Qualidade microbiológica do córrego barro preto, Trindade-GO, na estação chuvosa de 2011

Abstract

The quality and control of the water has been becoming as a primordial issue, concerning maintaining life, thus requiring no microorganis on it, which ones can prompt healthy risks to the population who depends on, on this case the Trindade’s people. The Barro Preto brook crosses through all the Trindade’s urban region, subjected to various forms of contamination, including microbiological, because of the large volume of rain swept into his path. With this in mind, this project was developed in order to present and discuss possible microbiological contamination caused by disposal of waste accumulated during the dry season in those sectors that are around the stream through the water during the rainy season. 16 samples were collected along the brook Barro Preto and microbiological analyzes madeby the methods of NMP and plating in depth. Resulting in a high level of contaminatio by the totals coliforms, fecal coliform and total count of heterotrophic mesophyll, thus concluding that the stream is unfit for human consumption or leisure, may cause the risk to their use by people who it benefits.
