Ah Environmental Consultants, LLC

Ah Environmental Consultants, LLC (doing business as Ah Environmental Consultants Inc.), a small business subchapter S corporation based in Newport News, Virginia, delivers environmental and engineering consulting services to Department of Defense and federal water infrastructure agencies as a prime contractor on full-and-open delivery orders and indefinite delivery vehicles, with no subcontractor footprint and no set-aside posture across its prime portfolio.

The company specializes in concrete environmental and water infrastructure services: drinking water system sanitary surveys, stormwater pollution prevention plan (SWPPP) development and updates, illicit discharge surveys, spill prevention control and countermeasure (SPCC) planning, wastewater infrastructure assessment, hydrology investigation and modeling, cross-connection and backflow prevention surveys, facility response planning, PFAS and water quality sampling, and hazardous material remediation across Department of Defense installations and federal water systems. Representative work includes a $966,605 firm fixed-price delivery order (March 2026) from Naval Facilities Engineering Command for water quality oversight council drinking water system sanitary surveys at overseas installations; a $820,996 order (January 2025) for Atlantic Area of Responsibility sanitary surveys; a $783,120.64 order (March 2026) from the U.S. Army Corps of Engineers for architect-engineer services including project management, inspection oversight, and design at the Washington Aqueduct; a $774,176 order (May 2025) for wastewater treatment capital improvement at Camp Lejeune; and a $602,511 order (September 2025) for hydrology investigation and modeling at Naval Air Station Pensacola.

Customer concentration is extreme and singular: Naval Facilities Engineering Command dominates the portfolio with 210 awards carrying $124.7 million combined potential value (55% of all dollars), followed distantly by the U.S. Army Corps of Engineers Washington Aqueduct (3 awards, $37.2 million), the United States Marine Corps (95 awards, $15.1 million), and Navy Installations Command (105 awards, $11.2 million). The top five customers account for 86% of combined potential value. NAVFAC's concentration reflects a single $60 million indefinite delivery contract for safe drinking water and clean water services awarded January 14, 2025, and running through January 13, 2030, which has already generated more than ninety task orders across naval and Marine Corps installations domestically and at overseas locations (Japan, Korea, Spain, Italy, Greece, Romania, British Indian Ocean Territory). A second major vehicle is a $35 million multiple-award architect-engineer IDIQ with the Army Corps of Engineers Baltimore District for Washington Aqueduct services, set aside for total small business and running through February 7, 2028. The company sits on five named parent vehicles with 309 combined task orders.

Activity has grown unevenly: nine awards in 2022, thirty-one in 2023, fourteen in 2024, thirty-two in 2025, and twenty-seven in the first seven months of 2026. Thirty-five awards (combined potential value $8.6 million) reach ultimate completion inside the next twenty-four months and therefore face recompete. The vendor holds 737 total prime awards across 34 federal customer agencies with combined potential value of $225.3 million and combined dollars obligated at $99.3 million (44% of potential value).

Ah Environmental Consultants is a wholly owned child of True Environmental Holdings LLC, a New York-based partnership or limited liability partnership. The corporate structure carries no visible subsidiary differentiation in the source data; the parent holding company appears to house the operating subsidiary without separate capability branding. The vendor's NAICS concentration skews toward engineering services (349 awards) and environmental consulting services (211 awards), with architectural services (61 awards) and remediation services (27 awards) comprising the remainder. PSC codes track the same pattern: architect and engineering general services dominate (298 awards), followed by environmental services codes (83 awards) and special studies/analysis environmental assessments (22 awards). No visible set-aside activity appears in the prime awards; Ah Environmental competes on capabilities in open procurements and holds two small-business-set-aside IDVs with NAVFAC and the Army Corps of Engineers, yet individual task orders under those vehicles typically carry no set-aside designation, indicating competitive task-order competition within the reserved vehicles or sole-source ordering authority.
