The water quality of the Ubá creek, inside and in the outskirts of the town with this name in the state of Minas Gerais, was investigated. Both physico-chemical and bacteriological analyses were performed in this investigation. Also, physico-chemical analyses of the effluents from furniture industries, the main industrial activity in that town, were also carried out. The Water Quality Index (WQI) - based on chemical and biological parameters - was used to determine the quality of the water of this creek. It has been found that inside this town as well as after leaving it, the water of the Ubá creek is of bad quality, due to pollution resulting from both domestic and industrial sewage.
