To avoid soil and groundwater pollution in factories threatening national health and environment, Environmental Protection Administration (EPA) has launched “Demonstrative Project Applying Investigation of Soil and Groundwater Pollution Potential in Operating Factories” (“demonstrative project”) since 2014, and also launched “Applying Investigation of Soil and Groundwater Pollution Potential in Operating Factories (II)” (“project II”) since 2016. This investigation is focus on the inventory and manufacturing procedures of operating factories and conduct the selection and investigation systematically. For continuation of the early project, the purpose of this project is to expand the implementation of the investigation, to keep abreast of the list with common potential pollution in hand, and pay attention to feature of manufacturing and operation. According to the results of the on-site survey in 144 factories and investigations in 24 factories, exceedances of the Control Standards are found in 12 factories (about 50%), dominated by metal pollution. Moreover, 6 factories are exceeded of Soil Pollution Control Standards; and 2 factories are exceeded of Groundwater Pollution Control Standards (II Class); exceedances of Soil and Groundwater Pollution Control Standards are found in 4 factories. All the pollutants in investigated factories are confirmed, and then the factories have been controlled by the Soil and Groundwater Pollution Remediation Act (SGPRA). Through the results feedback in this project, provides the directions of promoting factories pollution prevention management system. Additionally, traces of controlled pollutants as well as frequent situation of abnormal samples and water quality are found underground during the investigation. This project has conducted pollution prevention and coaching process in 7 selected factories, building the management ability for factory pollution prevention which is suitable for each factories. The performances are compiled into the manual for factory’s self-management, pollution prevention and the case study. Through this project, the manufacturing process with high potential of pollution in groundwater and the manufacturing features will be obtained, which is efficient to restrain those illegal industries and reinforces their tendency against unlawful conducts under limited government resources. It could not only eliminate pollutions in subsurface environment, but establishes the comprehensive fundamental of further factory prevention management and law amendment.
