This project collects European, American, Japanese and Korean case studies of well head protection and watershed management, and also collects the basic data of 10 major groundwater zones in Taiwan, aiming to interpret many facts such as hydrogeological characteristics, groundwater quality deterioration, pollution resource, and afterwards to accomplish the groundwater pollution source management strategies. For groundwater zones (Pingtung plain and Chianan plain) with large quantity of groundwater recharge and usage and poor groundwater quality, the Pingtung plain was selected to establish the pollution source management strategies of specific areas. 5 groundwater recharge areas at Pingtung plain and 63 public drinking water well and the surrounding area were conducted to investigate the groundwater pollution. The results came to propose intensified agricultural pollution source management in livestock farm and relationship study between land-use spatial distribution and amount of fertilizer application. After investigation of the correlation between groundwater recharge and simulated transport distance of groundwater pollutants, 16 industries were preferentially selected to intensify industrial pollution source management. After assessment of the types of industrial potential pollution and the agricultural land use within 200-meters Zone of Influence, the monitoring pollutants and frequencies were suggested.
This project made a comparison of Taiwan and 4 different countries’management strategies of industrial parks from the aspects of pollution improvement, early warning and prevention and summed up in the problems and needs of management in industrial parks in Taiwan. 3 management goals as the blueprint for future expansions, including promoting pollution early warning, accelerating pollution improvement, and implementing source management, were proposed. Meanwhile, 6 advanced management plans and long-term plans for amendment proposals on the relevant laws and regulations were made. Furthermore, this project has accomplished 3 management works in industrial parks, including having promoted 18 industrial parks with red and orange light pollution indicators through the submission of monitoring plans, collecting administrative appeals and litigation cases to propose improvement on pollution sites with unknown polluter, and collecting quantitative indicators for evaluation the motivation of soil and groundwater management in industrial parks to support government’s future work. In considering the proposed management measures and user feedback, 3 system functions were implemented to extend the soil and groundwater management system of industrial parks, 5 system functions were also implemented based on the proposed management of pollution early warning and prevention, and geographic information system development was also suggested.
