Advice for people with
severely compromised
immune systems
Some people may wish to take
special precautions with the water
they drink In particular, people
with immune systems that are
weakened by AIDS, chemothera-
py or transplant medications are
more vulnerable to microbial con-
taminants in drinking water such
as Cryptosporidiim.
Cryptosporidium is a microscopic
parasite that lives in the intestine of
infected animals and humans. It
passes in the stool in its dormant
oocyst fbrm.The oocyst is protect-
ed by an outer shell that allows it
to survive outside the body for
long periods of time and makes it
very resistant to chlorine-based
disinfectants. It occurs mainly in
surface water sources, such as
lakes, streams and rivers. In healthy
adults, Cryptosporidium can cause ill-
ness, but for people with weakened
immune systems, it can cause
severe illness and even death.
Those who wish to take extra
measures to avoid waterborne
cryptosporidiosis can bring their
drinking water to a boil for a full
minute. Boiling water is the
most effective way of killing
Cryptasporidium.As an alterna-
tive to boiling water, people may
take the following measures:
Use a poinbof-use filter

Bott/ed water basics
Bottled water is the fastest growing drink choice
in the United States, and Americans spend bil-
lions of dollars each year to buy it (Beverage
Marketing Corporation, 2004) Some people
drink bottled water as an alternative to other
beverages; others drink it because they prefer its
taste or think it is safer than their tap water.
Whether it travels through a pipe to your home or
comes packaged in a bottle, safe drinking water is
essential to good health. All our drinking water
comes from similar sources, either from sources we
can see, such as rivers and lakes, or from sources
we can't see, such as underground aquifers.
In the same way that tap water's taste and quality
may vary from place to place, so too does bottled
water's taste and quality vary among and even
within brands.The taste and quality of both bot-
tled water and tap water depend on the source
and quality of the water, including its natural
mineral content and how, or if, the water is treated.
Drinking water (both bottled and tap) can rea-
sonably be expected to contain at least small
amounts of some contaminants.The presence of
contaminants does not necessarily indicate that
the water poses a health risk. For example, min-
erals such as magnesium and calcium give water
a distinctive flavor, and are essential to the body.
At high levels, however, these and other contami-
nants, such as pesticides or microbes from human
wastes, can cause adverse effects or illness.
To make sure that all water is safe to drink, the
U.S. Environmental Protection Agency (EPA) and
the U.S. Food and Drug Administration (FDA) set
drinking water standards. EPA sets standards for tap

sonal use, end-of-tap, under sink)
filters that remove particles one
micrometer or less in diameter
Filters that use reverse osmosis,
those labeled as "absolute one
micron filters," or those labeled as
certified by an American National
Standards Institute (ANSI) -
accredited organization to
ANSI/NSF Standard 53 for "Cyst
Removal" provide the greatest
assurance of removing
Cryptosporidium.As with all filters,
follow the manufacturer's instruc-
tions for filter use and replace-
ment
Use battled water
Check the label or call the bottler
to find out how bottled water is
treated. The following bottled
water treatments protect against
Ctyptosporidum: reverse osmosis,
distillation, ultraviolet light, or filtra-
tion with an absolute one micron
filter. Bottled waters derived from
protected well and spring water
sources are less likely to be con-
taminated by Cryptosporidiim than
those containing untreated munic-
ipal drinking water from less pro-
tected sources such as rivers and
lakes.
Those who choose to take these
precautions should remember
that they can be exposed to
waterbome pathogens through
water used for brushing teeth,
making ice cubes, and washing
fruits and vegetables - not just
through water they drink
water provided by public water suppliers; FDA sets
standards for bottfed water based on EPA standards.
Bottfed water and tap water are both safe to drink if
they meet these standards, although people with
severely weakened immune systems or other specific
health conditions may wish to further treat tfte/'r water
at home or purchase high quality bottfed water.
FDA regulates bottled water as a packaged food
under the Federal Food, Drug and Cosmetic Act
and has established standards of identity and
quality for bottled water. FDA has also established
good manufacturing practice requirements for
processing and bottling drinking water.
EPA encourages all Americans to learn more about
the quality of their drinking water, both tap water
and bottled water, before deciding whether to
drink tap water, bottled water, or both. If your
water comes from a public water system, the best
way to learn more about tap water is to read your
water supplier's annual water quality report. If
your water comes from a household well, EPA rec-
ommends testing the water regularly for bacteria,
nitrates, and other contaminants.The best way to
learn more about bottled water is to read its label,
or contact the producer directly.
Know what you're buying
Bottled water is much more expensive, per gallon,
than tap water. Because of this, consider whether
you are buying it as a healthy alternative to bottled
beverages, for its taste, or for other reasons.

