This study aimed to evaluate the water quality of the lower portion of Una River Basin, Pernambuco, by means of analysis of physical, chemical and microbiological parameters. The monitoring was conducted among October 2013 and March 2014. Sampling locations were in the cities of Catende, Palmares and Água Preta, selecting three collection points in each district. Parameters analyzed: temperature, electric conductivity, dissolved oxygen, biochemical oxygen demand, turbidity, potassium, pH, total phosphorus, thermotolerant coliforms, and Escherichia Coli. The results showed the water quality in the Basin Una River is outside of CONAMA standars Resolution 357/2005 for fresh water Class II parameters: dissolved oxygen, pH, phosphorus, thermotolerant coliforms and Escherichia Coli. Potassium concentration shows the discharge of effluents from the processing of sugar cane in the hydrous body did not affect the quality of the water. The main contamination source of water was the release of domestic sewage.
