If they are drinking pure water from the well or spring, provided it was taken in pristine environment, it should be better then regular "clean" water. That is what concept of "mineral water" is, you get water directly from the ground, usually with some health benefits. Sometimes you get 'mineral water' packaged from retailer, but if you go to place where it originates, you can get it from the well. Microelements you get in that water is something you will not ever get in regular water and it is good for your body and brains, within reason. Drinking it exclusively will not be good for your kidneys I guess, but it is not intended for that. I wish reportes would not hype this as much and explain if there is genuine issue in how this water is getting collected, there might be genuine issues, but it is hard to understand where the problem is and this is not the first article I read.
