Jeanie I don't want to scare you or anything, but bottled water isn't always better. You have to watch what type of plastic it is sitting in too.

Dasani was recalled and kicked out of the UK a few years ago because it had higher than normal levels of bromate in it. Hehe remember bromate directly effects thyroid function. It's known to increase cancer risk too.

Most of these bottled waters are simply tap water that has been put through a light filtration to get chlorine out. Nothing more than a Brita. Some do say reverse osmosis, so I give them some credit for that.

The other terrible things in water will still be in there including possibly fluoride. Most water facilities in the US are now testing positive for birth control pills, painkillers, anti-convulsants and psychotropic drugs. They say it's safe because of how little is in there....right. They say mercury is safe. lol

I'm not a crazy tree hugger, but bottled watered has substantially increased waste. Plastic bottles basically never break down and some bottle types may not be recyclable.

People who buy their water from a machine in the store need to make sure that the store is actually CHANGING the filter elements on time. Often times you think the water is clean and pure (which it would have been) but stuff is falling through because the filter is old and needs replaced. Who knows what type of bacteria could be growing inside the machine. Never ever ever ever buy a slushie drink at a restaurant...My in-laws are in the refrigeration business. Drink machines are NEVER cleaned. There is mold in those things. Same with ice machines at restaurants. Don't get ice.

If I had unlimited money, the first thing I'd do is buy every single type of bottled water and have it analyzed for everything. Then I'd go to every water company, ice making company and analyze their water. I'd put water in different types of plastic, shake them around, put them in normal "hot" temperatures, then test them again. I'd make a website with all this information for people to see. hehe That would probably cost me quite a bit of money. Maybe if I become famous I can do that. Once all the water data was complete, then I'd start on food.
