Abstract

The study was conducted to assessment of two drinking water treatment plants in Baghdad City, Iraq from December 2016 to July 2017. Three sites for each plant were selected which represent the sedimentation basin, filtration basin and final stages after chlorination. Seventeen physicochemical parameters of water quality were analyzed in this assessment. These parameters were temperature, turbidity, electrical conductivity, pH, dissolved oxygen, biological demand oxygen, total dissolved solids, total hardness, nitrate, phosphate, calcium, magnesium, residual chlorine and heavy metals (lead, cadmium, Nikel and Chromium). In addition to four bacterial indicators of drinking water pollution (APC, Total Coliform, Fecal Coliform and Salmonella spp). The results showed variation in drinking water quality parameter values in both treatment plants. Moreover, the presence of numbers of bacteria greater than permissible limit, indicating a deficiency in the purification process.
