Hi Irv,
In fact you had the perfect opportunity to do simple but effective
test through a classic three electrode measurement.
You perform the test three times by rotation among the three
electrodes. You apply a HIGH voltage across the two most distant
electrodes, measure that current, and measure the potential difference
to the third, middle electrode. You must us a high voltage to
overcome local ground currents and any cathodic action. 50 or more
volts is enough.
