Hashtrood region is located in the southwest of East Azerbaijan province. The main source of drinking water through underground water supply residents there. In order to evaluate groundwater quality, water resources, including 9 throat of deep wells to a depth of 70 to 90 meters in two periods (wet and dry) in compliance with the required standards were sampled for chemical analysis were transferred to specialized laboratories. Data obtained from this evaluation for the purpose of processing and interpretation of the sign were to Rock Works and Geochemistry software’s. In this research, piper diagrams have been used to determine the type and geochemical facies of groundwater. To study and evaluate water for industrial use, the Langelier index has been used in which the criterion of water scaled and corrosive is considered. According to Schuler diagram, the water samples of this area are in the acceptable water range, which indicates that the water quality of the area is desirable for drinking purposes.The water quality of the area for industrial use is in the corrosive category in most samples .Samples of groundwater from Hashtrood city has high hardness ,which is usually influenced by the deceleration of Ca and Mg that there is often bicarbonate ion and chloride sulfate in the water.The corrosive nature of the water in the area leads to the pert of water in the urban supply system, which will cause health problems and material damage
