The objective of this study was to evaluate the water quality of Rio Bonzinho in the city of Ji-Paraná, RO. We established 02 sampling points in the river. We analyzed the following variables of quality: fecal coliform, biochemical oxygen demand,phosphates, nitrates, dissolved oxygen, pH, total solids, temperature and turbidity. Results were analyzed against quality standards for Class 2 and grouped to calculate the Water Quality Index (WQI). Most variables met the quality requirements for Class 2 and WQI was interpreted as "Regular".
