    1.0 INTRODUCTION

    As part of the Round 2 benthic tissue sampling effort, the U.S. Environmental Protection Agency (EPA) requested the Lower Willamette Group (LWG) to retain any lamprey ammocoetes collected in the Study Area and mussels collected as bycatch at five sampling locations (Windward and Integral 2005). During the field effort in November and December 2005, lamprey ammocoetes were collected at nine locations. Mussels were collected at four of the five requested locations and at an additional 15 locations in the Study Area. A detailed description of the Round 2 benthic tissue collection effort is included in the field sampling report (FSR; (Windward 2006). In accordance with the field sampling plan (FSP; (Windward and Integral 2005) and as discussed in the FSR (Windward and Integral 2006), all mussel and lamprey ammocoetes collected during the R2 benthic tissue sampling effort were archived frozen at -20 °C until analytical schemes for each tissue matrix were approved. Mussel and lamprey tissue samples were composited and analyses selected as described in Section 3.1 of this report.

    The remaining sections of this document include a summary of the data collection activities (Section 2); details on the laboratory sample analyses, data quality reviews, data management, and laboratory deviations (Section 3); results (Section 4); and references (Section 5).

    2.0 SAMPLE COLLECTION ACTIVITIES

    This section summarizes the Round 2 benthic tissue collection activities during the 2005 sampling event. Station navigation and positioning, record keeping, and sample handling and storage details are presented in the FSR (Windward and Integral 2006).

    Sampling of clams (Corbicula sp.) was conducted at 33 locations within the Study Area between river mile (RM) 2 and RM 10 in November and December 2005. In accordance with the FSP, all lamprey ammocoetes and mussels collected at the 33 locations were retained for possible chemical analysis (Windward and Integral 2005). One to two lamprey ammocoete individuals were collected at nine locations (Table 2-1). Mussels were collected at 19 locations with numbers ranging between 1 and 7 individuals (Table 2-2). The majority of the mussels were tentatively identified as Western pearlshell mussels (Margaritifera falcata); only a few individuals (5) collected at BT007 and BT009 were tentatively identified as winged floaters (Anodonta nuttalliana).

    Chemical analysis was performed on the composite lamprey ammocoete sample and seven mussel tissue samples collected at stations BT001, BT004, BT006, BT009, BT021, BT025, and BT033. Chemical analysis was not conducted on two of the mussel samples requested by EPA because the sample collected at BT017 consisted of one mussel that turned out to be an empty shell and the other sample collected at BT015 consisted of only one mussel.
