Physicochemical Analysis of Ground Water Quality, Hydrochemical Characterization of the Doukkala Plain, Morocco

Abstract

This study concerns the analysis of the physico-chemical parameters (T°, pH, EC, NO3-, Cl-, PO43-, HCO3-, SO42-, Ca2+, Mg2+, K+ and Na+) of groundwater from the Doukkala, in order to establish its pollution diagnosis. Thus, water samples were taken at 8 stations in January and July.The results show that the wells are characterized by a geochemical facies Chloride and sulphate of calcium and magnesiu and potassium chloride or sodium sulphate. According to Moroccan standards and the values of certain parameters such as temperature, hydrogen potential, conductivity, alkalis, alkaline earth metals, sulphates, chlorides the studied the ground water was classified from good to poor quality (CNS, 1994).
