Do we have the equipment to do a chemical composition analysis of old pressure treated wood? Assuming we do, would someone be willing to help me test a wood sample? Willing to trade/pay for the help as it would be more fun to learn how to do the testing than a send away kit or home kit.
Reason why, I am replacing my deck of unknown age and would like to reuse the 2x6s for a raised vegetable garden. But I don’t know if the wood was treated with an arsenic like CCA or ACZA, or whatever else is in it for that matter.
