Choosing tap water over bottled water is quickly catching on, especially for those who are health-conscious.  In most of North America, tap water is tested to ensure that it’s free of bacteria.  On the other hand, there are no regulations that oversee the testing of bottled water. 

Secondly, the plastic in bottles will decompose (with UV exposure) and leech into the water with time.  In 2001, a study at the University of Idaho reported that carcinogenic levels of a chemical known as DEHA may leech from polyethylene terephthalate (PET) bottles when they are reused or heated.  For me, this is a major concern. 

I just got my first Kleen Kanteen water bottle, and I love it.  I can fill it at home and at work, and the stainless steel keeps the water colder than plastic can.  With this purchase, I’m helping the environment, and my own health, at the same time!
