Abstract
Air-seasoned Sitka spruce was treated with ammoniacal copper zinc arse nate (ACZA) or chromated copper arsenate (CCA) at 11 commercial plants . Preservative retention and penetration were greater with ACZA treatm ents. All but 2 of 14 charges treated with ACZA met the American Wood Preservers' Association specifications for treatment of lumber in grou nd contact. Despite incising, none of the CCA treatments reached the r equired depth of penetration, and only 3 of 15 CCA charges achieved th e desired chemical loading.
