Plastic
Bottle Facts:
•
Visualize the average energy cost to make a plastic bottle, process and fill
the bottle, transport the bottled water to market and then deal with the waste:
It would be like filling up a quarter of every bottle with oil.
•
Bottle water costs about 1000 times more than tap water.
• 40%
of bottled water starts as tap water.
• 86%
of plastic water bottles used in the U.S. end up in landfills, where they will
take up to 1,000 years to biodegrade.
• 47
million gallons of oil is consumed to produce the bottles that Americans drink
out of each year. This is enough oil to take 100,000 cars off the road and
1-billion pounds of carbon dioxide out of the atmosphere.
• The
federal standards for tap water are higher than those for bottled water.
• The
energy we waste using bottled water would be enough to power 190,000 homes. But
refilling your water bottle from the tap requires no expenditure of energy, and
zero waste of resources.
•
Bottled water is often not of high water quality.
• In a
study conducted by the National Resources Defense Council one third of bottled
water tested contained significant contamination.
• The
U.S. Food and Drug Administration (FDA) do not regulate 60-70 percent of bottled
water.
• For
the 30-40 percent it does regulate, the FDA only requires companies to test a
sample of water once per week.
• The
EPA requires testing of municipal water systems between 300-480 times per month
• The
shipment of bottled water burns massive quantities of fossil fuel, a weekly
convoy of 37,000 18- wheelers.
• The
incineration of the plastic bottles releases toxic byproducts such as chlorine
gas and ash laden with heavy metals into the air.
•
Approximately 18 million barrels of crude oil equivalent were consumed in 2005
to replace the 2 million tons of PET bottles that were wasted instead of
recycled.
• The
world's annual consumption of plastic materials has increased from around 5
million tons in the 1950s to nearly 100 million tons today.

Bottled
Water
Learning the Facts and
Taking Action
Unnecessary
consumption of drinking water in plastic bottles is wasteful and damaging to the
environment. Millions of plastic bottles are not recycled and end up in
landfills, in parks and along roadways. Nine out of ten plastic water bottles
end up as garbage or litter. That’s 30 million discarded plastic bottles each
day— more than 10 billion a year. Large amounts of energy is consumed in
manufacture, transportation, and recycling of the bottles.
Most smaller bottles
are made from polyethylene terephthalate (PET). PET is a petroleum product that
generates more than 100 times more toxic emissions than an equivalent amount of
glass, according to the Berkeley Ecology Center. Because plastic bottles are
presently recycled at such low rates, tens of billions of new plastic bottles
must be manufactured each year from virgin materials— fossil fuels—to replace
those bottles that were not recycled. When PET plastic bottles are made from
virgin materials rather than used bottle resin, more greenhouse gases are
produced as well. An estimated 800 thousand metric tons of carbon equivalent
(MTCE) were released in the process of making approximately 50 billion new PET
bottles from virgin rather than recycled materials.
Leaching of
chemicals into the water is also a concern. “Eight of the ten 5-gallon
polycarbonate jugs that the Sierra Club’s water task force checked left residues
of the endocrine disrupter, bisphenol A, in the water”(Consumer Reports 8/00).
More research is needed regarding leaching of harmful chemicals from all types
of plastic bottles. Leaching increases with heat, raising concern about storage
and transportation of the bottles. No problems have been associated with
refillable stainless steel containers.
Bottled water is
regulated by the Food and Drug Administration, which has weaker regulations than
the EPA regulations for tap water. (“What’s in that Bottle?” Consumer Reports
1/03.) Bottled water sold within states is regulated only by state
agencies. NRDC (National Resources Defense Council) tested more than 1,000
bottles of 103 brands of bottled water. They found contamination exceeding
allowable limits in at least one sample from about one-third of the brands,
including synthetic organics, bacteria, and arsenic. (The NRDC report follows
this article)
The bottled water
industry promotes bottled water as a healthy, trendy drink, without mentioning
that it can cost 1,000 times as much as tap water. All people should have access
to affordable, clean drinking water. This means protecting water sources and
funding for upgrading municipal systems should be a national priority. If you
are concerned about the quality or taste of your tap water, it is much cheaper
to install a water filter on your tap to remove the pollutants than to depend on
bottled water.
