-----Stopping copper pipe corrosion with zinc anodes
Can I use a zinc sacrificial anode to inhibit the corrosion of underground copper cold water piping ? If so where do I locate the anodes ?

It may not be at all practical, but from a theoretical standpoint it will certainly work. The anodes need to be in ground at least as wet as the ground the copper is in, and close enough to it that current can flow through the wet ground.
