It depends on the spring water or the well water. Many great springs around here (NW Arkansas) have been closed off due to coliform bacteria in the water. Wells that have not been used for years, and far away from other farms also have the same. Very deep wells here have a strong “metalic” taste and the water stinks. Some have Sulfur so bad it is unusable. I have three wells on my property and no longer use any of them. When the city ran rural water out this way we went right on it. When the power is out during ice and snow storms we still have running water.
When living out West, alkali was in most of the wells. Some had so much in them they were used only to wash dishes, wash clothes, and flush toilets, IF you had a toilet. Drinking the well water in the West did give us natural fluoride and made our teeth super strong.
I am 71 and have all my teeth. Same for my wife from Dallas.
You can probably thank tyson farms for that.
