Abstract: Background and purpose: The safe drinking water supply is necessary for providing of students health in the university and other educational centers. In this study, the quality of water drinking of water coolers in the different locations of Babol university of medical sciences as physical, chemical and bacteriological parameters were investigated.
Materials and Methods: In this study, turbidity, pH, chlorine residual, total and fecal coliforms and heterotrophic bacteria in the water samples were investigated. All parameters were determined according to standard methods for the examination of water and wastewater. Of the total water coolers (46 units), 19 units were randomly selected. Data obtained were analyzed by SPSS version 19
Results: Turbidity range of the samples varied from 0 to 0.72 NTU. Residual chlorine and pH ranges in the water entering of water coolers were 0.1-0.8 mg/l and 7.44-7.96, while, water outlet of the water coolers were 0-0.4 mg/l and 7.01-8.05, respectively. None of the studied samples contained fecal coliforms, and the non-fecal coliforms of the water samples were 5.3%, while that of heterotrophic bacteria was 10.6%.
Conclusion: Results of this research showed that no bacteria of the non-fecal coliforms in entering water to the water coolers, which suggested the water was safe. However, it was proved that non-fecal coliforms found in water outlet of water coolers, and heterotrophic bacteria existed in before and after of water coolers.
