What's added to big fountains that turns the water green?

Why is the fountain blue? Here in Silicon Valley, two parks have Geneva-style fountains in the center of their lakes -- one in Sunnyvale, another in Cupertino. Instead of white, like in Switzerland, the water's a kind of azure turquoise. Why? A caustic acid to burn anyone foolish enough to take a dip? Chemicals to eradicate algae? Please advise.
