is a colorless, volatile substance with a fruity smell. Although it forms naturally in some fruit, it can cause an off-taste in bottled water. Acetaldehyde forms by degradation of PET through the mishandling of the material. High temperatures (PET decomposes above 300 °C or 570 °F), high pressures, extruder speeds (excessive shear flow raises temperature), and long barrel residence times all contribute to the production of acetaldehyde. When acetaldehyde is produced, some of it remains dissolved in the walls of a container and then into the product stored inside, altering the taste and aroma. This is not such a problem for non-consumables (such as shampoo), for fruit juices (which already contain acetaldehyde), or for strong-tasting drinks like soft drinks. For bottled water, however, low acetaldehyde content is quite important, because, if nothing masks the aroma, even extremely low concentrations (10–20 parts per billion in the water) of acetaldehyde can produce an off-taste.

Plastic drinking bottles contain many chemicals, some of which interfere with hormones in the body. These chemicals include bisphenol-A, or BPA, and phthalates, among others. Chemicals in the plastic can leach into bottled water, especially when exposed to heat or when the bottle is old. Different types of plastic---indicated by the number inside the triangle of arrows on the bottom of the bottle---contain different chemicals. Bottlers generally use the type of plastic labeled "1," and identified by the letters PET or PETE. Advocacy groups including the Natural Resources Defense Council and Sierra Club have pointed out evidence of harmful chemicals leaching into food or water and have called for further research to ensure safety.

When you hear of efforts to reduce dependence on fossil fuels, you may envision driving your car as the primary way you use petroleum. But every time you buy a plastic drinking bottle, you are also using some of the world's limited supply of oil--manufacturers use petroleum to make and transport plastic products. Plastic bottle production in the U.S. requires millions of barrels of crude oil annually. Beverage companies then use fuel to transport the bottles all over the world, polluting the atmosphere in the process. The next time you drink a bottle of water, take a look at the label to see where it came from and how far it traveled. Bottled water frequently travels thousands of miles to people who already have clean tap water readily available.
