A mineral that is "____ chloride" doesn't mean chlorine lol It means the mineral was negatively charged. For example, calcium chloride is just hydrochloric acid with calcium hydroxide. People think the word means chlorine when it don't. There is chlorine in tap water as a cleanser. Cheaper bottled waters will use it as well but this never has to be listed on the label.
I drink spring water. Have done so for the last 10 years. I am good on these gimmick waters.
