pressure treated wood
I'm replacing old deck planks. The old ones are at least twelve years old and are now dry rotting. They were not 5/4 decking, just 1 x 6 planks. I don't know if they were PT or not. I'm testing them for arsenic. If that is the case, they go to the landfill. If they are newer non arsenic, I'm not sure if they are burnable or not, nor do I know how to test for that. Is there a test for that?
If they are not PT, they will be bonfire fodder.
