What's the difference, isn't water, water?

What's the difference? Isn't water, water? 

Water is water the way food is food, the way wine is wine, the way cheese is cheese, and the way air is air! Hormel Corned Beef Hash and Prime Rib are NOT the same. Velveeta Cheese Spread and Stilton are NOT the same. Dom Perignon and Korbel are NOT the same. Fresh ocean breezes and inner city smog are NOT the same. 

Virgin waters drawn from deep inside the earth, containing unique healthy chemistries, bottled untouched by human hands, are NOT the same as municipal well water, or surface waters collected in a reservoir, or the bottled tap waters scrubbed chemically then sold in mass marketing outlets.
