Abstract
At present, the condition of surface water is much declining and the quality of water is a vital concern for mankind. It is directly linked with human security. Greater part of people is still not aware of it. So, improvement of the condition of surface water is a crying need. Surface water is often physically contaminated due to unhygienic practices. Discharges from various contaminated sources are very common thing in city life which deteriorates the water quality and necessary treatment is required to make water usable. The investigation is based on laboratory tests on water samples obtained from seven Ponds and three Charas of Sylhet City Corporation. The selected parameters for assessing the water quality are PH, Biochemical Oxygen Demand (BOD) and Dissolved Oxygen (DO). The present condition of Ponds and Charas water are not up to the mark and it is declining day by day. Proper initiatives need to take regarding the control of surface water pollution in Sylhet.
