Abstract

Seattle Public Utilities (SPU) has been tracking PCBs in City-owned storm drains that discharge to the Lower Duwamish Waterway for the past 10 years. Source tracing efforts have utilized samples of sediment that has accumulated in drainage pipes and associated structures (e.g., catch basins, maintenance holes, and vaults) to identify sources of contaminants to the system. This presentation will provide a few source tracing success stories and describe lessons learned by SPU.