Having created a
growing market for bottled water, transnational corporations are exercising
their power to get access to springs, aquifers, and municipal water supplies to
keep their profits flowing, with little regard for the environmental impacts of
large water withdrawals. Nestlé has taken over many small, independent
companies, set up much larger operations at local springs, and is aggressively
pursuing new sites around the Unites States. Coke’s Dasani and Pepsi’s Aquafina
brands depend on cheap municipal water in the United States. Coke’s bottled
water operation in India is embroiled in controversy, where a “ Boycott Coke”
campaign is underway.
Growth in the
bottled water market not only undermines public confidence in the government’s
ability to provide basic services, but it also increases municipal government
waste disposal costs. Last year, at least four billion pounds of plastic bottles
ended up in city waste streams. It can cost cities more than $70 million in
disposal fees, not including the costs of collection, trucking and litter
removal

National Resources Defense Council
Report on Bottled Water
Pure Drink or Hype?
EXECUTIVE SUMMARY
More than
half of all Americans drink bottled water; about a third of the public consumes
it regularly. Sales have tripled in the past 10 years, to about $4 billion a
year. This sales bonanza has been fueled by ubiquitous ads picturing towering
mountains, pristine glaciers, and crystal-clear springs nestled in untouched
forests yielding absolutely pure water. But is the marketing image of total
purity accurate? Also, are rules for bottled water stricter than those for tap
water?
Not exactly. No one should assume that just because he or she purchases water in
a bottle that it is necessarily any better regulated, purer, or safer than most
tap water. NRDC has completed a four-year study of the bottled water industry,
including its bacterial and chemical contamination problems. We have conducted a
review of available information on bottled water and its sources, an in-depth
assessment of Food and Drug Administration (FDA) and all 50 states' programs
governing bottled water safety, and an analysis of government and academic
bottled water testing results. We have compared FDA's bottled water rules with
certain international bottled water standards and with the U.S. Environmental
Protection Agency (EPA) rules that apply to piped tap water supplied by public
water systems. In addition, NRDC commissioned independent lab testing of more
than 1,000 bottles of 103 types of bottled water from many parts of the country
(California, the District of Columbia, Florida, Illinois, New York, and Texas).
Our conclusions and recommendations follow.
An Exploding Bottled Water Market
• There has been an explosion in bottled water use in the United
States, driven in large measure by marketing designed to convince the public of
bottled water's purity and safety, and capitalizing on public concern about tap
water quality. People spend from 240 to over 10,000 times more per gallon for
bottled water than they typically do for tap water.
• Some
of this marketing is misleading, implying the water comes from pristine sources
when it does not. For example, one brand of "spring water" whose label pictured
a lake and mountains actually came from a well in an industrial facility's
parking lot, near a hazardous waste dump, and periodically was contaminated with
industrial chemicals at levels above FDA standards.
•
According to government and industry estimates, about one fourth of bottled
water is bottled tap water (and by some accounts, as much as 40 percent is
derived from tap water) -- sometimes with additional treatment, sometimes not.
Major Regulatory Gaps
• FDA's rules completely exempt 60-70 percent of the bottled water
sold in the United States from the agency's bottled water standards, because FDA
says its rules do not apply to water packaged and sold within the same state.
Nearly 40 states say they do regulate such waters (generally with few or no
resources dedicated to policing this); therefore, about one out of five states
do not.
• FDA
also exempts "carbonated water," "seltzer," and many other waters sold in
bottles from its bottled water standards, applying only vague general sanitation
rules that set no specific contamination limits. Fewer than half of the states
require these waters to meet bottled water standards.
• Even
when bottled waters are covered by FDA's specific bottled water standards, those
rules are weaker in many ways than EPA rules that apply to big city tap water.
