In 1996, Forintek Canada Corp. set up a test of borate-treated lumber above ground, protected from rain but exposed to termites, in Kincardine, Ontario. The relative humidity ranged from 75 to 100% and the temperature ranged from -10°C to 20°C. The material included hemlock and amabilis fir lumber treated with borate and chromated copper arsenate (CCA). After seven years of exposure, generally all of the treated material was found to be performing equally well, with some pieces showing residual signs of earlier superficial feeding or cosmetic damage. Attack was moderate on untreated controls.
