Groundwater, 3rd Edition (M21)
This manual provides operators, engineers, and other professionals with a basic understanding of groundwater that will help them make decisions on water-well design and operation.
The manual covers geology, groundwater movement, groundwater quality, regulatory issues, water-well types and construction, pumps, water treatment, water-well problems, and groundwater recharge and storage.

Page 7 - ... underlain by a zone in which all interconnected openings are full of water. This zone is referred to as the saturated zone. Water in the saturated zone is the only underground water that is available to supply wells and springs and is the only water to which the name ground water is correctly applied.
Page 10 - Where water completely fills an aquifer that is overlain by a confining bed, the water in the aquifer is said to be confined. Such aquifers are referred to as confined aquifers or as artesian aquifers. Wells open to unconfined aquifers are referred to as water-table wells. The water level in these wells indicates the position of the water table in the surrounding aquifer.
