This project collects European and American case studies of well head protection, watershed management, and environmental risk management, and also collects the basic data of ten major groundwater zones in Taiwan to interpret many facts such as hydrogeological characteristics, groundwater quality deterioration, pollution resource, and then to accomplish the groundwater pollution source management strategies. For groundwater zones (Alluvial Fan of Zhuoshui River, Pingtung plain, and Chianan plain) with large quantity of groundwater recharge and usage, and poor groundwater quality, the Alluvial fan of Zhuoshui River was preferentially selected to establish the pollution source management strategies of specific areas by simulating the influence of the recharge areas and high practical flow migration. As for the protection of public drinking water well, the management strategies such as the list creation of pollution sources within Zone of Influence, pollution potential assessment and monitoring enhancement were also proposed. Five groundwater recharge areas at alluvial fan of Zhuoshui River were conducted to investigate the groundwater pollution and simulate the pollution range. The results showed that the Zone of Influence was 300 meters and also came to suggest three management guidelines for agricultural and industrial sources including “long–term monitoring on the transport characteristics and deterioration potential of groundwater quality in recharge areas with good permeability”, “disclosing monitoring data of high pollution potential industries”, and “building the method for evaluating the correlation between pollution potential and agricultural sources”.
After evaluating the life-cycle periods of industrial park from establishment to disbandment, this project proposes intensified soil and groundwater quality management works in industrial parks including effective monitoring management, light indicator of pollution management, responsibility of emergency response, and cluster pollution sites with unknown polluter. Quantitative indicators such as the monitoring efficiency ratio of high pollution potential factories, the downtrend of groundwater pollution and the technical training investment were proposed to evaluate the motivation of soil and groundwater management in industrial parks. After analyzing the monitoring efficiency ratio in 18 industrial parks with red and orange light pollution indicators, the advanced management plan were proposed to increase the monitoring efficiency in industrial parks. The regulation, “notification and response procedures to abnormal monitoring results in industrial parks”, was revised to strengthen the responsibility of emergency response. The integrity of pollution source investigation was evaluated by assessing facts such as pollution sources, pollution condition and authority. Four management measures were proposed to clarify the attribution of responsibility of eight cluster pollution sites. In considering the proposed management measures and user feedback, six printing reports were implemented to extend the soil and groundwater management system of industrial parks. The implemented reports comply with the requirement of questionnaire function with quantitative indicators and future online reporting with systematic analysis to effectively track the pollution declarations and site history in industrial parks.
