Often, local administrations will just shut down local springs, rather than to risk some meathead trying to sue them.
I know of several which were available through the years. One near Kane, PA..another very prominent on RT 19 at Belfast, NY ..and many others, all shut down, likely for the same reason.
I suspect that there once were many of them in the horse & buggy days. Back then, watering troughs were as needed as gas pumps are today. In those days in this area, once dotted with small dairy farms of 20-30 cows, farmers often piped springs from well back in the fields..to the roadside, where their milk cans were kept cool with fresh spring water in concrete troughs, awaiting pickup.
Naturally, anyone travelling by horse was allowed to drink at them. I can remember some of these troughs.
