Water is one of the fastest growing industries in the world today. NRDC's study included testing of more than 1,000 bottles of 103 brands of bottled water. While most of the tested waters were found to be of high quality, some brands were contaminated: about one-third of the waters tested contained levels of contamination -- including synthetic organic chemicals, bacteria, and arsenic -- in at least one sample that exceeded allowable limits under either state or bottled water industry standards or guidelines.

We could go on and on about the current water situation in the world but we think you're beginning to get the picture. All of the water on this planet has been recycled thousands upon thousands of time. Each time it picks up more contaminates. In the not to distant future, the filtration of water will fall more on you then the cities and states responsibilities.
