Water pollution in Rio de Janeiro extends farther offshore than previously realized, according to a new report released in advance of the Olympics to be held there next year.

Tests conducted by the Associated Press suggest that areas to be used during Olympic competition are filled with pathogens that can damage human health. Sewage and industrial waste empties into the water surrounding the city. The level of pollution would likely result in the closure of the beaches in the U.S. or Europe, according to the report.

A number of sports require athletes to soak themselves in water off the city’s coast and many athletes have demanded clean water during competition.
