The Briton simply believes that Olympic glory makes the risk worthwhile.
"Winning a gold medal will make up for anything " it's really not that relevant," Gosling said on Tuesday, discussing the fetid waters. "There are plenty and plenty of reports out there about athletes who their whole life is about winning medals, and anything that happens on the way is kind of irrelevant."
Tests conducted by The Associated Press this year exposed the pollution levels in Rio's waterways. The most recent results released this month showed more contamination than previously believed, increasing the risk to athletes.
In July, the AP reported disease-causing viruses directly linked to human sewage at levels up to 1.7 million times what would be considered highly alarming in the U.S. or Europe. Experts said athletes were competing in the viral equivalent of raw sewage, and exposure to dangerous health risks almost certain.
Recent tests showed the sailing venue of Guanabara Bay to be as rife with pathogens far offshore as it was nearer land, where raw sewage flows from contaminated rivers and storm drains.
"Obviously pollution is a problem, the objects in the water are an issue, but we as athletes do feel the ISAF (World Sailing) and the IOC are doing everything they can within the constraints of it being in Brazil," Gosling said. "For sailing to be in the center of the Olympics right there, for athletes to be able to stay in the village, to be able to go to the opening and closing ceremony, it's a massive deal.
"And the pictures and the films will be incredible. So, while athletes obviously want it to be fair, safe, and clean, just to be there and be part of the actual Rio Olympics is awesome."
Rio's waterways, like those of many developing nations, are extremely contaminated. By the city's own estimate, only half of the waste water following into the bay is treated.
"I don't think anyone is naive enough to suggest the pipe belt miraculously cures all the problems at Guanabara Bay," said Alastair Fox, head of events at World Sailing. "There are all sorts of issues with heavy rainfall and bringing a lot more debris and whatever bacteria into the bay."
Organizers are capping off open pipes through which raw sewage flows into the bay at Marina da Gloria, the launching point for sailing. This is a stop-gap measure that does little to reduce the level of viruses in the bay.
"The marina isn't going to fix everything," Fox said. "Our biggest headache has always been in the Marina da Gloria and the waterfront along Flamengo beach."
Fox said there are "alternative bioremediation and oxygenation" plans that will be implemented if the pipe belt does not fix the problem.
Brazil's economy was booming when Rio was awarded the games in 2009, but the country is now in its worst recession since the 1930s. Those financial difficulties have seen delays to planned projects, including a 60 million real ($19 million) venture to revitalize the city's Marina da Gloria.
Carlo Croce, president of World Sailing, said he had been told by IOC President Thomas Bach to stop pressing Olympic organizers about their failure to complete projects.
"When you face something like the difference in economics that Brazil has faced in the last two years it is difficult to sort of maintain your promises," he said. "They cannot do it, simply. Thomas asked us to please not press too much because we had been over-pressing the (Rio) organization ... the finance was there in the beginning but it's not there anymore."
