River Coleroon ,Physico - Chemical parameters ,Hardness ,Desirable limits ,

The River Coleroon is the drainage carrier of Cauvery, branching out near Upper Anaicut. Normally, the entire flood waters of Cauvery, surplus from Mettur dam are being diverted to Upper Anaicut and Coleroon directly and also through Grand Anaicut, Tamil Nadu, India. For the present research work, four sampling sites were identified and river water quality was analysed on a monthly basis over a period of 13 months. The present study deals with the changes in physicochemical parameters, such as air, water, temperature, pH, Dissolved solids, Electrical Conductivity, Hardness, Calcium, Magnesium, Sulphate and Phosphate. These parameters were observed from June 2014 to June 2015. The results suggested that water quality of the Coleroon River is in desirable limits of WHO.
