Soil contamination presents a significant hazard to both ecosystems and human well-being. Therefore, there is a need for cost-effective and environmentally friendly approaches to decontaminate polluted soils. Soil remediation involves the treatment of contaminated land to enhance soil quality, safeguarding public health and the ecosystem. Among the promising technologies for remediating soils contaminated with various substances, including inorganic, organic, and mixed contaminants, is electrochemical remediation. Electroremediation (ER) is an in-situ method that employs low direct electric current among electrodes fixed in contaminated soils to create an electric field. This review paper examines the advancements made in recent years in electrochemical remediation as an effective method for decontaminating polluted soil. The discussion begins by exploring electrochemical remediation, followed by the classification of contamination types in soil. The focus then shifts to the application of electrochemical treatment methods for removing heavy metals and organic contaminants from the soil. Additionally, the paper highlights recent progress in the exploration of integrating electrochemical treatment with other remediation techniques, such as phytoremediation and bioremediation.
