CCA Treated Wood 
In response to several inquiries about the potential health concerns associated with CCA (copper, chromium and arsenic) treated wood, NPIC presents this collection of science-based articles, fact-sheets and resources. Our goal is to promote informed decision-making based on sound science.
The topic headings below were chosen because they were the areas that generated the most interest by people who contacted NPIC.
