ERM = effects range median (Long et al., 1995)
' SQS = sediment quality standard, CSL = cleanup screening levels (Washington State Sediment Management
Standards - Ch. 173-204 WAC)
' Trace metal data derived with strong acid digestion were used for comparison to ERM values while those derived
with hydrofluoric acid digestion were used for comparison to SQS and CSL values
he LPAH criterion represents the sum of the Naphthalene, Acenaphthylene, Acenaphthene, Fluorene,
Phenanthrene, and Anthracene values
* = calculation includes all values which exceed guidelines or standards, including those that were at or below the
quantitation limits reported by Manchester Environmental Lab
>QL only = calculation includes all values which exceed guidelines or standards, excluding those that were at or
below the quantitation limits reported by Manchester Environn~ental Lab
NA = no guideline or standard available
