On Tuesday, the Maria Lenk Aquatics Centre's diving pool turned green. Yesterday, the water polo pool followed suit. Various reasons have been, er, floated, depending on who is doing the blaming, I mean explaining:
• It's a change in alkalinity, says Mario Andrada of the Rio 2016 local organizing committee. "We expect the color to be back to blue soon," he said. "...There is absolutely no risk to the athletes or anybody."
• No, actually heat and still air caused an algae bloom, according to the Olympic organizing committee.
• More likely, says FINA, the International Swimming Federation, is that the water tanks "ran out some of the chemicals used in the water treatment process."

This stunning lake at Harpur Hill in the East Midlands of England is just begging you to dive in, no? Problem is, the quarry pool, known as the Blue Lagoon, has a pH level comparable to bleach and is teeming with garbage and dead animals. The bright blue hue (and the high pH) comes from the quarry stone. Signs warning visitors not to take a dip didn't work, so now the High Peak Borough Council recently dyed the water black. "It's not pretty any more," local business owner Rachel Thomas told the BBC. "They don't think they're on holiday in the Bahamas any more, they know they're in Harpur Hill." Read the rest
