For a Cleaner Anacostia River - The Anacostia River Sediment Project

Remedial Investigation Work Plan

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 existing restoration efforts, DOEE is conducting a remedial investigation and feasibility study (RI/FS) of the Anacostia River sediments. The comprehensive and never-done-before remedial investigation is currently underway. Its purpose 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. The RI work plan is posted below, as well as responses to public comments on the plan. After the RI is complete, the FS will evaluate potential remedial actions.

Project Updates

DOEE completed round one of sampling in October 2014, which included over 400 samples of surface and deep sediment, sediment pore water, surface water, and benthic invertebrate and fish tissue. In late May 2015, DOEE finished a second round of sampling (more than 300 samples) near sites of concern in the Anacostia River. Analysis of this data is an on-going process, however, as validated data becomes available, the Department will include relevant reports on this page.

Round II Progress as of June 2015

River Sampling Activities Current Status %
Surface Sediment Sampling Complete 100%
Sub-Surface Sediment Sampling Complete 100%

See previous updates and approximate sampling point locations.

Related to the second round of sampling, the work plan addendum, attached below, shows the select sampling locations and describes the sampling rationale.

Community Involvement Plan

DOEE has also prepared a Community Involvement Plan (CIP) that serves as a planning tool to promote mutual communication between the public, stakeholders, and parties potentially responsible for the pollution, throughout the investigative phase and, any remedial cleanup phase. 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 Involved Plan is posted below, as well as responses to public comments on the plan.

Administrative Record File

The administrative record file provides public access to Anacostia River Sediment Project documents. The link below contains:

  1. Public comments and documents that demonstrate the public’s opportunity to participate in and comment on the ultimate selection of a remedy for the river and
  2. Documents that may be considered in ultimately selecting a remedy for the river.

To utilize the administrative record file, please open the index file within the link below, which provides a list of all documents and their respective locations within folders and subfolders.

Repository Sites

The DOEE is providing hard copies of the Work Plan and the Community Involvement Plan at three repository sites:
