Evaluation of Underground Waters Hydrochemicalfacies in Daoukro Area (Cote dIvoire)

The water, in relation with encountered lands, is loaded with various elements that will influence its quality and its mineralogical composition. This study aims to evaluate the hydrochemical facies and the origin of the mineralization of groundwater in the Daoukro region. The methodology adopted consisted in determining the various hydrochemical facies using the Pipper diagram. Statistical analyses were carried out to determine the origin of the Daoukro groundwater mineralization. The hydrochemical classification of water through the Piper diagram showed waters characterized by bicarbonate calcium facies with a slight tendency to migrate to the chloride-calcium facies. Normalized component analysis shows a positive correlation between conductivity, calcium, magnesium and bicarbonate. These correlations indicate a phenomenon of the dissolution of rocks and the hydrolysis of minerals related to remain time of rocks in the water.
