Parameters studied were, total hardness, sulphate, chloride, sodium, calcium, magnesium, turbidity, and Electric conductivity. Average values for all measured chemical parameters were exceeded the permissible limits for safe drinking water. The results show that the WQI values of water treatment plants in Basrah Governorate ranged between 26 and 89. For the three years of study 2012-2014 most of water treatment plants within Basrah Governorate were either poor or marginal, few were fair and good.
