Vanadium is a typical redox-sensitive element that is abundant in the crust and is a superior catalyst in modern industry. Due to the geological weathering and intensive human activities such as mining, smelting and applications, vanadium pollution in soil and groundwater is becoming more and more serious, arousing widespread concern of researchers. This article reviews the latest research progress of remediation of vanadium contamination in soil and groundwater from three aspects: physical methods, chemical methods and biological methods. Physical methods include soil replacement and electrolysis. Chemical methods include chemical leaching, chemical adsorption and chemical reduction immobilization. Biological methods include phytoremediation and microbial remediation. Meanwhile, the trend of the development in remediation technology of vanadium contaminated soil and groundwater is also forecasted, which will provide reference for subsequent researches
