The present work was carried out on fifty water samples collected from Zian and Qalabshu during May 2010. Analysis carried out on the selected ten drainage and four subsoil water samples represent the water resources of the study area. The aim of the present work is to suggest the best and scientific method of utilization and conservation of soil and water for the future development in the area. The results showed that samples of El-Nil canal fall in high saline water class. Though such water is permissible for irrigation, it may cause a harmful effect on crops. It may be suitable for plants of moderate tolerance. Samples of El-Sokar factory canal at the front of the factory gate, rejection area of drain-2-station and suction area of drain-2- station, El-Gamaiat canal and subsoil-1, fall in very high saline class which is of doubtful quality for irrigation. Samples of El-Sokar factory canal (1 km away from the factory gate), immersed area of water, ElMoheet drain and subsoil samples, fall in the excessive saline water class which is of unsuitable quality for irrigation. To avoid the serious problem of salinity, the subsoil water was lowered either horizontally by relatively deep surface drains or vertically dewatering from the wells.
