Environmental context
The plant discharges into tributaries of the São Francisco River, which flows through the semi-arid Caatinga biome and supports diverse aquatic life, including migratory fish species. The downstream environment includes the São Francisco River basin, which is critical for irrigation, drinking water, and hydroelectric power generation. Proper treatment helps prevent eutrophication and contamination of this vital water resource.
