Migration of creosote components from timbers treated with creosote and processed using Best Management Practices

Abstract
While creosote components have very low water solubility, concerns have been raised about potential environmental effects and stimulated research to minimize migration. Best management practices have been developed but there are few data quantifying their effects. The effects of post-treatment steaming on migration of polycyclic aromatic hydrocarbons (PAHs) from horizontally oriented creosote treated southern pine decking subjected to simulated rainfall were examined. Twelve of the 16 PAHs examined were detected in runoff during the rainfall exposure but at concentrations well below those predicted by water solubility. PAH levels declined with increasing rainfall time, although the differences were sometimes slight. Steaming for 1 h had minimal effect on PAH levels in runoff while 3 h of steaming produced more noticeable reductions ranging from ~20 to 80% for naphthalene, acenaphthylene, and acenaphthene. Longer post-treatment steaming times reduced initial losses of creosote components from treated wood.
