Disorderly population growth and urban expansion have impacted the environmental quality of water ecosystems. The Igarapé do Coroado in Manaus receives rainwater and untreated sewage, affecting its quality. The study analyzed physicochemical and microbiological parameters to assess environmental degradation. Samples were collected at five strategic points in different periods of the day. Results indicated contamination above the standards established by CONAMA 357/2005, compromising the biota and public health. The study highlights the need for public policies for the recovery and preservation of urban water resources.
