The Current work to assess the capacity of water potability samples for that, we used seven different brands of mineral water, bought locally, and also collected seven samples of public drinking fountains located in different places on campus headquarters of the State University of Maringá. The parameters analyzed were presence of fecal and total coliform, turbidity, color and compounds with UV-absorption at 254 nm. On the analysis of coliforms, two brands of mineral water and four samples of drinkers showed presence of total coliform, but no analysis indicated the presence of fecal coliforms. In the turbidity parameter, all samples were within the limits allowed by law, for both cases. No apparent color attribute, two samples of mineral water and a sample of drinking were outside the range required by law. Finally, the determination of UV showed the values of light absorption of each sample at a wavelength of 254nm, however, does not yet exist in Brazil a regulation on this parameter. With such analysis, it was possible to compare the results with current legislation. After these findings, it appears that more stringent hygienic practices should be adopted throughout the processing of mineral water as drinking in public. It is also necessary for greater oversight over the other parameters for determining the quality of water.
