HYDROCHIMIE DES EAUX SOUTERRAINES DE LA RÉGION D’ADIAKÉ (SUD-EST CÔTIER DE LA CÔTE D’IVOIRE)
Journal Title: Larhyss Journal - Year 2014, Vol 17, Issue 17
Abstract
The aim of this study is to evaluate the physicochemical quality of groundwater and explain phenomenon at the origin to the mineralization of these waters. Methodology based on physicochemical analyses of 26 samples of groundwater. Descriptive analyses of physicochemical parameters show that waters are acid and in the whole very low mineral content. Phosphates, silica and iron contents sometimes have very high levels in the water; above the WHO standard for drinking water. Piper diagram show that groundwater are chlorinated about 89% that above 80% chlorinated sodi-potassium. The Normalized Principal Components Analysis (NPCA) method has enabled to highlight two big phenomena in acquisition of the mineralization of waters. The main phenomenon of production of ions in water is the contact water-rock (the mineralization residence time). The second phenomenon is superficial contributions bound to water inputs through superficial infiltrations and saline and briny waters intrusion in the aquifer. The cluster analysis has enabled to identify four major clusters based chemical composition. The groundwater resources in the region of Adiaké have a good physicochemical quality but need in certain cases a specific treatment before supply.
