Eternal life or no, drinking this water daily is bound to have some interesting results. Via National Geographic:
Thanks to the myth of Ponce de Leon’s trip, Florida—known for its large population of retirees—is now awash in “fountains of youth.” Only one, however, is known to be radioactive.
In Punta Gorda, a town on Charlotte Harbor, a blocky, green-tiled fountain abuts an empty lot near the harbor. A spigot juts out near the top to release water from the artesian well below.
On the side facing away from the street, a public health notice warns that the water “exceeds the maximum contaminant level for radioactivity.” The water from the well is also heavy in sulfates, which give it a smell of rotten eggs. This hasn’t stopped the locals from drinking from it regularly. “I drank out of that well every day,” said Gussie Baker, a resident of Punta Gorda for all of her 78 years.
