      Expert Answers. Groundwater is any water that is pooled or moving beneath the surface of the earth. In some areas groundwater can be found in continuous flowing formations, rather like an underground river that is continually replenished by rainfall or snow melt. In other areas the groundwater, or aquifer, is more static, like a lake.
