The investigation of groundwater quality is one of the most important subjects in the field of groundwater resource. The main purpose of this research is the study of groundwater samples witch have been collected from 12 and 9 pumping wells throughout 1385-1394 years. The samples have been analyzed for major cations (Na, K, Mg and Ca), major anions (Cl, SO4, HCO3 andCO3) and physical parameters such as TDS, TH, Ec and pH. In following, the hydrogeochemical graphs such as Piper diagrams used for water classification. The analysis of results showed the increasing of TDS, TH and EC upper the limit. According to Schoeller and Wilcox diagrams, the water is not suitable for drinking purposes, agricultural and industrial uses. Such results are more helpful to manage the groundwater resource.
