Sorry for the confustion. YES, it does end up on a clamp on a water
I don't know enough about this stuff to tell you the gauge. He had a
huge spool of green grounding wire and it is not flimsy at all. Does
the green coating count as "conduit" as you termed it? In any event,

Some people have misinterpreted what he's done. He is attempting to ground
an ungrounded outlet. He's not intending to ground your electric service.
Regardless, his work was sloppy and incorrect by current NEC
A substantial copper wire in direct contact with the dirt is OK. The
water pipe that he connected to is probably part of the grounding

problem I see with this is the wire is not protected from someone
cutting it with a shovel if they dig there.
