Next to air, the water is the most essential element to our survival.
Water is everywhere, but clean drinking water can no longer be granted to us.
Safe drinking water is harder to find in industrially developed countries than third world countries.
All sources of our drinking water, including municipal water systems, rivers, lakes, wells, contain some level of contamination.
Many contaminants are at low levels not enough not to cause immediate sicknesses, but it is proven that some will over time cause severe illnesses.
There is debate about bottled water too.
Bottled water's popularity is fueled in part by suspicions over the quality of top water.
Although often advertising themselves as superior to top water, bottlers are required in most cases only to meet the same quality standards as tap water.
So far, there is no way of knowing whether bottled water is better or worse.
That's why to be sure - protect yourself with a high quality water filter.
I believe it is important to drink water that has not been fluoridated and suggest you either oxygenate the water you drink or alkalize it.
Your own research will help you decide what is best for your situation.
