The present study was carried out on characterization of surface water and groundwater reservoirs in Merched village near Raichur city in Karnataka. Surface water samples were collected from different locations of the Merched tank and groundwater samples were collected from the bore wells, hand pumps located at the command area of Merched tank during 2018-2019 in monsoon and post monsoon season. The collected water samples were analyzed for the water quality parameters like pH, EC, TDS, carbonate, bicarbonate, nitrate, phosphate, calcium, magnesium, sodium, BOD, COD, DO and turbidity by using standard methods. The results obtained were compared with drinking and irrigation water quality standards. The results showed that pH (ranges from 7.36 - 8.54) of surface water and ground water were slightly alkaline in nature. The EC and TDS of surface water and ground water were not within the drinking water quality standards. The results obtained for monsoon season, the mean value of BOD (562.31, 977 mg L-1), COD (15270.44, 11138.63 mg L-1), DO (7.72, 7.70 mg L-1) and turbidity (11.20, 11.37 NTU) for surface water and ground water respectively. Similarly result obtained for post monsoon, the mean value of BOD (457.88, 904 mg L-1), COD (7189.69, 9287.38 mg L-1), DO (4.97, 4.93 mg L-1) and turbidity (11.37, 11.20 mg L-1) for surface water and ground water respectively. All the water quality parameters were within the recommended range of irrigation standards except the parameters BOD, COD, DO and turbidity.
