Title: Changes in Pressure-Treated Wood for Residential Construction

Abstract: Wood treated with chromated copper arsenate (CCA), commonly called ?green-treated? wood, dominated the residential market for several decades and was sold at lumberyards under a variety of trade names. However, as the result of voluntary changes submitted by CCA registrants, labeling of CCA by the Environmental Protection Agency (EPA) now permits the product to be used primarily for industrial applications. Use of wood treated prior to 2004 is not affected by this change. This development has raised questions about the availability of CCA-treated wood and the properties of alternative types of treatments.
