The District of Columbia has released the first steps of a plan to clean up a legacy of toxic contaminants on the bottom of the Anacostia River.
The “early action” plan calls for capping, dredging and monitoring contaminated sediment at nearly a dozen “hot spots” along a highly urban and historically industrial nine-mile stretch of the river, which flows from suburban Maryland through the nation’s capital.
The District Department of Energy and Environment will hold the first of several public meetings to explain the proposed plan on Thursday, Jan. 23, from 6:30 to 8:30 p.m. The public comment period for the plan was extended to March 2, with additional meetings to be held on Jan. 27 and Feb. 3.
The main ways people would be exposed to these contaminants is by wading or swimming in the river or by fishing and eating contaminated fish tissue. It is currently illegal to swim in District waters, and anglers are advised to limit their consumption of locally caught fish, especially bottom-feeders from some portions of the river. But a 2013 report found that many residents consume significant amounts of fish caught in the Anacostia anyway. Fish, aquatic insects and other wildlife also are impacted by the chemicals in the river’s sediment, which can become resuspended in the water when the bottom is stirred up.
The proposed plan predicts the work will yield a 90% reduction in people’s risk of exposure to PCBs from eating contaminated fish.
“The idea here is that if we clean up the most contaminated areas, the presumption is you’re reducing the risk,” said Dev Murali, remedial project manager with the District. Follow-up monitoring is planned to gauge the cleanup’s effectiveness.
The project is estimated to cost about $30 million. The District government is funding the first steps of the sediment cleanup, though the city will likely seek to recover remediation costs from companies and federal agencies that contributed to the pollution.
