Have you ever wondered, "Just, how clean is this water I'm drinking?" People, these days worry about what is in their water but end up not doing anything about it. Usually they extange their water systems or get bottled water. Still, you can not just go by the quality of the water that the ad tells you. People can contract very harmful diseases from drinking from their water systems or strems or lakes. Sometimes we think, "If I can't see it it's not there" which is completely not true. Taking precautions in what water you drink could lessen the risk of getting yourself sick.

I became interested in this experiment when I was looking through a catalog for experiments. I knew I wanted to have something to do with water. I found a kit that tested five different things in the water. So I thought about it and I talked to my teacher and my mom and they helped finalize my idea. So I decided to test the water dispensed from the water machines that are outside of the supermarket. I went around to supermarkets and collected the water. I, then, tested that water against distilled water from the Everpure H200 system. The main reason why I wanted to do this was to see which drinking water is best for me and my family.
