CCA (Chromated Copper Arsenate)

Common questions about CCA:

Why was the use of CCA discontinued for residential and general consumer use?

In recent years pressure treated wood received negative publicity mainly focused on the use of arsenic in CCA. The increasing pressure to eliminate the use of CCA resulted in the treated wood products industry voluntarily transitioning from CCA to alternative preservative systems.

CCA is no longer being produced for residential or general consumer use.

What products are still manufactured using CCA?

CCA treated wood products are still produced for use in some industrial, highway, and agricultural applications. These uses will include wood used as poles, piles, guardrail posts, and wood used in saltwater marine exposures.
