Abstract:
Background and Objective: In the precarious neighbourhoods of developing countries built on the outskirts of urban centres, about 70% of the population is not connected to the drinking water network and consumes groundwater whose quality is not controlled. This situation is responsible for health disasters that lead to the death of several million people. In this study, sanitation practices, physicochemical and bacteriological quality of groundwater and the potential impact of equipping wells with electric pump were assessed in a precarious neighbourhood in sub-Saharan Africa. Materials and Methods: Questionnaires were administered to 100 households to determine their sanitation practices. The water samples from 12 wells were analyzed for physicochemical and bacteriological evaluations. Results: The solid and liquid wastes are evacuated in nature, watercourses and roads by the local population. The main sanitary facilities are traditional pit latrines and their distance to wells violated the limits of the guidelines. pH, Salinity and turbidity exceed the World Health Organization (WHO) standards within 58.33, 75 and 41.67% of the wells respectively, thus affecting the organoleptic quality of the groundwater. Faecal and total coliforms, faecal streptococci, Salmonella and Vibrio exceeded WHO guidelines in 91.67% of the wells. The presence of an electric pump does not significantly improve groundwater quality. Conclusion: To reduce the prevalence of waterborne diseases in precarious neighbourhoods in developing countries, it is necessary to extend the drinking water distribution network in these neighbourhoods and encourage the population to treat groundwater before consumption.
