The soil environmental survey is divided into three stages and the final report preparation. The first stage of environmental investigation includes: data collection, data analysis, site survey, personnel interview, conclusion and analysis, etc., and the main purpose is to identify pollutants. The second stage is the confirmation stage of pollutants with sampling and analysis as the main task. Generally, it can be divided into two steps: preliminary sampling analysis and detailed sampling analysis. Detailed sampling analysis is based on the preliminary sampling analysis to determine the extent and scope of site pollution. If risk assessment or pollution remediation is needed, the third stage of site environmental investigation is required. In the third stage, supplementary sampling and testing were used to obtain the parameters needed for risk assessment and soil and groundwater remediation. The last stage is to prepare the report of preliminary work and output the report.
