|a The north-eastern part of the eastern great erg (low Sahara), where a Saharan (hyper arid) climate that reigns over the entire region of the Algerian Su. The latter, is based on the most important water resources of the world: the Intercalary Continental (CI), contained in the formations of the lower Cretaceous (pierced in the Albian layer) hence its name: "Albian nappe". It covers 600000 square kilometers. Surmounted by the reservoirs of the Terminal Complex (CT), (first and second mio-Pliocene aquifer, Sénonien-Eocene limestone aquifer) which covers an area of 35000 km2. and by the water table most in demand for irrigation needs (the water table), contained in Quaternary sand and clay alluvial formations. The chemical quality of these waters is a major problem, such as salinity, strong mineralization and the concentration of some elements that exceed the standards recommended by WHO. This work is a contribution to the presentation and comparison of the hydro geochemical evolution of water aquifer levels between various regions of the lower Sahara, by the search for a relationship between the chemical composition of water and the lithological nature of aquifers in gener
