The average retention for 54 pentachlorophenol (PCP) treated white spruce poles easily exceeded that required by the Canadian Standard Association (CSA) wood-preservation pole standard in pressure-impregnation tests. In the same series of tests, ammoniacal copper arsenate (ACA) - treated white spruce poles exhibited excellent penetration of preservative, but analysis by X-ray spectrometry revealed only six of the 106 poles contained sufficient preservative to achieve the level established by the CSA standard. The majority of the PCP poles showed a preservative penetration within the range 0.5 to 1.0 in.
