The present study deals with the water quality of Achankovil River, which enriches the Pathanamthitta district of Kerala state. It joins with the Pamba River at Veeyapuram, in the Alappuzha district of Kerala. The physico chemical parameters like Temperature, pH, Conductivity, Turbidity, Dissolved oxygen, Biological Oxygen Demand, Salinity, Nitrate, Nitrite, Phosphate and Silicate were analyzed. The physico chemical characteristic of Achankovil River was found to be highly fluctuated between the thirteen sampling stations selected during the present investigation. The study revealed that the station Attuva showed highest pollution during premonsoon season. The parameters such as salinity, total dissolved solids and conductivity shown increase in concentration towards the downstream stretches of the river. Though, the quality of water is deprived in majority of the sampling stations towards the downstream indicates the severity of pollution in the river.
