text: Unconfined aquifers are also known as "water table aquifers" because they usually have a significant vadose zone between the land surface (in the upper, unsaturated part of the aquifer) and the water table; the depth of the water table, and thus the thickness of the unsaturated zone, fluctuates seasonally in response to precipitation patterns, groundwater recharge, and water levels in adjacent streams.
