Abstract: This study was conducted to assess various physico-chemical parameters of water quality of Bhairab River in the Noapara Region, Jashore, Bangladesh and to comprehend the present pollution scenario of that river in the studied region. Samples were collected from three different points during the study period (October 2015 to August 2016) and analysed for various water quality parameters. The mean values of temperature, pH, salinity, TDS, EC, BOD, COD, DO and turbidity were found to be 29°C, 8.4, 395.8 mg/l, 570 mg/l, 776.3 μS/cm, 2.14 mg/l, 12.44 mg/l, 4.86 mg/l and 554.4 mg/l, respectively. Water quality index was determined and found to be much higher than the suitability limit of water for drinking. Thus, the study showed that the water quality was not suitable for drinking or cooking purposes rather the river water could be used for irrigation, navigation and recreational purposes.

Keywords: physico-chemical parameters; Bhairab River; pollution; Noapara; Bangladesh.
