Welcome pilot.
First off there is usually porous soil where water comes to the surface or it wouldn't be able to leak out of the aquifer. It's always a gamble to start a pond in such an area but lots of ponds have been successfully built around springs. Personally I would prefer to build the pond in such a way that the spring would be above or just at full pool level of the proposed pond if the lay of the land allows.
The only way I know to tell for sure is to start moving dirt. You need to ask some questions before starting though & the fact you're looking for knowledge here has just greatly increased the chance you'll end up with something that will give alot of pleasure for years to come.
Think about what your initial goals for a pond will be & list them here & the guys like Rainman can offer lots of good advice. How big .. will it be primarily for fishing .. or aesthetics.. swimming .. for kids .. etc.
