Typically wells make for less impressive grounds than one might initially think. Firstly, the
metal casing doesn't go all the way down, usually only as far as it takes to hit reasonably solid rock that will hold a bore; even then perhaps only the top length (20 feet) will be metal, the rest plastic. The metal is usually untreated steel, which protects itself with a
layer of rust;  makes for a lousy electrical dirt/pipe interface.

and in Canada most provincial electrical codes REQUIRE the well casing be bonded to the common electrical ground as there can occasionally be a rather large electrical charge built up on the often well insulated from ground steel well pipe casing.
