So, Someone Dumped 160 Liters Of Hydrogen Peroxide In 2 Olympic Pools

The mystery behind the Rio Olympics’ unsightly, swamp-green pool water appears to be finally solved. The explanation, however, is nothing short of bizarre. 

During a press conference Saturday, Rio 2016 officials added to a growing list of theories about the greening water. On Aug. 5, someone accidentally dumped 160 liters of hydrogen peroxide ― the stuff you use to clean scrapes and burns ― into two pools at the Maria Lenk Aquatic Center, reported The New York Times. The mishap neutralized the chlorine’s ability to kill organics.
