Abstract
This study aims to determine the mechanisms of groundwater mineralization in the departments of Daloa and Zoukougbeu (Central West, Cote d’Ivoire). In order to achieve this, a hydrochemical study was carried out from seventeen (17) water samples (wells and sources) collected in March 2018. It was based on the multivariate statistical analysis techniques: The Principal Component Analysis (PCA) and the Hierarchical Cluster Analysis (HCA) were applied to physicochemical parameters. Thus, the average values of temperature, pH, electrical conductivity, Total Dissolved Solids (TDS) and Turbidity measured in situ in source waters are respectively 27.63°C; 4.81; 84.6 μS / cm; 38.45 mg. L -1 and 40.78 NTU and in well water 27.90°C; 4.78; 81.85μS/cm; 36.61 mg. L -1 and 27.22 NTU. The average concentrations of the major cations Ca 2+ , Mg 2 , Na + and K + of well water are respectively 2.26; 1.01; 4.58; 1.41 mg. L -1 and those of spring waters 2.18; 1.03; 5.50 and 2.07 mg.L -1 . The major anions HCO 3 - , Cl - , SO 4 2- and NO 3 - respectively amount to 8.81; 8.28; 5.33 and 7.67 mg.L -1 for well water and 11.77; 8.5; 5.27 and 8.25 mg.L -1 for spring waters. The PCA results show that three phenomena govern the mineralization of these waters. These are the phenomena of mineralization-residence time of water which is acquired by acid hydrolysis of the host rocks, spatial origin of lower quality of water and the grounds throughfall . These phenomena are confirmed by the Hierarchical Cluster Analysis (HCA). This work is therefore a tool for supporting groundwater management.

Highlights
Groundwater are the main source of drinking water supply due to scarcity and / or exposure to surface water pollution
In the Amacuzac River basin in central Mexico, Eric et al (2016) used multivariate statistical analysis to search for geochemical evolution of groundwater
This study aimed at determine the origin of groundwater mineralization in the areas of Daloa and Zoukougbeu (Central West area of Côte d’Ivoire)
Summary
Groundwater are the main source of drinking water supply due to scarcity and / or exposure to surface water pollution. They are exploited from various works: wells, boreholes, etc. The only alternative to supply population with drinking water, especially in rural areas, is the exploitation of groundwater. It plans to investigate groundwater mineralization mechanisms in the departments of Daloa and Zoukougbeu, using multivariate statistical analysis tools such as Principal Component Analysis (PCA) and Hierarchical Cluster Analysis (HCA). Study Area: The study area includes the departments of Daloa and Zoukougbeu, located in Côte d'Ivoire’s central west. There are two types of aquifers: the aquifer of regolith and the aquifers of cracks
