On top of concerns over the contaminated water is that athletes have been warned that Rio’s aquatic sites remain contaminated
Government and Olympic officials admit efforts to treat sewage and clear garbage from Guanabara Bay and the city’s beaches have been insufficient, prompting warnings from health experts.
The bay will host the sailing and wind-surfing events at next month’s Olympics.
According to New York Times, waters are filled with a a lot of pathogens and viruses with recent tests showing it is more contaminated than first thought.
Not much has changed in seven years with tonnes of raw sewage pumped into the bay every day.
However some have pointed out the events being held in the bay are actually a long way from where the worst pollution levels are.
London-based Brazilian singer-songwriter Isabel Monteiro tweeted the negativity surrounding pollution was misleading.
