Rio officials blame green pool on contractor, plan total water swap
By Greg Wyshynski | YahooSports | August 13, 2016, 2:58PMRIO DE JANEIRO – What caused the pools for Rio Olympic water polo, diving and synchronized swimmer to turn a disgusting shade of green?
Human error.
That was the definitive answer from Gustavo Nascimento, director of venue management for the Games, who said a mistake by a contractor hired to maintain the water caused the discoloration and the several days spent attempting to remedy it – days that will end with the entire water polo pool being drained and refilled ahead of synchronized swimming.
“Before the games on Tuesday, the water turned green. We investigated the causes that put us in this situation, and there are two main sources that have potentially made this water turn green. Maybe it’s a combination of both. We can never be certain because the chemicals that made the green are already gone,” said Nascimento.
Problem No. 1: On Friday, the day of opening ceremonies, 80 liters of hydrogen peroxide were added to the water by a contractor. While hydrogen peroxide can be used as a way to kill organics in the water, it’s not something that is used in addition to chlorine.
So not only did the contractor not add the right amount of hydrogen peroxide for a large pool, but by adding it to the pool, it effectively “neutralizes the chloride’s ability to kill organics,” said the organizers, “it was asleep.”
This was not something “that should have been done,” according to Nascimento, but ultimately “our contractor’s failure is our failure.”
