A descriptive research design was used in this study. Three 100ml water samples were collected from School A, another three from School B, and five from School C. The researchers utilized the Multiple Tube Fermentation Technique which has two stages: the Presumptive test and Confirmatory test. These tests were conducted to confirm whether there is any positive presence of total coliform. All of the water samples collected were found to be negative for the presence of Total Coliform. Therefore, the water from the drinking fountains from the selected schools is safe for consumption.
