Spring Valley Overview

The Spring Valley Formerly Used Defense Site (FUDS) consists of approximately 660 acres in the northwest section of Washington, D.C. During the World War I‐era, the site was known as the American University Experiment Station, and was used by the U.S. government for research and testing of chemical agents, equipment, and munitions. Today, the site encompasses approximately 1,600 private properties, including several embassies and foreign properties, as well as the American University and Wesley Seminary.

Community Participation



The U.S. Army Corps of Engineers, Baltimore District has the lead responsibility for investigation and cleanup actions at the Spring Valley FUDS and has entered into a formal partnering process with the U.S. Environmental Protection Agency and the Washington, D.C. District Department of the Environment. The three organizations, referred to as the partners, have agreed to prioritize the project work by risk, addressing the highest risks first. The Corps investigation includes the identification and removal of arsenic‐contaminated soil, a groundwater investigation, and the search for additional munitions, both in burial pits and isolated items on residential properties.

Spring Valley Formerly Used Defense Site - Notification of Five-Year Review

This Public Notice is to inform the community of the U.S. Army Corps of Engineers’ (USACE) intent to conduct the 2023 Five-Year Review (FYR) for the Spring Valley Formerly Used Defense Site (SVFUDS), located in the northwest section of Washington, D.C. Specifically, the FYR will evaluate the Munitions Response Sites (MRS) Burial Pits/Field Test Areas. The American University (AU) campus comprises a portion of the MRS along with the Dalecarlia Woods area located on the western edge of the SVFUDS, which is zoned for Federal or public use. It should be noted that the property located at 4825 Glenbrook Road, as well as the surface water and groundwater at that site, are not a part of this FYR.

The purpose of the FYR is to determine if the remedy selected in the Decision Document (DD) for the above listed MRS is, and will continue to be, protective of human health and the environment.  The Army is required to evaluate the protectiveness of these remedies at least every five years in order to ensure selected remedies continue to meet acceptance standards for hazardous substances, pollutants or contaminants remaining in the soil.

Work Previously Completed: The Remedial Investigation (RI) Report, prepared by USACE in 2015, determined that unacceptable risks posed by soil contamination and unacceptable explosive hazards posed by military munitions that may, upon recovery and evaluation by qualified personnel, be determined to be Munitions and Explosives of Concern (MEC), specifically unexploded ordnance (UXO) and discarded military munitions (DMM), potentially remain within the SVFUDS. Because of this potential risk, the DD, signed 15 June 2017, called for the Excavation and Off-site Disposal of contaminated soil to address unacceptable risk, which was completed in 2022. Additionally, to address the unacceptable MEC hazards, the selected remedy is Investigation and Removal of MEC and Institutional Control (IC) Implementation of 3Rs Explosives Safety Education. Soil is the only medium affected. The MEC removal work is on-going and the ICs remain in place.

Contact Information:  Scheduled date of completion of this 2023 SVFUDS Burial Pits/Field Test Areas FYR anticipated to be 31 December 2023.  If you have any questions or comments about the FYR, please contact the U. S. Army Corps of Engineers, 2 Hopkins Plaza, Baltimore, MD  21201.  USACE welcomes your comments and questions.  The point of contact for further information is Project Manager Dan Noble, U.S. Army Corps of Engineers, Baltimore District at (410) 962-6782 or
