Sixty-six 20-foot piles cut from 40-foot Class B Douglas fir piles were treated with creosote-free preservatives containing combinations of compounds in the NCEL wood treating plant. Twelve piles were treated with two of these solutions to which some creosote was added. Retentions of preservative were determined by weight increase. The treated piles are being exposed at Waipio Point, Pearl Harbor, Hawaii. Author
