RIO DE JANEIRO — 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 at sites 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 A.P. conducted four rounds of tests starting in March.
