This paper, based on a case study on a remained site by relocated electroplating factory in Chongqing, analyzes the heavy metals concentration in the soil with results showing Cr concentration at 22.7 to 378 mg/kg, averaging 72.2 mg/kg, Ni at 19.8 to 1 220 mg/kg, averaging 127.8 mg/kg, 12.9% and 16.1% respectively over the standard, and 1.99 and 24.4 times at maximum by “Fair Land Soil Environmental Quality Appraisal Standard (HJ350-2007)”. According to “Risks Assessment Technical Guidelines of Polluted Sites (HJ25.3-2014)”, this paper conducted a health risk assessment on Cr (VI) with all samples over the acceptable level 1.0×10^-6 in comprehensive carcinogenic threshold limit, up to 1.41×10^-4. Exposure through mouth and breath. Measures must be taken to ensure the environmental safety before redevelopment of industrial sites. 
