Abstract :
In recent years, the excessive use of existing water resources and subsequent droughts, have led irrigation water resources quantitatively and qualitatively changes. Water quality is one of the most important determinants for its use in various water uses. Therefore water quality management and monitor are important. In this study, the water resources quality of Siuki area of Torbat-Heydarieh city was investigated according to the water resources chemical analysis used in agricultural sector consist of sugar factory wastewater, refined urban wastewater, Qanat and well (a total of 10 wells with crop use) during 2009-2013 years and Wilcox diagram, permeability index (I), SAR, chorine and sodium percentage and other cations and anions were studied. The results showed that the salinity of the wastewater was equal to 20000 mmhos/cm and in the (C4) class. According to the Wilcox and SAR, most of the samples were in C4S1 and in the middleclass. Based on the results, all of the water resources, both conventional and unconventional of the studied area are suitable for agricultural uses, but for the plant wastewater, more should be taken for agricultural and crop production.
