Kent,
A problem you haven't considered is once you solve the "interference" from 60 Hz, you'll have to deal with the "interference" from 180 Hz.
Attached is a spectrum view of a 60 Hz signal at a location in Western Oklahoma from February 1999. I've only included the primary to the fourth harmonic. I have a panoramic view out to the 24th harmonic and will include that upon request.
Your problem may not be as simple as getting rid of the 60 Hz and taking a reading on the signal of interest.
