4825 Glenbrook Road Weekly Update, November 20

The small crane and related equipment arrived early Monday morning, without incident. Local Police and our team assisted with any traffic concerns, and all efforts impacting road traffic were completed before noon. The crane will be used to set up Tent 3 over the next few weeks, and any additional impact to traffic will be minimal. Also this week, the crews started to move the ballast blocks (see photo) that balance and support the tent frame, and performed other site preparations such as turning off the water. On Thursday we started unlacing the fabric between the tent sections. 

We will not be sending out a neighborhood update next week. The Thanksgiving break will start on Wednesday, November 25th, which allows our expert team, many who live out of state, to travel and be with their families. Work will resume on Monday, November 30th . After the Thanksgiving holiday, we will complete our tent disassembly process, and starting the week of December 7th, we anticipate using the crane to begin moving the tent sections into their new location. Once the tent frames are in place we will start to build-out Tent 3, and prepare the site for the equipment to support high probability operations in early 2016.

Reminder: The site will be secured during the holiday breaks. The Christmas break will be from December 23rd to January 4th. Approximately 30 days prior to the start of the next phase, we will begin testing the Shelter-in-Place alert system and provide any necessary re-training for the residents within the Shelter-in-Place zone. We will notify everyone prior to reinstating the Shelter-in-Place program, and also when we have a firm date for the start of the next phase of high probability operations.

Project Overview

The project site is a residential property located at 4825 Glenbrook Road N.W. within the Spring Valley Formerly Used Defense Site in Northwest Washington, D.C. During the World War I era, the property was part of a larger area known as the American University Experiment Station (AUES), where the U.S. government researched and tested chemical agents, equipment and munitions. AUES related waste, including more than 500 munition items, 400 pounds of laboratory glassware and 100 tons of contaminated soil, have been recovered and safely removed from the property during investigations from 2000-2002 and then again from 2007-2010. In August 2010, several agencies within the Department of Defense as well as the regulatory partners, the U.S. Environmental Protection Agency and District Department of the Environment, made the decision to separate the 4825 Glenbrook Road property from the Spring Valley neighborhood site to expedite the cleanup process.

After thorough reviews and a public comment period, the Corps of Engineers, with concurrence from the partners and American University (property owner), selected the alternative to remove the house, cleanup, and restore the property to residential standards, providing for unrestricted future use of the property. This approach is the most effective and protective of human health and the environment. 

Cleanup Implementation

Crews removed the house (Nov. 29 - 30, 2012) systematically from top to bottom using an excavator. After the demolition, crews began preparing the site for the high probability operations. Historical and field data indicate the high probability areas of the property have a greater likelihood of containing AUES debris and/or glassware items.

Site preparation included low probability test pitting in several areas in the backyard, utility relocation, general site preparations, and installation of the engineering controls needed to safely perform the high probability work. The engineering controls include an Engineering Control Structure (a 60’x80’x27’ tent) that fully encloses the high probability excavation areas,a chemical agent filtration system that will filter the air leaving the control structure, and a continuous air monitoring system. All of the materials removed during the high probability phase will be safely disposed.

Additionally, the Corps of Engineers has developed a Shelter-in-Place program as an added layer of protection to the public.  

High probability operations began Sept. 23, 2013 and will wrap-up in winter 2016/2017, depending on the types and amounts of debris encountered.  The goal is to completely remove any remaining AUES debris and restore the property to residential standards by summer 2017.

Information Repository

The Information Repository is located at the Tenley-Friendship Branch Library, 4450 Wisconsin Ave. N.W., Washington, D.C.

Hard copies and digital records of key project documents can be found upstairs in the Reference Section.  The document collection includes a variety of materials created since the start of the project, 20 years ago. Check with the reference librarian to direct you to our shelves of materials.

Also, on your next visit to the library, ask at the Reference Desk for the Spring Valley FUDS large binder, which has a table of contents and almost a hundred disks that contain years of digital records available for research and review. These disks must be checked out from the librarian and are only available for use on the library’s public computers during your visit.  If there is a piece of information you cannot locate in the library, please contact the Community Outreach Team at 410-962-0157.
