[black][size 3]Hey Dave,[/size][/black]
[black][size 3][/size][/black]
[black][size 3]Wow 10 $ a gallon for H2O. Gas is cheaper in my area, so is milk, for that matter, so is booze.[/size][/black]
[black][size 3][/size][/black]
[black][size 3]I guess that means I should be frugal and drink more beer or Tequila.[/size][/black]
[black][size 3][/size][/black]
[black][size 3]One note, Typically bottled water in not distilled - it is filtered only. Distillation is a different process - that is where the water is converted to vapor then back to a pure liquid again without any particulate matter. All distilled water has to be legally and specifically labeled as "Distilled" because there are applications(medical and other) where it is imperative that the water be verified as 100 % pure - as only distillation can provide. The commercial filtering processes do not make water 100 % pure.[/size][/black]
[black][size 3][/size][/black]
[black][size 3]As far as chlorination goes, The amount of chlorine added by law is only enough to inhibit bacterial growth - not kill anything. If they add enough chlorine to kill everything, a person could not safely drink it for very long. Chlorinated water still contains some microbial life forms - but at a concentration level such that most people will not be adversely affected.[/size][/black]
[black][size 3][/size][/black]
[black][size 3]Another interesting note. The water you buy falls within the FDA's jurisdiction. The water from your tap is under the Department of Agriculture, EPA (safe drinking water act(SDWA)) and is locally enforced. The FDA has lower standards for purity in some areas and higher in others, but, the FDA, being a federal agency can accept the EPA standards or not. With that, it stands to reason that your tap water could be cleaner than just commercially filtered water. Not always the case though - quality asssurance seems to be a localized political issue and the FDA often accepts the EPA's guidlines. The crux of the matter here is the frequency of quality testing. Local tap water is constantly being tested locally. Bottled water only is mandated to be tested by the FDA on a yearly basis. [/size][/black]
[black][size 3][/size][/black]
[black][size 3]Make sense to you ? Well, not entirely to me, but I've known myself to be dumb in some things.[/size][/black]
[size 3][/size]
[size 3]Lastly, when you purchase water, carefully note the differences on the labels. The bottle will say something like the following:[/size]
[size 3]Drinking water, Filtered water, purified water, spring water, well water or distilled water - all of these designations have corresponding legal definitions and specific requirements to be labeled as such. [/size]
[size 3][/size]
[size 3]However, if you've ever tried to read those labels, you'll know that it really doesn't matter too much what the label says, because you've probably discovered that a person would need a Ph.D. in chemistry to understand some of that stuff. Me, I took lots of chemistry in school - but, I'm just a lowly Biologist that drinks water and likes to fish in it.[/size]
[size 3][/size]
[size 3]Sorry about the rambling - hopefully, I got all that stuff straight - it's been a while since I took that seminar from the Salt Lake Water District.[/size]
