| Description | Juvenile Chinook salmon accumulate toxicants from streams in urban and developing environments that receive stormwater and wastewater discharges. This can affect Chinook salmon’s ability to survive in the marine environment due to increased risk of predation and disease. This Quality Assurance Project Plan (QAPP) describes upcoming investigations to identify potential point and non-point sources of emerging and legacy toxicants previously measured and currently impacting juvenile Chinook outmigrating from their natal habitats. In order to find the sources of toxic contaminants, we will sample the freshwater river systems along the salmon’s migratory pathway from the river mouth to upstream. We will use several monitoring techniques including: • Surface water sampling (using passive samplers and solid phase extraction). • Sediment sampling. • Sampling of resident biota (for example, algae/biofilm, and aquatic macroinvertebrates). The work will begin in the Snohomish River Basin where juvenile Chinook are impacted by polybrominated diphenyl ethers (PBDEs) — flame retardants found in household products. The intent of this QAPP is to provide an adaptable approach to continued investigations in other Puget Sound and Columbia River watersheds. |
