Quality Bacteriological Of Water Samples In Public Schools Of The City Of Tangara Da Serra, Mato Grosso

Drinking water corresponds to all water available in nature and does not pose risks to living beings who consume it. Although there are several important factors that determine the potability of water, the absence of bacteria of the coliform group is one of the main parameters that must be evaluated. In this way, monitoring water quality within the school environment, where students spend much of their time, becomes necessary to ensure that they have access to quality water. Given this context, this research aimed to evaluate the bacteriological quality of water samples from public schools in the Tangara da Serra, Mato Grosso municipality. There were collected two samples on 14 schools and the method used for the detection of total coliforms and Escherichia coli was the use Kit "Colitag (TM)". The results revealed that there were no positive samples for E. coli, however, 21.4% of the samples had confirmation of presence for total coliforms, not meeting the parameters required by decree no 2914/2011 of the Ministry of Health. It is noteworthy that the contamination by bacteria of the total coliform group is a worrisome factor, since these may indicate the existence of enterobacteria in the water. Among the evaluated schools, a school denominated (E2) showed total coliforms in both samples collected. The results make clear that in some schools, there is need for greater surveillance of water quality and identification of local factors that can are linked to found contamination.
