RIO DE JANEIRO — We know why the pools of Rio have been turning a Nickelodeon-slime shade of green in the last few days. Suffice it to say, no one here is shocked.
As the head of the International Swimming Federation (FINA) told the Los Angeles Times, “FINA can confirm that the reason for the unusual water color observed during the Rio diving competitions is that the water tanks ran out of 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 discoloration.
