“…The purpose of electrical surveys in soils is to determine the specific resistance of the soil and subsurface resistivity distribution through measurements on the ground surface for physical mapping [17,18]. Soil resistivity is determined largely by the content of its electrolyte which consists of moisture content, minerals, temperature and the dissolved salt which have a great influence on the soil resistivity [19,20]. High composition of fine-grained soil such as clay and silt may produce low permeable soil which cause water retention and high in moisture content [21].…”

Abstract. The presence of heavy metals contamination in soil environment highly needs innovative remediation. Basically, this contamination was resulted from ex-mining sites, motor workshop, petrol station, landfill and industrial sites. Therefore, soil treatment is very important due to metal ions are characterized as non-biodegradable material that may be harmful to ecological system, food chain, human health and groundwater sources. There are various techniques that have been proposed to eliminate the heavy metal contamination from the soil such as bioremediation, phytoremediation, electrokinetic remediation, solidification and stabilization. The selection of treatment needs to fulfill some criteria such as cost-effective, easy to apply, green approach and high remediation efficiency. Electrokinetic remediation technique (EKR) offers those solutions in certain area where other methods are impractical. While, electrical resistivity method offers an alternative geophysical technique for soil subsurface profiling to mapping the heavy metals migration by the influece of electrical gradient. Consequently, this paper presents an overview of the use of EKR to treat contaminated soil by using ERM method to verify their effectiveness to remove heavy metals.

“…Since the soil has a variety of geotechnical properties, there are many criteria in classifying soil, e.g., solid materials (soft, medium, and stiff soils); mineral and chemical composition (organic and inorganic soils); water content, the dissolved salt, and so on (Giao 2001(Giao , 2011Prabhakar and Deshpande 2014;Abidin et al 2015), which contribute to fluctuations of the electrical resistivity values. It In the resistivity survey method, two current electrodes and another two electric potential electrodes are the main features of the apparatus.…”

“…The resistivity survey can predict the geotechnical parameters including soil types, chemical properties, and some physical properties of soil: moisture, porosity, and temperature, which are normally used to examine the degree of soil compaction in the laboratory test (Adegboyega 2011;Murad 2012;Prabhakar and Deshpande 2014;Sun et al 2020). Moreover, the pioneering works by Giao (2001) and Adeatyo (2021) have reported that the electric resistivity of soft clay depends not only on the soil material and soil structure but also on the ionic concentration of the pore water.…”

A resistivity-undrained shear strength equation was proposed in this work to investigate the relationship between the undrained shear strength and electrical resistivity of soft Bangkok clay. The field vane shear and screw driving sounding tests were used to evaluate the undrained shear strength of the soft Bangkok clay from 10 field investigations of the canal-side roads. Meanwhile, the electrical resistivity was collected by the low-cost nondestructive resistivity survey method. The relationship between the measured resistivity corresponding to the undrained shear strength was expressed as a linear equation of S u = 7.061ρ with a high statistical correlation (96.20%) between the undrained shear strength and resistivity. The validation between the predicted undrained shear strength from the equation and the measured undrained shear strength from the field sites confirmed the statistically significant relation of data and the reliability of the proposed equation. By using this equation, it successfully predicted the undrained shear strength of the soft Bangkok clay at a depth of 4.00-10.00 m below the ground surface of canal-side roads (zones C, D, and E in the zonation map). The proposed new equation from the resistivity survey in this work, therefore, serves as an alternative tool to fast estimate the shear strength of soft soil in the large area for the preliminary evaluation of road construction.
