Hi Papa Vic,
A local lumber yard gave me the same info. I realized that it is his job to sell lumber, so I pleasantly heard him out. He told me, "We remove the arsenic and other poisonous chemicals before we sell it to you". Hmmm. No that makes me feel safe.
Am I going to use treated lumber based on the sales rep info., NO WAY. I really would like to see a study regarding treated wood and vegetable gardening. If anyone has any information, please share.
