Abstract: The study area is entirely located within Wadi Dawasir. It is located between latitudes 19o30/ 00// N, 21o 00/ 00// N and longitudes 44o 00/ 00// E, 46o30/ 00// E some 670 Km from Riyadh. Wadi Dawasir area is considered one of the biggest agricultural areas in the Kingdom of Saudi Arabia. Wajid Formation, which comprises the oldest Paleozoic sediments, is encountered in the Wadi Dawasir area both in the outcrop and subsurface. The used water for drinking or irrigation is discharged from Wajid Aquifer. The lower aquiclude is the Basement Complex, which is considered an impermeable unit. The aquiclude consists of the basal shale beds of Khuff Formation in zones where the Wajid Formation is affected by the Pre-Khuff erosion. The study area is found within the arid zone which characterize by a high temperature, high rate of evaporation, low rate of precipitation and low humidity that cause a low recharge of aquifer from outcrop comparing with a high rate of withdrawal from wells. Wajid Aquifer may be considered as a single hydraulic unit with fairly homogeneous lithology.
