Abstract: Achencovil River with a length of 128 kms is a major river of Kerala. Physico-chemical parameters, microbiological and pollution indicators of the River Achencovil, Kerala, India was determined during summer season. The physico-chemical parameters like Turbidity, Temperature, pH, Total Dissolved solids (TDS), Conductivity, Dissolved Oxygen, Biological Oxygen Demand, Nitrate, Phosphate, microbiological analysis like Total Coliform Count were studied and analyzed during summer season, 2012 using standard procedures. The water samples were collected from three different sites of mid stream Vettiyar segment during summer season. All most all parameters showed significant (p<0.05) variation between sites and was determined by analysis of variance (Anova). Water Quality Index and microbiological characteristic like Total Coliform Count (TC) were also analyzed. The aqatic insects ordrer like Odonata, Hemiptera were obtained during the study period. Overall water quality index of Vettiyar segment in river Achenkovil during summer season was 59.
