To effectively manage and utilize groundwater resources and ensure the safety of groundwater sources, various government branches in Taiwan conducted separate investigations and monitoring of hydrogeology, water levels, and water quality, resulting in a lack of integrated thinking in overall management among the branches over the long term. In order to improve the integration of groundwater data and assist the Environmental Protection Administration (EPA) in managing groundwater pollution through system tools, the project aims to establish a Groundwater Information Integration Platform, developing databases and functionalities based on the data of various government branches, and achieve the goal of sustainable management of groundwater. The project examined the information system websites established by domestic and foreign groundwater management agencies, collecting a total of 26 datasets from 8 domestic agencies, and completed the Groundwater Information Integration Platform. The system includes a dynamic monitoring dashboard, data management center, geographic information system, issue-based management, regulatory regions, system management, and other functions. The content of each dataset is integrated into the system platform, and real-time monitoring well and water quality data can be presented visually or as images through the dashboard. Combined with the spatial data query, layer stacking, and environmental analysis functions of the geographic information system, the platform provides decision analysis for groundwater management and integrates information for reference on recent concerns about arsenic and ammonia nitrogen pollution through the issue-based management function. Finally, a system operation manual is compiled based on the end result of platform construction as a reference for business units to apply, and effectively implement monthly system security vulnerability scanning, putting information security maintenance and management in place. Based on the above achievements, the project has established the Groundwater Information Integration Platform by collecting data across multiple agencies and building a database to integrate and apply groundwater data. In the future, it is recommended to continue collecting data from relevant agencies and improving the establishment of groundwater data. In addition, with the assistance of information systems such as aquifer analysis or numerical analysis of groundwater trends, the platform can help manage groundwater pollution and promote related works.
