As Jeff points out, the EPDM can be used for roofing, but is it also
commonly used for pond linings.  Shops that sell supplies for building
ponds sell it by the foot off 12 or 15 ft wide rolls. I think that is
runs roughly $ per sqft.  I believe it to be good for temps as high
as 180F -- but, you might want to do a confirmation on that.

The rigid foam boards are good for quite a bit of bearing.  I think
that Nick has said up to 30 psi(?) -- that would be about 60 ft depth
of water, so should be OK :-)

I am planning to just dig the hole in a basically rectangular shape
with sides that have about a 60 degree tilt.  I'll then just cut 2
inch thick foam board pieces to fit, using at least two layers.  And,
using the polyurethane foam in cans to seal the joints.  I figure that
the foam board will just deflect until it is supported by the dirt
walls and bottom.
