ABSTRACT: The objective of this study is to determine the bacteriological parameters using the Petrifilm method for different water sources used in the urban municipality of Kankan. Sampling was carried out in July 2024 at nine sites according to the rate of exploitation by the local population. This study shows that the levels of pathogenic microorganisms such as fecal coliforms, total coliforms and E. coli in ordinary well water and the Milo River are well above the levels recommended by the WHO. The UJNK and CMIS boreholes show no pathology, while the Regional Hospital borehole revealed only the presence of E. coli. Overall, water samples from wells, taps, and boreholes at the various sampling sites are polluted according to WHO standards, with varying levels of pollution. This can be explained by the proximity of some sites to toilets but also by the fact that others are located in markets. The fountains installed in the Senkefara neighborhood showed no presence of CF and CT, but a number of E. coli greater than 100 populations/100mL. All of these results show that consuming this water without proper treatment exposes the population to serious health risks.
