When you visit the well park, there are informational signs everywhere about the Artesian Well. If memory serves, when they were drilling for natural gas, the tapped instead to this underground river, and the water pressure drove it up the pipe; been running ever since. It's delicious spring water. I've actually tested it for things myself. It's a bit on the alkaline side of PH. Runners buy water with this type of alkalinity because it's good for their heart and blood circulation. Interesting stories. I met one gentleman who has beem coming from Indy for 35 years, weekly to get water. He heard from another visitor who said they traced the underground river to begin somewhere in Virginia.
