NITEROI, Brazil (AP) — With thousands of liters of raw human sewage pouring into the ocean every second from Rio de Janeiro, August's Olympic Games have thrust into the global spotlight the city's spectacular failure to clean up its waterways and world famous beaches. But just across the Guanabara Bay from Rio, the sister city of Niteroi is showing that a real cleanup is possible.
In Niteroi, 95 percent of sewage is treated and authorities say they are on track for 100 percent within a year, even though Rio's failure to do its part means that sludge still flows in from across the bay.
