As I previously wrote I am in the middle of a complete remodel of a home. When I was stripping out all of the old plumbing I realized I took out all but a 4 foot section of the old plumbing that is still attached to the ground wire. Is it safe for me to re-attach this wire somewhere else without getting a shock? Should I shut the main breaker off to make it safer? Please help.

Shutting off breakers doesn't disconnect the ground, but it can't hurt to shut off the main breaker.
You didn't say what kind of plumbing you've installed. If it's plastic, there's no point in placing a ground on it.
Is there a grounding rod outside?

Yes, I have a grounding wire that is going outside. I am putting either PVC or copper plumbing back in.

Any copper plumbing you install should be bonded back to the bonded buss bar in the service or building disconnecting means. In order to serve as a grounding electrode for your home the clamp should be attached to an underground metal water pipe within five feet of were it enters your home. There must not be any plastic pipe or insulating fittings between the point of attachment and the underground piping. The best practice is to make the grounding connection on the supply side of the first control valve in the water line. Since no one is going to cut in to a pipe they can't shut off that prevents later plumbing work from leaving the home ungrounded.
