In order to maintain water quality, to build a suitable environment, and to improve national health, Taiwan EPA promotes “Water Quality Improvement and Environmental Management Program” by focusing on water pollution remediation in 11 primary rivers (Tamsui River, Nankan River, Lao-Jie River, Jhuoshuei River, New Huwei River, Beigang River, Ji-Shuei river, Yanshuei River, Er-Jen River, A-Gung-Dian River, and Love River) from 2012 to 2017. 　　The purpose of the project is to monitor the execution and to apply rolling management to the water pollution remediation in 11 primary rivers, including analyzing water quality of the rivers in the past 6 year, tracing the source and effect of the pollution, the status of the execution of remediation, the result of the remediation. And in order to grasp the critical reach of each primary river, the project choose 22 critical water quality observation stations and choose critical water quality item in each primary river. Also, the project apply water quality modeling, remediation strategy development, and making remediation suggestions for EPBs in Taiwan. 　　The content of remediation strategy is waste sewer, waste interception, water quality on site treatment, wastewater utility check and control, animal wastewater reduce(including treat animal wastewater as the material of ferment), and developing the target of remediation management plan for river across Taiwan(reservoir in islands) through 19 meetings and rolling reviews, respectively. 　　Additionally, through promoting the water quality management evaluation, including onsite treatment supervising (total 27 time in 31 sites across 19 cities and counties) and benchmarking target development. The purpose is to urge local governments to maintain their onsite treatment facilities, and encourage local governments to proceed self-management for water quality, respectively. 　　For the purpose of assisting EPA in monitoring its performance in environmental protection, this project collects the result of water quality remediation during 2012 to 2014 and results in 9 artificial wetlands in Taiwan (including basic information, water quality, ecological and public participation), and for public disclosure and attention, the water pollution remediation related website updated every month and 1 site visit activity are also in the scope of project.
