Abstract
This study was conducted to evaluate well water and lower Zap stream water quality for irrigation and other uses Eleven representation wells were chosen besides samples were taken from the lower Zap. Water samples were taken during two periods 10/9/2009 and 12/4/2010. The results indicated that the classes of water varies between (C3-S1) to C1-S3 according to the W.S salinity laboratory classification, besides the dominated cations and anions were sodium, calcium, chloride, and sulphate, therefore most of these wells may cause problems for soil and plant and this water should be used under special management , The result of this study indicated that the water of these wells can not be used for domestic and industrial purpose because of high (TDS) except of the well No.(11) . On the other hand the quality of lower Zap water was better as compared to the other wells water in the same region.
