In order to improve water quality of Taiwan river and ensure people’s health, Taiwan EPA follows the Water Pollution Control Act to make Total Mass Daily Loads(TMDL) as the main strategy of water quality management in the future. The target of this project is to collect information of TMDL and water quality standard on international, and develop the process of Taiwan TMDL and complete the draft of TMDL in Dahan river.
This project has collected and analyzed the TMDL implemented experience of USA, Japan, Korea, to develop the standard process of Taiwan TMDL. Including identifying candidates for TMDL development, quantifying the allowable pollutant load, allocating waste load, implementation and monitoring. The water type has been classified to four categories, which result are permit standard raising, pollution reducing, environmental investigating and regular monitoring. In addition, we choose the segment between Ganyuan bridge and Fuzhou bridge in Dahan river as an example of TMDL segment and BOD is the control target. We analyzed the allowable pollutant load of the segment, and compiled existing pollution control measures to determine the wasteload allocation. At last we finished the draft of Dahan river TMDL implementation plan, which is a reference materials of TMDL implementation plans for the official authorities in the future.
Besides, we had held several conferences and meetings to collect the opinions from experts in different region, which can complete the process we develop in the project. In the other hand we have established a GIS with pollutant management model as a tool for implementing TMDL in Taiwan.
