The waters where Olympians will compete in swimming and boating events next summer in South America's first Games are rife with human sewage and present a serious health risk for athletes, as well as for visitors to the iconic beaches of Rio de Janeiro.
An Associated Press investigation found dangerously high levels of viruses and bacteria from sewage in venues where athletes will compete in the 2016 Olympic and Paralympic water sports.
In the first independent comprehensive testing for both viruses and bacteria at the Olympic sites, the AP conducted four rounds of tests starting in March. The results have alarmed international experts and dismayed competitors training in Rio, some of whom have already have fallen ill with fevers, vomiting and diarrhea.
Water pollution has long plagued Brazil's urban areas, where most sewage isn't collected, let alone treated. In Rio, much of the waste runs through open-air ditches to fetid streams and rivers that feed the Olympic water sites and blight the city's picture postcard beaches.
Brazilian authorities pledged that a major overhaul of the city's waterways would be among the Olympics' most significant legacies. But the stench of raw sewage still greets travelers touching down at Rio's international airport. Prime beaches remain deserted because the surf is thick with putrid sludge, and periodic die-offs leave the Olympic lake littered with rotting fish.
