The 54 Cooperative piles at Coco Solo, Canal Zone and the 273 Cooperative and NCEL experimental piles at Pearl Harbor, Hawaii were inspected during the weeks of 9 and 23 March 1970, respectively. After 7 years of exposure at Coco Solo, 9 of the 12 piles treated with creosote-coal tar showed borer attack of varying degrees of severity. Only minor attack was noted on 2 of the 18 dual-treated piles. None of the Cooperative piles at Pearl Harbor was attacked by borers after 7 years but 33 of the 207 NCEL experimental piles showed attack by one or more Martesia after 3 1/2 to 6 years. Some were also attacked by Limnoria. The most severly attacked piles were those treated with CCA-Type B, chromated copper arsenate, by a commercial treater. (Author)
