Rio diving pool changes color from blue to green overnight

China won its third consecutive diving gold medal on Tuesday, but the buzz was about the color of the water in the diving pool, which turned from a clear blue to a murky green overnight.

The adjacent swimming pool was not affected. Water quality has been a major issue surrounding the Rio Olympics, but in the ocean and lagoons, not the venue pools.

A statement from Rio 2016 organizers says water tests were conducted and there is no risk to athletes. Organizers say they're investigating what caused the color change.

American diver David Boudia, who won silver while diving into blue water on Monday, tweeted a photo of the pool with the text, "Wait is someone playing a joke or are we celebrating St Patty's Day early here in Rio?"

It looks nasty. Diving pool gets less chlorine?

1. PED users turn the water green

[mahina]

24. What is PED?

25. performance enhancing drugs

Vitamin B Complex and Green Urine
by KATHRYN GILHULY Last Updated: May 17, 2015

If you see a change in your urine color, and you're taking B vitamins, don't panic. Depending on the amounts and combinations of B vitamins you take, you may experience changes in urine color. Your urine could turn orange or green. B vitamin complex may include up to eight B vitamins: B-1, thiamine; B-2, riboflavin; B-3, niacin; B-5, pantothenic acid; B-6, pyridoxine; B-7, biotin; B-12, cobalamin; and folate, the synthetic form of which is called folic acid. If you take B vitamins in large doses, you may also experience other side effects, some serious. Consult your doctor before taking vitamin B supplements or if you experience any side effects while using them. Also seek medical attention if you experience pain while urinating along with a change in urine color.

28. That's a whole lot of green pee.

[Rex]

3. Okay who peed in the pool! Fess up!

[roamer65]

6. I did!

I thought it would turn red white and blue though.

[Rex]

14. What did you drink a 64 oz soda?

That is a lot of pee!

[roamer65]

15. A big gulp.

[olddad56]

20. Well, blue mixed with yellow does make green.

[Rex]

22. Hmmmmm....I think you are on to something!

[0rganism]

4. well that don't look right

'nuff said from me.

[SunSeeker]

5. Eeeeeeeuuwww

[Buckeye_Democrat]

7. Copper pipes?

Copper can turn pool water green.

[FrodosPet]

18. Or Sea Dye Marker?

[Buckeye_Democrat]

21. That too. The coloration seems too uniform to be algae, but copper and dye...

could do it.

I'm not really sure how quickly copper could turn that large pool that color, so dye might be the most likely culprit.

[Warpy]

27. That's what I thought

It's too uniform to be biological, it has to be dye.

My guess is that some vandal thought it would be funny.

[forest444]

8. Ah, so this is where the Temer regime has been laundering the loot.

They must have been in a real hurry.

[center]

"You laundered it where!?!"[/center]

[NWCorona]

9. Talk about an algae bloom

The contrast between the two pools is striking.

[Earth_First]

10. Did it rain overnight?

It's possible if the chemicals were off enough in the diving pool, that rain could have affected it's appearance and left the lap pool relatively untouched and drastically different from the diving pool.

Just a thought...

[SansACause]

11. No way that's algae

Almost impossible to get that green overnight by algal growth.

[TrogL]

12. I've had that happen

Just needs a good chlorine shock.

[groundloop]

13. I read on internet that Olympics had contracted with Trump Towers pool care people

I saw it on the internet so it must be true.




added: I just read that the diving pool is kept at a warmer temperature than the lap pool. That would make for more favorable conditions for algae to grow, and also use up chlorine faster.

[Old Vet]

16. Just a little Muratic acid shock treatment.....

would work. But that green overnite who knows.

[Igel]

17. So now the pools match the signage. Similar shades of green, even. Martha Stewart strikes again?

Now, if they could just paint some of the pavement yellow, it would match the Brazilian flag.

Not so much order and progress, though, but at least color coordinated.

[JustABozoOnThisBus]

19. When is St Patrick's Day ...

... when you're south of the equator?

It's a good reason to dye the pool.

[Eugene]

23. They're saying it's a pH problem caused by running out of chemicals.

Reason offered for green water at Rio Olympic diving, water polo pools

Martin Rogers, USA TODAY Sports 4:41 p.m. EDT August 10, 2016

RIO DE JANEIRO – Olympic diving chiefs claimed on Wednesday to have solved an embarrassing saga at the Games’ diving arena that turned the competition pool a deep shade of green and left competitors joking that they were leaping into “a swamp.”

While Rio’s organizing committee and FINA, the world governing body for swimming and diving, insisted the water posed no danger to athletes, the divers and independent water experts have been very skeptical.

FINA said the reason for the discoloration, which was so severe that pairs divers could not see the partner next to them when they submerged, was because the pool’s water tanks “ran out some of the chemicals” necessary for the water treatment process. A water polo pool adjacent to the diving well also is green.

“As a result the pH level of the water was outside the usual range, causing the discoloration,” FINA said. “The FINA Sport Medicine Committee conducted tests on the water quality and concluded that there was no risk to the health and safety of the athletes, and no reason for the competition to be affected.”

Rio spokesman Mario Andrada insisted the “water will be blue from now on” after water experts spent Wednesday morning carrying out a series of tests.

30. And now: Rio Olympic water polo pool starts turning green

The water polo pool at the Rio Olympics is beginning to turn from blue to green - in a similar way to the adjacent diving pool a few days earlier.
...
The Olympic Games organisers blamed a lack of alkalinity levels and said the build-up of algae, which caused the change in colour, posed no risk to competitors.

On Wednesday, the same change in colour was noticed in the water polo pool, which is situated in the same aquatics centre.

Organizers shut pool to treat green water

By Brenda Goh | RIO DE JANEIRO

Olympic organizers canceled diving training on Friday morning and shut the pool in an attempt to restore the water to its original blue color, three days after its emerald hue stirred concern among competitors.

The pool turned green on Tuesday, becoming the subject of numerous jokes and creating a headache for organizers. An adjacent pool used for water polo and synchronized swimming has also started to change color.

Despite promises to restore the color of the pool at the Maria Lenk Aquatic center by Wednesday evening, organizers were still trying to adjust its chemical levels, a spokesman for Rio 2016 told a news conference.

"We have learnt that chemistry is not an exact science. Some things, as you can see, have gone on longer than expected," Mario Andrada said.

Competitors were performing dry training in the venue on Friday, using an area where divers can practise using trampolines, platforms and harnesses.
