Access to safe drinking water is a basic human right but 1/3 of the global population do not have access to safe drinking water. This study aimed to evaluate the potability of drinking water collected from commercial food establishments in Dasmariñas, Cavite using the Most Probable Number (MPN) index, Heterotrophic Plate Count (HPC), and detection of fecal coliforms from water samples. Fifty-five percent (n=11) of the samples were positive in MTT which is indicative of the presence of total coliforms. Forty percent (n=8) of the water samples had unacceptable HPC at >6,500 CFU/mL. Thirty percent (n=6) of the drinking water samples were confirmed positive for fecal coliforms (Escherichia coli) as manifested by dark pink colonies in VRBA. In summary, only 45% (n=9) of the collected drinking water samples were considered as potable.
