Since 2005, the U.S. Army has invested over a billion dollars in the construction of research facilities, as well as Army Reserve and National Guard training centers, in the Edgewood Area of APG. These state-of-the-art research facilities are threatened by 63 vacated neighboring buildings where chemical, biological, radiological, nuclear, and explosive materials were used and tested. These materials could remain in the facilities as well as in the soil and groundwater beneath them. Contaminants could include CAs and their breakdown products, biological agents, and white phosphorous (WP). For remediation purposes, the facilities have been divided into two groups.
In 2019, HGL was awarded a contract to characterize, demolish, and remediate the Group 1 Facilities (247,754 square feet), which represent the highest risk structures for residual contamination. Group 1 comprises 18 buildings and 1 slab where the building has already been demolished. HGL has completed demolition of these structures and has properly disposed of all generated waste including 58,420 tons of demolition waste; 1,510 tons of asbestos-containing material; 54 tons of WP-contaminated media; and 507,400 gallons of WP-contaminated water, all without a single lost-time incident. In 2021, HGL was awarded a competitive contract to conduct the same activities for the Group 2 Facilities (287,814 square feet) consisting of 8 buildings and 23 slabs and anticipates completing the project in 2026.
