Samples were taken directly using a sterile bottle, while data analysis using Most Probable Number (MPN) tables 5-1-1 and the presence of E. coli bacteria colonies from drinking water samples. Results: 9 of 15 water samples were contaminated by coliform bacteria with the highest MPN index of 240/100 ml that was found in 2 samples. From 9 samples containing coliform bacteria, all of them were found to contain E. coli bacteria. Conclusion: Most of the samples were contaminated by coliform and E. coli bacteria.
