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
- Following the holiday break, crews returned to the Glenbrook project area on January 6th, to complete the final effort to remediate and restore the site. The site operations team made great progress on removing the flowable fill and I-beams from the soldier piles in the south corner of the property near Glenbrook Road. This effort involved using a mechanical jack hammer and hand held construction equipment. These soldier piles were installed several years ago by the Army Corps to temporarily replace a retaining wall that we needed to remove, as well as support the embankment of soil along the shared property line during our extensive excavation efforts at the project area. Following the removal of the soldier piles at this corner of the property, clean soil will be brought in and compacted, to restore the appropriate elevation levels of the land.
- In Addition, the team began preparing for removal of the remaining two small Hazard and Toxic Waste contaminated soil removal areas; one at the previously excavated Area 4, and the other along the wall at the shared property line with 4835 Glenbrook Road. That excavation effort is tentatively planned to begin during the week of February 24th, and will take a few weeks to complete.
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 PSB; and the final geophysical surveys for potential WWI munitions at 92 residential properties and 13 city/federal properties.
- At AU’s former PSB, the crews completed benching the upslope soils, staged both the soil screening and decontamination stations, and removed the former PSB foundation. Additionally, they have started excavating the soil beneath the former PSB and continue to encounter laboratory grade glassware. As the glassware is identified, it is secured and sent for analysis. The soil excavation work is anticipated to take 2-3 months to complete.
- Remedial Action fieldwork efforts continued at several residential properties and city/federal properties in January. The geophysical survey team remobilized and conducted surveys at multiple properties. Additional efforts included working to finalize more arborist landscape appraisals and plant removal plans with homeowners.
- The regulatory Partners (DOEE and EPA) reviewed the initial sampling results and agreed to conduct additional groundwater data collection in Spring 2020. After this confirmation sampling is completed, the Army Corps and Partners will discuss the results and determine the path forward for the final groundwater approach.
