				water or liquids from being siphoned or pushed from back pressure into a water
				well.
"Casing" means the pipe installed in a drilled hole to give
				unobstructed access to a water-bearing formation and includes the riser pipe of
				a buried slab type dug or bored well.
"Chemical Injection System" means any device or combination of
				devices having hose, pipe or other methods of conveyance which connect directly
				to any water well through which a mixture of water, pesticides and fertilizer
				are mixed or are drawn and applied to land, crops, and/or plants at
				agricultural, nursery, turf, golf course, or greenhouse sites.
"Contamination" means a change of the biological, chemical, or
				physical quality of a water so that it is actually or potentially injurious or

"Finished Ground Surface" means the final or permanent
				elevation of the ground surface at the site of the well.
"Pipe Sleeve" means a pipe case in the cover slab of a dug or
				bored well to provide an entrance for pump components or use for venting,
				disinfection, or water level determination.
"Pitless Adapter Unit" means a factory assembled device
				consisting of the pitless adapter, a mechanism which attaches to the well
				casing, and a well casing riser in a single unit for the purpose of preventing
				contaminants from entering the well.
"Pitless Well Adapter" means an assembly of parts which will
				permit water to pass through the wall of the well casing or extension thereof;
				provides access to the well and to the parts of the water system within the
				well; and provides for the transportation of the water and the protection of
				the well and water therein, from surface or near surface contamination. Parts
				or appurtenances to a pitless well adapter include, but are not limited to, the
				vent, the device(s) on or in the wall of the casing, and the cap or cover on
				the top of the casing or casing extension.
"Pump Installation" means the procedure employed in the
				placement and preparation for operation of equipment and materials utilized in
				withdrawing or obtaining water from a well, including all construction involved
				in making entrance into the well and establishing such seals and safeguards as
				may be necessary to protect such water from contamination.
"Well Cap" means that portion of the pitless adapter used to
				enclose the atmospheric termination of the casing, which shall overlap the top
				of the casing extension with a downward flange.
"Water Well" means any excavation that is drilled, cored,

				materials utilized or intended for use in withdrawing or obtaining water from a
				well including pumps, seals, pressure tanks, fittings, and controls.
"Well Seal" means an arrangement or device used to establish a
				watertight closure at the junction of a well pump piping with the well casing
				cover at the upper terminal of the well, the purpose of which is to prevent
				contaminated water or other material from entering the well.
"Well Vent" means an opening at the upper terminal of a well to
				provide for equalization of air pressure in the well or the release of
				gases.
