RESUME L'accès à l'eau potable dans les zones rurales et semi-rurales constitue une préoccupation majeure pour les populations à cause de la qualité de la ressource. L'objectif de cette étude était d'évaluer le degré de pollution des eaux souterraines au Sud de la Côte d'Ivoire. La méthodologie adoptée a consisté à évaluer le niveau de pollution par le suivi de la variation spatiale des teneurs des indicateurs de pollution des eaux consommées. Des tests statistiques ont permis d'avoir l'origine probable des sources de pollution. Les paramètres de pollution les plus menaçants restent le phosphate (PO Mots clés : Eaux souterraines, sels dissous, pollution fécale, Bingerville.

This study aimed at assessing the pollution degree of groundwater resources in southern Côte d'Ivoire. The methodology adopted consisted in assessing the pollution level by monitoring the spatial variation F. KANOHIN Epse OTCHOUMOU et al. / Int. J. Biol. Chem. Sci. 11(5): 2495-2509, 2017 2496 in the water pollution indicators levels. Statistical analyses have led to the probable origin of pollution sources. The most threatening pollution parameters remain phosphate (PO 4 3-) and ammonium (NH 4 + ). The statistical analysis show two major phenomena: the surface pollution represented by the factor 1 and the mineralization factors 2 and 3. Minerals (PO 4 3-, NH4+ and NO 3 -) observed in Factor 1 show that ions that threaten these resources quality would come from human activities. Identification and bacteriological analysis of total fecal coliforms, Streptococci and Clostridium perfringens confirmed these results. These bacteria fecal pollution made the water resources unfit for human consumption.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
