I didn't either... Fun fact is that The United States has not set any limits on safe levels of over 160 water contaminants. Most of the population's drinking water is loaded with highly toxic chemicals like: chromium( think Erin Brockovich), nitrate, and excessive amounts of chlorine and fluoride. We bathe in water and absorb it through our skin. Imagine how much we can take off  of our bodies plate if we were intentional with our water sourcing?
