Análise bacteriológica da água de consumo em escolas públicas municipais de uma cidade do interior do Amazonas

Abstract

Introduction: Ensuring the safety and potability of water depends on the proper functioning of several stages of the supply process, from treatment to distribution. Objective: To evaluate the microbiological quality of water for human consumption in municipal public schools in Coari, Amazonas, Brazil. Method: The collection of information regarding the schools was carried out by means of a letter sent to the Municipal Education Department. Water samples from all schools they were analyzed. The collection they were carried out in accordance with the 23rd edition of the Standard Methods for the Examination of Water and Wastewater, for which collections they were carried out at the water source (tubular or artesian wells), water reservoirs and direct points of consumption (drinking fountains). After collection, the samples they were transported under refrigeration to the Microbiology laboratory of the Institute of Health and Biotechnology, Coari campus for microbiological analysis. All analyzes they were performed in triplicate using the membrane filtration method and the results they were presented by means of analysis of the presence or absence of E. coli, totals. Expected results: In 2023, the municipality has 11 active schools, serving 6693 students. The total number of employees is 1027. As for the supply of water for human consumption, only 10% of the schools are served by the municipal water company, the remainder is supplied by water from an underground source (tubular well). Conclusion: The research will diagnose the bacteriological profile of water for human consumption in municipal schools, allowing to understand the quality of the water consumed and thus mitigate possible problems.
