The Industrial Park is located on Zengcheng District, Guangzhou. After collecting soil and groundwater samples from the site, it is found that the site has a large range of pollution, and the polluted soilis removed and landfilled. After several repairs and renovations, the soil of the restored site was collected and tested by the laboratory. The soil quality was gradually improved and up to standard for use. The site has been incorporated into the “three old” reconstruction plan of Guangzhou. The nature of land use will be transformed from industry to second-class residential land, alleviating housing pressure in Guangzhou and creating great value for urban development.
