For a Cleaner Anacostia River - The Anacostia River Sediment Project


Tuesday, December 6, 2016


Decades of industrial and urban activities throughout the Anacostia River’s watershed have increasingly degraded the river and caused the substantial loss of tidal fringe wetlands and marshes. Elevated concentrations of hazardous substances, including polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), lead, other trace elements, and pesticides are all present in sediment throughout the river, posing a risk to aquatic organisms and to humans. To complement and supplement previous and current restoration efforts, DOEE is conducting a remedial investigation and feasibility study (RI/FS) of the Anacostia River sediments. The purpose of the RI is to assess the nature and extent of pollution in the river by sampling river sediment and fish for a wide variety of chemicals. As part of the RI, studies will also integrate sampling and data collection to support a study for the Natural Resources Damage Assessment (NRDA) of the river. After additional RI work is complete, the FS will evaluate potential remedial actions.

Project Updates

Phase 2 Remedial Investigation Work Begins

In the summer of 2016, the Department began field work on the second phase of its remedial investigation for the Anacostia River Sediment Project, to address data gaps identified in the March 18, 2016 Draft Phase 1 Remedial Investigation Report. The work plan that the Department used to perform much of the work can be found below and in the Administrative Record file.

Phase 1 Draft Remedial Investigation Report Released for Public Comment

Prior to beginning the performance of the Phase 2 RI, on March 18, 2016, the Department released the Draft Phase 1 Remedial Investigation (RI) report for public comment. The report presents the results of the remedial investigation that studied the tidal portion of the Anacostia River, including the river from its confluence point with the Potomac River to the northeast and northwest branch of the river. It also includes Washington Channel and Kingman Lake. DOEE studied surface sediment, subsurface sediment, surface sediment pore water, surface water, benthic tissue, and fish tissue by collecting and analyzing more than 900 samples.

As part of the Phase 1  RI,  DOEE performed an ecological and human health risk assessment, to analyze whether site contaminants pose a current or potential risk to ecology or human health in the absence of remediation.

The public comment period for the Phase 1 RI ended on May 10, 2016. The Department reviewed and considered all comments received and is working on revising the Draft Phase 1 RI Report pursuant to the comments. The Department also considered comments received as it related to work performed under Phase 2 of the remedial investigation.

If you have any questions or comments on the Anacostia River Sediment Project, please contact Dev Murali, Remedial Project Manager at dev.murali@dc.gov.

Community Involvement Plan

For the public, stakeholders, and parties potentially responsible for pollution, DOEE has also prepared a Community Involvement Plan (CIP) for the Anacostia River Sediment Project that serves as a planning tool to promote an open dialogue throughout the Department’s investigation and during any remedial cleanup. DOEE is fully committed to involving the public in every phase of the investigation and cleanup efforts in a substantial and significant manner to meet established goals. The Community Involvement Plan is posted below.

If you have any questions regarding community involvement for the Anacostia River Sediment Project, please contact Gretchen Mikeska, Anacostia Coordinator at gretchen.mikeska@dc.gov.
