Hydrogeologic, Inc.

Hydrogeologic, Inc., doing business as Hydrogeologic Inc., is a minority-owned, Asian-Pacific American small business headquartered in Reston, Virginia, that delivers environmental remediation, site assessment, compliance, and restoration services to federal agencies as a prime contractor on nearly all of its awards. The company operates across a $24.33 billion combined potential value portfolio centered on the Environmental Protection Agency, the U.S. Army Corps of Engineers, and the Department of Defense, competing predominantly in full-and-open procurements rather than set-asides, though set-aside work recurs across remedial action and munitions response vehicles.

Hydrogeologic's concrete capability portfolio anchors on groundwater and soil treatment, site investigation and characterization, remedial design, long-term environmental monitoring, and military munitions response program support, delivered across Superfund sites, military installations, federal facilities, and contaminated properties nationwide. Recent representative work includes a $93.1 million cost-plus-fixed-fee delivery order from the Army Corps of Engineers Engineering and Support Center for interim measures at ten sites at Redstone Arsenal, Alabama (February 2026); a $41.3 million delivery order for construction and environmental remediation at the Bonita Peak Mining District in Colorado under the Preplaced Remedial Action Contract Northwestern Division (July 2025); a $25.3 million EPA Region 3 delivery order for Superfund remediation at the Baghurst Drive site in Pennsylvania (September 2024); and a $17.9 million NASA Ames delivery order for environmental restoration at Moffett Field, California (June 2026). Expert witness services for litigation support round out the portfolio, particularly through Department of Justice engagements.

Customer concentration skews toward Army Corps of Engineers operations. The Engineering Support Center Huntsville leads by potential value at $5.2 billion across 80 awards; the Air Force Civil Engineer Center anchors $3.98 billion across 61 awards; EPA Region 3 represents $1.79 billion across 21 awards; the Engineering District Omaha carries $1.67 billion across 72 awards; and the Kansas City District brings $1.26 billion across 47 awards. These top five customers account for 57% of combined potential value. Hydrogeologic served 91 distinct federal agencies across the award footprint, reflecting broad reach into environmental programs across civilian and defense portfolios.

Hydrogeologic seats on multiple marquee environmental IDIQ vehicles. The company holds a position on the OASIS+ Total Small Business Set-Aside GWAC (GSA Federal Acquisition Service, awarded August 2026, $999.999 billion ceiling through December 2034); the $960 million Environmental and Munitions Response-Restricted Services Support (EMR2) contract with Army Corps Engineering Support Center Huntsville (Total Small Business set-aside, October 2024–April 2035); the $800 million Aqueous Film Forming Foam support contract (multiple award, February 2029); the $375 million NASA Environmental Restoration and Compliance Contract (NERCC, multiple award, January 2029); the $245 million Hazardous, Toxic, and Radioactive Waste contract with ENDIST Kansas City (Total Small Business set-aside, October 2030); the $240 million Northwest Division Environmental Remediation Services contract (unrestricted multiple award, October 2026); and the $98 million Army Corps Environmental Remediation Services contract managed by ENDIST St. Louis (Total Small Business set-aside, May 2030). The EPA Remedial Acquisition Framework: Design and Engineering Services (DES) master contract generated 73 task orders totaling $207.7 million. Recent task order velocity under these vehicles runs at 42 awards in 2025 and 17 awards in 2026 year-to-date, reflecting sustained customer demand. One hundred four awards face ultimate completion inside the next twenty-four months, carrying combined potential value of $533.9 million and representing recompete exposure and opportunity.

The company operates primarily as a prime contractor—99% of awards are primes—and builds significant delivery capability through subcontractor engagement. Across SCI-reportable prime contracts, subcontractors performed an average of 8 percent of total contractor hours, with 128 named subcontractors across the footprint. Named teaming partners include Ch2M Hill Inc., ICF Incorporated, Aptim Federal Services, and Noreas Aptim Environmental Remediation JV. SCI-reported invoiced revenue reached $39.6 million in FY2025 across 76.5 FTEs, reflecting upward trajectory from $24.7 million and 51.3 FTEs in FY2024. Government-paid hourly rates on service contracts span a median of $140.53/hr, with the 10th percentile at $33.74/hr and the 90th percentile at $260.49/hr, indicating a broad labor mix from junior technical staff through senior management and program leadership. The company's GSA Multiple Award Schedule presence carries 31 active labor categories ranging from Junior Engineering Technician at $53.07/hr through Program Manager at $249.76/hr, with no security-cleared roles offered. The vendor's federal services footprint shows growing FTE deployment—from 36 FTEs in FY2023 to 61.5 FTEs in FY2025—supporting increasing task order volume across Army Corps, EPA, and NASA environmental remediation missions. Award activity accelerated year-over-year from 28 awards in 2022 to 44 in 2024, stabilizing around 42 in 2025, demonstrating sustained market presence and customer confidence in delivery across the federal environmental remediation landscape.
