Water Quality Estimation of the Kum-Ho River by Multivariate Analysis

The water quality of the Kum-Ho River was estimated by multivariate analysis. Results of the analysis were as follow as : 1. The water quality of the Kum-Ho river estimated by the factor scores were generally not different throughout the period of this research. 2. The cumulative proportion to the third principal components was 97.8%. 3. The factor loadings of 14 water quality items studied were over 0.9. The river appeared to be polluted by human activities and the waste water from nearby factories. 4. The flow of Kum-Ho river was closed related to COD(cr) and the factor scores. The run-off loading rate, therefore, could be explained by COD(cr) and factor scores. The run-off loading rate of the lower Kum-Ho river basin showed no significant variation, where the pollutions were mainly contributed by the point soures.
