Microbiological analysis of water for human consumption of the population of the Pachapiriana population center, chontalí district, jaén province – 2019

Abstract

The present research work called "Microbiological analysis of water for human consumption of the population of the Pachapiriana Populated Center, District of Chontalí, Province of Jaén - 2019" whose objective was to determine the level of microbiological contamination of the water for human consumption in the Populated Center Pachapiriana, District of Chontalí, Province of Jaén - 2019, of 120 homes, 40 homes and 4 water supply wells were considered for the study. In the investigation we worked with the Most Probable Number Technique in which we obtained results that the samples have to be < 1.8/100 ml; while the results obtained are > 6.8/100 ml high for total coliforms, for fecal coliforms it resulted in > 4/100 ml and for E. Coli; If three samples were obtained (9 – 18 and 31) with the indicated value of DS Nº 031-2010, which is < 1.8/100 ml, the remaining 37 samples have the presence of E. coli because the result is > 2/ 100ml It is concluded that, based on the presumptive, confirmatory and complete tests carried out, it was determined that the water supplied to CP Pachapiriana does not meet the microbiological conditions to be considered fit for human consumption because all the samples have an MPN significant number of fecal, total coliforms and E. coli which indicates that the water is contaminated with fecal matter.
