In short, surface water is more turbid with a higher amount of particulate matter and requires more treatment to make it potable. It is also usually soft water.
Groundwater is usually clear and contains little or no organic contamination as it has naturally filtered through the ground which also makes it harder water. This usually requires filtration and the addition of chlorine to make it potable.
Surface water collects in a watershed and seeps into ground

The wind at the surface of the ground where the molecules are having friction is moving slower than the wind above the surface.
it will be slower near the surface

The difference between surface run-off and subsurface run -off is that surface run-off is that when it is precipitation the water goes on the ground like a river and lake. The water that goes on the top of the ground is going to the oceans. The subsurface run-off is that when it is preciptation the water
Wind at the surface is slower than the "winds aloft" The biggest effect is within a few inches of the ground.
