This study was carried out to investigate the physicochemical and bacteriological quality of well water samples in Ido community. Thirty water samples were collected from five different wells ( six samples from each well) and subjected to standard microbiological and physicochemical analysis. All physicochemical properties showed difference (p 0.05) across the wells. However, Total Heterotrophic Bacteria ranged from 2.15±0.91×104 to 5.3±0.86×104cfu/ml; total coliform, 3.00±0.77×104 to 6.18±0.73×104 cfu/ml; Total feacal coliform, 2.61±0.71×104 to 4.39±0.76×104 cfu/ml; Total vibrio count, 2.68±0.81× 103 to 4.4±0.86×103 cfu/ml; Total salmonella shigella count. 2.02±0.84×103 to 4.8±0.95×103 cfu/ml. Total coliform bacteria ranged from 220 to > 1600 coliform MPN index /100ml-1, while thermo tolerant coliform bacteria ranged from 220 to 1600 coliform MPN index /100ml-1. A total of forty bacterial isolates belonging to ten genera were identified. They include species of Bacillus 22 (26.4%), Staphylococcus 14(16.8%), Vibrio 13(15.7%), Serratia 6(7.3%), Enterobacter 6(7.3%), Chromobacterium 4(4.8%), Salmonella 4 (4.9%), Shigella 4(4.8%) and E. coli 4(4.8%). This result highlights the fact that well water in Ido community are not safe microbiologically for drinking without additional treatment such as boiling or disinfection and this could lead to outbreak of water borne diseases. Good and proper environmental and personal hygiene is advocate especially by the users of those wells to prevent their contamination with bacterial pathogens.
