This article, or at least part of it, could have been titled “Danger on Dock” or maybe “Danger under Dock.” After reading about how chromated-copper arsenate (CCA) is leached from the wood, I began wondering how it affects aquatic organisms. Many fish, especially bluegills and other sunfish, make these docks their preferred habitat. If not eaten directly by humans, they are caught and used for bait, eaten by bigger fish, or consumed by other wildlife.
