CCA stands for Chromated Copper Arsenate. Over the past few years, there have been an increased number of concerns about potential negative health effects of this wood preservative containing arsenic. As a result, the wood-treatment industry voluntarily transitioned away from CCA-treated wood to alternative treatments for residential construction applications. CCA will remain in use for some industrial, agricultural, and marine applications.
