Canadian Service Panel Grounding - Part II

Existing Conditions: I have 2 grounding electrodes attached to the

100 amp service panel at my cottage in Canada. The first, a metal water pipe grounding electrode, has been eliminated due to the installation of our own water pump (not a well) using plastic pipe; it cannot be re-established. The second is a metal grounding rod of unknown length, driven into the earth at a shallow angle (20-30 degrees) and still connected to the service panel by a #4 or #6 stranded copper conductor. According to Electrical Code Simplified 2002, Ontario Book No.1, where there is no "continuously conductive metal water piping system", I may use Ground Rods - 10-702(3). Problems: 1.) Although one ground rod exists, it is not bonded to a second rod at least 10 feet (3m) away. 2.) The angle of the existing ground rod is due to ROCK, and I doubt that it reaches the required 4 feet at the lowest end. With a piece of rebar and a sledge hammer, I have tested the depth of the soil and I hit ROCK within 18". So, Concerns: 1.) Assuming I can find 10 feet of good earth for both rods (4+ feet angled), how far from the panel can the location of the actual rods be? 2.) Do I need 2 electrodes of 2 bonded rods each, or is the 1 #6 solid, continuous, copper conductor bonded to the 2 copper 1/2"/10 foot rods sufficient? 3.) What if I can't find deep enough earth? This is a serious life safety issue for me so I very much appreciate the help you are willing to give. Thank you in advance for your help!

Why dont you just call the permitting authority in your area and ask them ??

In the absence of a definitive answer from them I would proby just bury the rods as deep as I reasonably could and call it good.....

Better check on them remaining steel pipes, pretty sure theyre still sposed to be bonded to the ground lug at the service entrance panel.
