Avaliação da contaminação Bacteriana na água dos bebedouros das escolas municipais da zona urbana de Boca do Acre - AM

Abstract

Knowing that water is a vital substance for the survival of terrestrial life, this paper deals with the relevance of water quality in the municipal schools of Boca do Acre-am. The waters of the drinking fountains of nine schools were analyzed after the drinking fountains were cleaned and the water treated with 2.5% sodium hypochlorite. Subsequently, topics about water and the importance of its treatment were lectured. The method used was the Collipaper kit that identifies microbiological agents through a dehydrated gel for Total Coliforms and Escherichia coli. Pathological agents were detected in all drinking water, making it unfit for human consumption. After disinfection of drinking fountains by cleaning, only one school (EMCC) was negative for E. coli and Total Coliforms. Treatment with 2.5% sodium hypochlorite was not effective as expected, this may be because hypochlorite lost its active chlorine due to shelf life or poor storage. Therefore, all schools had bacteriological contamination. Only the EMPNA and EMPF schools located in the Platô do Piquiá neighborhood showed negative results for E. coli and Total Coliforms.