Bottled Water Terms
The following terms are fre-
quently used on bottled
water labels to describe the
water's characteristics,
sources, and methods of
treatment.
Artesian water, ground
water, spring water, well
water - water from an under-
ground aquifer which may or
may not be treated. Well
water and artesian water are
tapped through a well. Spring
water is collected as it flows
to the surface or via a bore-
hole. Ground water can be
either.
Distilled water - steam from
boiling water is recondensed
and bottled. Distilling water
kills microbes and removes
water's natural minerals, giv-
ing it a flat taste.
Drinking water - water
intended for human consump-
tion and sealed in bottles or
other containers with no
ingredients except that it may
optionally contain safe and
suitable disinfectants. Fluoride
may be added within limita-
tions set in the bottled water
quality standards.
Mineral water - Ground
water that naturally contains
250 or more parts per million
of total dissolved solids.
Taste considerations
Many people prefer
bottled water
because of its taste.
The taste of all water
has to do with the way
it is treated and the
quality of its source,
including its natural
mineral content Most
boated water comes
from a ground water
source, where water
quality varies less from
day to day, or is treat-
ed and immediately bottled. Bottled water from a ded-
icated source or plant may have a more consistent
taste than tap water, which mostly comes from sur-
face sources and must travel through pipes to reach
homes.
One of the key taste differences between tap water
and boated water is due to how the water is disinfec-
ted.Tap water may be disinfected wtth chlorine, chlo-
ramine, ozone, or ultraviolet light to kill disease

Purified water - water that
originates from any source
but has been treated to meet
the U.S.
Pharmacopeia
definition of
purified water.
Purified water is
essentially free
of all chemicals
(it must not
contain more
than 10 parts
per million of
total dissolved
solids), and may
also be free of
microbes if
treated by dis-
tillation or reverse osmosis.
Purified water may alternately
be labeled according to how
it is treated.
Sterile water - water that
originates from any source,
but has been treated to meet
the U.S. Pharmacopeia stan-
dards for sterilization.
Sterilized water is free from
all microbes.
Note: Carbonated water,
soda water, seltzer water,
sparkling water, and tonic
water are considered soft
drinks and are not regulated
as bottled water.
Begin by reading the label
To learn about the quality of bottled water,
begin by reading the label. In addition to the
volume of water, any pertinent nutritional claims,
and any contact information for the bottler, the
label may include the type of bottled water, its
source, and the way in which it is treated. For
more specific information, you may need to
contact the bottler directly.
Type of water and source:
Bottlers use standard identifiers, prescribed by
FDA regulations, to describe their water (Bottled
water terms, pgs 4 and 5), but the meanings
may be different than you expect These terms refer to
both the geological sources of the water and the
treatment methods applied to the water. Trie
terms don't necessarily describe the geographic
location of the source or determine its quality.
For instance,"spring water"can be collected at the
point where water flows naturally to the earth's surface
or from a borehole that taps into the underground
source. Other terms used on the label about the
source, such as "glacier water" or "mountain water"
are not regulated standards of identity and may not
indicate that the water is necessarily from a pristine
area. Likewise, the term, "purified," refers to processes
that remove chemicals and pathogens. "Purified
water" is not necessarily free of microbes - though it
may be.

