Interview audio has a low hum only on the lav, boom track is clean

Almost certainly induced hum rather than a ground loop, and the head-turning detail is what tells you. A lav cable running near mains, a dimmer, a fluorescent ballast or a laptop charger acts as an antenna, and body position changes the coupling. Fixes in order: find and kill the offending device, because dimmers are by far the worst offender, reroute the cable away from mains and cross it at right angles if you must cross, and if your recorder is plugged into the wall, run it on batteries instead. Notching 50 or 60Hz also mangles the harmonics, so five minutes at the source is worth it.
