The Use of Electrical Resistivity Method to Mapping The Migration of Heavy Metals by Electrokinetic

Abstract

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.

A Feasibility Study About the Effectiveness of in Situ Electrokinetic Remediation (Ekr) Using Electrical Resistivity Method (Erm)

“…Moisture Content is one of the parameters for electrical resistivity value (Azhar et al, 2017). Therefore, a preliminary analysis was conducted to determine the potential of the soil in absorbing water, which is poured on the soil surface.…”

Geoelectrical and Physicochemical Characterization of Groundwater Contamination around a Cassava Processing Factory in Ogbomoso, Southwestern Nigeria

“…Leachate plumes generated from cassava effluents may contain significant amount of dissolved ions that can substantially raise the conductivities or lower the resistivity of the soil and groundwater which can be detected by the electrical resistivity method [17][18][19]. The 2D electrical resistivity profiling method is particularly suitable for mapping contamination plumes beneath and around waste dumps since it is capable of revealing subsurface variations of resistivity induced by leachate in both lateral and vertical directions from the waste sources.…”

Identification of Groundwater Potential using Schlumberger Array of Resistivity Method in Bulukumba, South Sulawesi

“…By considering some of these factors, the groundwater conditions in an area can be interpreted [11], [12]. The resistivity method is more cost-effective and efficient so that groundwater exploration becomes more practical because abundant and clean aquifer layers can be more easily detected [10], [13], [14], [15].…”
