Do Saco River (Rio de Janeiro)

The Do Saco River, located in the state of Rio de Janeiro, Brazil, is a minor river emptying into Guanabara Bay. It is notable primarily for its small size and its location within a densely populated and industrialized area. The river has historically suffered from significant pollution due to untreated sewage and industrial discharge from surrounding communities and businesses. Efforts to improve water quality in Guanabara Bay, including projects focused on reducing pollution from rivers like the Do Saco, have been implemented with varying degrees of success. Information regarding its length, watershed size, and precise ecological details is limited in publicly available sources, highlighting the river's relatively minor significance compared to other waterways in the region.
