Physico-chemical analysis of different water samples reveals a significant change of various elements levels relative to international and Algerian standards of water potability. Valley’s water table are characterized by high mineralization making them unfit for human consumption. The study spatial variation of each element shows a concentration gradient of water from upstream to downstream.frwater table, spatial variation, physico-chemical, standard, Sebsebeaux phréatique, variation spatiale, physico-chimique, normes, sebseb
