| Abstract |
The Potomac River estuary was listed as impaired under Section 303(d) of the Clean Water Act due to the levels of polychlorinated biphenyls (PCBs) in the tissues of resident fish species. The impaired region includes the tidal freshwater portions of the Anacostia and Potomac rivers, and extends approximately 118 miles downstream to the mouth of the Potomac Estuary at Chesapeake Bay. As per a court order, a Total Maximum Daily Load (TMDL) for PCBs needs to be developed by the District of Columbia (DC), and approved by EPA no later than September, 2007. This project was complicated by many factors including the complexity of the system, limited available data on loadings and ambient concentrations, limited resources, and a very ambitious schedule. This report describes the development, calibration and validation of a PCB water quality model for the tidal freshwater portions of the Potomac and Anacostia rivers that was used to determine the PCB TMDL. The principal goals of the modeling effort were scientific understanding and management utility. The first goal involved gaining an understanding of the principal environmental processes influencing the transport and fate of PCBs in the Potomac and Anacostia. The second goal involved assessment of various PCB load reduction scenarios to determine the external PCB loads that can enter the system and still meet the applicable TMDL targets. To meet these goals the model must be scientifically credible and satisfy all regulatory requirements. |
