About the company
Citadel Environmental Services, Inc., doing business as Citadel Environmental, is an environmental consulting and industrial hygiene services provider that operates predominantly as a prime contractor (97% of awards) for federal agencies, with a specialized focus on Veterans Affairs facilities and federal buildings. Based in Glendale, California, the company delivers environmental remediation, industrial hygiene assessments, methane monitoring, waterproofing engineering, and hazardous waste management services across 59 federal awards spanning more than two decades.
Customer concentration is extreme and stable. The Department of Veterans Affairs Veterans Health Administration Veterans Integrated Service Network 22 accounts for 45 awards (76% of the total prime footprint) and $5.4 million in combined potential value — 72% of the vendor's total addressable federal market. The General Services Administration Federal Acquisition Service anchors the second-largest dollar magnitude ($2 million on a single award), with GSA's Public Buildings Service Region 9 and a standalone DVA customer rounding out the active set. This concentration reflects Citadel's primary mission as an environmental service provider embedded in VA real estate and facilities operations. The company sits on two GSA vehicles: the Multiple Award Schedule (39 task orders, $5.1 million combined potential value) and the Professional Services Schedule (15 task orders, $2.1 million combined potential value).
Work characterization is grounded in environmental compliance and facility protection. Top named NAICS categories are Environmental Consulting Services (45 awards), Engineering Services (2 awards), Testing Laboratories and Services (1 award), and Hazardous Waste Treatment and Disposal (1 award). Recent representative work includes a $19,940 purchase order from Veterans Integrated Service Network 22 for methane monitoring and quarterly reporting at a California VA facility (awarded September 8, 2026, concluding October 31, 2026). The company also subcontracts to Amentum Technology, Inc. on Schwartz Central Plaza waterproofing and engineering services in San Diego, including a modification dated October 9, 2024 for fixed-asset funding updates and accounting corrections on that same facility project.
Award activity is sparse and episodic: one award in 2017, one in 2023, one in 2024, and one in 2026, with a combined potential value of $7.5 million and obligated dollars reaching $3.1 million (42% of potential value). Only one award faces completion within the next twenty-four months ($20 thousand potential value), indicating minimal near-term recompete exposure. Citadel operates a subsidiary, Aurora Industrial Hygiene, certified as a small disadvantaged business organized as a Subchapter S corporation; however, recent prime awards are not set-aside designated. The vendor's federal footprint centers on scheduled maintenance, environmental compliance, and facilities engineering at VA installations, with limited exposure to other federal customers or full-and-open competitive work.
