This monthly Spring Valley Formerly Used Defense Site (FUDS) project summary is provided by the U.S. Army Corps of Engineers (USACE), Baltimore District, as part of its ongoing efforts to make information regarding the neighborhood investigation more accessible to community members, elected officials, Restoration Advisory Board members, and other interested stakeholders. Specifically, the monthly update is produced to provide those who follow the project with a current snapshot of regulatory partnering, planning and field activities, and is not designed to provide historical information or an overview of the project. Those individuals interested in broader project information, or who have follow-up questions regarding this update, are invited to contact our Community Outreach Team at 410-962-2210. You may also contact our project regulatory partners, Brian Barone (DOEE) at 202-499-0437 or Steven Hirsh (US EPA) at 215-814-3352.
Glenbrook Road NW
- With the Glenbrook project area near completion, our crew are conducting a variety of tasks pertaining to the final restoration and also preparing to resume the remaining small excavation efforts in Areas 2 and 4 when the cooler fall weather arrives.
- The efforts at the Glenbrook Road project area included preparing respirators and accessories for recertification so they will be ready for the upcoming efforts at Area 2 and 4, a weekly effort of pumping hundreds of gallons of water out of the holding tank for stormwater runoff, fixing the silt fence behind the dress out trailer, conducting grounds and equipment maintenance, and excavating an existing dirt ramp so that surveyors could take elevation measurements.
- The crew at the Federal Property site also focused on site and equipment maintenance, in preparation for resuming the soil removal effort. This included rebuilding the waste load out area.
- The soils sample analysis results for the area associated with the empty glass container recovered in late July were clear for agent and agent breakdown products.
Site-Wide Remedial Action (RA)
- The Remedial Action continued with two main efforts: the investigation of the soils under the foundation of American University’s (AU) former Public Safety Building; and the final geophysical surveys for potential WWI munitions at 92 residential properties and 13 city/federal properties.
- At AU’s former Public Safety Building, the team continued to work with AU and Partners on the basement slab removal plans. The team continued preparing the area by removing landscaping, installing erosion and sediment controls, and moving various utility lines from around the former building’s footprint. The team anticipates the removal operations to begin in September.
- Fieldwork continued at several of the residential properties and city/federal properties this month. These efforts included working to finalize arborist landscape appraisals and plant removal plans with homeowners. Advance geophysical classification surveys and plant removals were also conducted at several properties.
- As a reminder, the formal Dispute Resolution with the regulatory Partners (DOEE and EPA) was suspended to discuss conducting additional groundwater data collection. The Army Corps is moving forward with a new round of groundwater monitoring well samples to obtain more current information. This will enable us to determine if there are any significant changes in the low levels of arsenic and perchlorate concentrations since the last sampling event (4 years ago). In August, the Army Corps began their sampling efforts by redeveloping the wells to remove sediment buildup. We anticipate continuing the sampling effort in September.
Restoration Advisory Board (RAB)
- The next RAB meeting will be held on Tuesday, September 10th at 7 p.m. These meeting are open to the public. Currently, the RAB meets every odd month in the ‘Undercroft’ meeting room at St. David’s Episcopal Church, 5150 Macomb Street NW, D.C.
