Sec.  165.110  Bottled water.


    (a) Identity--(1) Description. Bottled water is water that is 
intended for human consumption and that is sealed in bottles or other 
containers with no added ingredients except that it may optionally 
contain safe and suitable antimicrobial agents. Fluoride may be 
optionally added within the limitations established in Sec.  
165.110(b)(4)(ii). Bottled water may be used as an ingredient in 
beverages (e.g., diluted juices, flavored bottled waters). It does not 
include those food ingredients that are declared in ingredient labeling 
as ``water,'' ``carbonated water,'' ``disinfected water,'' ``filtered 
water,'' ``seltzer water,'' ``soda water,'' ``sparkling water,'' and 
``tonic water.'' The processing and bottling of bottled water shall 
comply with applicable regulations in part 129 of this chapter.
    (2) Nomenclature. The name of the food is ``bottled water,'' 
``drinking water,'' or alternatively one or more of the following terms 
as appropriate:
    (i) The name of water from a well tapping a confined aquifer in 
which the water level stands at some height above the top of the aquifer 
is ``artesian water'' or ``artesian well water.'' Artesian water may be 
collected with the assistance of external force to enhance the natural 
underground pressure. On request, plants shall demonstrate to 
appropriate regulatory officials that the water level stands at some 
height above the top of the aquifer.
    (ii) The name of water from a subsurface saturated zone that is 
under a pressure equal to or greater than atmospheric pressure is 
``ground water.'' Ground water must not be under the direct influence of 
surface water as defined in 40 CFR 141.2.
    (iii) The name of water containing not less than 250 parts per 
million (ppm) total dissolved solids (TDS), coming from a source tapped 
at one or more bore holes or springs, originating from a geologically 
and physically protected underground water source, may be ``mineral 
water.'' Mineral water shall be distinguished from other types of water 
by its constant level and relative proportions of minerals and trace 
elements at the point of emergence from the source, due account being 
taken of the cycles of natural fluctuations. No minerals may be added to 
this water.
    (iv) The name of water that has been produced by distillation, 
deionization, reverse osmosis, or other suitable processes and that 
meets the definition of ``purified water'' in the United States 
Pharmacopeia, 23d Revision, January 1, 1995, which is incorporated by 
reference in accordance with 5 U.S.C. 551(a) and 1 CFR part 51. (Copies 
may be obtained from the United States Pharmacopial Convention, Inc., 
12601 Twinbrook Pkwy., Rockville, MD 20852 and may be examined at the 
Center for Food Safety and Applied Nutrition's Library, 5100 Paint 
Branch Pkwy., College Park, MD 20740, or at the National Archives and 
Records Administration (NARA). For information on the availability of 
this material at NARA, call 202-741-6030, or go to: http://
www.archives.gov/federal--register/code--of--federal--regulations/ibr--
locations.html.), may be ``purified water'' or ``demineralized water.'' 
Alternatively, the water may be called ``deionized water'' if the water 
has been processed by deionization, ``distilled water'' if it is 
produced by distillation, ``reverse osmosis water'' if the water has 
been processed by reverse osmosis, and ``------ drinking water'' with 
the blank being filled in with one of the defined terms describing the 
water in this paragraph (e.g., ``purified drinking water'' or 
``deionized drinking water'').
    (v) The name of water that, after treatment and possible replacement 
of carbon dioxide, contains the same amount of carbon dioxide from the 
source that it had at emergence from

[[Page 524]]

the source may be ``sparkling bottled water.''
    (vi) The name of water derived from an underground formation from 
which water flows naturally to the surface of the earth may be ``spring 
water.'' Spring water shall be collected only at the spring or through a 
bore hole tapping the underground formation feeding the spring. There 
shall be a natural force causing the water to flow to the surface 
through a natural orifice. The location of the spring shall be 
identified. Spring water collected with the use of an external force 
shall be from the same underground stratum as the spring, as shown by a 
measurable hydraulic connection using a hydrogeologically valid method 
between the bore hole and the natural spring, and shall have all the 
physical properties, before treatment, and be of the same composition 
and quality, as the water that flows naturally to the surface of the 
earth. If spring water is collected with the use of an external force, 
water must continue to flow naturally to the surface of the earth 
through the spring's natural orifice. Plants shall demonstrate, on 
request, to appropriate regulatory officials, using a hydrogeologically 
valid method, that an appropriate hydraulic connection exists between 
the natural orifice of the spring and the bore hole.
    (vii) The name of water that meets the requirements under 
``Sterility Tests'' <71 in the United States Pharmacopeia, 
23d Revision, January 1, 1995, which is incorporated by reference in 
accordance with 5 U.S.C. 552(a) and 1 CFR 51. (Copies may be obtained 
from the United States Pharmacopeial Convention, Inc., 12601 Twinbrook 
Pkwy., Rockville, MD 20852 and may be examined at the Center for Food 
Safety and Applied Nutrition's Library, 5100 Paint Branch Pkwy., College 
Park, MD 20740, or at the National Archives and Records Administration 
(NARA). For information on the availability of this material at NARA, 
call 202-741-6030, or go to: http://www.archives.gov/federal--register/
code--of--federal--regulations/ibr--locations.html.), may be ``sterile 
water.'' Alternatively, the water may be called ``sterilized water.''
    (viii) The name of water from a hole bored, drilled, or otherwise 
constructed in the ground which taps the water of an aquifer may be 
``well water.''
    (3) Other label statements. (i) If the TDS content of mineral water 
is below 500 ppm, or if it is greater than 1,500 ppm, the statement 
``low mineral content'' or the statement ``high mineral content'', 
respectively, shall appear on the principal display panel following the 
statement of identity in type size at least one-half the size of the 
statement of identity but in no case of less than one-sixteenth of an 
inch. If the TDS of mineral water is between 500 and 1,500 ppm, no 
additional statement need appear.
    (ii) When bottled water comes from a community water system, as 
defined in 40 CFR 141.2, except when it has been treated to meet the 
definitions in paragraphs (a)(2)(iv) and (a)(2)(vii) of this section and 
is labeled as such, the label shall state ``from a community water 
system'' or, alternatively, ``from a municipal source'' as appropriate, 
on the principal display panel or panels. This statement shall 
immediately and conspicuously precede or follow the name of the food 
without intervening written, printed, or graphic matter, other than 
statements required by paragraph (c) of this section, in type size at 
least one-half the size of the statement of identity but in no case of 
less than one-sixteenth of an inch.
    (iii) When the label or labeling of a bottled water product states 
or implies (e.g., through label statements or vignettes with references 
to infants) that the bottled water is for use in feeding infants, and 
the product is not commercially sterile under Sec.  113.3(e)(3)(i) of 
this chapter, the product's label shall bear conspicuously and on the 
principal display panel the statement ``Not sterile. Use as directed by 
physician or by labeling directions for use of infant formula.''
    (4) Label declaration. Each of the ingredients used in the food 
shall be declared on the label as required by the applicable sections of 
parts 101 and 130 of this chapter.
    (b) Quality. The standard of quality for bottled water, including 
water for use as an ingredient in beverages (except those described in 
the labeling as

[[Page 525]]

``water,'' ``carbonated water,'' ``disinfected water,'' ``filtered 
water,'' ``seltzer water,'' ``soda water,'' ``sparkling water,'' and 
``tonic water''), is as follows:
