"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 harmful to the health of the user.
"Department" means the Illinois Department of Public Health.
"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.
