				  "Water supply well" means an artificial excavation, constructed by any method,
				  for the purpose of getting water for drinking or other domestic use;
(2) "Well contractor" means any person, firm
				  or corporation drilling or constructing a water supply well;
(3) "Aquifer" means a water-bearing earth
				  material which can transmit water in significant quantity. It can be either
				  consolidated rock (ledge rock) or unconsolidated material (sand, gravel, soil
				  with boulders, etc.);
(4) "Dug
				  well" means a well excavated into a shallow aquifer;
(5) "Spring" means a place where, without
				  planned intervention of man, water flows from consolidated rock or
				  unconsolidated material on land or into a body of surface water such as a lake,
				  stream, or river. A spring shall have the same protection requirements as a dug
				  well.
(6) "Driven well" means a
				  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
				  pipe or sidewall placed in a well to prevent the walls from caving, or to seal
				  off surface drainage or undesirable water, gas, or other fluids so they cannot
				  enter the well;
(11) "Established
				  grade" means the elevation of the finished ground surface at the point of
				  intersection of the well casing;
(12) "Pollution" means the adverse effect on
				  water quality created by the introduction of any matter;
(13) "Sewer" means a conduit or pipe used or
				  intended for conveying sewage or other contaminated wastes, or such conduit or
				  pipe into which sewage or wastes may back up;
(14) "Source of pollution" means any place or
				  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;
(19)
				  "Public supply well" means a water supply well used or made available by a
				  water company to two or more consumers, as defined in section
				  25-32a
				  of the 1969 supplement to the general statutes.
