Treated wood

[longwinters]

In a previous thread there was mention of using "treated wood".  I did some fairly extensive research a year ago and found that the new types of treated wood are not like the arsonic treated wood of years past.
 
So I guess my question is, has anyone checked out the new types of treated wood insofar as gardening goes?

my backyard island is surrounded by treated wood.  that where the grass grows the thickest.
