The blue green colour looks like verdigris, oxydized copper. I'm no chemist/metallurgist, but I wonder if there's copper in the water? I've never heard of this, I'd love to know!

Donal (Loneswimmer)

Quick check says it might be copper. It can be added as a sulphate to turn water blue, or it might be leaching in from dissolving copper-heating coils or it might be used as an algicide. I think it's used as an algaecide if they aren't cleaning the pool properly.

Doesn't look like it's dangerous, but the pool should chelate (sequester) it out or it damages everything if they aren't adding it themselves. Oh, it might change your hair colour!

Yikes, thanks Donal. That does explain what happens to the hair of all the toe-headed embassy kids here!
