The present study on assessment of water quality in Chite river and its selected tributaries was conducted for a period of one year during 2019 - 2020. An Overall Index of Pollution (OIP) was used to assess the water quality to determine the water quality index. Water samples were collected for three seasons, viz., pre-monsoon, monsoon and postmonsoon. Various physical and chemical parameters like pH, Electrical Conductivity, Total Dissolved Solids, Turbidity, Dissolved Oxygen, Nitrate, Chloride and Fluoride were analyzed for six selected sites. The observed OIP values for different sites reveals that water quality of Chite River and the selected tributaries varied from ‘slightly polluted’ to ‘polluted’. Therefore, it was concluded that the surface water quality of Chite and its tributaries within the urbanized area had high OIP score, and hence required urgent management for the maintenance of ecological sustainability and safety.
