If the water looks black in a cavern, it's often due to dark surrounding and botton.
In fact, 
underground water tend to be crystal clear and prety still: no waves nor ripples.
That's acording to 
every photo I ever saw and my one spellunking experience. So, it's rgbt 1 fade_color
and relatively 
long fade_distance, have ior of 4/3, variable fresnel reflection, some tight specular.
