well" means a well excavated into a shallow aquifer;
(5) "Spring" means a place where, without

well which is constructed by driving a permanent casing with a screen area into
unconsolidated material. Driven wells do not penetrate consolidated
rock;
(7) "Gravel well" means a
well constructed into unconsolidated material. In the zone immediately
surrounding the well screen more permeability is obtained by hydraulic action
or by removing the finer formation material and replacing it with artificially
graded coarser material;
(8)
"Drilled well" means a well constructed by drilling a hole and inserting a
casing to support the sides of the hole. The portion of the well which is in
consolidated rock may not require support of a casing;
(9) "Annular space" means the space between
two objects, one of which is surrounded by the other. This includes space
between the wall of an excavation and the wall of a pit; between the wall of an
excavation and the casing of a well, or between two casings;
(10) "Casing" means an impervious, durable

intersection of the well casing;
(12) "Pollution" means the adverse effect on

condition which may result in pollution of a ground water supply; it may
include a stream, pond, sewer, privy, septic tank, tile field, cesspool,
sewage, sewage treatment unit, industrial waste, industrial waste disposal
unit, location where animal excrement is allowed to accumulate, or disposal
site for refuse, industrial waste, sewage sludge or industrial waste
sludge;
(15) "Well top seal" means
an arrangement used to establish a watertight junction at the top of the casing
of a well with special regard to the piping or equipment installed
therein;
(16) "Well vent" means a
piped outlet at the upper end of a well to allow maintenance of atmospheric
pressure within the well casing;
(17) "Well pit" means a structure built
wholly or partly underground to house the well top or well appurtenances or
both;
(18) "Yield" means the
quantity of water delivered per unit of time which may flow or be pumped
continuously from the well;
