Arsenic-treated wood is the result of a chemical process in which wood is treated with a pesticide/preservative called chromated copper arsenate (CCA) to prevent rotting in lumber designed for outdoor use. CCA contains arsenic, chromium, and copper and was widely used for residential purposes in the United States from.
Long term exposure to drinking water containing arsenic at levels higher than 10 ppb increases the chances of getting cancer; for lower levels the chances are less.
