Resumo: The study analyzed the physical-chemical and microbiological parameters carried out by the Autonomous Water and Sewage Service (AWSS) of the Municipality of Alvorada D’Oeste, Rondônia, Brazil. The parameters analyzed were: pH, turbidity, free residual chlorine, total coliforms (TC), thermotolerant coliforms (TTC) and heterotrophic bacteria. The values of hydrogen potential (pH) were obtained with a digital pH meter. The analyzes were carried out the 2013 to 2019. The turbidity and free residual chlorine values were obtained according to the method of the Practical Manual of Water Analysis of the National Health Foundation (FUNASA). To determine the microbiological parameters, PetrifilmTM plates (3MTM do Brasil Ltda) were used, following the manufacturer's guidelines. The analyzed values were compared with reference values described in Consolidation Ordinance nº. 5, of September 28, 2017, of the Ministry of Health (MS) which sets the standards for potability of water intended for human consumption. The results varied for all parameters evaluated: pH (3.11 to 8.24), turbidez (0.02 to 3,01), TC (0 to 100%), TTC (0 to 100%) and heterotrophic bacteria (85 to 100%). The values obtained for free residual chlorine were the only parameter to follow the reference values. The highest contamination for TC and heterotrophic bacteria were reported in 2019, higher the limits established in Brazilian legislation. Thus, the water was characterized as unfit for consumption and requires severe control for TC and heterotrophic bacteria.

Los parámetros analizados fueron: pH, turbidez, cloro libre de residuos, coliformes totales (CT), coliformes termotolerantes (CTT) y bacterias heterótrofas. Los valores de potencial de hidrógeno (pH) se obtuvieron con un medidor de pH digital. Los análisis se realizaron desde el año 2013 hasta el 2019. Los valores de turbidez y cloro residual libre se obtuvieron según el método del Manual Práctico de Análisis de Aguas de la Fundação Nacional de Saúde (FUNASA). Para la determinación de los parámetros microbiológicos se utilizaron placas PetrifilmTM (3MTM do Brasil Ltda), siguiendo las instrucciones del fabricante. Los valores analizados se compararon con los valores de referencia descritos en la Ordenanza de Consolidación n. 5, del 28 de septiembre de 2017, del Ministerio de Salud (MS) que establece los estándares de potabilidad del agua destinada al consumo humano. Los resultados variaron para todos los parámetros evaluados: pH (3,11 a 8,24), turbidez (0,02 a 3,01), CT (0 a 100%), CTT (0 a 100%) y bacterias heterótrofas (85 a 100%). Los valores obtenidos para el cloro residual libre fueron los únicos que siguieron los valores de referencia. Las mayores contaminaciones por CT y bacterias heterótrofas se reportaron para el año 2019, superiores a las determinadas en la Ordenanza de Consolidación no. 5. Por lo tanto, el agua se caracteriza como no apta para el consumo y requiere un control severo de CT y bacterias heterótrofas.O estudo analisou os parâmetros físico-químicas e microbiológicas realizadas pelo Serviço Autônomo de Água e Esgoto (SAAE) do município de Alvorada D'Oeste, Rondônia, Brasil.
