It's all metal.  Metal comes in, metal throughout the home.

The electrical panel has a grounding wire that hooks to the metal copper. There is high V/M with ED88T on this wire, and high M.  So the electrical panel is grounding into the copper water pipe, and plenty of current is flowing,.. the pipe has turned greenish and the grounding connector has oxidized and rusted, .. I put a new one.  But obviously, plenty of current is flowing down into the earth through this copper pipe.

It is not flowing up towards my house though, the pipes upstairs do not have magnetic fields, so I don't know if I should be worried about it.
I have a water softener with water pipes that stops the current(like you say), but, I also put a jumper wire across, and with jumper/without, still no M fields upstairs.
I have gas pipes as well which are connected to the water lines, to ground them.  If I don't have a jumper across the softener, then I'm not sure if it's ok to have the gas lines not grounded to the same place as the electrical panel..  
Also, I have a furnace that I think is grounded to the electrical ground inside it, and the furnace ductwork touches the water pipes... So I think no matter what I do, things will always be touching the electrical ground.. But my shielding can at least be away from it.

I am mostly looking for what to do with my shielding foil.. if I leave it un grounded, I get high V/M, is it ok to leave it like that then if connecting to ground makes it worse?..

Maybe there's something else that absorbs electrons other than ground that I could use =)?
