The current study was conducted to find out the effect of the discharge of a sewage treatment project on the water quality of the Euphrates River. Samples were collected from wastewater stations (water entering the station, treated water or leaving the station) and river water during the winter and summer seasons from six stations. The study includes three aspects, the first aspect measures the physical properties, which include (temperature, turbidity, electrical conductivity, total suspended solids). The second aspect is concerned with the measurement of chemical properties, which includes (pH, sulfate, chloride, phosphate, total hardness, and total basicity). The third aspect is the measurement of the vital properties, which is represented by (the vital requirement for oxygen, oils and fats). As the results were compared with the Iraqi specifications and the limits of the World Health Organization, and it was found that the turbidity and electrical conductivity exceeded the permissible limit, while the temperature and suspended solids were within the Iraqi specifications. The sulfates and the total hardness were higher than the permissible limit, while the rest of the chemical properties were within the Iraqi specifications, and the vital properties exceeded the limits of the World Health Organization and the Iraqi specifications.
