    ABSTRACT: The present work has as objective to evaluate the quality of the water of the Ribeirão dos Porcos river, at Espírito Santo do Pinhal-SP, Brazil, through microbiologycal anlyses for fecal and total coliform, fecal enterococci, pH, oxygen dissolved. Twenty four samples of water of 6 different points were collected, being made 4 collections of each point, in copies. The microbiologycal analyses, was accomplished by the method of the Most Probable Number (NMP) using by multiple tubes technique. Determination of dissolved oxygen and pH values were made. The results of the microbiologycal analyses showed high levels of fecal and total coliforms (1,1x 105 to 2,4x 105/100 ml) from point 1 to 6. In the point 1 (nascent), the fecal total coliforms and fecal enterococci, was inside of the acceptable limits. The results showed largest pollution indexes with fecal coliforms, of the point 2 to 6, mainly in the urban zone, where the river receives domestic and industrial effluents.
