Avaliação da qualidade da água em trecho do rio gurgueia em área de influência de empreendimento solar

Abstract

In recent years, the Brazilian energy matrix has advanced significantly, driven by the use of renewable energy. In this scenario, solar energy has emerged as a promising alternative, especially in the Northeast. Although recognized as a sustainable source, its implementation can generate adverse environmental impacts, requiring further investigation, especially with regard to the preservation of water bodies. This study evaluated the water quality of the Gurguéia River, in the municipality of São Gonçalo do Gurguéia-PI, in an area influenced by a solar project, based on physicochemical and microbiological parameters defined in CONAMA Resolution No. 357/2005. The methodology involved a bibliographic survey and collection of water samples at three strategic points of the river, covering both the dry and rainy seasons. The results indicated total coliform levels well above the permitted limit, evidencing the need for in-depth investigation. The research concluded that, considering the five parameters evaluated, the solar project does not influence the quality of the river. It is recommended that the study be expanded and that continuous monitoring be carried out to ensure the conservation of water resources and environmental security in the region.
