About Amentum Environment & Energy, Inc.

Written by GovTribe AI ·

Amentum Environment & Energy, Inc. N&E Division, a subsidiary of the global infrastructure consulting firm AECOM, operates as a prime contractor delivering environmental remediation, groundwater treatment, site decommissioning, and geospatial support services to civilian federal agencies. The vendor competes on full-and-open contracts without reliance on SBA set-asides, with 98% of recent awards as prime contractor.

The N&E Division's federal footprint centers overwhelmingly on the Federal Aviation Administration, which accounts for the majority of named awards. The vendor holds a single-award indefinite delivery contract with the FAA valued at $101.8 million through June 30, 2031, for Environmental Remediation Support Services (ERSS) at the William J. Hughes Technical Center Superfund site in Atlantic City, New Jersey. Under this vehicle, Amentum has received dozens of delivery orders covering groundwater treatment plant operations and maintenance, geospatial services (GIS/GPS support), National Environmental Data Repository Management, site-wide groundwater sampling and analysis, selective decommissioning of site features, building demolition, carbon treatment system upgrades, and unexploded ordnance escort services. Representative recent ERSS task orders include a $2.77 million delivery order awarded June 25, 2026, for groundwater treatment plant operations and maintenance (Year 6), a $1.42 million award for GIS/GPS support (Year 6), and a $466.6 thousand order for National Environmental Data Repository Management services. The vendor also holds sub-awards on defense and national laboratory programs: Amentum appears as a named subcontractor to Hanford Laboratory Management and Integration LLC on the 222-S Laboratory Complex operations and maintenance contract (multiple task orders awarded through July 2024 for fire protection engineering support, vacuum system upgrades design, and baseline emergency lighting design), to Fluor Marine Propulsion LLC on Naval Nuclear Laboratory and Propulsion Program support work (Seismic and Structural Re-Evaluation and detailed design task orders awarded March 2026), and to Triad National Security LLC on the Los Alamos National Laboratory SCORPIUS Pulse Title III program (task order dated April 21, 2026).

Across the broader vendor portfolio tracked in the source, the N&E Division and its parent operate as prime on 414 awards (98% of total), with the Department of the Navy, Department of the Army, FAA, NASA, and the Office of the Secretary of Defense forming the top five customer agencies by award count. The FAA Technical Center stands as the largest single customer by potential value ($186.2 million across four awards), reflecting the dominant ERSS contract footprint. Activity has remained steady at 9–15 awards per year from 2022 through 2025, with seven awards (combined potential value $16.5 million) reaching ultimate completion within the next twenty-four months and thus facing recompete exposure. Service Contract Inventory data shows minimal SCI-reportable invoicing across the N&E Division and its named subcontractor engagements; reported FTEs appeared only in FY2024 (17.6 FTEs across prime and sub records), indicating that ERSS delivery orders and other work under this division's footprint fall outside the SCI reporting threshold or are performance-based rather than labor-reportable.

The N&E Division sits within AECOM's broader environmental services architecture, which includes 27 named subsidiaries such as Savannah River Remediation LLC, Washington River Protection Solutions LLC, West Valley Environmental Services LLC, and United Cleanup Oak Ridge LLC — each managing federal environmental remediation and site operations work at different federal facilities. Amentum Environment & Energy operates as the civilian environmental services arm of AECOM, competing on remediation, restoration, and infrastructure support contracts that do not require small-business certifications and rely on established prime contractor relationships with civilian agencies.
