Spring Valley, a predominantly residential area of Washington, DC, is located on a former World War I chemical weapons development and testing site.

Spring Valley Cleanup

Washington, DC

Spring Valley is the site of a former World War I chemical weapons development and testing site where chemicals such as arsenic, mustard, and Lewisitte (among some 150 other chemicals) have been discovered.

Since 2002, Environmental Stewardship Concepts has been a technical advisor to the Restoration Advisory Board for the cleanup of the chemical weapons development and testing in this residential area of Washington, DC. Cleanup activities are being carried out under the FUDS program of the Department of Defense. The main human health risks are from arsenic found in the soil as well as buried chemical munitions and containers.

In May 2011, the Draft Final versions of the Remedial Investigation Report for 4825 Glenbrook Road and the Site-Specific Investigation Report for 4835 Glenbrook Road have been released to ESC and other Spring Valley partners. Partner comments on the drafts will be considered and addressed at the end of the comment period.

The Draft Final Site-Wide Feasibility Study was released to ESC and other Spring Valley partners in late 2015, and the Draft Final Site-Wide Groundwater Remedial Investigation report is anticipated to be released soon.
