Demonstration Site
The Anacostia is one of America's most endangered rivers, with sediments containing significant concentrations of heavy metals, polychlorinated biphenyls (PCBs), hydrocarbons, and chlordane. Likely sources of these contaminants are long-term military and industrial activity in the Anacostia and Potomac Rivers.
The demonstration will make use of two study areas on the Anacostia adjacent to the Navy Yard:
Site 1
This old CSO on the south end of the Navy Yard has 6-12 parts per million (ppm) of polychlorinated biphenyls (PCBs) and 30 ppm of polyaromatic hydrocarbons (PAHs). Metals on site include:
- Cadmium: 3-6 ppm
- Chromium: 120-155 ppm
- Copper: 127-207 ppm
- Lead: 351-409 ppm
- Mercury: 1.2-1.4 ppm
- Zinc: 512-587 ppm
Site 2
This site is near an old manufactured gas site on the north end of the Navy yard. It has PAHs up to 210 ppm.
