Rio’s waters have high viral and bacterial counts not only near shore, but also far offshore where athletes will be swimming and rowing.
A new water contamination study showed that the open water on which some Olympic events will be contested in Rio de Janeiro are more widely contaminated by sewage than previously known, according to results from the tests commissioned by The Associated Press.
Researchers found “that high viral and, in some cases, bacterial counts were found not just along the shorelines where raw sewage runs into water bodies, but far offshore." Athletes who are competing in open water swimming, triathlon, sailing, canoeing and rowing would have a 99 percent chance of being infected with a virus by ingesting as little as three teaspoons of the water.
