[email protected] ABSTRACT A jointly sponsored study by Environment Canada, Fisheries and Oceans, the Province of British Columbia and the wood treatment industry was undertaken in Sooke Basin, Vancouver Island to evaluate the impact of creosote treated wood on the marine environment. The primary purpose of this study was to provide a scientific basis for establishing guidelines on the use and placement of creosote treated wood in sensitive marine aquatic habitats under ‘worst case’ conditions. The study focused on the chemical and biological effects from newly installed six- piling dolphins constructed with used pilings treated by conventional methods and pilings freshly treated with techniques designed to produce a cleaner and more environmentally sensitive product by placing them in a natural undisturbed location, free from outside sources of contamination.
