Abstract

The monitoring of water resources should be, due to its essentiality, a priority practice, being a challenge in the preservation of distribution sources. Physicochemical, microbiological and organoleptic characteristics define the standard of potability and consumption. In the study, quality parameters of bottled mineral water were evaluated in samples collected at the Center for Technology and Geosciences of the Federal University of Pernambuco. With the aid of a suction pump, aliquots of 500 mL and 100 mL were collected, and the latter was stored in a sterile bag for microbiological analysis. A multiparameter detector was used for the physicochemical tests; EC Petrifilm® Plate culture medium for E. coli and total coliforms; flame photometry for majority cations; FIAlab system for anions and chloride analyzed by titration analysis. The mean values found for T (ºC), pH, conductivity, STD, salinity, Ca2+, K+, Na+, Cl-, NO2-, NO3- and SO42- were 25.1±0.8ºC; 4.26±0.10; 85.25±1.50 μS; 41.35±0.64 mg/L; 0.04 pg/L; 1.90±0.05 mg/L; 0.7 mg/L; 78.23±4.53 mg/L; 26.2±6.1 mg/L; 0.03±0.03 mg/L; 2.6±0.1 mg/L and 11.4±5.4 mg/L, respectively. Microbiological analyses revealed the absence of coliforms and E. coli. The labeling presented the mandatory information and the parameters evaluated comply with ANVISA's RDCs 274/2005 and 717/2022. No alterations were observed that would compromise the consumption of the water investigated.
