It is due to the absorption of sunlight. Shorter wavelengths (red/orange) get absorbed by the water at a very shallow depth. The longer wavelengths (blue/purple) get through the water farther. This is why Scuba divers lose the red/orange end of the color spectrum as they descend...those colors don't make the depth, just the blue/purple end of the spectrum.
In a white pool, the colors of light that get through to the bottom are reflected back to the surface, traveling through more water and losing more of the reds. What you see is the blue color reflecting back. The deeper the water, the deeper the color you see.
You will also notice that this is a daytime phenomenon. The pool light does not give you the same blue-color effect.
