Abstract:
Four central rivers of Bangladesh were selected for this research. The name of the rivers is Buriganga, Dhaleshwari, Shitalakshya and Meghna. The Electrical Conductivity (EC), pH, Total Dissolved Solid (TDS), and Salinity of the four river waters were evaluated. The EC values of the water of the Buriganga, Dhaleshwari, Shitalakshya and Meghna rivers were found to be 366.0, 299.2, 290.4 and 130.8 µS/cm respectively. Similarly, the pH values of 7.67, 7.38, 7.30 and 7.18 were found for the river waters of the Buriganga, Dhaleshwari, Shitalakshya and Meghna respectively. The EC and pH values were found higher for the Buriganga river water than that of the other three river waters. The TDS and salinity of the Buriganga river water were found 180 mg/l and 0.72% respectively. On the other hand, the TDS and salinity of the Meghna river water was found lower compared to the other three rivers. From this research, this is clear that the quality of the Meghna river water is much better than the river waters of the Buriganga, Dhaleshwari, and Shitalakshya. The quality of the Buriganga river water was found inferior. Dhaka city, the capital of Bangladesh, stands on the bank of the Buriganga river, and as a result a large number of unban waste goes directly to the river Buriganga. As a result, the water of Buriganga became polluted. This investigation proved that the Meghna river water quality is still much better and suitable for many applications.