For instance, comparing those EPA regulations (for water systems which serve the
majority of the U.S. population) with FDA's bottled water rules:
o City tap water
can have no confirmed E. coli or fecal coliform bacteria (bacteria that are
indications of possible contamination by fecal matter). FDA bottled water rules
include no such prohibition (a certain amount of any type of coliform bacteria
is allowed in bottled water).
o City tap water
from surface water must be filtered and disinfected (or the water system must
adopt well-defined protective measures for the source water it uses, such as
control of potentially polluting activities that may affect the stream
involved). In contrast, there are no federal filtration or disinfection
requirements for bottled water -- the only source-water protection, filtration,
or disinfection provisions for bottled water are completely delegated to state
discretion, and many states have adopted no such meaningful programs.
o Bottled water
plants must test for coliform bacteria just once a week; big-city tap water must
be tested 100 or more times a month.
o Repeated high
levels of bacteria (i.e., "heterotrophic-plate-count" bacteria) in tap water
combined with a lack of disinfectant can trigger a violation for cities -- but
not for water bottlers.
o Most cities
using surface water have had to test for Cryptosporidium or Giardia, two common
water pathogens that can cause diarrhea and other intestinal problems (or more
serious problems in vulnerable people), yet bottled water companies don't have
to do this.
o City tap water
must meet standards for certain important toxic or cancer-causing chemicals such
as phthalate (a chemical that can leach from plastic, including plastic
bottles); some in the industry persuaded FDA to exempt bottled water from
regulations regarding these chemicals.
o Any violation
of tap-water standards is grounds for enforcement -- but bottled water in
violation of standards can still be sold if it is labeled as "containing
excessive chemicals" or "excessive bacteria" (unless FDA finds it "adulterated,"
a term not specifically defined).
o Cities
generally must test at least once a quarter for many chemical contaminants.
Water bottlers generally must test only annually.
o Cities must
have their water tested by government-certified labs; such certified testing is
not required for bottlers.
o Tap water test
results and notices of violations must be reported to state or federal
officials. There is no mandatory reporting for water bottlers.
o City water
system operators must be certified and trained to ensure that they know how to
safely treat and deliver water -- not so for bottlers.
o City water
systems must issue annual "right-to-know" reports telling consumers what is in
their water; as detailed in this report, bottlers successfully killed such a
requirement for bottled water.
• FDA and state
bottled water programs are seriously underfunded. FDA says bottled water is a
low priority; the agency estimates it has the equivalent of fewer than one staff
person dedicated to developing and issuing bottled water rules, and the
equivalent of fewer than one FDA staffer assuring compliance with the bottled
water rules on the books. Although a small number of states (such as California)
have real bottled water programs, our 1998 survey found that 43 states have
fewer than one staff person dedicated to bottled water regulation. By
comparison, hundreds of federal staff and many more state personnel are
dedicated to tap water regulation. Directing disproportionate resources to tap
water protection is warranted. At the same time, over half the U.S. public
(including many immunocompromised people) uses bottled water, and many millions
of people use bottled water as their chief or exclusive drinking water source.
• FDA's
regulations are less stringent than some international standards. For example,
unlike FDA's rules, the European Union's (EU's) bottled natural mineral water
standards regulate total bacteria count, and explicitly ban all parasites and
pathogenic microorganisms, E. coli or other coliform bacteria, fecal
streptococci (e.g., Streptococcus faecalis, recently renamed Enterococcus
faecalis), Pseudomonas aeruginosa, and sporulated sulphite-reducing anaerobic
bacteria. Moreover, unlike the weaker FDA rules, the EU rules require natural
mineral bottled water's labels to state the composition of the water and the
specific water source, and mandate that only one water label may be used per
source of water. Similarly, recent EU standards applicable to all bottled water
also are far stricter than FDA standards. FDA's standards for certain chemicals
(such as arsenic) also are weaker than certain World Health Organization (WHO)
guidelines.
Bottled Water: As Pure as
We Are Led to Believe?
