You will need a PVC to NPT (National Pipe Thread) adapter. They come in male and female configurations.

Depends on what is leaking and why.

If the leak is at a threaded joint, and IF you can get the bad part off without damaging the rest of the joint you'll likely need to "chase" the threads to clear rust and debris out. They don't have to be spotless and perfect, but you do have to have enough thread for the PVC to latch onto. I usually bend a nail 90* and hold it with pliers to do the work. You can rent pipe dies and taps, if absolutely necessary.

If the pipe is beyond salvage, it will need to be replaced, which is likely a professionals job rather than a DIY'r project unless your skills are pretty good.
