About The Source Group, Inc.
The Source Group, Inc. (doing business as The Source Group Inc., Apex Group LLC, and SGI Environmental) is an environmental and engineering consulting firm providing project planning, management, environmental remediation, facilities maintenance, utilities infrastructure support, and energy sustainability services to federal agencies as a prime contractor, with 100% of its federal awards as prime work and no set-asides used across its footprint. Headquartered in Pleasant Hill, California, and registered in SAM.gov since 2002, The Source Group is a for-profit corporate entity that is a subsidiary of Apex Companies, LLC (a Rockville, Maryland-based LLC parent). The company operates under NAICS codes concentrated in remediation services (156 of 158 awards) and environmental consulting, with primary PSC coding in environmental systems protection and oil spill response.
Customer concentration is extreme and represents recompete risk. The Defense Logistics Agency Energy funds 154 of 158 total awards (99% of award count), representing $1.19 billion in combined potential value against a total portfolio of $1.2 billion. The Department of the Navy and the Department of the Air Force Materiel Command account for one award each, totaling $57 thousand. This DLA Energy lock creates both competitive advantage and cliff exposure: The Source Group has obligated $298 million (25% of potential value) to date and holds five significant IDIQs with DLA Energy. The two largest vehicles, Indefinite Delivery Contracts SP060014D5411 and SPE60320D5010, anchor the portfolio with 66 and 36 task orders respectively and combined potential value of $136.5 million. Two additional single-award IDIQs awarded in August and September 2025 for environmental remediation and facility maintenance at Defense Fuel Support Points in California carry combined ceiling values of $66.1 million and support the Facilities Energy and Sustainability program through 2029 and 2030.
Representative recent work includes a $2.28 million firm fixed-price delivery order for project planning and management under the Facilities Energy and Sustainability program (ultimate completion October 2026), a $2.22 million time-and-materials delivery order for utilities support services in San Diego, California (ultimate completion August 2029), a $1.5 million delivery order for utilities support also in San Pedro, California (ultimate completion September 2029), and a $9.4 million firm fixed-price delivery order for project planning and management (ultimate completion September 2025). Activity declined from 13 awards in 2023 to 8 in 2024, recovered to 10 in 2025, with only one award recorded in 2026 to date. Three awards face ultimate completion within the next twenty-four months, carrying combined potential value of $5.4 million and representing limited near-term recompete exposure; however, the five largest IDIQ vehicles collectively carry multi-year scope running through 2030, anchoring sustained task-order pipeline dependent on DLA Energy's continued funding of Facilities Energy and Sustainability priorities.
The Source Group performs as prime contractor across all awards without major subcontractors, with place of performance primarily at Fort Belvoir, Virginia; Pleasant Hill and San Pedro, California; and San Diego, California. The corporate structure shows The Source Group as a child entity of Apex Companies, LLC, with the parent holding its own federal contract vehicle position. This DLA Energy concentration—154 awards under a single customer with no sub-award diversification—creates both deep customer entrenchment and vulnerability to agency budget fluctuation or competing prime selections on IDIQ recompetes.
