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.

History

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.
