Distilled Doesnt Mean Pure

Distilled Doesn't Mean Pure Heres a comment a reader posted in response to my article on removing fluoride from water:Ive been taught that distilled water is the purest that one can drink. On the original article you write that this is not a safe assumption. How so?Distillation does purify water, but it cant remove all contaminants. Actually, distilled water can be very impure. Consider how distillation works. First, youre basically boiling water and then letting it cool to collect it again. Ideally contaminants with different boiling points will be removed, if you are careful to collect the distilled liquid at exactly the right temperature and pressure. Its not as easy as it sounds. Plus, there are contaminants that wont separate from the water just from vaporization. Sometimes the distilling process actually adds contaminants that werent originally present, from the glassware or metal components.For distilled drinking water, keep in mind even if the distillation process is scrupulous, impurities come from the container into which the water is placed. Heavy metals are used to stabilize packaging plastics and can leach into the water over time. For that matter, plastic monomers coat a new container and become a part of bottled water.Hard Soft Water | Distilling Ethanol for Your Car
