Site History

Prior to 1882, the area that became Poplar Point was compromised of tidal marshes associated with the Anacostia River. Between 1882 and 1927, sediment dredged from the Anacostia River was placed into these tidal marshes to create developable land. From the mid-1920s until 1993 the western portion of the approximately 96 acre Poplar Point Site was divided into two parcels, both of which were used for plant nurseries and greenhouses. One of those parcels was used by the District of Columbia’s Lanham Tree Nursery (DCL), and the other by the Architect of the Capitol (AOC). From the 1940s through the 1960s, the Naval Receiving Station (NRS) occupied the central and eastern portions of Poplar Point. Currently, NACE headquarters, the U.S. Park Police (USPP) Anacostia Operations Facility (AOF), and the USPP Aviation Unit facilities occupy the portion of the Poplar Point property formerly occupied by the NRS. The METRO Green line runs underground through the western end of the former NRS parcel.

In 2006, Congress enacted legislation (Public Law 109-396, commonly referred to as the DC Lands Act) directing the United States to transfer the NPS property at Poplar Point to the District of Columbia (District), but the transfer is not yet complete. The former greenhouse and nursery areas are unused and have revegetated.

Poplar Point Environmental Investigations

Since the early 1990s, a number of environmental investigations have been performed at the Poplar Point Site. Most of these investigations focused on the southwestern portion of the Site, in the areas formerly operated as nurseries and greenhouses. Those investigations identified contamination consisting of metals, pesticides, semi-volatile organic compounds (SVOCs), volatile organic compounds (VOCs), petroleum hydrocarbons, and polychlorinated biphenyls (PCBs) in Site soils. In addition to the environmental investigations, abandoned drums and inactive underground and above ground storage tanks were removed from the Site.

In September 2008, NPS and the District entered into a Settlement Agreement under which the District agreed to conduct a Remedial Investigation (RI) and Feasibility Study (FS) in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) of the entire Poplar Point Site under the oversight of NPS. The RI/FS will be completed in accordance with CERCLA’s associated regulations provided in the National Oil and Hazardous Substances Pollution Contingency Plan or NCP. The RI will characterize the environmental conditions of the Site, and will include assessments of the ecological and human health risks posed by hazardous substances present at the Site. The FS will present a range of cleanup alternatives and evaluate those alternatives using the criteria prescribed in the NCP. Following completion of the RI and FS, a Proposed Plan identifying the preferred cleanup alternative will be issued for public review and comment.

Between 2018 and 2020, the District, with NPS oversight, completed the first phase of RI field activities. These activities included collecting environmental samples to determine the nature and extent of contamination at the Site. The District and NPS analyzed the results of the first phase of the RI and identified data gaps. Additional field investigations were completed between 2022 and 2023 to collect the data necessary to fill the data gaps. The District and NPS are preparing a RI Report that will include an assessment of risk posed by hazardous substances present on the Site to human health and ecological receptors. In accordance with the CERCLA response framework outlined in the NCP, the District will prepare a FS after the RI Report is finalized. The RI/FS is currently expected to be completed by late 2025. Once the RI/FS is completed a Proposed Plan will be prepared to describe the plan to cleanup contamination that has been determined to pose an unacceptable risk to human health or the environment.

 

Poplar Point Site Documents

The National Park Service maintains a record of all Site-related environmental investigations in the Site’s Administrative Record (AR). The AR contains the documents that will form the basis for selecting a cleanup remedy and is updated periodically throughout the project. The AR index lists all documents currently included in the Site's Administrative Record. The AR documents are available at Anacostia Neighborhood Library for review. Electronic copies of the administrative record may also be requested by contacting National Capital Parks — East Superintendent's Office.
