Water quality data of selected wells including pH, EC, TDS and eight other parameters were analyzed by Chemistry, AQQA and SPSS software for processing and interpretation which were evaluated to determine the quality of samples for drinking, agricultural and industrial use. Scholer diagram was used to assess water quality in drinking water. For the determination of water quality for irrigation and industry purposes, the Wilcox diagram and Lange index are used, respectively. According to the Schuler diagram, the water samples of the area indicate a range between good and acceptable waters, indicating the favorable water quality of the area for drinking purposes. Also, according to the Wilcox diagram, the samples in the area indicate two categories including good and average water quality. Among the selected samples, W12 was of good quality and the others were of medium quality. Furthermore, collected samples from W8, W9, W10 and W12 wells could be used for industrial purposes, however, the sample of W6 was scaly. Samples taken from the area are mainly classified as very hard in the total hardness (TH) category which causes consumer dissatisfaction. The samples of the Bonab area were all corrosive due to the low thickness of the Bonab aquifer compared to the Malekan aquifer. Thus, the corrosive properties of the Bonab samples cause water pert and health problems.