Common Bottled Water
Treatments
Distillation - water is boiled,
and the steam is condensed
to remove salts, metals, min-
erals, asbestos, particles, and
some organic materials.
Microbes are killed, including
Cryptosporidium.
Micron Filtration - water is
filtered through screens with
microscopic holes. The small-
er the filter holes, the more
contaminants the filter can
remove. Good filters can
remove most chemical con-
taminants and microbes.
Filter holes are measured in
microns. (The period at the
end of this sentence is 500
microns.) When considering
BoHfed water must be tested and meet regulatory stan-
dards before it can be sold in the US. (See page 8 for
details.) Bottfed water, like tap water, can come from a
ground water source, such as a well or spring or a sur-
face water source, such as a river or stream. Most bot-
tled water comes from a ground water source. Ground
water is typically less vulnerable to contamination than
water from surface sources. However, ground water can
still contain naturally high amounts of certain contami-
nants, including radioactive e/ements, arsenic, and
nitrates, or be vulnerable to contamination from human
activities, such as industrial waste, faulty septic systems,
and underground gas or chemical tanks.
Some boflfed water comes from surface water
sources. This water typically comes from a public
water system and receives additional treatment, such
as filtration and disinfection, before it is bottled.
BoHfers must list on the label the type of bottfed water
(such as spring water, mineral water, or drinking water). If
the water comes from a public water system and has not
been treated to meet FDA's definition of "purified" or
"sterile" water, the label must state that the source is from
a community water system.
Contaminants and methods of
treatment:
/f you are concerned about a particular contaminant in
your drinking water, consider the following questions: Is
the source water likely to contain the contaminant? Has
the water been treated to remove the contaminant?
Water that originates from a protected ground water
source is less likely to contain certain contaminants
(such as disease
-------
filter size, look for an
absolute (the largest hole),
not nominal (the average
hole) rating. An absolute one
micron filter is needed to
remove Cryptosporidium.
Ozonation - water is disin-
fected using ozone, which
kills most microbes, depend-
ing on dosage applied.
Reverse Osmosis - water is
forced under pressure to
pass through a membrane,
leaving contaminants behind.
This process removes all
microbes, minerals, color, tur-
bidity, organic and inorganic
chemicals.
Ultraviolet (UV) light -
water is passed through UV
light, which kills most
microbes, depending on
dosage applied.
The best way to know if the water you are drink-
ing is free from the contaminant(s) you are con-
cerned about is to contact the bottler and ask for
the latest testing results and whether the water
has been treated to remove the contaminant.
Many public water systems add fluoride to their
water; most bottlers do not tf bottled water is fluoridat-
ed, it must indicate so on the label, though bottfed
water and tap water can contain naturally occurring
fluoride. Check wtth your public water system or bottler
to find out if the water you drink contains fluoride.
Certification
Neither EPA nor FDA certify bottfed water. However,
consumers may notice a logo or seal from two other
organizations on the label.
The International Bofl/ed Water Association (IBWA) is a trade
organization for water battlers. IBWA members must meet trie
organization's "model code" and are subject to annual inspec-
tions by an independent ihird party. Bottlers belonging to
IBWA frequently indicate membership on iheir labels.
NSF International - Bottfed water certified by NSF under-
goes additional testing by unannounced annual plant
inspections. NSF certifications mean that the bottler
complies with all applicable FDA requirements, includ-
ing good manufacturing practices.
Underwriters Laboratories, Inc. (UL) is an independent
accredited testing and certification organization that
tests boflfed water to FDA state, and IBWA model code
requirements.
If you use a water cooler, remember to
dean and sanitize it regularly according
to the manufacture's instructions.

FDA Bottled Water
Standards
Any bottled water sold in
interstate commerce in the
United States including prod-
ucts that originate overseas
must meet the following mini-
mum federal standards (check
with your health department
to see what bottled water
standards exist for brands
produced, bottled, and sold
entirely in one state):
Bottled water must meet FDA
standards for physical, chemi-
cal, microbial, and radiological
contaminants.When EPA sets a
new standard for a contami-
nant in tap water, FDA must
establish a new standard for
the same contaminant in bot-
tled water or find that EPA's
new standard is not applicable
to bottled water.
Bottlers must include the
name of the product and type
of water; the name and address
of the manufacturer, packer, or
distributor; and the net con-
tent on their labels.
New bottled water sources
must be approved by a state or
local jurisdiction. Bottlers must
also test their sources and fin-
ished bottled water products
For more information on bottled water:
Contact #7e bottler directly, ask for its latest testing
results, and compare these results wtth EPA's tap water
standards (www.epa.gov/safewater/mcl.html) or FDA's
bottled water standards to determine its quality.

If bottled water is found to
be adulterated or hazardous
to health, it is subject to FDA
enforcement action, such as
seizure of domestic products
and refusal of entry of
imports.
Bottlers must operate their
plants in accordance with
FDA's good manufacturing
practices to ensure that their
bottled water products are
safe and produced under safe
and sanitary conditions.
