Implementación de un sistema de control de calidad microbiológica del agua de consumo humano

Abstract

The importance of quality in water resources for human supply makes it necessary to review systems for surveillance and control of water quality from the catchment sources and their associated problems to distribution to the consumer. Objective: a microbiological quality control system for water for human consumption was implemented in the Canton Cevallos. Methodology the type of research is quasi- experimental because it tries to investigate if there is a relationship between the variables, in this case the relationship between the quality of water for human consumption and the implementation of a quality control system was investigated. Results From a total of 30 samples collected at the catchment, distribution and consumption sites for the microbiological analysis of the study, it was determined that there is no microbiological contamination by total coliforms by the membrane filtration method Standard methods - 9222 D, unlike the results of the 3M Petrifilm method that did have a minimum growth of 1 to 2 CFU in a 6.7% of the total samples. Conclusions: A better option for microbiological analysis of the vital liquid that supplies the population of Canton Cevallos was proposed, being the Standard methods - 9222 D method with the membrane filtration technique, in which it gave us satisfactory results, since the other method used and with the one that currently has in the Laboratory the Petrifilm plate method does not indicate favorable results, presenting a level of minimum significance, being an alternative method it has a superior performance only when the level of samples is low in this study it shows us a low reliability of the results, which has led to the implementation of a better microbiological quality control system for the water consumed by the population of Canton Cevallos.
