What to consider before building a pool

Hi there,
We are planning to build a swimming pool in our home. But we have heard that occasionally, a mild ground current has been experienced in some Dare and Currituck Counties pools. This appears to be the result of the Earth’s own natural electrical current rather than a pool defect or household current. Locations of certain properties may be affected more than others and the currents tend to be intermittent.

And I’m not particularly worried that we’re all going to die horribly in an electrified swimming pool. But really? Can “the Earth’s own natural electrical current” really fry your pool and take out your pacemaker? Is this something specific to the Outer Banks?
What do you guys think? Please share your opinions.
