16 facts that show why bottled water is one of the biggest scams of the century

Flickr/Vlad B.There's nothing quite like the feeling of pure, ice-cold hydration. Some of us get our water for free from the tap. The rest pay for it - at the cost of roughly $100 billion a year.

At that steep a price tag, you might assume buying the bottled stuff would be worth it. In most cases, you'd be wrong.

For the vast majority of Americans, a glass from the tap and a glass from the bottle are virtually identical as far as their health and nutritional quality are concerned. In some cases, publicly-sourced tap may actually be safer since it is usually tested more frequently.

But there are plenty of reasons to stop shelling out for bottled water. Read on to find out all the things you didn't know about your drinking water.
