Taiwan''s rapid economic growth in past decades leads to severe environment pollution. In a variety of environmental pollution, water pollution is closely related to our lives and have drawn great attention from the public. For this reason, this research through descriptive analysis, regression analysis, factor analysis and cross analysis methods with RPI and WQI water quality assessment model to analysis water quality of Chong-Kong River. It was found that livestock, chemical, paper, petroleum industrial discharge and domestic wastewaters have seriously polluted the Chong-Kong River. Compared to RPI model, the WQI model was found to be more suitable when assessing the water quality for Chong-Kong River Using skewness and kurtosis, the unusual events, the discharge patterns, such high concentration of low frequency discharge, regular high concentration discharge, and etc., can be determined. By such analysis, the monitored water quality can be further examined and provide more information for development of water quality management policy.
