Calidad microbiológica del agua potable de acuerdo a la normativa ecuatoriana nte inen 11.08:2014

Abstract

Gastrointestinal infection resulting from the consumption of contaminated drinking water for domestic use prevails due to inadequate control of intra-residential sanitary activities, there are currently routine controls by the Ministry of Public Health that routinely control the quality of drinking water in its distribution networks and in this way they guarantee that the water reaches its destination (home) free of microorganisms, but it does not guarantee the storage or distribution networks within the homes. The presence of coliforms in drinking water are indicators of faecal contamination that lead to digestive disorders such as diarrhea, cholera, dysentery, among other pathologies manifested by Gram-negative bacteria whose origin is the human and animal digestive tract. The present work has as objective to evaluate the microbiological quality of the water by means of bibliographical revision to establish if it is suitable for human consumption. It is based on a qualitative-quantitative study: qualitative because the presence of fecal and total coliforms is determined by the membrane filtration method and quantitative by the quantification of Colony Forming Units (CFU) and confirmation by the Probable Numerous (NMP) method. , according to the Ecuadorian Technical Regulations Based on the study of 28 samples from different houses, it was possible to identify that microbial contamination factors lie in personal hygiene and poor intra-residential storage processes. It is proposed to avoid storage without proper control of regulatory entities ( MSP) and establish biosafety standards in homes that motivate to avoid possible risks of microbial contamination.
