Description: Freely-dissolved PCB concentrations in the tributaries were lower than those in the Anacostia River, with the exception of Lower Beaverdam Creek (LBC), which exhibited PCB levels up to twenty times higher than the concentrations than the Anacostia River. Freely-dissolved concentrations in water phases (water column and sediment porewater) were similar between Summer 2016 and Summer 2017, but seasonal changes were observed with notably a factor of two decrease in the water column from Summer to Fall 2017. For all tributaries and the river, PCB concentrations measured were above the EPA Water Quality Criteria for Human Health protection for the consumption of water and organisms (0.064 ng/L; at 1 in a million incremental risk of cancer) throughout the seasons.
