Hydrogeologic, Inc.

Hydrogeologic, Inc., doing business as Hydrogeologic Inc., is a minority-owned, Asian-Pacific American small business based in Reston, Virginia, that provides comprehensive environmental remediation, site assessment, compliance, and restoration services to federal agencies as a prime contractor on 99% of recent awards. The firm specializes in groundwater and soil treatment, site investigation and characterization, remedial design, long-term environmental monitoring, unexploded ordnance removal, military munitions response program support, and Superfund site cleanup across military installations, NASA facilities, federal properties, and contaminated sites nationwide.

Hydrogeologic operates as a prime contractor on major indefinite delivery vehicles with the Department of the Army Corps of Engineers, the Environmental Protection Agency, NASA, and the Defense Logistics Agency, anchoring its federal portfolio to cost-plus-fixed-fee and firm fixed-price delivery orders. Representative work includes a $93.1 million cost-plus-fixed-fee delivery order from the Army Corps of Engineers (Engineering and Support Center) awarded February 17, 2026, for interim measures at ten sites at Redstone Arsenal, Alabama, under the SEER Chemical, Environmental, and Munitions Contract; a $25.3 million firm fixed-price delivery order from EPA Region 3 awarded September 26, 2024, for remediation environmental services at the Baghurst Drive Superfund site in Pennsylvania; and a $41.3 million cost-plus-fixed-fee delivery order from the Army Corps of Engineers (ENDIST Omaha) awarded July 18, 2025, for construction and environmental remediation at the Bonita Peak Mining District in Colorado. Recent work also includes a $17.9 million firm fixed-price delivery order from NASA Ames Research Center awarded June 16, 2026, for environmental restoration services at Moffett Field, California, under the NASA Environmental Restoration and Compliance Contract.

Customer concentration reflects Hydrogeologic's deep integration with Department of Defense and civilian environmental programs. The top five customer agencies by potential value account for 56% of the combined dollars: the Army Corps of Engineers Engineering Support Center Huntsville ($5.22 billion across 84 awards), the Air Force Materiel Command Installation and Mission Support Center Civil Engineer Center ($3.98 billion across 62 awards), the Army Corps of Engineers Engineering District Omaha ($1.42 billion across 70 awards), EPA Region 3 ($1.39 billion across 20 awards), and the Army Corps of Engineers Engineering District Kansas City ($1.26 billion across 47 awards). By award count, the Air Force Materiel Command Installation and Mission Support Center Installation Contracting Agency leads with 192 awards worth $464.4 million combined potential value, followed by the Department of the Army (94 awards, $100.5 million) and the Army Corps of Engineers Engineering Support Center Huntsville (84 awards, $5.22 billion). The concentration signal differs between the two rankings: while Air Force places the most discrete task orders (typically smaller), the Army Corps of Engineers dominates the dollar footprint through major multi-million-dollar IDIQ vehicles.

Hydrogeologic holds seats on major federal environmental vehicles. The EPA Remedial Acquisition Framework: Design and Engineering Services (DES) has generated 69 task orders totaling $195.5 million. The Army Corps of Engineers' $1.136 billion SEER Chemical, Environmental, and Munitions Contract anchors substantial work, with task orders ranging from a few million to over $49 million. Hydrogeologic also holds a $375 million NASA Environmental Restoration and Compliance Contract (NERCC) as a multiple-awardee under which Kennedy Space Center, Stennis Space Center, Langley Research Center, Goddard Space Center, and Wallops Flight Facility have issued delivery orders. The firm is positioned on an $800 million Aqueous Film Forming Foam MATOC vehicle with the Army Corps of Engineers for PFAS and AFFF support services; a $960 million Ordnance and Explosives Environmental Remediation contract (EMR2); multiple EPA Remedial Acquisition Framework master contracts for both Design and Engineering Services and Remediation Environmental Services; and small business set-aside vehicles such as a $245 million HTRW PRAC from ENDIST Kansas City, a $98 million environmental remediation contract from the Army Corps of Engineers, and a $88.125 million pre-placed remedial action contract for Mississippi Valley Division and EPA Regions 5 and 7. Across its portfolio, Hydrogeologic's approximate collective IDIQ value is $4.9 billion.

Activity has remained steady and robust over recent years. Award counts per year show 28 awards in 2022, 39 in 2023, 44 in 2024, 42 in 2025, and 9 awards year-to-date in 2026 (based on data through mid-June). Within the next twenty-four months, 74 awards with combined potential value of $381.8 million are scheduled for ultimate completion, representing significant recompete exposure across EPA Superfund vehicles, Army Corps of Engineers environmental programs, and Air Force installation environmental contracts.

Service Contract Inventory reporting captures a subset of Hydrogeologic's federal service contracts above the $150,000 threshold and shows fiscal-year invoiced amounts of $8.2 million (FY2022), $4.2 million (FY2023), and $24.7 million (FY2024), representing a dramatic spike in FY2024. FTE trajectory reflects volatility: 733 FTEs in FY2022 fell to 36 FTEs in FY2023, then recovered to 43.6 FTEs in FY2024. On federal service contracts captured in SCI, government-paid hourly rates median around $132.89 per hour, with rates ranging from $26.75 per hour at the 10th percentile to $245.72 per hour at the 90th percentile, indicating a diverse labor mix from junior technical support through senior engineering and project management personnel. Across SCI-reportable prime contracts, subcontractors performed approximately 8% of total contractor hours, with 82 distinct named subcontractors identified over the period. This posture indicates Hydrogeologic primarily builds its own delivery teams while engaging subcontractors selectively to fill specialized technical gaps or enhance capacity on large projects.

Hydrogeologic frequently subcontracts to large primes on environmental work outside its prime portfolio. Named sub-award relationships include work under Ch2M Hill, Inc. on MCAS Beaufort RCRA technical support; Noreas Aptim Environmental Remediation JV on source area removal and groundwater treatment operations and maintenance; Consolidated Nuclear Security, LLC on the Y-12 National Security Complex management and operating contract; and ICF Incorporated on EPA OSRTI technical assessment and support. These engagements reflect Hydrogeologic's positioning as a technical specialist capable of performing sub-tier work under environmental remediation primes while simultaneously anchoring its own prime portfolio.

Hydrogeologic competes predominantly under full-and-open competition without set-aside designation across most of its IDIQ vehicles, though the firm holds multiple total small business set-aside vehicles (including the HTRW PRAC, EMR2, and pre-placed remedial action contracts) where it qualifies as a small business. The vendor's minority-owned and Asian-Pacific American ownership designations are featured prominently in government summaries and appear to support competitiveness in small business set-aside competitions while not limiting participation in unrestricted vehicles. Recent awards show no consistent reliance on set-aside set-asides across the prime footprint; the vendor competes effectively on both set-aside and full-and-open vehicles, suggesting competitive capability independent of set-aside status.
