Platted Utility Easements! Help appreciated!
Why don't you call for utility locates on the easement and find out if there's anything buried through it. If it's not been used by any of your utilities it would likely be a simple matter of vacating the easement through a platting action. If nobody is using it they're not likely to object if there's an equal practical alternative. If locates reveal buried gas, power, fiber optics, you can cut your losses early as relocating them will get into big money.
Just because I'm paranoid doesn't mean they're not out to get me.
The easement has been there since 1956; the nursery has been in place since at least 1995 and there has never been a problem. why is it an issue today?

You have learned that there is (or was) a water line in that easement. The thing about water is that sanitary and untreated storm water lines can't be within a certain distance of it (at least not without some rather expensive precautions). Technically that distance can be a vertical seperation but in practice that means the only utility you are going to find in close proximity to water is natural gas.
