Análise de coliformes totais e fecais (E. coli) da água do Rio Licungo consumida pela população do distrito de Mocuba, província da Zambézia

Abstract

The present work aimed to analyze the total and fecal coliforms of the water of the Licungo River in the district of Mocuba. Six water samples were collected at six different points such as on the banks, in the center of the river and at its confluence. Water is important for our survival and indispensable for food production and other economic activities. The necessary characteristic for water distributed for human consumption is potability, that is, it must be clean and free from any contamination of microbiological, chemical, physical or radioactive origin, and must not, under any circumstances, pose risks to human health. The analysis of total and fecal coliforms was performed according to the methodological procedures described by the Practical Manual of Water Analysis. Through the analyses carried out it was possible to evaluate whether there was the presence or absence of bacteria of the coliform group; of the six points evaluated, all of which were collected, the presence of Fecal coliforms (440 C) and total coliforms (370 C) was detected, being unfit for consumption. Thus, care is needed with the water of the Licungo River to provide a sanitary quality water for the population.
