The mystery of the green Olympics diving pool has been solved.
FINA, the international governing body of swimming, diving, water polo, synchronized swimming and open water swimming, released the following statement:
FINA can confirm that the reason for the unusual water colour observed during the Rio 2016 diving competitions is that the water tanks ran out some of the chemicals used in the water treatment process. As a result the pH level of the water was outside the usual range, causing the discolouration. The FINA Sport Medicine Committee conducted tests on the water quality and concluded that there was no risk to the health and safety of the athletes, and no reason for the competition to be affected.
