AbstractThe natural water availabilities must exist in adequate quantities, even in the arid regions and in the disinherited regions, so that their distribution and their use don't present any particular difficulties (Bouchkima, 2003). In the Souf valley, the urban development, the important increase in population and extension of the agriculture lands required increase of drinking waters. To face the increasing needs of domestic water, the drillings are reaching the deep groundwater (Continental Intercalary, CI, and the Complex Terminal, CT) have been achieved. The intensive exploitation of groundwater resources, the leakages of the distribution networks of drinking waters, the lack of the drainage of the sewage, the absence of outlet, the throwing out of water discharges in groundwater table and the inadequate of drainage of the irrigation waters create the groundwater rise in the Souf valley. The main objective of our contribution is to present the diverse inconvenients which characterize the overexploitation of the groundwater and the negative impacts of the groundwater rise phenomenon on the environment in the Souf valley (the Algerian desert). In front of this problem, some solutions have been proposed and discussed.
