Field and Data Report, Downtown Portland Sediment Characterization Phase II

GSI and Hart-Crowser. 2010


This Field and Data Report provides the results of the second phase of the Downtown Portland Sediment Characterization (DPSC Phase II). The DPSC was initiated in 2008 (DPSC Phase I) to assess the presence of environmental contaminants within the downtown Portland reach of the Willamette River, tentatively defined as extending from River Mile (RM) 12 to 16. The Oregon Department of Environmental Quality (DEQ) performed a preliminary screening level evaluation of the Phase I data and identified nine Focus Areas for further investigation. Follow-up analyses of archived Phase I sediment samples were completed in response to the evaluation and in order to inform the development of sampling and analytical procedures for the DPSC Phase II. The analytical results for these archived samples also are included in this report.
