Abstract : The Navy is considering alternative wood preservatives that are environmentally acceptable. In order to determine the effectiveness of wood preservatives in the marine environment, the Naval Civil Engineering Laboratory (NCEL), in cooperation with industry, installed pilings with test preservatives in Pearl Harbor, Hawaii, in 1963 through 1966 and has observed and evaluated the preservatives. Certain chemicals, such as the chlorinated hydrocarbons, chlordane, and dieldrin, have demonstrated outstanding presersvative qualities; the use of such presersvatives, however, in the marine environment is subject to EPA restrictions. Basic zinc sulfate is an environmentally acceptable preservative that appears to show promise; its effects on the mechanical properties of wood should be more thooughly investigated.
