Seems to me that during my last trip to Home Depot I saw a notice on the treated
lumber that it no longer contains the toxins that once were present. Might be
worthwhile to check it out.

I am making a new garden and was planning to put treated 4X4 lumber around
the perimeter. Someone mentioned not to use it because the chemical will
leach into the soil and contaminate the vegetables which may cause cancer. I
would appreciate your opinions on this matter. Thanks
