Access to clean water and sanitation is essential for health. Its contamination is the main source of water-borne diseases such as typhoid fever and gastroenteritis, intestinal parasites, lead poisoning, cyanosis, fluorosis and diarrhoeal diseases in large proportion. In Benin, there is low coverage of the drinking water supply network (AEP) in rural and semi-urban areas. Drilling wells and boreholes are used by the majority of the population in uncovered areas for drinking water supplies. The lack of maintenance and the failure to respect the rules of hygiene with regard to these waters lead to their contamination. The purpose of this study is to assess the microbiological quality of well and borehole water in the municipality of Sèmè-Podji. A field survey has been carried out on the sources of pollution of these waters, the treatments which are carried out on the water before its consumption, the storage mode, the frequency and the mode of cleaning of the storage tanks on these waters. A total of 46 water samples, including 24 from wells and 22 from boreholes, were collected and analyzed for their microbiological quality using standardized methods at the Water and Food Quality Control Laboratory, affiliated to the DNSP and located in Xwlacodji. The analytical results showed a contamination of 77.65% by thermotolerant coliforms, 45.83% by E. coli, and 77.24% by Enterococci. As for common germs, 100% of the water analyzes were positive. Statistically, there is no significant difference between the microbial loads recorded in these waters, regardless of the arrangements made, from one district to another for thermotolerant coliforms, E. packages and Enterococci. As for common germs, a significant difference was observed between the waters of wells meeting the sanitation standards and the waters of wells not meeting these standards, but there are no more common germs in the waters of drillings not meeting the sanitation standards than in those of drillings meeting this safety perimeter. Water is therefore a potential source of water-borne disease epidemics, which must be addressed before water can be consumed in order to address the threat to public health.
