You’ve probably heard about how Rio’s sea water is so polluted that only three teaspoons is enough to make an athlete seriously ill. Well, it’s spreading to the pools too. Athletes and tourists have been flocking to social media to ask why this pool seems to have turned green overnight…

And apparently it’s not just this pool…

For reference, here’s a picture of the pool a few days ago.
And here’s the underwater camera from yesterday and again from today.

The reason for the swamp-like color? No one seems to know. No one that should know why, anyway. BBC commentator Bob Ballard asked an organizer and got a less than reassuring “I don’t know.”
Regardless of the fact, the women’s 10m synchronized diving finals still took place in the pool. With viewers and athletes taking to Twitter to joke about the situation.

And everyone who thinks they know their science has been offering explanations. Aimee Lewis of the BBC explains:
“An American photographer in the press room suggests that perhaps organisers did not “shock” the water overnight.”
“‘You know, it’s like back home, if you don’t shock the pool water it turns green. It doesn’t look nice, but it isn’t dangerous,’ he says.”
“If chlorine levels drop, even for one day, it can turn green because of an algae outbreak. Having never owned a pool let alone needed to clean one, I just nod sagely.”
While this Twitter user blames someone forgetting to put the chlorine in:
Whatever the reason, it doesn’t look very inviting.
