Risk Factors Contributing to Microbiological Contamination of Boreholes and Hand Dug Wells Water in the Vina Division, Adamawa, Cameroon

This study examined the sanitary conditions of public boreholes and hand dug wells water in relation to pathogenic bacteria isolated samples. To assess suitability drinking water, inspection surroundings sources was conducted, membrane filtration technic used trap microorganisms sample other standard microbiological technics were applied check heterotrophic plate counts, total coliforms, fecal coliforms some It observed that there no delineated protection zones around many (61.19%) almost all wells; thus, pruned more contamination than boreholes. Heterotrophic counts significantly different between (p E. coli 157H some. Risk assessment factors contributing showed that: pumps manipulation with feet, such as wastewater dumps, within 10m associated Salmonella spp, Staphylococcus aureuse, coliform = 0.01); wells, presence latrine or septic tank soak-away 10 m poor depth lack internal lining, uncapped trees near animal birds feces, significant Salmonela spp., B. cepaceae, S. aureus 1 < 0.05). Generally collection points are marked very this situation may not change unless contaminating risk fixed measures taken.
