well" means a well regulated under this part for which use has been
discontinued for more than one year and the owner does not desire to maintain
this well for future use; or its use has been permanently discontinued or is in
such a state of disrepair that it cannot be used for its intended
purpose.
(b) "Annular space" means
the space between the well casing and the wall of the drilled hole or between
two well casings.
(c) "Artificial
recharge well" means well constructed to introduce water into the ground as a
means of replenishing groundwater basins.
(d) "Commercial, municipal and industrial
waste well" means well constructed to dispose of unusable waste or contaminated
water resulting from a commercial activity, municipal collection, storage or
treatment facility or an industrial activity.
(e) "Conductor casing" means a tubular
retaining structure installed in the upper portion of a well between the wall
of the drilled hole and the inner well casing.
(f) "Confining formation" means an
impermeable bed or a bed of distinctly lower permeability than the adjacent
material in which groundwater may be moving.
(g) "Destroyed well" means a well that has
been properly filled so that it cannot produce water nor act as a vertical
conduit for the movement of groundwater.
(h) "Geothermal well" means a well
constructed to extract or return water to the ground after it has been used for
heating or cooling purposes.
(i)
"Key seating" means a stuck drill pipe or casing caused by an abrupt change in
direction or dogleg in the drilled hole.
(j) "Miscellaneous discharge well" means a

scope.
(k) "Observation and monitor
well" means a well constructed for the purpose of observing or monitoring
groundwater conditions.
(l)
"Production casing" means a tubular retaining structure installed in the upper
portion of a well between the wall of the drilled hole and the inner well

the access to the well casing that allows the water level in the well to be
periodically determined. All sounding tubes should have a screw cap.
(n) "Special process discharge well" means a
well constructed for the use of a subsurface discharge for recovering a product
or fluid at the surface. Special process discharges are defined in detail in
Chapter 9, Wyoming Water Quality Rules and Regulations.
(o) "Test well" means a well constructed for
obtaining information needed to design a well prior to its construction. Test
wells are cased and could be converted to observation or monitoring
wells.
(p) "Watertight" means
impermeable to water except when under such pressure that structural
discontinuity is produced.
