In 1994, I visited Rio and somehow met a computer scientist who was responsible for the sole internet POP in all of Brazil. He even took me into the university lab to see the equipment. It turns out his wife worked as a civil engineer for the city of Rio at the time, and she worked on waste water. He told me it would take her an hour of studying the latest data about weather, currents, and water tests before she would take their kids to the one specific beach that was safest that day. At least back then, all the beaches were polluted, just some were better than others.
