It certainly depends upon location. At my previous QTH,
the horizontal dipole was, on the average, 2 S-units
quieter than the 40m vertical. I tracked the noise to
a 30 foot ground wire running down a power pole.

I would think that means a bad connection somewhere near
that point. Could be the wire connection to ground itself,
or a bad part somewhere near that area, and the ground
wire was just acting as an antenna extension to the bad
part. Many parts can develop bad or leaky connections and
start to cause noise. It was a bad end connector once when
I had to call the power co.
Make sure the ground wire is actually connected to ground
well, and if it still makes noise, try banging the power pole with a
sledgehammer while listening on a portable radio.
If the noise changes, it's fairly close in that area.
Or if you use a radio with a directional antenna, you might be
able to get fairly close.
Once you get that close, nothing to do except bug the power
company.
