The purpose of this project is to evaluate the condition and performance of the present water quality monitoring systems, and to suggest a holistic project to integrate every monitoring procedure. Some suggestions about applications and adjustments toward the present evaluating approaches are provided in this project; the project team makes comparisons of the water quality indexes, statistic data within stated countries by researching data and approaches to water quality monitoring procedures in domestic and overseas system in the countries, such as the USA, Japan, Holland, Singapore, Germany, Australia, and New Zealand. Furthermore, to understand and to review the present domestic water quality monitoring procedures and procedures, the project team interviewed the related project teamities and held two symposiums with a panel of experts. The opinions of these experts are taken as important references to develop the future plan of the water quality monitoring systems.
This project also suggests that central and local governments should mutually provide data and information. Water quality monitoring stations could be classified into two levels - national stations and local stations , in accordance with the reformation of the government organization and the new local divisions of the five major cities in Taiwan. These five major cities should monitor water quality within their own districts first, and then adjust the frequencies of monitoring based on each water quality and water usage data. By doing so, the economic benefits of the present water monitoring procedures could be maximized.
The project team also advises that the existing monitoring processes the process of monitoring water quality and water flux should be combined together to reflect the contaminated condition more precisely. Another highlight of this project is that the project team recommends replacing the current indicators. Carlson's Trophic State Index, which is usually applied to the lakes in temperate area, is considered not suitable for the condition in Taiwanese dams, that is suggested to be replaced with OECD indicator of eutrophication for lake, which is a single indicator that determined by chlorophyll-a. With regard to the index for rivers, the project team suggests to replace the currently used index RPI, with WQI7, proposed by Professor Ching-Gung Wen from National Cheng Kung University in 2008, which is also considered to be able to precisely reflect the contaminated conditions of the rivers in Taiwan.
