Katie Ledecky broke her own World Record August 7 when she took first place in the 400m freestyle, claiming her first individual gold of the 2016 Olympics. The following day, Michael Phelps increased his Olympic gold medal count while in Rio to an historic 21 after squashing his rival, South Africa's Chad le Clos.

Despite all the amazing achievements in the water at the games this year, one of the most talked about moments is when the diving pool turned green. As surprising as it may sound, social media was on fire after the episode, with many pitching a number of theories to explain what some believed to be a mysterious event.

The situation turned green yet again with reports of the water polo pool also becoming affected.

UPDATE: We now know what the problem is: Here's a statement from FINA.

The organization also sought to clarify some confusion about this whole situation - the role of Italian manufacturer Myrtha Pools, a frequent supplier for such high-caliber events. It stated that Myrtha equipment was not used in the diving or water polo pools. The manufacturer went a step further and issued its own press release, saying that, while it installed 18 pools for the Games, the diving and water polo pools had been installed for another entity for the 2007 Pan-American Games.

"These pools were not updated for the Olympics and operate with obsolete filtration and circulation, as well as disinfectant systems that necessitate manual chemicals dosage," the company said in its statement. "The systems are simply not able to monitor and control the clarity and quality of water needed for international swimming competition."

Perhaps it's time for organizers to call in a more qualified CPO.
