The panel is grounded to the cold water supply which runs 15' to the basement wall and then 6' deep all the way out to the street (70'). The water meter is metal (bronze) and there is no plastic anywhere in the system. My shack ground is an 5/8" x 8' copper clad rod connected to 2" copper ribbon which runs from the other end of the house, enters the basement where the electrical service does (boy I love buried service) and is clamped under the same wire clamp used for the electrical panel. The only ground rod in the system is the one next to my shack window. 70' of metal water pipe is a pretty good ground. -- R.
