Ken-
Somewhere in the piles of info here is an article from one of the shelter
magazines from 5 years ago warning of the leachate threat from PT lumber. If I
find it I'll send it along. I know a guy upstate who has an "organic" herb
farm - on raised beds which are constructed with PT lumber! Why do all the
disclaimers that come with the stuff tell you to wash your hands after
contact?!
