N2  - The aquifer of the alluvial terraces of the Béni Abbès palm grove is subject to a hyperarid climate. The groundwater salinity problem is caused by several human and natural factors, causing serious irrigation problems. Hydrochemical analyses over a 40-year interval show an alarming Spatio-temporal evolution of salinity: the drying up of the Saoura valley due, on the one hand, to the impact of the construction of the Djorf Torba dam, on the other hand to the strong evaporation which reigns, have seriously affected the quality of the waters of the infero-flow. In addition to the diffusion of salinity through the natural drain, the overexploitation of water from the terraces of the Saoura valley and the anarchic proliferation of wells in search of fresh water, intended for the irrigation of the palm grove, lead to a spectacular acceleration of this destructive phenomenon of the entire hydrogeological system of this region. In this work, old and new analysis results are used to make a comparison on the evolution of the aquifer. Such a comparative analysis has the advantage of making it possible to assess certain influences subject to severe natural and anthropogenic constraints on the acquisition of the chemical characteristics of water.
