Rivers of Bangladesh play important role for socioeconomic development as well as balancing ecosystem. Unfortunately, Rivers especially in Dhaka city are being significantly polluting by industrial effluents discharge, solid wastes disposal, and connection of urban sewage. These effluents are containing different hazardous chemicals such as chromium, aluminum, sulphur, lead, salts etc. which have been affecting these River water quality severely. This study is aimed to assess the present status of water quality of Balu River in terms of heavy metals contamination. It is found the average pH in the water of Balu River was 7.76 and Electric Conductivity (EC) ranged from 910 to 1082 μS/cm. Besides, the study found the average Fe, Pb, Cd and Cr concentration were 950, 7.6, 0.56, and 200µg/L, respectively which representing the higher than the WHO and Bangladesh standards. Therefore, it is important to manage the Balu river water quality.
