In order to fully understand the pollution situation of the production site left by a coating enterprise and evaluate the risks to the surrounding environment and human health after the development of the site according to the latest planning，the pollution survey and risk assessment of the production site are launched. The field investigation results show that heavy metal pollution mainly exists in the production site，and the concerned pollutants are As，Cr，Pb，Cu，Zn. No organic pollution is found，and the groundwater satisfies the quality standard of groundwater. The results of risk assessment indicate that the carcinogenic risk and hazard quotient of As and Cr in soil through all pathways are higher than the acceptable risk level of 10-6 and 1，respectively，and the total hazard quotient of Cu and Zn through all pathways are less than 1. The carcinogenic hazard and non-carcinogenic hazard of As and Cr have potential health risks to human health，while non-carcinogenic hazard of Cu and Zn would not cause harm to human health. Finally，the target values of soil cleanup for site pollutants are determined as As 50 mg/kg，Cr 400 mg/kg，Cu 300 mg/kg，Zn 500 mg/kg，Pb 280 mg/kg，respectively. It is suggested that remediation measures should be taken for polluted soil to ensure that the soil quality meets the requirements of planned land use.
