This technical memorandum presents a summary of the sampling for polychlorinated biphenyls (PCBs)<\/SPAN><\/P> conducted in 2020 in Lower Beaverdam Creek (LBC), in Prince George\u2019s County, Maryland by the<\/SPAN><\/P> Maryland Department of the Environment (MDE) Land Restoration Program (LRP). Field activities for this<\/SPAN><\/P> investigation included sediment, surface water, and fish sampling. The objective of this sampling is to<\/SPAN><\/P> further refine the conceptual site model for the PCB contamination that was found previously in LBC<\/SPAN><\/P> sediment and surface water in November 2019, and to aid in the ongoing source track-down effort in<\/SPAN><\/P> the LBC watershed.<\/SPAN><\/P> MDE conducted surface water and sediment sampling for PCBs along the entire length of LBC in<\/SPAN><\/P> November 2019 (MDE, 2021). Both surface water and sediment data indicated two primary areas of<\/SPAN><\/P> concern for PCBs in LBC: the stretch of LBC parallel to Pennsy Drive (just north of the Landover<\/SPAN><\/P> Road/Route 202 bridge), and the area adjacent to the I-295-US-50 Interchange. To further delineate<\/SPAN><\/P> these two areas of concern, additional sediment and surface water sampling was conducted in these<\/SPAN><\/P> areas in August and September 2020. In addition, in October of 2020, small fish were collected for<\/SPAN><\/P> analysis of PCBs in fish tissue. <\/SPAN><\/P> <\/P> <\/P> * A sample was not able to be collected from OF-12, or between the outfall and the stream, so this <\/SPAN><\/P> sample was taken in creek sediments where the outfall spills. <\/SPAN><\/P> ** These samples were analyzed via EPA Method 1668. <\/SPAN><\/P><\/DIV><\/DIV><\/DIV>",
