This study aimed at using of physical, chemical and bacteriological parameters in evaluating the quality of water drinking by choosing four sampling stations: (St.1- Inlet of Abu-Shawi water pumping station, St.2- outlet of Abu-Shawi water pumping station, St.3-Inlet of Al-Abaraa water pumping station and St.4- outlet of Al-Abaraa water pumping station) in the Euphrates River (Shatt Al-Mudaina) in Al-Mudaina city. Samples collected monthly for each station from January to June 2017. The measured parameters were ranged each for (water temperature 11.1-30.2, pH 7.0-8.1, TDS 942.4-2155.7mg/l, total hardness 597.5-1052.3(mg CaCO3/l). Other chemical parameters like chloride ranged from 45.4-185.4 mg/l and dissolved oxygen (DO) ranged between (4.9-11.6) ppm. The results of bacterial tests shows that a total coliform bacteria which is Low fecal contamination levels in the outlet of both drinking water pumping stations, in contrast fecal contamination levels are high in water samples at the inlet of both drinking water pumping stations.
