The purpose of this test was to evaluate the physicochemical (ammoniacal nitrate, nitrogen nitrate, nitrogen nitrite, pH,orthophosphate and turbidity) and microbiological parameters (Escherichia coli and total coliforms) of mineral water samplesbottled trademarks and compare the results obtained with Brasilian Ministery of Healty Ordinance 2.914/11. For this purpose,it was used trademarks mineral water bottled sold in pet 300 and 500 ml bottles. For microbiological analysis it was usedColipaper (Alfakit®), and all of them the analysis of physicochemical parameters was used Ecokit II (Alfakit®). From the fivemineral water bottled samples, all were within the physicochemical parameters determined by Ordinance 2.914/11. In themicrobiological findings, only one sample presented Escherichia coli. Therefore, all the analyzed brands meet the requiredphysicochemical parameters of water quality for human consumption, except brand A, which did not meet the microbiologicalparameters. The results demonstrates the need for confirmatory tests performed by laboratories qualified to attest the resultobtained, as well as the need to implement more effective monitoring by the responsible agency for monitoring the waterquality for human consumption.
