“Much is being made of the benefits of natural water, but all water needs
to be processed so that we can drink it.” —Kevin Prior, water and
wastewater chemical scientist
I was watching 60 Minutes last night, and Andy Rooney came on and
discussed different types of bottled water. He pointed out that there were
hundreds of different types of bottled water on the market. Rooney’s questions
were, was bottled water safer than tap water, and was there a difference in
expensive bottled water versus cheap bottled water? He also spoke to a
researcher whose specialty was investigating water purity and content. The
researcher told Rooney that there was very little difference in the contents of
bottled waters he had tested. He told Rooney that he personally drinks tap
water.
What’s funny is that we make lemonade, Kool-Aid, and coffee with tap water,
but we’re afraid to drink plain tap water (at least some of us who insist on
consuming bottled water). We are obsessed with drinking all natural water.
However, when we find water during our outdoor excursions, we run the water
through a man-made purifier or treat it with purifying tablets. When finding
water in the wilderness, we’re generally advised to purify water even if it
appears crystal clear. Why do this? Why not take advantage of all natural water?
Because all natural water may contain harmful microbes.
A study conducted by
Lalumandier and Ayers (2) looked at the fluoride level and bacterial content
of commercially bottled waters versus municipal tap water. Fifty-seven samples
of five categories of bottled water were purchased from local stores. Samples of
tap water were collected in sterile containers from the four local water
processing plants. Fluoride levels were determined, and water was cultured
quantitatively. Levels of bacteria were calculated as colony forming units (CFU)
per milliliter.
Fluoride levels within the range recommended for drinking water by the Ohio
Environmental Protection Agency, Cincinnati, Ohio—0.80 to 1.30 mg/L—were found
in only three samples of bottled water tested. The fluoride levels of tap water
samples were within 0.04 mg/L of the optimal fluoride level of 1.00 mg/L. The
bacterial counts in the bottled water samples ranged from less than 0.01 CFU/mL
to 4900 CFU/mL. In contrast, bacterial counts in samples of tap water ranged
from 0.2 to 2.7 CFU/mL. Five percent of the bottled water purchased in Cleveland
fell within the required fluoride range recommended by the state compared with
100 percent of the tap water samples, all of which were also within 0.04 mg/L of
the optimal fluoride level of 1.00 mg/L. The researchers concluded that drinking
bottled water based on the assumption of purity could be misleading.
Americans really love their bottled water "water" , spending
approximately 6.5 to 7 billion dollars a year on it. Prices of bottled water
range from 75 cents to $6.00 per gallon. The price of tap water generally runs
between 80 cents and $6.40 per 1000 gallons.
The Natural Resources Defense Council (NRDC) published the results of a
four-year study in which they tested more than 1000 samples of 103 brands of
bottled water. The study indicated that approximately 25 percent or more of
bottled water is really just tap water. The NRDC also found that 18 of the 103
brands tested had more bacteria than allowed under microbiological purity
guidelines. About one fifth of the waters contained synthetic organic chemicals,
but these were generally at levels below state and federal standards.
Bottled water is subject to less rigorous purity standards and less frequent
tests for bacteria and chemical contaminants than those required for tap water.
Bottled water plants test for coliform bacteria once a week, and city tap water
is tested 100 or more times a month. (These are supposed standards. I’m not sure
if we can always rely on this actually occurring.)
According to one source, “Unsafe drinking water is the world’s number one
killer according to the UN. There are 250 million cases a year of water borne
diseases and 5 to 10 million deaths a year from water borne diseases arising
from untreated water. Simple filtration and disinfection with chlorine solution
(household bleach) can prevent most of these diseases being passed on through
drinking water” (3).
In addition, “There is also no convincing evidence of beneficial effects from
consuming high or low mineral content bottled waters” (WHO, No.256, October
2000) The biggest advantage of bottled water is the bottle itself. It makes
drinking water more convenient and is easier to carry than a water fountain.
