EVALUATION OF THE CHEMICAL AND BACTERIOLOGICAL PARAMETERS OF WELL AND BOREHOLE WATERS IN THE CITY OF NATITINGOU IN THE NORTH WEST OF BENIN

Abstract

The general objective of this research is to study the physico-chemical and bacteriological quality of the water supply sources in the Municipality of Natitingou.The methodological approach adopted revolves around the collection of data on sources of drinking water supply, water sampling, socio-anthropogenic data. 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 nature
