Abstract

Water quality study of the selected physico-chemical and microbial parameters of the Langat River were carried out to determine and classified their values. Sampling was carried out twice; first on 9 June 2011 and the second was on 22 February 2012. The sampling site consist of seven stations; five stations representing for Langat River branches while two stations are located in Langat River. The in-situ measurements are: dissolved oxygen, electrical conductivity, total dissolved solids, pH and temperature were performed using YSI 556 multiparameter, while the laboratory analysis were based on HACH and APHA methods. Result shows; temperature (23.4 � 27.7�C), pH (5.07 to 6.15), EC (29.3 � 61.5 µS/cm), TDS (19.7 � 47.0 mg/L), DO (3.68 � 5.72 mg/L), BOD (1.29 � 3.76 mg/L), COD (13.5 � 77.85 mg/L), TSS (9.5 � 86.5 mg/L), NH3N (0.15 � 0.79 mg/L), NO3 (0.8 � 4.9 mg/L), PO4 3� (0.15 � 0.7 mg/L), SO4 2- (0.5 � 12.5 mg/L) and biological parameters of faecal coliform (2.58 � 104 � 4.74 �106 cfu/100 ml). Based on water quality index and the National Water Quality Standards classifications, they belong to the class I, II, III and V. One-way ANOVA for repeated measures and Pearson correlation test been used. The overall results showed the selected rivers in upstream of Langat River were classified as moderately polluted. © 2015, Malaysian Society of Analytical Sciences. All rights reserved.
