Physicochemical and Bacteriological Characterization of Surface and Stored Groundwaters in Natitingou, Benin Republic

Surface and groundwater collected in the municipality of Natitingou constitute a potential infectious risk for human health environment due to pathogenic bacteria Chlorella vulgaris they contain after conservation tanks. In this study, surface samples were analyzed according. The results physicochemical bacteriological characterization these water revealed average values pH (4.35 6.98), turbidity (0.65 169.97 NTU), nitrites (0.15 5.40 mg/L), nitrates (0.55 114.34 ammonium (0.05 0.60 mg/L) significant faecal contamination by total coliforms, coliforms enterococci. analysis also reveal presence both conserved. shows positive correlation with nitrates, negative phosphates, enterococci proliferation groundwater. consumption without any treatment could expose populations waterborne diseases.
