摘要：Water quality is very essentialto human health. And, Groundwater quality assessment is necessaryto guaranteesustainable safe use of water. Hence, in the region of study of Oum Azza, the presence the waste center treatmentit could alter the quality of groundwater. In the present paper, hydrochemical, geochemical and multivariate statistical were used to assess the impact of waste treatment center Oum Azza on groundwater quality. Q-mode hierarchical cluster analysis (HCA) based on major ion contents and hydrochemical facies; defined three main chemical water types. The first, group 1, has low salinity (mean EC=813μS/cm) and abundance orders Ca2+> Na+>Mg2+>K+and HCO3->Cl->NO3->. With increased water-rock interaction, waters in group 2and 3 become more saline, changing composition towards Cl -Ca-Mg and HCO3-- Na+-Mg2+.The principal compo nent analysis (PCA) revealed, onpart of the existence of phenomena governing groundwater mineralization particular, the water-rock interaction.And another part a tendency to nitrogen pollution localized at collected well water. These results contribute to a better understanding of the hydrochemical properties of groundwater in the area of study
