RE: Use of treated lumber not recommended for vegetable

S* H*

To add to the evidence that Greg L. posted, I am providing the link to the 
actual first research done at the U of MN--reported this summer.

Also, at a Master Gardener Conference I attended this fall where the 
primary researcher was presented these results, I learned that the mining 
required for the ingredients needed to make CCA lumber is an issue.  So has 
been the poor disposal methods that have historically been done with CCA 
treated lumber.  Without going to my course  notes, I cannot post the 
specifics, maybe someone else knows these details. If I can get to them, I 
will repost. They were definitely NOT sustainable nor green practises and 
really should be countered through reducing  the demand for this material.
