Rio's Olympic Swimming Pools Are Turning Grody Colors

Metaphor alert! Inspectors were dispatched to the Maria Lenk Aquatic Center at the Rio 2016 Olympics on Wednesday to determine why the water in the diving pool, pristine and azure at the start of the week, had turned a murky shade of swamp. Authorities had nevertheless assured athletes competing in the diving pool—as well as in the water-polo pool, which was also turning green—that the water posed no risk.

The source of the problem? Brazil was unprepared to host the Olympic Games.
