Abstract: Maranhão is a Brazilian state that stands out for its great water potential, with three rivers basins at the state level and nine river basins at the federal level, also covering the Maranhenses Islands and West Coast hydrographic systems (NUGEO, 2023). However, this large water network in the state, by itself, is not enough to guarantee the supply of quality water for the diverse needs of the people of Maranhão State. Faced with the diverse and constant negative impacts caused to the environment by anthropic activities, it becomes imperative for public authrorities and society to build, together, management and control structures for the use of natural resources, in particular for those of a water nature. In this scenario, there is the sub-basin of the Água Preta River, one of the main tributaries of the Pindaré River, inserted in the Amazonian portion of the Maranhão State, more specifically in the Zé Doca and Governador Newton Bello municipalities, where there are several rural settlements with subsistence agricultural activities, living under precarious conditions. In this scenario of environment degradated, the content of the Água Preta River it is impacted, mainly in relation to the presence of nitrogen and phosphorus compounds. Thus, the present work seeks to identify the factors responsible for the presence of these compounds in the water of the river in question, in addition to the discussions carried out by Gomes et al. (2023), considering the years 2019 and 2021, as a way of contributing to the sustainability management of water resources in the region.
