Abstract

The study was conducted to investigate the physicochemical parameters of the Jhenai River during the period from February-April 2018. The water samples were collected from three different sampling stations as St-1 (Kalihati), St-2 (Bahala Hat) and St-3 (Hazipur Hat) for analyzing the physicochemical parameters such as temperature, electrical conductivity, total dissolved solids, pH, dissolved oxygen, biochemical oxygen demand and hardness in water. The physicochemical parameters were analyzed in the laboratory of the Department of Environmental Science, Patuakhali Science and Technology University, Patuakhali, Bangladesh, The result of the study showed that the temperature was ranged from 23.7-31.7°C, indicated an increasing rate from February to April. The contents of EC and TDS were varied from 655-698µS/cm and 524-582mg/l, respectively, indicated high ionic concentration in the river water. The contents of DO and BOD of all stations were ranged from 4.2-5.4 and 1.1-1.4mg/l revealed that organic waste pollution, whereas the pH (7.34-7.56) of all stations showed alkaline condition. The hardness contents were ranged from 132.20-143.40mg/l indicated suitable for aquatic environment. The result of the study concluded that the water can be used for various purposes as well as for aquatic organisms. To maintain the river water quality and conserve the aquatic life, proper measures should be taken to prevent the introduction of water pollutants into the river water.