• While
most bottled water apparently is of good quality, publicly available monitoring
data are scarce. The under funded and haphazard patchwork of regulatory programs
has found numerous cases where bottled water has been contaminated at levels
above state or federal standards. In some cases bottled water has been recalled.
• Our "snapshot"
testing of more than 1,000 bottles of 103 brands of water by three independent
labs found that most bottled water tested was of good quality, but some brands'
quality was spotty. About one third of the bottled waters we tested contained
significant contamination (i.e., levels of chemical or bacterial contaminants
exceeding those allowed under a state or industry standard or guideline) in at
least one test. This is the most comprehensive independent testing of bottled
water in the United States that is publicly available. Moreover, NRDC contracted
with an independent data verification firm to confirm the accuracy of our
positive test results. Still, the testing was limited. The labs tested most
waters for about half of the drinking water contaminants regulated by FDA (to
control costs). They found:
o Nearly one in
four of the waters tested (23 of the 103 waters, or 22 percent) violated strict
applicable state (California) limits for bottled water in at least one sample,
most commonly for arsenic or certain cancer-causing man-made ("synthetic")
organic compounds. Another three waters sold outside of California (3 percent of
the national total) violated industry-recommended standards for synthetic
organic compounds in at least one sample, but unlike in California, those
industry standards were not enforceable in the states (Florida and Texas) in
which they were sold.
o Nearly one in
five tested waters (18 of the 103, or 17 percent) contained, in at least one
sample, more bacteria than allowed under microbiological-purity "guidelines"
(unenforceable sanitation guidelines based on heterotrophic plate count [HPC]
bacteria levels in the water) adopted by some states, the industry, and the EU.
The U.S. bottled water industry uses HPC guidelines, and there are European HPC
standards applicable overseas to certain bottled waters, but there are no U.S.
standards in light of strong bottler opposition to making such limits legally
binding.
o In sum,
approximately one third of the tested waters (34 of 103 waters, or 33 percent)
violated an enforceable state standard or exceeded microbiological-purity
guidelines, or both, in at least one sample. We were unable to test for many
microbial contaminants, such as Cryptosporidium, because the logistics and cost
of testing for them post-bottling were beyond our means.
o Four waters (4
percent) violated the generally weak federal bottled water standards (two for
excessive fluoride and two for excessive coliform bacteria; neither of the two
latter waters were found to be contaminated with coliform bacteria in our
testing of a different lot of the same brand).
o About one fifth
of the waters contained synthetic organic chemicals -- such as industrial
chemicals (e.g., toluene or xylene) or chemicals used in manufacturing plastic
(e.g., phthalate, adipate, or styrene) -- in at least one sample, but generally
at levels below state and federal standards. One sample contained phthalate -- a
carcinogen that leaches from plastic -- at a level twice the tap water standard,
but there is no bottled water standard for this chemical; two other samples from
different batches of this same water contained no detectable phthalate.
o In addition,
many waters contained arsenic, nitrates, or other inorganic contaminants at
levels below current standards. While in most cases the levels found were not
surprising, in eight cases arsenic was found in at least one test at a level of
potential health concern.
o For purposes of
comparison, we note that EPA recently reported that in 1996 about 1 in 10
community tap water systems (serving about one seventh of the U.S. population)
violated EPA's tap water treatment or contaminant standards, and 28 percent of
tap water systems violated significant water-monitoring or reporting
requirements. In addition, the tap water of more than 32 million Americans (and
perhaps more) exceeds 2 parts per billion (ppb) arsenic (the California
Proposition 65 warning level, applicable to bottled water, is 5 ppb); and 80 to
100 million Americans drink tap water that contains very significant
trihalomethane levels (over 40 ppb). Thus, while much tap water is supplied by
systems that have violated EPA standards or that serve water containing
substantial levels of risky contaminants, apparently the majority of the
country's tap water passes EPA standards. Therefore, while much tap water is
indeed risky, having compared available data we conclude that there is no
assurance that bottled water is any safer than tap water.
