| Study Purpose | Blue mussels (Mytilus spp.) and other sessile, filter-feeding bivalves have been used to monitor contaminant conditions in nearshore biota worldwide. In the past, mussel data from the National Oceanic and Atmospheric Administration’s Mussel Watch program, which collected mussels in the Puget Sound from 1986 to 2012, have been useful to broadly characterize ambient contaminant conditions in Puget Sound’s nearshore biota. In 2013 Washington State’s Regional Stormwater Monitoring Program (RSMP) initiated a program to monitor the status & trends of contaminants in the marine nearshore biota of Puget Sound, using transplanted mussels (Mytilus trossulus) as an indicator species. This status & trends monitoring follows a probabilistic sample design such that data gathered can be summarized across the Puget Sound ecoregion. In the winter of 2015/16, 40 randomly-selected marine nearshore sites adjacent to Puget Sound’s Urban Growth Areas (UGAs) were included for the first round of mussel monitoring. In addition, 25 sites were added to this mussel monitoring project through sponsorship by groups outside of the RSMP. This monitoring was implemented by the Washington Department of Fish and Wildlife’s (WDFW) Puget Sound Ecosystem Monitoring Program (PSEMP) team, which will evaluate and report on the contamination in mussels taken from the 40 randomly-selected sites as well as the 25 sponsored sites. Contaminants to be assessed include polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyl (PCBs), polybrominated diphenyl ethers (PBDEs), and range of chlorinated pesticides & metals.
Project objectives:
• Evaluate the range of chemical contamination in UGA shoreline biota, using blue mussels as the primary indicator organism.
• Measure the magnitude of contamination in mussels from the 40 sites and compare to known biotic effects.
• Provide recommendations for future status and trends monitoring with mussels to answer questions about stormwater management |
