Plastic bottles are not sustainable, no matter what we've been told. Using vast quantities of fossil fuels and water, these bottles are manufactured, filled, and shipped around the globe. (Not a good carbon footprint!) Neither are bottles biodegradable in any meaningful way: what you drink in a few minutes can stick around for a thousand years. Even with recycling efforts, 6 out of 7 plastic bottles consumed in the U.S. are "downcycled"—sent somewhere out of sight and out of mind where, for the next millennia, toxins from degrading plastic containers can leach into watersheds and soil. That's just not something we need to give to global neighbors and future generations. Most bottled water is glorified tap water at 10,000 times the cost. The label on your bottled water may depict a peaceful mountain stream, but that doesn't mean the water inside is pure and pristine. Only some bottled water comes from springs or groundwater sources. It turns out that approximately 25% of bottled water is sourced from ... the tap. Sure, some companies filter or radiate the tap water with ultraviolet light before selling it to you at several thousand times the cost of municipal tap water. (Examples include Aquafina, Dasani, and many other brands.)
Moreover, studies show that bottled water samples can contain phthalates, mold, microbes, benzene, trihalomethanes, even arsenic. And only recently did the FDA start regulating bottled water for E. Coli, thanks to advocacy by the Natural Resources Defense Council. Upshot: bottled water markup is extreme. Health standards are often a wash and may even favor tap water.

Many bottled waters contain toxins, even if they've nixed BPA. Plastic isn't just bad for the planet, It's not good for you, either. Bottled water companies increasingly use BPA-free plastic, but laced into plastic bottles are other chemicals that can seep out if bottles are exposed to heat or sit around for a long time. Some of these chemicals are possible endocrine disruptors. No one knows for sure what the health outcomes are. Do you really want your body to undergo that experiment? . 325
122 I used a negative logarithm of the hydrogen concentration to create a scale from 0-14, where a pH of less than 7 is an acid, 7 is neutral, and higher than 7 is an alkali," reads an 2009 announcement from Carlsberg, on the 100th anniversary of the breakthrough. So water has a pH of 7, lemon juice 2.4, and bleach 12.5. The pH of beer is between 4.1. and 4.6 .... Before the pH scale, the only parameter to measure acid levels were vague terms such as 'good,' 'bad,' or 'slightly more than last time.' The innumerable useful applications of the pH (short for "potential of Hydrogen") scale range from foods and beverages to cosmetics, pharmaceuticals, and medical diagnostics. Just about every liquid has had its pH measured at some time—including those in our bodies—which, it is very important to note, have more than one pH level. Take the stomach, for instance. It has a pH ranging from 1.35 to 3.5, due to production of hydrocloric acid, which aids in digestion. Blood, on the other hand, must always be slightly alkaline, with a pH of 7.35 to 7.45. The body's buffering systems keep it within that precise range, and excess acid is excreted by the lungs and kidneys. That's part of their job, and they are very, very good at it. The body maintains its pH balance over widely differing diets, and even though what you eat can affect the pH level of your urine, it cannot affect the pH level of your blood. Understand? Good. Now back to
. These electrical devices—which generally cost from $1,000 to almost $6,000 and are often sold by multi-level marketing companies—attach to the kitchen faucet or go under the sink. They strip out contaminants, like other filters, and, besides producing alkaline water for drinking, they also produce acidic water, for cleaning. If you've ever washed windows with a water-and-vinegar mixture, you know acidic water is a good cleansing agent. But the notion that alkaline water can fight or prevent disease? Any chemist will tell you that there is still much to learn about water, but hmmm. Many of the online claims are based on the theory that ionized alkaline water has smaller "clusters" of molecules. According to the Kangen Water website, for instance, "These small clusters make alkaline water Kangen Water more soluble and permeable, allowing you to absorb the important vitamins and nutrients your body needs." And The Alkalizer ("A Wetter Water for a Better Body") maintains that, "The smaller mineral clusters, as measured by the use of a Nuclear Magnetic Resonance device is a more hydrating water than normal tap water. Through electrolysis large tap mineral clusters are reduced from their original size. The smaller cluster size gives the water excellent hydrating properties, high solubility and good permeability."
