The water is green?

The cleaners of my hotel room leave the plug in the bathtub, so when I turn on the shower I generally return to find the bath full of water. That is all well and good, but the water is a green colour.



Some things to note. When you go to a lake, the water has a greenish hue. When you go to a river in the countryside, the water has a greenish hue. When you run the tap, the water is usually clear. At least this country has natural looking water coming out of its taps.
