Those Alpine sediments are near end of life after thousands of years. Kidding aside, my well water is a good reason to get bottled water. Otherwise it’s nuts. Bottled water was up to $2.49 per gallon. I remember when gasoline was cheaper. In Chicago they put an extra tax on bottled water.
In my case, my well water is super soft and comes from the same place as Nestle Waters in Hawkins, Texas!
When I lived in Oklahoma (North of OKC), our well water was pretty hard and later municipal water was really hard too. The oil boom also killed some rural farmstead wells with salt water. Our personal windmills were all tied to a water well FWIW.
