As you know I live on a hill of red clay. I might as well live on top of a high voltage insulator. Two copper ground rods spaced one foot apart ( installed ten years ago), now show an infinite impedance between the two. I just drove a new 8ft galvanized ground rod 5 feet from the copper ones and not surprisingly, I created a battery between one of the copper rods and the galvanized, I get 0.6 volts DC. It ticks me off that I cant get a decent ground, I don't know what to do. I'm tempted to pour rock salt around the rods but I think that would just corrode the metal or oxidize the copper. It appeared that the copper rods had oxidized and after I pulled it up 6 inches with a farm jack, I got better continuity. The soil was wet from rain when I made these tests. There is a high content of iron in my well water and iron in the gravel of my driveway (you'd think that would help). I think the only real ground I have is the 20 feet of 6" iron pipe in the top of my well. Any suggestions?
