Resumo:The process of globalization and development of countries, the demand for drinking water is increasing. Drinking water safety is maintained by regularizations and inspections that analyze post-treatment water quality, and are essential to ensure consumer safety, and reduce the risks of contamination. The use of inappropriate water for human consumption can cause damage to health, from simpler to more complex diseases, both water quality and its quantity and supply irregularity are determining factors for the occurrence of diseases. A new modality has been taking place in commercial points in Rio Grande do Norte, which collect, store, distribute and sell natural drinking water for human consumption, through a portable electronic fountain, which works from pulses that disperse water at a from predetermined values, with a system that regulates the values for dispensing water according to the price that the customer indicates in the programming of the equipment itself. In this context, the study aims to evaluate the microbiological quality of water commercially distributed through fountains installed in Mossoró, Rio Grande do Norte. Twenty-one samples were collected, which were observed for analysis of total and thermotolerant coliforms, using the most probable number technique (NMP.mL-1), with a series of three multiple tubes, and characterization of enterobacteria. Of the fountain water samples, 33.4% were contaminated with total coliforms, 4.7% with thermotolerant coliforms, and one sample was positive for Klebsiella pneumoniae. The data indicates a possible contamination of the electronic fountain water by a source of human and/or animal fecal material. Reinforcing the need for oversight. health authorities must implement stricter control measures, provide clear information to the population and provide guidance on compliance practices, noting that failures in the quality control of water intended for human consumption pose a risk to public health.
