The Associated Press reveals the results of its investigation into the safety of the water at the 2016 Olympic venues in Rio de Janeiro, Brazil. The findings come a few days ahead of this weekend’s paratriathlon and elite triathlon Olympic test events. Copacabana Beach, where the swim portion of the triathlons will take place, was one of the least-polluted areas tested but still contained a concentration of viruses “roughly equivalent to that seen in raw sewage.”
Athletes in next year’s Summer Olympics here will be swimming and boating in waters so contaminated with human feces that they risk becoming violently ill and unable to compete in the games, an Associated Press investigation has found.
An AP analysis of water quality revealed dangerously high levels of viruses and bacteria from human sewage in Olympic and Paralympic venues—results that alarmed international experts and dismayed competitors training in Rio, some of whom have already fallen ill with fevers, vomiting and diarrhea.
It is the first independent comprehensive testing for both viruses and bacteria at the Olympic sites.
Brazilian officials have assured that the water will be safe for the Olympic athletes and the medical director of the International Olympic Committee said all was on track for providing safe competing venues. But neither the government nor the IOC tests for viruses, relying on bacteria testing only.
Extreme water pollution is common in Brazil, where the majority of sewage is not treated. Raw waste runs through open-air ditches to streams and rivers that feed the Olympic water sites.
As a result, Olympic athletes are almost certain to come into contact with disease-causing viruses that in some tests measured up to 1.7 million times the level of what would be considered hazardous on a Southern California beach.
Despite decades of official pledges to clean up the mess, the stench of raw sewage still greets travelers touching down at Rio’s international airport. Prime beaches are deserted because the surf is thick with putrid sludge, and periodic die-offs leave the Olympic lake, Rodrigo de Freitas, littered with rotting fish.
“What you have there is basically raw sewage,” said John Griffith, a marine biologist at the Southern California Coastal Water Research Project. Griffith examined the protocols, methodology and results of the AP tests.
“It’s all the water from the toilets and the showers and whatever people put down their sinks, all mixed up, and it’s going out into the beach waters. Those kinds of things would be shut down immediately if found here,” he said, referring to the U.S.
Vera Oliveira, head of water monitoring for Rio’s municipal environmental secretariat, said officials are not testing viral levels at the Olympic lake, the water quality of which is the city’s responsibility.
The other Olympic water venues are under the control of the Rio state environmental agency.
Leonardo Daemon, coordinator of water quality monitoring for the state’s environmental agency, said officials are strictly following Brazilian regulations on water quality, which are all based on bacteria levels, as are those of almost all nations.
“What would be the standard that should be followed for the quantity of virus? Because the presence or absence of virus in the water … needs to have a standard, a limit,” he said. “You don’t have a standard for the quantity of virus in relation to human health when it comes to contact with water.”
Olympic hopefuls will be diving into Copacabana’s surf this Sunday during a triathlon Olympic qualifier event, while rowers take to the lake’s water beginning Wednesday for the 2015 World Rowing Junior Championships. Test events for sailing and marathon swimming take place later in August.
More than 10,000 athletes from 205 nations are expected to compete in next year’s Olympics. Nearly 1,400 of them will be sailing in the waters near Marina da Gloria in Guanabara Bay, swimming off Copacabana beach, and canoeing and rowing on the brackish waters of the Rodrigo de Freitas Lake.
The AP commissioned four rounds of testing in each of those three Olympic water venues, and also in the surf off Ipanema Beach, which is popular with tourists but where no events will be held. Thirty-seven samples were checked for three types of human adenovirus, as well as rotavirus, enterovirus and fecal coliforms.
The AP viral testing, which will continue in the coming year, found not one water venue safe for swimming or boating, according to global water experts.
Instead, the test results found high counts of active and infectious human adenoviruses, which multiply in the intestinal and respiratory tracts of people. These are viruses that are known to cause respiratory and digestive illnesses, including explosive diarrhea and vomiting, but can also lead to more serious heart, brain and other diseases.
The concentrations of the viruses in all tests were roughly equivalent to that seen in raw sewage—even at one of the least-polluted areas tested, the Copacabana Beach, where marathon and triathlon swimming will take place and where many of the expected 350,000 foreign tourists may take a dip.
