;Park et al 2016), contaminant remediation (Ramirez et al 1993;Daily and Ramirez 1995;Halihan et al 2011;Johnson et al 2015), and solute transport (Slater et al 2000;Kemna et al 2002;Singha and Gorelick 2005;Muller et al 2010). Permanent ERI installations have been used to monitor hydraulic processes in porous media (e.g., Kuras et al 2009).…”

Feasibility Assessment of Long‐Term Electrical Resistivity Monitoring of a Nitrate Plume

Long‐term monitoring solutions at contaminated sites are necessary to track plume migration and evaluate the performance of remediation efforts. Electrical resistivity imaging (ERI) can potentially provide information about plume dynamics; however, the feasibility and likelihood of success are seldom evaluated before conducting a field study. Coupling flow and transport models with geoelectrical models provide a powerful way to assess the potential effectiveness of an actual ERI field campaign. We present a coupled approach for evaluating the feasibility of monitoring nitrate migration and remediation using 4D time‐lapse ERI at a legacy nuclear waste facility. This kilometer‐scale study focuses on depths below the water table (∼70 m). A flow and transport model is developed to perform simulations of nitrate migration and removal via a hypothetical pump‐and‐treat system. A tracer injection is also simulated at the leading edge of the nitrate plume to enhance the conductivity contrast between the native subsurface and the groundwater fluids. Images of absolute bulk conductivity provide limited information concerning plume migration while time‐lapse difference images, which remove the static effects of geology, provide more useful information concerning plume dynamics over time. A spatial moment analysis performed on flow and transport and ERI models matches well during the tracer injection; however, inversion regularization smoothing otherwise limits the value in terms of locating the center of mass. We find that the addition of a tracer enables ERI to characterize plume dynamics during pump‐and‐treat operations, and late‐time ERI monitoring provides a conservative estimate of nitrate plume boundaries in this synthetic study.
