Description Contaminated soil and sediments from upper and lower segments of Little Squalicum Creek were evaluated in accordance with applicable regulations WAC 173-340 and WAC 173-204 for determining whether they present a threat to human health and the environment. Sediment samples were tested for toxicity using amphipod (10-day Hyalella), midge (20-day Chironomus) and Microtox bioassays. Sediment and soil samples also were analyzed for semivolatile organic compounds, including polycyclic aromatic hydrocarbons (PAHs) and pentachlorophenol.

At four of the five sediment sampling locations, bioassay Cleanup Screening Level endpoints were exceeded. At both soil sampling locations, carcinogenic PAHs exceeded Method B Soil Cleanup Levels.
