The comparative study on the bacteriological examination of tap water and sachet water was carried out in Ozoro Community, to ascertain the presence of bacteria in both water samples in Delta State. Twelveâ€™s (12) samples were used, six samples were collected from tap water and they are indicated, A, B, C, D, E and F. while the other six were collected from sachet water indicated as, G, H, I, J, K and L respectively. The pH of the tap water samples ranged from 6.0 to 8.0 while the temperature ranged from 26.50C to 27. 90C while pH of the sachet water ranged from 5.5 to 7.0 and temperature ranged from 26.30C to 27.50C. Total bacterial count for tap water ranged from 1.9x103 to 5.7x103 cfu/ml, total bacteria count for sachet water ranged from 1.2 x103 to 7.5 x 103 cfu/ml. Tap water percentage ranged from 1.14% to 3.51%, while the sachet water ranged from 0.72% to 4.41%. Eight (8) bacterial isolates were identified in tap water Samples; Staphylococcus aureus, Salmonella typhi, E.coli, klebsiella, proteus, vibro cholerae, shigella and Enterbactera cloacae while five (5) were isolates from sachet water, salmonella, Staphylococcus aureus, vibro cholera, E.coli and shigella dysentaria. After the examination of the six samples of tap water compared with six samples of sachet water, it was found that these sources of drinking water in the community are loaded with pathogenic organisms.
