Abstract
The origin of the salinity of the Cretaceous and Pliocene-Quaternary aquifers of the Aurès region presents a
challenge for the exploitation and mobilization of groundwater resources. In this region; people can estimate the
quality of groundwater, via samples taken in wells, boreholes and in the springs. Evaporation, endorheic basin
nature, population growth and expansion of irrigated areas are natural and anthropogenic stresses that can lead
to salinization of water bodies. A multidisciplinary approach integrating hydrogeology, hydrochemistry and
multivariate statistical analysis was undertaken to characterize and control the mechanisms of water
mineralization. The main natural geochemical processes involved in the acquisition of the salinization are
related to the interactions between the rocks and the water (dissolution of evaporite minerals), the cation
exchange and evaporation.
