Back to blue for synchronized swimming competition pool

Goodbye, green. Hello again, blue. Hope you can stick around awhile.

Synchronized swimmers were greeted by clear blue water in the competition pool Sunday after officials worked through the night to replace murky green water that’s become a big embarrassment for Rio Games organizers.

Replacing the water in time for the early-morning training and competition at 11 a.m. local time was a significant challenge — the pool holds nearly 1 million gallons.

But divers were training as expected Sunday morning.

Organizers have insisted there are no health risks posed by the discolored water seen in the pool during and earlier water polo competition and in a different diving pool. Still, visibility underwater is a major issue in synchronized swimming, where competitors spend lots of time underwater and need to be able to see their teammates.
