What causes my water to get sandy?

I have well water and live at darn near sea level on the east coast. When it rains a lot my water gets very sandy. Once things dry out it clears back up, but you can imagine the problems it causes-no potable water, no showers, etc. What causes this, and any suggestions on how to remedy it?
My tub with sandy tap water after a storm and local flooding.
