4.2.1 Stage I Site Environment Surveys
The first phase of the site environment survey is based on data collection, site reconnaissance and personnel interviews based pollution identification stage, the original
No on-site sampling analysis is conducted. If the first phase of the survey confirms that current and historical areas in and around the venue are not possible
Of the pollution sources, then that the site's environmental conditions are acceptable, the investigation activities can be completed.
4.2.2 Phase II site environment survey The second phase of the site environmental survey is based on sampling and analysis of the pollution confirmation phase, if the first phase of the site environment
Surveys indicate possible sources of pollution in or around the site, such as chemical plants, pesticide plants, smelters, gas stations,
Chemical storage tanks, solid waste disposal and other facilities or activities that may produce toxic and hazardous substances; and due to lack of information such as the original
Due to the inability to rule out the presence of sources of pollution both inside and outside the site, as a potential contaminated site for the second phase site environmental survey,
Determine the type of pollutants, concentration (degree) and spatial distribution. The second phase of the site environment survey can usually be divided into preliminary sampling analysis and detailed sampling analysis in two steps, each step
Including the preparation of work plans, on-site sampling, data evaluation and analysis of results and other steps. Preliminary sampling analysis and detailed sampling
Analysis can be implemented in batches according to the actual situation, and gradually reduce the uncertainty of the investigation. According to the results of preliminary sampling analysis, if the concentration of pollutants did not exceed the relevant national and local standards and clean
