Water has always been a fascination of mine.  It's one of the most important things you can put in your body, yet people seem to neglect it.  Think about it, you drink up to 8 cups of it everyday!  You body is made up of 55% to 78% water.  I've lived in the Chicago area all my life and this site will help you determine whether or not you want to continue drinking Chicago water supply.  Recent studies have shown levels of chromium, pharmaceutical drugs, and other disruptive and cancer causing substances in our water supply.  I highly recommend a Premier reverse osmosis water purification system and I'll explain why.
