It's just hard for me to believe our tap water is measuring the same numbers as bottled spring water.
If you're from this area, you don't realize just how bad our tap water tastes. I'm from the Memphis area, and the water is so soft and tastes like any bottled water you can buy.
When I first moved here, I remember how adding ice to my tea ruined the taste of the tea. I'm used to it now and can't taste the difference as much.
