Roy:

A couple of thoughts from my experience:
 
With regard to sources of the current in the pipeline; In the United
States all electrical distribution systems use the earth to carry
approximately 70% of the current back to the substations.  The current in
the earth throughout the country is significant.  Studies have been
conducted which show that the current on pipelines is, in general, not the
result of the malfunctioning of the distributions system but because of
the normal use of the earth as a major component of distribution systems.
In my work with dairy farmers throughout the country, it is clear that this
normal use of the earth as part of the distribution system is having a
serious impact on the behavior, health, and production of the cows and the
health of the people working on those farms.  Even though It is normal to
use the earth as a major current carrying conductor in the distribution
system it is certainly has become a real problem and is not right.
