The analysis of the results shows that water resources are not very diversified and are limited to rainwater and groundwater. The factors that explain the bacteriological pollution of these waters are linked to the conditions of transport and storage of water, the environment, the almost total absence of a wastewater management system and the behavior of the population. Chemical pollution is due to chemicals used in socio-economic activities and released into natureenMunicipality of Natitingou, drinking water, physico-chemical and bacteriological parameters, water-borne diseases, modes of contaminationArticle
