stated position on regulating water facilities is as follows: "Because FDA's experience over the years has shown that bottled water has a good safety record, bottled water plants generally are assigned low priority for inspection." The bottled water industry has turned to regulating itself in order to prove the safety of their products to the public. Certifications by the National Sanitation Foundation (NSF) and the International Bottled Water Association (IBWA) give consumers confidence that someone is assessing the quality of their drinking water. There are several different types of bottled waters available: *Distilled Water is created by boiling water and condensing the steam in a clean container. Impurities, contaminants, and minerals are left behind. Distilled water contains virtually 0 parts per million (ppm) of total dissolved solids (TDS). Total Dissolved Solids includes bad solids, like mercury and bacteria, as well as good solids, like calcium and magnesium. *Reverse Osmosis is a purification technique in which water is forced through semipermeable membranes not porous enough to let minerals or other contaminants through. Dasani™ is a bottled water purified by reverse osmosis (minerals are added back into the water after purification to enhance taste leading to 15 ppm TDS). *Spring Water is water from an underground source that flows to the earth's surface unaided. Collected at the source, spring water is brought to a bottling plant and tested for impurities and contaminants similar to tap water. Poland Spring® is bottled spring water. It averages between 26 and 60 ppm TDS. *Mineral Water originates from an underground water source and contains a constant level of minerals and trace elements, no minerals may be added later. It has no less than 250 ppm TDS. Calistoga® Sparkling Mineral Water contains between 490 and 590 ppm TDS. Perrier® averages around 475 ppm TDS.

Problems with Bottled Water: 1. Phthalates are chemicals used in making plastics. Most of the disposable water bottles today are polyethylene terephthalate, or PET, bottles. Phthalatesare used in thousands of consumer products from plastic bags to passifiers to shampoos and makeup, and have been shown to leach into the environment and into our bodies. In high enough concentrations phthalates can be carcinogenic, interfere with the endocrine system, and cause damage to reproductive organs and developing fetuses. What's a high enough concentration? Nobody knows yet. There are several different types of phthalates in use and because they are used in such a wide variety of products everyone's exposure will vary. Our thoughts? Error on the side of caution. Especially if you are pregnant, intend to get pregnant, or have a personal orfamily history of endocrine related cancers (breast, prostate, ovarian, etc). 2. Think about the environmental burden of all these bottles! It can take upwards of 100 years for a plastic bottle to break down. And when it does finally break down think about the chemicals that leach into the environment and lead to hormonal problems for frogs, fish, birds, and once again… you! The earth's water cycle is a closed system, what we have is what we get! 3. Bottled water is not a cost effective way to get your daily serving. If you drink 64oz of water a day (and we recommend that you drink half your body weight in ounces daily) you could spend anywhere from $400 to $800 dollars a year just on water!!! Problems with Tap Water: 1. Municipal water companies have to test for
approximately 120 contaminants in their water on an ongoing basis.
In a 5 year survey of more than 22 million tap water samples, the
environmental watchdog organization Environmental Working Group (ewg.org)
found 260 contaminants present in the nation's tap water, 140 of
which are not regulated by the EPA and have no safety standards.
According to chemical listings in seven standard government and industry
toxicity references 52 of these contaminants are linked to cancer,
41 to reproductive toxicity, 36 to developmental toxicity, and 16
to immune system damage. 2. There are more than 82,000 chemicals in use in the U.S. today. When it comes to water contamination we will only find what we are looking for. Between 1999 and 2000 a US Geological Survey found hormones, cholesterol, antibiotics, and other pharmaceuticals in 111 streams around the country. 3. DBP's, disinfectant by-products. Many municipal water sources use ozone and/or chloramines (chlorine and ammonia) to kill bacteria, parasites, and other microbes. Both of these techniques create by-products that have been shown to cause cancer in laboratory animals. Purifying water is a tricky balancing act in which the risk of pathogenic microbes must be weighed against the risk of toxic by-products. To date several hundred DBP's have been identified.

| what to do... | ||||||||
our recommendations 1. Visit the Environmental
Working Group's database of water samples. Enter your zip code, select your water company,
and find out the top contaminants of concern in your water supply. 2. Purchase a water filter that is certified by the NSF (an independent public health and consumer safety testing organization) that will remove a wide range of contaminants, including those of particular concern for your area. We recommend looking at a Multi-Pure filtration unit. We use a Multi-Pure filter at home and in the office. The company has the most extensive list of filtered contaminants on the market. While the upfront cost for a filtration unit can be a little steep (from $180 to $500) the filters ($50) only have to be changed once a year. In the long run this is an enormous savings over other purified water options. Barry Levine is a recommended local Multi-Pure distributor and can be reached at 617.617.738.9597 for orders. 3. Reserve the use of plastic bottles for traveling and for times when a glass just won't cut it. Drink the majority of your water from a non-plastic container. 4. Never heat water in a plastic container or drink from a water bottle that's been sitting in the sun for long periods of time.
