The plant's location inland, away from coastal zones, means its discharge affects freshwater systems. The surrounding area drains into the Parnaíba River basin, which is ecologically significant for the semi-arid Caatinga biome and supports diverse aquatic life.
Environmental context
The plant discharges into local waterways that are part of the Parnaíba River basin, one of the major river systems in northeastern Brazil. The Parnaíba River flows northward to the Atlantic Ocean, forming the Parnaíba Delta, a region of ecological importance. The semi-arid climate of Piauí makes water quality management critical for sustaining local biodiversity and supporting downstream communities.
