| Short Description |
Recent sediment analysis in Elliott Bay, Washington, showed elevated polycyclic aromatic hydrocarbons (PAHs) near the Wyckoff wood treating plant. For this study, additional sediment samples were taken within 200 meters of the site to determine the distribution and severity of contamination. Relative abundance of individual high weight PAHs helped identify potential sources. Concentrations of metals (As, Cr, Cu, and Zn) associated with wood preservation were also examined.

| Abstract | Long Description |
Recent sediment analysis in Elliott Bay, Washington, showed elevated polycyclic aromatic hydrocarbons (PAHs) near the Wyckoff wood treating plant. For this study, additional sediment samples were taken within 200 meters of the site to determine the distribution and severity of contamination. Relative abundance of individual high weight PAHs helped identify potential sources. Concentrations of metals (As, Cr, Cu, and Zn) associated with wood preservation were also examined. Comparatively high concentrations of PAHs were found in subtidal sediments near the Wyckoff facility (total PAHs at one location exceeded 1000 ppm dry weight). Concentrations increased toward the Wyckoff Company, implying this facility is the probable source of PAHs. Seven of 16 samples exceeded the highest Apparent Effects Threshold (AET), which indicates biological problems are likely to occur at the observed PAH concentrations. PAHs, pentachlorophenol, and high concentrations of metals were found in two monitoring wells onsite, indicating migration of wood preservative into the groundwater. |
