Heavy metal contamination in soil has become a global issue that demands adequate attention and resolution. The related soil contaminant may affect human health and other living organisms in the ecosystem. Electrokinetic Remediation (EKR), which is a green technology-based approach that promotes a sustainable ecosystem, can be be used to resolve soil contaminated with heavy metals. Ex situ analysis has shown that more than 50 percent of electrokinetic remediation successfully removes heavy metals in soil. Hence, it is crucial that in situ remediations be implemented in field and environmental contexts. However, there are some challenges and a lack of guidelines on the field application of in situ remediations. This paper aims to propose a design guideline on in situ remediation application in field and environmental contexts based on a pilot study. The electrokinetic process of uncontaminated soil was conducted using a pure system. Preliminary data based on electrical resistivity tomography (ERT) before and after the remediation process were also applied.
