Remediation of the contaminated soils is required urgently, especially for the sites with high environmental risk, threats to human residence and health, and social stability. In the paper, remediation technologies and current problems were discussed with “Demonstration Project of Soil Remediation on The Periphery of Guixi Smelter” as an example, and the prospects of heavy metal contaminated soil remediation were also discussed.
