At our facility they used a device called a MEGGER to test earth ground integrity. (dont ask me to explain exactly how it operates, its been tooooooo long and Im too busy to look it up lol perhaps others might have the time) We were a Federal US Navy Base and our rules were to drive one earth ground rod and if it failed the megger test to drive another, but if it still failed we werent required to drive a third. Before anyone has a calf Im NOT saying to do that or its right for your area or NEC proper Im ONLY saying those were the rules where I practiced and your area may do it differently
HOWEVER ITS NOTTTTTTTT WHAT MYSELF OR ANY ENGINEERS OR ELECTRICIANS OR LAY PERSONS OR ANY KNOW IT ALL BILLY BOBS SAY THAT MATTERS, ITS WHAT THE LOCAL AUTHORITY SAYS ABOUT THE ESTABLISHMENT AND TESTING AND INTEGRITY OF GROUNDING ELECTRODES THAT MATTERS
If in doubt Id consult the local authority and take a look at the NEC for guidance. While its NOT any legally binding document, its probably more dependable then professional let alone lay opinions rendered here if youre going to bet your life on how to do things...
