The impact of the use and disposal of creosote impregnated railway ties on a freshwater supply area in southern Finland

Creosote was widely used and is still used as wood preservative and can therefore be a hazard to the environment. It is therefore necessary to improve the disposal of impregnated railway ties and to check for PAH compounds before taking a new water supply into use in areas where creosote impregnated wood has been handled or stored.
