The site is bounded on the west by Federal property west of Dalecarlia Pkwy; on the south by Loughboro Road; on the east by Nebraska Avenue, a small portion of Wisconsin Avenue and 42nd Street to just short of Albemarle Street; and on the north by short sections of Ashton Place and Yuma Street, Windom Place, Van Ness and Massachusetts Avenue. The site includes new residential developments surrounded by older residential neighborhoods, including Spring Valley, Spring Valley West, Fort Gaines and a section of American University Park.In December 1918, orders were given to discontinue the use of Camps Leach and American University "with the least practicable delay." The supplies and equipment were to be disposed of, and all salvageable property was to be sold at auction. None of the buildings on American University were to be salvaged or disposed of at that time. All temporary buildings which had become dangerous by reason of gas saturation were destroyed by burning to the ground by the Washington, D.C. Fire Department.

The Government further agreed to vacate the premises and restore the remaining property to its original condition. The Government was granted continued occupancy until June 1920, and the University agreed to "waive and release the Government from any and all claims and obligations, whether for damages, rental, or otherwise arising out of the occupancy or use by the Government ... except such claims as (Source: U.S. Army Corps of Engineers) « see less

Update (Dec. 5, 2017): We have changed the source of the installation cost data after being notified by the Department of Defense that they erroneously reported their own cost figures on the DERP website. We are now displaying the costs the department says are the most accurate available, from the Pentagon’s DERP database that we received in a FOIA request.
Note: The risk level of a site refers to a relative risk assessment made by the DOD to prioritize the cleanup of sites.
Data: All data comes from the Defense Environmental Restoration Program and the U.S. Army Corps of Engineers, and will be released soon at the ProPublica Data Store. Read our methodology »
