#Rio2016 - Rio's water 'will be ready' for sailors when the Olympic Games begin in August, according to China's Xinhua News Agency.
Speaking at an event to mark the lighting of the Olympic torch in Athens on Thursday (21 April), International Olympic Committee president (IOC) Thomas Bach told the media: "We are very confident that the competition area for the athletes will offer safe and fair conditions.
"The city, the state and the organising committee are undertaking many efforts and what we see now is that 60% of the surface is clean," he added. "Without the Games it would be zero."
However, Bach made no reference to concerns over viral contamination of the notoriously polluted Guanabara Bay, nor the risk posed to female sailors by the spread of the Zika virus.