• Other academic
and government bottled water surveys generally are consistent with the testing
NRDC commissioned. Though usually limited in scope, these studies also have
found that most bottled water meets applicable enforceable standards, but that a
minority of waters contains chemical or microbiological contaminants of
potential concern.
Recommendations
Every
American has a right to safe, good-tasting water from the tap. If we choose to
buy bottled water, we deserve assurances that it too is safe. In addition,
whether our water comes from a tap or a bottle, we have a right to know what's
in it. Among our key recommendations are:
• FDA should set strict limits (equivalent to those in California, EPA rules,
international standards, or industry guidelines, whichever is most health
protective) for contaminants of concern in bottled water, including arsenic,
heterotrophic-plate-count bacteria, E. coli and other parasites and pathogens,
Pseudomonas aeruginosa, and synthetic organic chemicals, including chemicals
such as phthalate, which can leach from plastic.
• FDA's rules
should be overhauled and should apply to all bottled water distributed
nationally or within a state, carbonated or not. To comply with common sense and
a new requirement tucked into the 1996 Safe Drinking Water Act Amendments, FDA
standards must be made at least as strict as those applicable to city tap water
supplies. The FDA should adopt rules for bottled water testing, to control
microbial and chemical contaminants, to protect water sources, to ensure the
reporting of test results and violations to state and federal officials, to
train and certify operators of water bottling plants, and to require the use of
certified labs. In addition, FDA should do its own audits and monitoring of the
quality of bottled water sold across the nation and should publicly release the
results.
• Right-to-know
requirements should require water-bottle labels to disclose contaminants, the
exact water source, treatment, and other key information, as is now required of
tap water systems. If bottled water is so pure, why not prove it with full
disclosure on the label?
• FDA's bottled
water program and state programs must be better funded, with a new
penny-per-bottle fee on bottled water to fund regulatory programs, testing, and
enforcement.
• State bottled
water programs should be subject to federal review and approval, and should
receive federal funding from the penny-per-bottle fee recommended above.
• If FDA fails
within 18 months to make its bottled water rules and its regulatory oversight
and enforcement at least as stringent as those for tap water, the bottled water
regulatory program and funding for it (including the proceeds from a
penny-per-bottle fee) should be transferred to EPA. We recommend this transfer
with some trepidation, in light of EPA's less-than-perfect tap water program and
its own serious resource constraints. We conclude, however, that it would be
hard for EPA authority to be worse than FDA's seriously deficient program, and
that a transfer of funding for bottled water supervision to EPA from FDA would
help. Clearly EPA has more resources dedicated to drinking water and has adopted
stricter rules and oversight of state programs than FDA has. More stringent EPA
tap water rules should be applied to bottled water within six months after
transfer of authority.
• A credible
independent third-party nongovernmental organization should establish a
"certified safe" bottled water program that is truly open, ensures full
compliance with all FDA, EPA, state, industry, and international standards and
guidelines, does twice-a-year surprise inspections, documents sufficient source
protection and treatment to meet EPA/Centers for Disease Control and Prevention
(CDC) criteria for Cryptosporidium-safe bottled water, and makes readily
available (including on the Web) all inspections and monitoring results.
Currently neither NSF nor International Bottled Water Association certifications
have sufficiently stringent criteria, nor are they sufficiently independent of
the industry, to provide consumer confidence that such strict standards are met.
Immune-compromised or other vulnerable people particularly may want such
certification to be fully confident of their bottled water's purity.
• While we
reasonably may choose to use bottled water for convenience, taste, or as a
temporary alternative to contaminated tap water, it is no long-term national
solution to this problem. Bottled water sometimes is contaminated, and we don't
use it to bathe, shower, etc. -- major routes of exposure for some tap water
contaminants. A major shift to bottled water could undermine funding for tap
water protection, raising serious equity issues for the poor. Manufacture and
shipping of billions of bottles causes unnecessary energy and petroleum
consumption, leads to landfilling or incineration of bottles, and can release
environmental toxins. The long-term solution to our water woes is to fix our tap
water so it is safe for everyone, and tastes and smells good.
