Assessment of the Bacteriological Quality of the Drinking Water Consumed in a Condominium of Students
Journal Title: Scholars Academic Journal of Biosciences - Year 2014, Vol 2, Issue 9
Abstract
The quality control of drinking water draws attention mainly from the bacteriological standpoint. The purpose of this study was to verify the bacteriological quality of the water distributed in a condominium of students. To determine the presence of fecal bacteria indicators, Pseudomonas aeruginosa and Aeromonas spp, the membrane-filter technique was used. For detection of heterotrophic bacteria, the “Pour Plate” technique was applied. The results showed that 40.7% showed a concentration of heterotrophic bacteria greater than 500 CFU/mL; and were positive in 2.7% and 23% for E. coli and Pseudomonas aeruginosa, respectively. The presence of Aeromona ssp was observed in 16.3% of the samples. Thus, it has been confirmed that the water used in the condominium studied does not comply with the standards issued by the Brazilian legislation before cleaning. It is clear that sanitary measures should be taken concerning the water consumed in the referred condominium.
