Suspicions have been drawn to the water in the diving pool of the women's 10-meter platform synchro match on August 9 at the Rio Olympic Games, which was not the usual blue but dark green.
The odd scene was captured in the live broadcast of the event, and many athletes also posted photos of the swimming pool, on social media to question the bizarre phenomenon.
Some say the regulators of the diving pool turned the water to green on purpose to echo the green color of Brazil's national flag. But few people believe that version, with many more tending to think the color is due to the failure by the pool maintenance technicians to add chlorine to the water.
One more theory says it was Rio's warm weather and abundance of sunshine that led to mass reproduction of algae in the water.
Some spectators and journalists also expressed concerns over the green water, fearing it may affect athletes' performances. The divers in the competition including the gold medalists Chen Ruolin, and Liu Huixia from China, and the bronze medalists Meaghan Benfeito, and Roseline Filion from Canada said the green water didn't seem to affect them much.
Despite this, organizers of the Rio Olympics have promised to investigate the case so that the quality of the games can be guaranteed.
