Iran is one of the semi-arid areas and shortage of water resources is considered. And identify and manage sources of the most important things.The water quality of Dez River is one of the major concerns of the area and for Dezful city. This study was carried out using evaluation based water sampling and statistics result. A number of 394 samples were analyzed and the concentration of physical and chemical parameters including pH, TDS,EC, total cations and anions were measured.The obtained results were examined and compared based on the analyses consistent with the World Health Organization (WHO) standards. Dez River water quality has been “Perfect” in most cases on the basis of TDS and considering the average sum total of them amounting to 644 mg/l during the mentioned period; indeed only in 2% of the statistical periods the water quality has been determined as Acceptable, while most of the water quality parameters have been within the permissible range of the WHO standards.
