| summary |
The objectives of this paper are to review the status of Klang River Basin and to investigate the most significant pollutant using chemometric techniques. The extraction of secondary physico-chemical water quality data by Department of Environment, Malaysia from 2003 to 2007 were taken. Principal Component Analysis (PCA) used to identify the significant water quality parameters and Abso-lute Principal Component Scores-Multiple Linear Regression (APCS-MLR) was applied to evaluate which pollution source contributed the most significant from the other factors. Then, Hierarchical Agglomerative Cluster Analysis (HACA) was used to find which monitor-ing station of Klang River provided the most significant pollutant. The result shows 9 PCs (75% of the total variance) which extracted from PCA. APCS-MLR model revealed anthropogenic activities which NH3-N as the main parameter is the most significant in Klang River. Based on HACA specified 1K16 has the highest amount of NH3-N concentration in Klang River. Therefore, the utilization of envirometric techniques achieved the research objectives which will beneficial for present and future river water quality management.
