The Kuantan River was selected for this study as a continuous monitoring of the water quality due to the rapid and rapid economic developments or activities throughout the river as it is a tourist and water source for the local community. The objectives of this study are to determine the water quality based classification on the multiple of parameters in the surface water along the Kuantan River, identify the most significant parameters in discriminating the spatial pattern of water quality in the study area, and to classify the source apportionment of the water pollution in the area. This research is about the water quality assessment at 12 stations located along the Kuantan River. The parameters involved in this study are BOD, COD, DO, pH, TSS, TDS, AN, NN, EC, turbidity, salinity and heavy metal elements such as Pb, As, Al, Be, Cd, Co, Cd, Cr, Fe, Mg, Mn, Ni, Se, Ag, Sr, TI, V and Zn. All parameters involved were tested in-situ except COD and heavy metals which were tested in the laboratory and all the data obtained were analyzed through environmetric techniques such as principal component analysis (PCA), hierarchical agglomerative cluster analysis (HACA) and discriminant analysis (DA). There are four clusters configured at the Kuantan River after PCA and HACA exploited whereby S1, S2, S3, S4, S5 considered as clean area (CA), S6 and S7 as low polluted area (LPA), S8, S9 and S10 as medium polluted area (MPA), meanwhile S11 and S12 considered as a high polluted area (HPA).

summary The rapid development of urbanization in the Kuantan area, business activities, bauxite stockpiling, sand mining, husbandry and agricultural activities around the river area have the potential to affect the quality of the water in Sungai Kuantan especially against increased heavy metal pollution. The Kuantan River was selected for this study as a continuous monitoring of the water quality due to the rapid and rapid economic developments or activities throughout the river as it is a tourist and water source for the local community. The objectives of this study are to determine the water quality based classification on the multiple of parameters in the surface water along the Kuantan River, identify the most significant parameters in discriminating the spatial pattern of water quality in the study area, and to classify the source apportionment of the water pollution in the area.
