PHYSICOCHEMICAL TYPOLOGY OF WATERS FROM WEATHERED AQUIFERS IN THE MAN DEPARTMENT, WESTERN COTE DIVOIRE

The hydrogeochemical study conducted in the Man Department (western Cote dIvoire) aims to characterise the physicochemicalquality of well water in relation to the local geological formations. The investigation was carried out on 56 wellsevenly distributed across the department. The physical parameters consideredinclude temperature, pH, turbidity, redox potential, total dissolvedsolids (TDS), and electricalconductivity (EC). The chemical parameters include the major cations and anions. The hydraulic structures are mainlyunderlain by three lithological units: anorthosites, norites, and charnockites, which correspond to heterogeneous biotite-bearinggranitoids and migmatites covering nearly 88% of the study area.
