| Abstract | Long Description |
Priority pollutant metals and organics concentrations were measured in freshwater discharges, intertidal sediments, and clam tissues from McNeil Island to determine if contamination documented on the island has migrated into Puget Sound. The level of chemical contamination was found to be generally low and in the range of values typically reported for reference (background) areas of Puget Sound. An exception was sediment from the outlet of Eden Creek Reservoir which contained elevated concentrations of arsenic, chromium, lead, and polyaromatic hydrocarbons. Chromium and polyaromatic hydrocarbon concentrations in sediments from this site exceeded the 90th percentile level reported for sediments from urban areas of Puget Sound. |
