The general quote “water is an elixir of life” is successful when the drinking water is available in germ free condition. The cleanliness and hygienic state of drinking water play an important role in the health state of the population. On comparing with other vehicle reservoir, water is considered as a potent and fastest source of spreading various infectious diseases. The study was carried out to investigate the packaged drinking water available in Tiruchiarapalli city. In the present study, eighty five samples grouped under five brands where one was national and four were local. All the samples were subjected to viable count and presence or absence method. The samples showed positive to the test were further subjected to multiple tube method for determination of total coliform analysis. As a result twenty eight out of 85 samples had viable count higher than specified by Bureau of Indian Standard. Twenty three samples were found to be positive in presence - absence test. Further all the 23 samples subjected for total coliform analysis thereby 20 samples confirmed the presence of Escherichia coli. It is highly unexpected to have coliforms in packaged drinking water. It clearly indicates the laxity in exercising stringent quality control measures by the manufacturers.
