ANÁLISE DE PARÂMETROS MICROBIOLÓGICOS DO RIO VERDE NO VALE DO SÃO PATRÍCIO, GOIÁS

Abstract

Having an indispensable role in maintaining life on earth, water is an important resource for various vital activities. It is used for public supply, and can be taken from natural sources, such as rivers. Considering that less than 1% of this resource can be used for human consumption, its treatment must be constantly monitored through analyses of physicochemical and microbiological parameters with standards proposed by the entities and legislations related to the environment. Aiming at the monitoring of the standards required by the legislations, this work had the objective of analyzing, characterizing and evaluating microbiological parameters of the Verde river, in the cities of Ceres and Carmo do Rio Verde, in different points: A) bathing spot, B) stretch of the river that passes near the garbage dump of the city of Ceres and C) water catchment site of the IF Goiano - Ceres Campus. The analyses were performed according to the Most Probable Number (MPN) methods APHA 9:2015 and APHA/AWWA/WEF 9221:2012 for total coliform and thermotolerant coliform counts in water. The presence of E. coli in 100% of the points, along with the quantitative results of total and thermotolerant coliforms, also indicate, according to current laws, that the water is unsuitable for human consumption, and for this purpose proper treatment to control microorganisms is essential. Thus, it is evident the importance of proper water treatment before being used for consumption.
