A. 
Definitions. For the purpose of this chapter, the following definitions are established:
ADEQUATE WATER SUPPLY
Means that, where obtainable, the yield of a well or the capacity of a pump and distribution system shall be sufficient to meet the requirements which the user has stated are necessary for drinking, culinary and other purposes for which well water is intended to be used.
ANNULAR SPACE
The space between two circular objects, one of which surrounds the other, such as the opening between a drill hole and a casing pipe or between a casing pipe and a liner pipe.
APPROVED
Sanctioned by the Whitpain Board of Supervisors in conformity with applicable laws and regulations.
CONTAMINATION
Any matter which will render water unsafe for human consumption.
DRAWDOWN
The extent of lowering of the water level in a well when water flows or is pumped from it.
DRILL HOLE
(1) 
LOWER DRILL HOLEThat part of the drill hole below the vertical zone of contamination.
(2) 
UPPER DRILL HOLEThat part of a drill hole, auger hole or excavation established through the vertical zone of contamination.
DRIVEN-POINT WELL
A well constructed by joining a drive point with a length of pipe, extended as may be necessary, and driving the assembly into the ground without a preliminary excavation in excess of 10 feet in depth.
ESTABLISHED GRADE
The permanent point of contact of the ground or artificial surface with the casing pipe or curbing of the well.
ESTABLISHED GROUND SURFACE
The permanent elevation of the surface of the site of the well.
FLUSHING
The act of causing a rapid flow of water from a well by pumping, bailing or similar operation.
NEAR-SURFACE WATER
Water in the zone immediately below the ground surface. It may include seepage from barnyards, leaching pools and disposal beds or leakage from sewers, drains and similar sources of contaminated water.
PUMPING WATER LEVEL
That elevation of the surface of the water in a well when water flows or is pumped from it at a given rate.
SAFE WATER
Water that is sufficiently free from contamination to be safe for human ingestion in accordance with Pennsylvania State Health Code.
SANITARY CONDITION
(1) 
When referring to a well, it means that the construction of the well and the installation of the pumping equipment are such that the well is effectively protected against entrance of contaminating matter.
(2) 
When referring to the surroundings of a well, it means that the location and surrounding area are free from debris or filth of any character and not subject to flooding.
SEWER
A conduit used or intended for conveying sewage or other wastes.
SPECIFIC CAPACITY
The continuous yield of a well at a given drawdown expressed in gallons per minute per foot of drawdown.
STATIC WATER LEVEL
That elevation of the surface of the water in a well when no water flows or is being pumped therefrom.
STUFFING BOX
An approved receptacle in which packing may be compressed to form a water- or airtight junction between two objects.
VERTICAL ZONE OF CONTAMINATION
That depth of near-surface formations containing connecting pore spaces, crevices or similar openings, including artificial channels such as unprotected wells, through which contaminated water may gain access to a well or the groundwater body.
WATERTIGHT CONSTRUCTION
Implies cased and grouted construction through firm foundations like clay or rock. Through granular material like sand or gravel, it implies that the casing pipe is of approved quality and assembled watertight.
WELL SEAL
An approved removable arrangement or device used to cap a well or to establish and maintain a junction between the casing or curbing of a well and the piping or equipment installed therein so as to prevent water from entering the well at the upper terminal.
WELL VENT
An outlet at the upper end of the well casing to allow equalization of air pressure in the well.
YIELD
The quantity of water per unit of time which may flow or be pumped from a well at a constant specified drawdown.
B. 
Additional terms. The word "alteration" used in Section 4 of Ordinance 20[1] shall mean any change which increases pumping capacity or changes casing length. Normal repair or maintenance of well or pumping equipment is not included. For definitions of "board," "well," "well driller," "well drilling," "underground water capacity" and "person," see Section 1 of Ordinance 20.[2]
