Santa Margarita Estuary 2022 Sediment Monitoring Report (Project PEMEC2743)
Abstract
This report describes results of sediment monitoring conducted in the Santa Margarita River Estuary (SMRE) located on Marine Corps Base Camp Pendleton (MCBCP) in 2022, performed on behalf of MCBCP Environmental Security(ES) Staff, in support of their Municipal Watershed Monitoring Program (MCBCP, 2020). Sediment monitoring was conducted at three (3) locations on 12 July 2022, during the summer index period, following the analytical techniques and quality controls/assurances as required under the Sediment Quality Assessment Technical Support Manual and as specified under the SMRE IO Workplan and Quality Assurance Project Plan. Samples were analyzed for standard sediment quality characteristics and benthic community composition, and were tested for toxicity with marine amphipods (Eohaustorius estuarius) and Mediterranean mussel (Mytilus galloprovincialis) embryos using standardized protocols. This report describes the methods, results and data evaluation used to meet the monitoring goals following the California Sediment Quality Objectives line of evidence framework to assess sediment quality using these various metrics.
