RICHMOND, VA (WWBT) - There was no getting around it, water at the Rio Olympic Games that was supposed to look pristine and blue turned a murky green color almost overnight.
Athletes joked about it while they were at the games.
"I have no idea what the green pool is, other than Shrek has been in the pool and had a bit of a swim," joked Great Britain Olympic diver Tom Daley.
On social media, American gold medal winning diver David Boudia was a little more stern, tweeting, "Wait, someone playing a joke? Or are we celebrating St. Paddy's day early here in Rio."
If you've been watching the diving, swimming and water polo events, it's a fair bet you probably caught a glimpse of Dr. James Miller of Family Practice Specialists of Richmond.
He's been a national team physician for USA Swimming, and, in Rio, one of ten doctors working with the FENA sports medicine committee keeping athletes safe.
When asked about if there were any concerns about the swimmers diving into the green water, Miller explained that their role was "to determine whether or not the water was safe for the athletes, and to do that, we had to see what was wrong with the water and what the correction process was."
"At no time was there any risk to the athletes," Miller stressed.
The problem was easy to diagnose. Olympic officials finally admitted that water tanks ran out of some of the chemicals used in the water treatment process.
Despite this small glitch, Dr. Miller says his experience in Rio was amazingly trouble free. When asked about if he was concerned about his personal safety, Miller said he really hasn't, adding that "it's very interesting, in that the Brazilian people have been very accommodating to us."
Dr. Miller will be returning home from Rio in about a week.
