Casing
-a tubular retaining structure,
				  generally metal, which is installed in a drilled, bored, driven, or augered

				  individuals.
Registered Well
-an inventoried well that has

				  available.
Saline Water
-water with a dissolved solids
				  content of 1,000 milligrams per litre or more.
Screen
-a structural tubular retainer,
				  usually metal, used to support the hole in unconsolidated material with
				  openings in the form of slots, whose openings are selected on the basis of
				  adopted standards and allows sand free water to flow freely into the well in
				  ample quantities and with a minimum loss of head. In agricultural wells and in
				  other wells from which the pumping of sand creates little or no problems
				  slotted pipe is used.
Seepage
-the appearance and disappearance of
				  water into the ground surface-a type of water movement.
Standby Well
-a well that is used in
				  emergencies or occasionally as a replacement well for a supply well.
Surface Plug

				  30 feet in length, in wells or holes deeper than 30 feet, and set at or below
				  the top of the casing in the well.
