ResumoThe sanitary quality of water was evaluated in two micro basins, Bacaxá and Capivari belonging to the Lakes Basin São João in the state of Rio de Janeiro, Brazil, for colimetric and parasitological analysis.Analyses were performed seasonally over a year and the levels of Escherichia coli were within the recommended only in the summer of 2012 and fall, and inappropriate with levels above recommended in winter, spring and summer of 2013 in both the micro basins.Through our observations, we compare the average values of the levels of total coliforms and Escherichia coli between both rivers.Initially, the samples indicate a similarity between the distributions of coliforms and Escherichia coli.However, Mann-Whitney-Wilcoxon test samples indicate that the distributions are different.In parasitological analysis it was observed that in Capivari was detected a greater presence of filarial larvae.Anthropogenic influences mainly by the presence of sewage is being able to compromise the health quality of the micro basins studied carrying a significant pollutant load to the Juturnaíba reservoir.The monitoring of the sanitary quality of the watersheds that supply the population may indicate when it is necessary to adopt more effective measures in the treatment of water supply of cities.
