| Short Description |
In July 1991, Ecology and PTI Environmental Services of Bellevue, Washington, sampled decanted water and sediment from Vactor Trucks operating in King and Snohomish Counties. Vactor Trucks are used to clean catch basins and other stormwater facilities. Sampling was conducted in high-density residential, commercial/light industrial, and heavy industrial areas to determine the effect of land-use on contaminant concentrations.

| Abstract | Long Description |
In July 1991, Ecology and PTI Environmental Services of Bellevue, Washington, sampled decanted water and sediment from Vactor Trucks operating in King and Snohomish Counties. Vactor Trucks are used to clean catch basins and other stormwater facilities. Sampling was conducted in high-density residential, commercial/light industrial, and heavy industrial areas to determine the effect of land-use on contaminant concentrations. Samples were analyzed for conventional water and sediment quality variables, metals, and organic compounds. Concentrations of metals, especially zinc, lead, copper, nickel, and chromium were elevated in decant water and sediment. In decant water, metals concentrations were associated with total suspended solids. Except for BTEX compounds, organics were infrequently detected in water. PAHs were the predominant class of organics in sediment. Pesticides and PCBs were not detected in any samples. Aside from high PAH concentrations in residential areas, most contaminants were highest in samples that originated from heavy industrial areas. |
