Baseline stations are classified as "urban", "near-urban" or "non-urban",
based on their proximity to urban centers or industrialized areas. Because
of the complex, unmeasurable factors associated with describing the contaminant-condition
of sediments, we use this subjective classification scheme. The urban
locations represent some of the largest cites along the Puget Sound shoreline.
The non-urban areas are situated far from these cites, greater than 10
km and often separated by deep basins. Near-urban locations are between
urban and non-urban.
Where possible, monitoring
stations were located near sediment quality stations (sampled by the Department
of Ecology) to facilitate correlation of sediment chemistry with muscle
Focus studies have been carried out in Elliott
Bay, Commencement Bay and Sinclair
Inlet to further characterize the areal extent of contamination
and associated biological effects in English sole. Focus stations
were distributed so as to expand the spatial coverage around the
baseline station of interest. Click the preceding station names
for detailed maps of the Focus Study sites.
Historic stations are those at which PSAMP has discontinued sampling.
