Biosphere II is constructed so that the only things that get
in and out are energy.  It has a plastic laminated base that
is somewhere between 10 - 20 feet below ground.

There is a very detailed (and very good) discussion of Biosphere II
in the last issue of the Whole Earth Review (not the current one,
but the one before).  Fascinating stuff.
