The objective of this work is to characterize the microbiological quality of bottled natural mineral water sold in Viçosa - MG and understand users' perceptions related to this source of water supply for human consumption. To diagnose the quality of bottled water samples were collected from four brands of natural mineral water bottled in gallon 20 liters for microbiological evaluation. The quality of these waters was verified by bacteriological tests for Escherichia coli, total coliforms, Enterococci, Pseudomonas aeruginosa and values of color and turbidity. The profile of consumers of bottled water, the perception of water quality and factors that motivate the choice of this type of water were studied by means of interviews with application of qualitative method employing the strategy of content analysis. For the presence of total coliforms only brand D showed this bacterium, equivalent to a contamination of 25 % of the samples from this brand. There was no presence of E.coli in any brand analyzed. For enterococci, all the brands had at least once this bacteria, and the brand B showed contamination of 37.5 % of the studied samples. Presence of P.aeruginosa was observed in two marks (A and C) contaminated with 25% of the investigated samples for each brand. Regarding the qualitative study on consumer perception of bottled natural mineral water was observed that the question of why choice for consumption of bottled water is less related to the sense of health protection and more to the spread of a social practice, consolidated and legitimated in everyday life.
