Moved to Kentucky last year and want to put in a small garden. House I bought had an above ground pool with a deck and I was going to remove the deck surface and leave the posts for a fence to keep the deer out (Daniel Boone Nat'l Forest adjoins my lot). While checking out the deck and deciding on what I needed to do discovered a tag on the pressure treated lumber used. It is the type that was treated with arsenic and the tag had all sorts of warnings. Concerned that over the last dozen or so years arsenic may have leached into the soil and if so would be absorbed into anything I grow. Anyone have any experience with this situation?
