Thread: Old pressure treated wood

I have torn down an old deck & have 16 year old pressure treated wood that has never been stained or painted. Can this be used without harming anything for structure ? I know I have fished old sunken wood docks & caught plenty of crappie off them. They ate just fine to me.

would be reluctant at best to use it. even it will decay/ be consumed and the arsnic in it will be asorbed by lower life forms which are eaten by higher life forms. most small fish do not have high levels of toxins but they are concentrated in top predators...
