Analysis of Microbiological Quality of Drinking Water in Lalo Commune, Benin (West Africa)

Although drinking water is readily available in Benin, a public health problem arises in terms of its quality. The district of Ahomadégbé in the commune of Lalo is characterized by several artesian wells. Unfortunately, anthropogenic factors negatively affect the drinking water quality in this area. This research aims to analyze the microbiological quality of drinking water in the Ahomadégbé district and to reassess household water treatment methods practiced by the local population. To achieve these goals thirty-five water samples were taken at water collection points, at selected points along the water transportation system and from water storage facilities, and microbiological parameters were measured. The qualitative aspect of the research allowed to approach key interlocutors for in-depth discussions on endogenous techniques for treating water at home.

The analysis of results permitted to note the high degree of microbiological pollution of drinking water in this district, particularly during the water transportation and storage stages where microbiological pollution is above the standards approved by the World Health Organization. Local residents are familiar with several household water treatment methods. However, they remain less effective due to their inappropriate application.

In addition to improving the quality of the drinking water resource itself, it is important to set up interventions relating to water treatment methods in local households.
