As of January 1, 2004, EPA will not allow CCA products to be used to treat
wood intended for any residential uses such as play-structures, decks,
picnic tables, landscaping timbers, residential fencing, patios and
walkways/boardwalks.

Should we use them where they might bleed into a pond? I also wonder if we
should be tossing them into compost piles. :)
I'm probably at greater risk standing near bus exhaust. Is concern about
pressure treated timbers unnecessarilly alarmist when considering their
impact on ponds or streams?
Thanks and all the best!
