Abstract


The Tocantins River has abundant water resources and favorable conditions for recreational activities, with emphasis on the beautiful natural beaches formed along its length. However, it is worth noting that the main contact entertainment and leisure activities require specific health and safety standards for bathing purposes. This study evaluated the water quality of Praia Beira Rio, in Porto Nacional-Tocantins, in only one point. For this purpose, microbiological analysis was performed using indicators of total coliforms and Escherichia coli (E. coli) following the method described by APHA (2005). The monitoring results were compared with the parameters for bathing purposes defined in CONAMA Resolution 274/00. To detect and identify total coliforms and Escherichia coli, the Colilert technique was used. The Escherichia coli content was low, allowing bathing waters to be classified as their own, according to CONAMA Resolution No. 274/00, and subdivided into the "excellent" category. Therefore, according to the bacterial indicators of the Escherichia coli group, during the analysis period, the waters of Praia Beira Rio were within the standards for primary contact recreation.
