Why Did Rio Olympic Pool Turn Green?

The diving pool at Maria Lenk Aquatics Centre (the pool used for 2016 Rio Summer Olympics) turned not just green, but deep like green.

Isn’t it a threat for swimmers to go swimming in this kind of pool?

To be clear, swimming pools should be in a shade of sapphire or blue, not this green that nearly it would look like a pond.

Obviously, there were many complaints sent to the Olympic organizers and FINA –swimming’s international governing body, and they offered a lot of explanation about the happenings.

#1. Alkalinity Change

“We expect the color to be back to blue soon,” Mario Andrada, the communication director for the Rio 2016 local organizing committee said, adding there is “absolutely no risk to the athletes or anybody.”

Due to alkalinity, minerals can be brought up due to low or high pH. That’s the reason why water could turn cloudy or sometimes show up as blue green. On the other hand, if the chlorine is ineffective, the main cause is too-high pH in which it allows the production of algae.

#2. Bloom of Algae

Too much production of algae is said to be an effect of heat and lack of wind.

#3. Lack of organization

The Rio Olympic organizers said that a lot of the athletes complained about irritated eyes when they pumped too much chlorine onto the pool. Thus, they wanted to fix this problem, but it seemed like it created another problem.

#4. Athletes urinate in the pool

You shouldn’t urinate in the pool especially when it’s used for competition, especially at the Olympics Games. Large mass of urine may have lured the bacteria and algae.

#5. Shrek’s out there farting in the pool

Isn’t it awful!? People’s commenting that it would be nicer if Shrek would appear in the pool, and loan his swamp to the Rio Olympics.
