Abstract
The present work aimed the verification of the hygienic-sanitary quality, and the concentration of nitrates in bottled water and from private wells used by the population of Jaboticabal, SP, Brazil. For bottled water, three brand marks, three size bottles (20 L, 1.5 L, 0.2 L) and five batches were analyzed. Waters from wells were analyzed in dry and rainy periods. The varieties analyzed in both cases were: Pseudomonas aeruginosa, sulfide reducers clostridium, total coliforms, Escherichia coli, enterococcus, mesophilic aerobic microorganisms and nitrate. The results indicated there's no uniformity in the quality of waters bottled in 20 L containers for the different batches and for the three brand marks, due possibly to deficiency in their preparation for reuse. From 225 analyzed samples, 37% presented themselves as out of standard of potability (Resolucao 274/05 e 275/05). From the seven wells analyzed there has been verified that three wells has the microbiological quality of its water influenced by pluvial precipitations. Two wells presented high level of nitrate. The results showed that 2.8% of water from wells was out of standard of potability (Portaria 518/04)
