Industrial waste thrown into waterways is a major problem in Brazil. On that premise, this work evaluated the water quality from Ribeirão Santana downstream the area of São Luís de Montes Belos, Goiás, Brazil throughout the year 2021. Physical-chemical and microbiological evaluation revealed inconsistencies (p<0.05) for turbidity, pH, total solids, conductivity, ammonia, biochemical oxygen demand, chemical oxygen demand, total phosphorus, nitrate, nitrite, total Kjeldahl nitrogen, fecal coliforms and total coliforms. Likewise, genotoxic and mutagenic analysis detected the presence of chromosomal abnormalities and micronuclei (p<0.001). Results raise concerns and highlight the necessity for constant water quality monitoring, as Ribeirão Santana directly participates in the municipality water supply.
