General physical examination for Soil and Groundwater Potential Contamination of Abandoned Factories

The project was the first year of the General Physical Examination for Soil and Groundwater Potential Contamination of Abandoned Factories. In this project, totally 34,827 abandoned factories were surveyed to obtain the current land uses and operation characteristics. According to the result of 34,827 abandoned factories surveys in this project and the screening principles in the project of “Environmental Risk Integration and Industrial Sites Screening Risk Map Construction” conducted by Taiwan EPA in 2012, 105 sites were selected as high priority sites for environmental assessments. Base on the assessment results and the quantitative screening system, 20 sites were selected as high priority sites for investigation and further verification if needed. In the investigation stage, the preliminary investigation of soil and groundwater was executed for the 20 sites. Totally 16 of the 20 sites were selected for further verification in order to confirm the concentration of contaminates and extent of contamination. The results indicated that the soil or groundwater was contaminated in 15 of the 16 sites verified. It is recommended that these contaminated sites should be declared as the Soil and Groundwater Pollution Control Sites according to the Article 12 of Soil and Groundwater Pollution Remediation Act or necessary response measures should be implemented according to the Article 7, Paragraph 5 of the Soil and Groundwater Pollution Remediation Act. For the purpose of completing nationwide abandoned factories surveys, investigations and verifications in limit time, and ensuring the qualities of the results, a computer-assisted system including cloud computing and tablet PCs had been established in previous projects. In this project, the computer-assisted system was updated and integrated with results of the current surveys, environmental assessments, investigations, and verifications. Using the computer-assisted system enabled to enhance the efficiency of investigation and supervising management. Moreover, other tasks including brochure productions, educational materials, workshops of pollution prevention of land, 3- Dimension animation of project achievements, and formulation of strategy and management framework were completed in this project as well. Strategy and management framework could be used as future reference of conducting investigations and controlling of abandoned factories.
