Abstract: Sources of toxic chemicals in storm drains are often difficult to locate and even more difficult to control. Receiving environment chemistry, storm drainage maps, land use information, and sampling of sediments in storm drains, can be used to identify significant sources of heavy metals and organic toxicants from commercial and industrial facilities. Once runoff contaminated by past and present practices is controlled, in-line sediments can be removed from the drains to prevent further degradation of the receiving environment.
