They put so much chlorine in the water when I was in Egypt it would burn your skin in the shower. We boiled water to drive off the chlorine so you could drink it.
Around here the water is so hard you best do a quick spin or get beat to death.
Yeah.... I have a natural artesian spring... No chlorine (unless something dead gets in it), no fluoride, no nothing. Hard water... but sweet... Gives me spots on my mason jars, but I can live with that.
Other than that, you don't leave it standing in the sink too long. If you don't tend to do dishes, it would be stinking in a day or two.
Dang good water. Living water. I attribute quite a bit of my recovery from illness to it.
