I know what true spring water is! The real thing is so wonderful. It ran down out of a pipe from the mountain. We only went to fill jugs on a farm since the water had the smell of rotten eggs. Sulfur in that water is what made it so, but it was enough to get us to drive to the mountain and fill so many jugs.
Today, I wonder if the same spring is healthy...contaminants may have made it undrinkable without getting ill.
If a person drinks certain contaminates, they can become very ill and not know it. There could be many types of worm eggs in the water which find their way into a human organ or digestive track or worse. "River blindness" is actually from ingesting the larvae and those larvae of the worm find host in a humans eye, causing blindness. The host's eyes turn a whitish color from the worms growing (mostly found in Africa) I don't recall the species, but water must be considered as well as food
What is in the bottled water cant be spring water. It must be treated water filtered or distilled.
Distilling water isn't difficult...just boil and catch the steam, and yes, that doesn't have the chlorine and other microbes. I do it for fish in tanks..but even they need the right kind of microbes to survive. I actually add them after the distillation process
For me, filtering some of the chlorine out for drinking is the best. Some cities have a really high content of chlorine and it is awful to taste, so for me it is just as good to filter and fill and go! Drinking "real"water is the best! And when that isn't the "best" why pay for water sold in a bottle?
most of the companies that distribute these water product I feel are just using a ploy as you said earlier. They prey on fear of bad water. Fear is a great motivator and will always sell the "good water" for "health" which can be achieved in much less expensive ways
