Assessment, risk, supply water, quality


In order to determine the water quality of Khulna City Corporation, the ground (198-323 m depth; at Nirala, Sonadanga, Khalishpur, Mujgunni, Tutpara, Ferighat and Rupsa) and surface water (at Hadispark) from production well and from the tap of corresponding household (500 meter away from production well) were collected from different locations of Khulna City Corporation and their different physico-chemical properties viz., color, odor, temperature, turbidity, pH, Electrical Conductivity, Total Dissolved Solids, Dissolved Oxygen, total hardness, Chloride and Iron content and coliform count (number/100 ml; both from faecal and nonfaecal origin) were measured. Most of the water samples were found alkaline (pH>7). in most cases from production well to households the pH, Turbidity and total hardness increases whereas EC value, TDS, chloride and iron content decreases. all the observed values are within the permissible limits of Bangladesh and WHO standards for potable purpose but two exceptional cases were found for turbidity 7 JTU at Sonadanga and chloride content 351 ppm at Ferighat. it was observed that production well water at Nirala, Sonadanga and Hadispark contaminated with coliform were 23, 23, and >4800 respectively both from faecal and nonfaecal origin, but at Khalishpur, Mujgunni and Rupsa were free from coliform. water of corresponding households at Nirala, Rupsa and Hadispark had the coliform 09/100 ml, all from faecal origin and the total coliform at Nirala, Sonadanga, Rupsa and Hadispark were 23, 93, 23 and 460 respectively. So it is evident that the supply water at Nirala, Sonadanga, Rupsa and Hadispark does not meet the potable standard.
