The Purest Water of Them All
Kelly Izlar in Scientific American:
“When you taste something, you’re comparing the taste of that water to the saliva in your mouth,” says Gary Burlingame, who supervises water quality for the Philadelphia Water Department. “The saliva in your mouth is salty.”
Salty saliva bathes your tongue, drenching every one of your thousands of taste buds. It protects you from nasty bacteria, moistens your food, helps you pronounce the word “stalactite” and even lets you know when you might be drinking something bad for you. Like water.
Pure water, that is.
Stripping water down to an ultrapure state makes it unfit for human consumption.
