It sought to characterize the quality of surface water in major river basins in the State of Rondônia, considering physical and organoleptic properties, chemical and bacteriological. It has also been made and assessing the potability of water quality index - IQA. With the analyzes were obtained descriptive information, and to test the fit of the data to the normal distribution, it used the method of Shapiro-Wilk. The study concluded that surface water generally analyzed exceeded the bacteriological standards of potability, requiring treatment by chlorination or boiling and filtration prior to human consumption.porAcesso AbertoQualidade da águaÁgua superficialRondônia - EstadoAmazônia brasileiraArtigo de Periódico
