Geographia Technica, No. 1/2009, pp. 57 - 67 EVOLUTION DU CHIMISME DES EAUX DE L’AQUIFER SUPERFICIEL DE ZAAFRANE (REGION DE LA STEPPE ALGERIENNE)A. Maoui, N. Kherici, F. DerradjiABSTRACT - CHIMISME EVOLUTION OF WATERS IN THE SUPERFICIAL AQUIFER OF ZAAFRANE (ALGERIAN STEPE REGION) - Zaafrane area, a transition zone between Sahara and North, is characterized by a semi arid climate. In order to study the hydrochemistry of waters of the superficial aquifer the interpretation of two periods of chemical data shows the evolution of chloride, sulfate, sodium and potassium. Piezometric map suggests that water is moving from the South East towards North west and agree with the diminution of characteristic rapport r.SO42-/r.Cl-,prove that evaporites originate is from the South .Degradation of water quality can be attribuated to an organic pollution in most cases, linked to direct anthropic pollution in this rural area, favoured by the absence of a sanitation network.
