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