CCA Treated Wood 
In response to several inquiries about CCA 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. This page represents one subtopic, other topics are available at the main index page.
For information concerning non-CCA treated wood (ACQ, creosote, pentachlorophenol, borates) please see our Non-CCA Wood Preservatives page.
