In a suburb of Buenos Aires, the capital of Argentina, a waterway turned bright red on Thursday, causing concern among locals. The Sarandí Canal runs through residential areas and industrial zones before connecting to the Rio de la Plata estuary, which is adjacent to an ecological reserve. Reports from local media indicated that the red color may have resulted from the discharge of textile dye or chemical waste from a neighboring facility. Authorities have collected samples to identify the origin of the pollution.
