I don't know about where you live, but around here, water is nearly 
clear and colorless...I certainly wouldn't drink or swim in this.

Your shadow is yellow because you scatter lots of blue light, but no red 
or green. Clean water scatters very little, and mainly absorbs red 
light, with green coming next and blue coming last. A simple Google 
search should show some real numbers. Scattering media is mainly useful 
for simulating silt, suspended algae/plankton, etc. You've given no 
clues as to what kind of water you're trying to simulate...you need to 
give more information.
