: I manage a lumber yard Wolesale & Retail our main poduct is lumber for the marine indus. orCCA treated lumber. Now ACQ, now what I need is all the info i can gain as to the cons of ACQ Ive already heard the pros trust me. Thanks WOODY
Hi Richard,
You are quite correct that there are cons with ACQ in the marine environment. It is even more dangerous to aquatic life than cca wood is. Judith and Peter Weis have written many papers on this, below is a list of their studies and her contact can be found on my contacts page.
ACQ is not an acceptable alternative for cca wood as copper leaches greater in aquatic conditions than arsenic does.
