Stormwater Action Monitoring (SAM) conducts status and trend monitoring in Western Washington streams and nearshore marine waters.
This study of contaminants in urban nearshore caged mussels is led by the Washington Department of Fish & Wildlife (WDFW) and sample collection will take place over two winters. The first round of sampling was winter of 2015/16 and a second round in winter 2016/17.
Study goal and expectations
The goal of this study is a status assessment of contaminants found in biota in the Puget Sound urban nearshore.
WDFW presented preliminary findings and recommendations to shape the mussel trend monitoring at the June 1, 2017 SAM Symposium and are also given in the final report. The Stormwater Work Group (SWG) will make adjustments to the SAM mussel trend monitoring program based on recommendations from the report and further discussion by the SWG's technical committees.
