Recognizing quality of groundwaters as one of the most important and vulnerable sources of water supply in recent decades is a necessary issue. regarding this topic that water purification is sensitive and time consuming, studying quality of groundwater supply is essential. In this research, in order to study chemical compounds of groundwater, 21 observed wells were sampled in  the summer of 2013 year and important parameters of samples were measured and calculated for agricultural and drinking uses. Also Piper diagram was used to determine hydrochemical facies of the groundwater area. The results showed that dominant type of groundwater hydrochemical facies of region was calcium sulfate (Ca-S0₄). According to World Health Organization standard, among wells of region just  H9, L15, O12, and L6C wells was suitable for drinking use and these wells in terms of sodium hazard and change of soil structure for agriculture use, had a good to admissible situation . Also groundwater of that region had moderate permeability index; therefore, it should be used for soil irrigation with sufficient permeability and cultivation of salt tolerant plants.
