Popis: The Tigris River is the most important source of water in Iraq; however, it suffers from the impact of pollutants that disposal directly into it. In this study, the Water Quality Index (WQI) of 7 of the chemical properties (Cl-, NO3, SO4, COD, BOD5, Ca, Mg) in the Tigris River, Baghdad, Iraq was analyzed to measure the impact of liquid waste discharge in the city of medicine on the river from January to October 2020. Three points were selected as the sample location, the first point was 700 meters before the discharge point, the second point was the discharge point, and the third point was 400 meters after the discharge point. The findings revealed that the concentration of all the measured components at the region where the sanitary discharge point site2 was situated was much higher than that of the location before the sanitary discharge point site1. For example, in January Cl- the concentration at site1 was (350 mg/l) relative to site2 the concentration at (1200 mg/l). In comparison, the concentration of the constituents in the area after the sanitary discharge point site 3 was lower than that of the sanitary discharge point area site2. In addition, Cl- concentration at site3 was (750 mg/l) lower than site2 (1200 mg/l) but still higher than site1 (350 mg/l). The lower concentration at site3 suggests that the water body of the river is being diluted; however, this is not a solution as the causes of pollutants of the river are various. Most of the findings have shown that the permissible cap for the Iraqi standards and the World Health Organization (WHO) for the river maintenance system has been surpassed.
