In the present study an attempt has been made on seasonal variation in physico-chemical status of water quality of Surajkund at Deo, Aurangabad (Bihar). The study was carried out for a period of two years from January, 2014 to December,2014. An average value of atmospheric temperature was recorded to be 26.51�10.16�C, water temperature 22.067�9.05�C, pH 7.045�0.307, conductivity 986.24�124.97 ?mho/cm, dissolved oxygen 6.665�1.05 mg/l, biochemical oxygen demand 3.83�1.25 mg/l, nitrate 1.234�0.23 mg/l, total alkalinity 235.23�24.50 mg/l, chloride 13.48�2.21 mg/l, hardness 194.025�43.05 mg/l, total dissolved solid 588.14�60.51 mg/l and phosphate 0.2925�0.06 mg/l in this study. Statistical analysis inferred that air temperature and water temperature is negatively correlated to pH, dissolved oxygen and phosphate but positively to conductivity, biochemical oxygen demand, nitrate, total alkalinity, chloride, hardness and total dissolved solid. On the other hand, pH showed negative correlation to biochemical oxygen demand, total alkalinity, chloride, hardness and total dissolved solid but positive correlation to conductivity, dissolved oxygen, nitrate and phosphate. Dissolved oxygen is also negatively correlated to biochemical oxygen demand, nitrate, total alkalinity, chloride, hardness and total dissolved solid but positively to phosphate. The analysis will help in understanding the present status of the water body, biodiversity and occurrence of phytoplankton in this system and also assessment of precautionary measures.
