Toxic Plastic Water Bottles
by Debra Lynn Dadd
I recently received a question from one of my readers about the safety
of drinking water from clear plastic water bottles. These bottles, made
from Lexan polycarbonate resin (a plastic polymer), are widely used for
single-serving sales to one-gallon of water in stores and home-delivery
bottles.
These bottles appear to be safe because
they do not impart any taste or odor to the water. Lexan polycarbonate
is also used to make compact discs and DVDs, bulletproof windows,
mobile phones, and computers.
The water delivery company sent my reader
a notice saying that their Lexan polycarbonate bottles are perfectly
safe to use. They suggested their customers visit a website that was
designed to portray this plastic in a positive light.
But, actually, a toxic chemical is
lurking in these bottles that does end up in the water you drink. Lexan
used to be used to make baby bottles, but these are no longer sold.
Hmmmmm...
Stay Away From BPA
In 1998, Dr. Patricia Hunt of Case
Western University in Ohio discovered that one of the components of
Lexan polycarbonate resin--bisphenol-A (BPA)--can leach into water from
water bottles. BPA is a potent hormone disruptor. It can impair the
reproductive organs and have adverse effects on breast tissue and
prostate development.
Who do we believe? The water delivery company or Dr. Hunt?
I'm inclined to go with Dr. Hunt. I went to a website maintained by the authors of
Our Stolen Future: How We Are Threatening Our Fertility, Intelligence and Survival,
who are continuously searching the scientific literature for
information on endochrine disruptors. The Our Stolen Future page on
bisphenol-a (http://www.ourstolenfuture.org/NewScience/oncompounds/bisphenola/bpauses.htm#recentimportant)
gives a whole page of links to scientific studies that show that BPA damages the endocrine system in a variety of ways.
BPA can leach from water bottles when
exposured to heat and cleaning agents, but detectable levels of BPA can
also leach into water from bottles just sitting at room temperature,
according to a 2003 study conducted by the University of Missouri
published in the journal Environmental Health Perspectives.
Better Safe Than Sorry
Is there is a level of BPA that may be
acceptable? To answer that question we have to ask: acceptable to who?
A healthy male? A woman? A child? The elderly? And how would you know
how much leaching has occurred in the water? It could easily vary from
day to day depending on how long the water had been in the bottle,
whether or not the sun was shining on the bottle in the delivery truck,
and a variety of other factors.
I'm concerned enough about the possible danger of BPA that I am no longer purchasing bottled water in plastic bottles.
Health concerns aside, plastic is also
not good for the environment. Americans use about 10 million tons of
plastic every year, but recycle only about two percent of it. A plastic
milk jug takes about one million years to biodegrade. And, getting back
to health concerns, the manufacture of plastics produces toxic wastes
that return to us indirectly through polluted air, water, and soil.
But we also have to use common sense and
choose the greatest benefit at any given time. If your choice was to
drink spring water in the polycarbonate bottle or drink tap water or
drink no water at all on a hot summer day, I would say drink the purer
spring water in the polycarbonate bottle. Once in a while, a single
exposure will not do much harm. But you don't want to be using water
contained in a Lexan polycarbonate resin bottle as your everyday source
of water supply, or drink from these bottles all day long, every day.
There are other options.
Better Options
My best recommendation is to get a good
water filter that is right for your water and filter your water at
home. That way there is no questionable leaching at all. Even though
this may be expensive, it is one of the best investments you can make
in your health and will save thousands of dollars in medical expenses
in the long run.
For those of you who carry or purchase
water in the small, single-serving polycarbonate bottles, you can
purchase plastic-free refillable bottles in various sizes to suit your
needs. They are lightweight and much more attractive than the
disposable plastic bottles.
It's a good idea, particularly in the
summertime, to carry clean water with you, as your body needs water
throughout the day for good health. The Mayo Clinic suggests you divide
your weight in half and drink that many ounces of water every day. So
if you weigh 128 pounds, that would be 64 ounces or 8 8-ounce glasses
of water per day. It's better to carry your own clean water in a safe
container than drink tap water or water in a plastic bottle.

Luckily we bpa-free options online now.... like www.newbornfree.com for plastic baby bottles or
www.titanwaterbottle.com for bpa-free water bottles (for adults).
There are some other great alternatives if you look around online.
Why continue using products containing bishpenol a if we don't have to?
I'm still looking for a good place to buy bpa-free storage containers for food. Please post if you know of one!

Interesting article - the BPA issue has been in the news in the UK just recently so I'll be keeping watch on any further articles.
