You are correct that you shouldn't use pressure treated lumber if you are going to raise anything edible, but it's fine to use for non-edible plants.

I went to Hawaii shortly after posting this question... we were hoping cedar would work....

I'm raising vegetables and fruits in beds bordered with logs. Potatoes last year, garlic and melons this year. They were here when I bought the house, and I guess they might be pressure treated. They're the standard border logs. Along with those, I'm going to also have raised beds this year, with plastic panels and bought soil.

All are hazardous to human health and the environment and do not break down into harmless substances." "There is also evidence of arsenic leaching from CCA-treated wood into the surrounding environment. Leaching of arsenic from PT CCA wood in raised garden beds has been found to be limited to about 6", but that 6" is permanently contaminated. It means that you should not grow vegetables in that strip nor can you turn that soil into the rest of your garden. It also means that that soil is still contaminated long after you and your garden are gone." "Only small amounts of these compounds are taken up in vegetables grown in contaminated soil. These amounts are generally considered too small to be immediately toxic. However, the effects of repeated exposure to these low levels are not well understood."

Like so much in life. http://www.google.com/search?q=is+pressure+treated+wood+safe+for+vegetable+ gardens&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefo x-a Cindym - LA, Zone "8b"
