Abstract

The Amazon Basin is the largest watershed in the world, concentrating 1/5 of Earth's fresh water. Despite all the grandiosity, it is difficult to find, in some states bordering by it, the areas completely free of pollution. This is the case of the Guajará Bay and Guama River who receive all of organic and inorganic discharge from the city of Belém capital of Pará. The study aimed to verify the conditions of environmental vulnerability of water bodies through the physicochemical and biochemical front of CONAMA Resolution 357-05 considering that is from this river the water that is withdrawn for treatment and distribution in the city. We used the YSI sonde to measure the parameters and chemometrics for the interpretation of results. The results showed that the rivers have preserved their conditions except for pH which proved to be below the recommended minimum.
