Permalon is the way to go, but when I priced it, it was more than EPDM.
Permalon is HDPE, and is one of the strongest, lightest liner materials
available for use today. Also has great UV resistance. It has a 20 yr plus
guarantee as well.
I didn't get into a discussion of it, only because the questions posed were
EPDM PondGard vs EPDM Rubbergard.
Happy ponding,
Greg
(I ordered the EPDM above because 2 of our club members insisted on it, not
wanting either Permalon or Xavan)

30x50 liner... that went 474 pounds each

So why not permalon and you won't have to worry about leaching at all.
And man, it's a heck of a lot lighter than that. 474 pounds... I can
roll 500 lbs, but it could roll me (flat), too. 30x20 permalon I could
pick up and toss around, easy.

I've got pond gard up in the filter but the rest is permalon, factory
direct at $0.22 sq ft (1997).
