Análise de coliformes totais e termotolerantes da água dos bebedouros das embarcações que fazem a rota Parintins Manaus-AM

Abstract

The water has many benefits, however, when it presents contamination can cause several damages to the health of the human being. In this way, the water supplied for consumption must have a good origin and be well treated. Therefore, the objective of this study was to evaluate the water quality of the navigational drinkers, who make the Parintins-Manaus-Parintins / AM route using the Defined Chromogenic-Fluorogenic Substrate method, the Colilert reagent, which is characterized by being a rapid laboratory method for detecting the presence or absence of total and thermotolerant coliforms of water from vessel water fountains. . The water of four navigations was analyzed, and analyzes were carried out at the exit of the fluvial means to the city of Manaus-AM and in the return of the fluvial means to the city of Parintins-AM. The drinking water was collected in four vessels, samples were collected with asepsis and without asepsis from the faucets, both at the exit of the boats to the city of Manaus, and in the return of the same to the municipality of Parintins - AM. Sterile sampling bags containing 10% sodium thiosulphate were used, followed by the standards established in the Practical Handbook of Water Analysis of FUNASA. The samples were incubated in the bacteriological oven at 36 ° C and after 24 hours positive results were observed for total coliforms in the four samples collected at the exit of the vessels to Manaus-AM and the samples of the return of the vessels to Parintins-AM were observed positive results for total coliforms in four samples and for thermotolerant coliforms in two samples. Indicating that the water is unfit for the consumption of the passengers that use these fluvial means.
