Evaluation of the presence and quantification of total coliforms and Escherichia coli in samples of water intended for human consumption from artesian wells
Keywords:
Water quality, Escherichia coli, Artesian wells.Abstract
Water is essential for life and its contamination by pathogenic microorganisms offers great risk to human health and may cause illnesses ranging from mild gastroenteritis to life threatening diseases. Thus, water for human consumption should be free of pathogenic microorganisms and must not contain indicators of faecal contamination such as Escherichia coli presence. Given the importance of drinking water quality for health, this study aimed to verify the bacteriological quality of water used for human consumption from 200 artesian wells located in the city of Cambé - Paraná, from 2013 to 2017. The methodology used for the research of total coliforms and E. coli was the Colilert® chromogenic substrate method. Among the 200 analysed water samples, 113 (56.5%) were contaminated with total coliforms and 35 (17,5%) with E. coli. The analyses carried out during the five-year period allowed finding 14 (7%) treated water samples that showed contamination by bacteria of the coliform group. Based on the results obtained in this study, it is expected that both the population and the public agencies will be aware of the importance of water quality control for the prevention of diseases transmitted by this means.Downloads
