Abstract: Pampa River is the third longest river in the South Indian state of Kerala. The river is one of the most stressed rivers in Kerala.Water quality of Chengannur segment of Pampa River was determined based on Chemical parameters such as BOD, pH, Dissolved Oxygen, Nitate and Phosphate followed by water quality index. Three study sites were selected. Mean with standard deviation were taken. Two way ANOVA was conducted. The water quality index (WqI) was calculated. The quality index during premonsoon and summer was 81 and 59 for BOD, 68 and 80 for p H, 5 and 96 for Dissolved Oxygen, 99 and 96 for Nitrate, 31 and 43 for phosphate. The study shows that water in the Chengannur segment of Pampa river is of moderate quality.
