				  permanently discontinued; has had its pumping equipment permanently removed; is
				  in such a state of disrepair that it cannot be used to supply water and/or has
				  the potential for transmitting surface contaminants into the aquifer; poses
				  potential health or safety hazards or the well is in such a condition that it

				  normally used.
Average Daily Demand during the Month of Maximum
				  Water Use-

Back Siphonage
- a form of backflow caused by
				  negative or subatmospheric pressure within a water system.
Backflow
-
a. a flow condition, induced by a
				differential pressure, that causes the flow of water or other liquid into the
				distribution pipes of a potable water supply from any source or sources other
				than its intended source; or
b. the
				backing up of water through a conduit or channel in the direction opposite to
				normal flow.
Backflow Preventer

				  water supply pipe to prevent the backflow of water of questionable quality into
				  the potable water supply system.
Boil Notice

				  requesting certification.
Laboratory Requesting Certification
- an
				  uncertified laboratory which has submitted an acceptable application and
				  appropriate fee(s) for the category in which it desires certification.
Lead Free
-
a. In general.
i. not containing more than 0.2 percent lead
				when used with respect to solder and flux; and
ii. not more than a weighted average of 0.25
				percent lead when used with respect to the wetted surfaces of pipes, pipe
				fittings, plumbing fittings, and fixtures.
b. Calculation
i. The weighted average lead content of a
				pipe, pipe fitting, plumbing fitting, or fixture shall be calculated by using
				the following formula:
(a). For each wetted
				component, the percentage of lead in the component shall be multiplied by the
				ratio of the wetted surface area of that component to the total wetted surface
				area of the entire product to arrive at the weighted percentage of lead of the
				component. The weighted percentage of lead of each wetted component shall be
				added together, and the sum of these weighted percentages shall constitute the
				weighted average lead content of the product. The lead content of the material
				used to produce wetted components shall be used to determine compliance with
				Clause "a.ii." above. For lead content of materials that are provided as a
				range, the maximum content of the range shall be used.
Level 1 Assessment
-an evaluation to identify
				  the possible presence of sanitary defects, defects in distribution system
				  coliform monitoring practices, and (when possible) the likely reason that the
				  system triggered the assessment. Minimum elements include review and
				  identification of atypical events that could affect distributed water quality
				  or indicate that distributed water quality was impaired; changes in
				  distribution system maintenance and operation that could affect distributed
				  water quality (including water storage); source and treatment considerations
				  that bear on distributed water quality, where appropriate; existing water
				  quality monitoring data; and inadequacies in sample sites, sampling protocol,
				  and sample processing. The system must conduct the assessment consistent with
				  any State directives that tailor specific assessment elements with respect to
				  the size and type of the system and the size, type, and characteristics of the
				  distribution system.
Level 2 Assessment
-an evaluation to identify
				  the possible presence of sanitary defects, defects in distribution system
				  coliform monitoring practices, and (when possible) the likely reason that the
				  system triggered the assessment. A Level 2 assessment provides a more detailed
				  examination of the system (including the system's monitoring and operational
				  practices) than does a Level 1 assessment through the use of more comprehensive
				  investigation and review of available information, additional internal and
				  external resources, and other relevant practices. Minimum elements include
				  review and identification of atypical events that could affect distributed
				  water quality or indicate that distributed water quality was impaired; changes
				  in distribution system maintenance and operation that could affect distributed
				  water quality (including water storage); source and treatment considerations
				  that bear on distributed water quality, where appropriate; existing water
				  quality monitoring data; and inadequacies in sample sites, sampling protocol,
				  and sample processing. The system must comply with any expedited actions or
				  additional actions required by the State in the case of an
E.
				  coli
MCL violation.
Listed
-equipment or materials included in a
				  list published by an approved nationally recognized testing laboratory,
				  inspection agency or other organization concerned with product evaluation that
				  maintains periodic inspection of production of
listed
equipment or materials, and whose listing states either that the equipment or
				  material meets nationally recognized standards or has been tested and found
				  suitable for use in a specified manner. The means for identifying
listed
equipment may vary for each testing laboratory,
				  inspection agency, or other organization concerned with product evaluation,
				  some of which do not recognize equipment as
listed
unless it
				  is also labeled. The water supplier should utilize the system employed by the
				  listing organization to identify a
listed
product.
a. In respect to any solder, flux, pipes,
				pipe fittings, plumbing fittings, fixtures, and any other appurtenances which
				are claimed to be lead free, this defined term (listed) shall additionally
				include the requirement that all such solder, flux, pipes, pipe fittings,
				plumbing fittings, fixtures, and any other appurtenances have been certified to
				be lead free by an independent American National Standards Institute
				(ANSI)-accredited third party testing laboratory, inspection agency or other
				organization concerned with product evaluation.
