Abstract: BAWIT, JOY G. April 2008 "Microbial Evaluation of Drinking Water from the Refilling Stations Near the CvSU Campuses". Undergraduate thesis, Bachelor of Science in Biology, Department of Biological Sciences, College of Arts and Sciences, Cavite State University, Indang Cavite. Adviser: Dr Yolanda A Ilagan A study was done to determine the heterotrophic plate count of drinking waters from refilling stations near the CvSU campuses and to identify the microorganisms present in drinking waters from the refilling stations. Fourteen samples of commercial bottled water per sampling period were collected from the refilling stations near the CvSU campuses. Based on the presumptive, confirmatory and completed test, the highest occurrence of E. coli were detected during 3rd sampling period from the 2" refilling station of Rosario campus, with the MPN value of 40 per 100m1 of samples, while the lowest MPN value was observed in the 2" sampling period which was within the range of the accepted MPN value of <2 to 2.2. Bottled water sample obtained near Imus campus exhibited the highest count average of 17.5 x 102 cfu/ml. While bottled water sample obtained near Trece Martires City campus had the lowest average of 10.0 x 102 cfu/ml. A total of 106 bacteria were isolated and identified. The bacteria are include in the genera of Enterobacter, E. coli, Salmonella, Serratia, Proteus, Pseudomonas and Staphylococcus. Among the bacterial isolates, Enterobacter was the most widely distributed genus being present in all refilling station near the CvSU campuses. The heterotrophic plate count of some water sample obtained from different refilling stations near CvSU campuses recorded a range beyond the accepted value for HPC and MPN. This suggests that the quality of water being sold by some refilling stations are below standard, hence monitoring of the proper authorities together with the local health units is a must.
