Abstract : The Miocene-Pliocene aquifer system in northern Saudi Arabia represents an important groundwater resource. Groundwater occurs in multilayer water-bearing horizons of sandstone, chalk and marl. It moves under an average hydraulic gradient of 0.002 towards Sabkhat Hazouza. The average transmissivity is 20-170 m?2/day and the average storativity varies between 0.11 × 10?2 to 3.7 × 10?2. The total mineralization of groundwater ranges from 430 to 6000 mg/l. The main water types is NaCl, with Ca-Mg-SO4 as next in abundance. The main hydrochemical processes responsible for the water quality variations are ion-exchange, dissolution or mixing and limited reverse ion-exchange. The spatial distribution of the major ions, dissolved silica and iron are independent of the Sabkhat Hazouza. The salt effects of which seem to be restricted to the few meters close to the ground surface.
