| Description | The recovery of Puget Sound Chinook salmon populations is in part measured by the reduction of contaminant levels in juvenile Chinook. This key indicator of the health of the species population continues to not meet the goal of a declining trend in contaminant levels for 95% of juvenile Chinook sampled by 2030. During the last (2016) Puget Sound monitoring, juvenile Chinook from four of the 11 river estuaries continued to not meet recovery targets for tissue burdens of toxic chemicals (toxics). Because juvenile Chinook from the White-Puyallup watershed did not meet target levels for PCBs and PBDEs, the state departments of Fish and Wildlife and Ecology are planning further monitoring to determine the sources of these contaminants. The investigation of potential point and nonpoint sources of PCBs and PBDEs in the White-Puyallup watershed is needed to meet 2030 recovery targets through the reduction of toxic inputs into juvenile Chinook habitats. This document describes the up-coming study which will sample freshwater and estuarian environments in order to determine sources of toxics impacting juvenile Chinook along their migratory pathway from natal streams to the near-shore environment. We will use several monitoring techniques including: • Integrated surface water sampling (passive samplers). • Sediment sampling (benthic/suspended). • Sampling of resident biota (aquatic macroinvertebrates). This document is an addendum to the most recent Quality Assurance Project Plan (Hobbs, 2019) and provides updated information specific to sampling of the White-Puyallup watershed (WRIA 10). |
