The present study reports some physicochemical characteristics of the surface water of some ponds in and around Santiniketan. Determination of physical (pH, electrical conductivity and alkalinity) and chemical (sodium, potassium, chlorinity, salinity, free CO2 and COD) parameters were done to determine the surface water quality. The study revealed huge variations in the physico-chemical parameters of water in different ponds. The values of the parameters ranged from pH 5.8 to 8.5, electrical conductivity 1.174 to 712.5 μmhos cm−1, alkalinity 39.4 to 391.2 ppm bicarbonates, Na+ 1.7 to 8.6 ppm, K+ 0.29 to 16.5 ppm, chlorides 55.44 to 443.11 ppm, free CO2 4.75 to 26.14 ppm and COD 2.7 to 52.3 ppm. Correlation analysis indicated high significant relationship (P<0.001, P<0.01) and also significant negative relationship (P<0.05) among the parameters. Churamani was the most polluted among all the ponds.
