Most helium is found mixed in with natural gas. It is a limited resource, since there is only one mechanism for replenishing helium, and that is alpha radiation decay. An alpha particle is two protons and two neutrons, which is a helium atom nucleus. If it manages to acquire a pair of electrons, it becomes a helium atom.
Huckleberry: Biogas contains methane and hydrogen, both lighter than air. Other components are carbon dioxide (moderately heavier) and hydrogen sulfide (significantly heavier and the source of the stink). It still totals slightly lighter.

How do the trucks even stay on the ground?

Ok, now. Hands up everyone who knows where they mine helium from. :)

Night-Gaunt: The primary part, it is still crude biogas.
