My wife's family maintains a summer home in North Carolina. One of the features of the neighborhood is that it boasts a natural spring that has a certain lithium content. Supposedly good for one's mental health. Judging from some of her relatives, you couldn't tell it.
Out here, the city gets its water from the McKenzie, an uncontrolled river fed by snow melt from the mountains. Almost nothing done to it and, there is at least one outfit in town bottling it.
Me, I git muh water outa uh hole in da ground... Supposedly has some manganese content, which is supposed to be good for my hair. On the other hand, my neighbors have arsenic in their water. It does nothing for my sanity, however.
