Water has always been an important survival medium for all the living organisms. But the increasing population has resulted into the industrialization, urbanization, constructions, etc., due to which the limited freshwater resources are threatened with pollution. Assessment of Water Quality Index (WQI) is one of the best tool to calculate the pollution status of the waterbody. Hence, the present study was undertaken to calculate the WQI of Annapurna River in Devgad taluka of district Sindhudurg. Annapurna River is the main source of municipal water supply. Water Quality Index in the present study was determined on the basis of physico-chemical parameters like pH, Total Alkalinity, Total Hardness, Chlorides, Dissolved Oxygen and Biological Oxygen Demand. Key words: Water Quality Index, Annapurna River, Pollution, Sindhudurg. REFERENCES APHA (1992). Standard method for the Examination of water and waste water. APHA AWWA, WPET Washington DC, U. S.
