Online published on 12 June, 2018. Abstract The present study focus on the assessment of monthly changes in water quality of the Euphrates River from Hindiya Dam to Mishkab regulator Physico-chemical properties of water in Euphrates River were studied throughout six months (January to June)of 2016. The current study included measurements of pH, EC, air and water temperature, total alkalinity, total hardness, Ca, Mg, turbidity, salinity, TDS, TSS, DO, BOD, Na, K, and Chloride in 14 Sites, the Water Quality Index (WQI) was calculated. The results revealed that the averages of pH values of both Sites ranged between (7.39–8.24). Mean while, values of salinity and total hardness were high in Site (8) in which the highest was during January up to 1320 mg/l, whereas, concentrations of other parameters varied during the whole study period. The value of dissolved oxygen, on the other hand, recorded the highest value in Site4 during May reading 12.4 mg/, while the biological oxygen demand recorded the lowest value, 0.3 mg/l., in Site (6) during April. The WQI values obtained were high in February monthcompared to that of other months of the study period. The SAR values varied from 3.2 to 7.4 during study period. The results of percentage sodium in the water body that ranged between (28 to 55) %. Concludes the water quality assessment of Euphrates River shown that the physico-chemical quality of the water was recorded high values in Sites (6, 8, 10). The water quality index determined show that the water of Euphrates River is ‗Unfit‘for drinking and appropriate for irrigation relying on adsorption ratio of sodium and percentage of sodium.
