Description Two surveys of the Lower Duwamish Waterway sediment cleanup site were conducted in 2006 to see if SPI results could predict regulatory indicators of sediment quality. Based on this limited study, SPI parameters did not appear to predict sediment quality as defined by numeric sediment quality standards and cleanup screening levels. However, different benthic infaunal communities were identified, and SPI results helped to distinguish between them.

Recommendations were to (1) arrange for more analysis and review of findings, (2) conduct more studies at other cleanup sites, and (3) use SPI more often in early cleanup site investigations, and (4) incorporate latest scientific knowledge about how to assess the health of benthic communities into such investigations.
