Abstract

Project paper (B.S.(Environmental & Occupational Health)) – Universiti Putra Malaysia, 2014. Introduction: Water coolers are popular in office buildings and commercial stores and the quality of this source of drinking water has the potential to cause waterborne outbreaks, especially in sensitive and immunocomprornised subjects. The main reason of this research because majority of the students are prefer to take water from the water cooler due to convenience and accessibility factor. Methodology: Two water samples from each college indicates for male and female block were collected and analyzed using USEPA 8367 filtration membrane method to detect the presence of E. coli and total coliform. Results: Total coliform were detected in all sampling point from each college (I4 colleges (100%)) and only one college where E. coli was detected (1 college (0.14%)). Types of water cooler filter did not influence the presence of bacteria because total coliform was detected in all sampling points for each of the Residential UPM Colleges either using Sediment Filter or Stage Filter. Only one college that used Sediment Filter was detected the presence of E. coli. For the consumption frequent and the experienced of getting disease, there were no significant difference because 74 respondents drink less than 3 times will also get the disease and there were 99 respondents were do not develop any disease. Conclusion: No hypothesis can be accepted from this study but it is good approach if every college takes a responsibility to search and eliminate the sources of bacterial contamination in drinking water. Keywords: Water cooler, E. coli, total coliform, USEPA 8367 filtration membrane method
