About the company
Princeton Hydro LLC, a Trenton, New Jersey–based environmental and engineering consulting firm, operates as a prime contractor delivering geotechnical investigations, water resources engineering, coastal ecosystem restoration design, and NEPA assessment services to the U.S. Army Corps of Engineers and the Department of the Interior. The firm competes predominantly full-and-open across its prime footprint, with recent awards split between Total Small Business set-asides and unrestricted competitions; it maintains a named subsidiary, Princeton Hydro – Baird Joint Venture LLC, a self-certified small disadvantaged business.
Customer concentration is heavily skewed toward USACE. The top five customer agencies account for 59% of awards by count but 97% of combined potential value. The Department of the Army Corps of Engineers dominates across multiple districts: the New York District alone anchors 29 awards worth $44.6 million; the agency proper accounts for 10 awards worth $62 million (including parent IDVs); Baltimore District contributes 9 awards worth $37.1 million; and Philadelphia District rounds out the Corps footprint with 9 awards worth $7.2 million. The Department of the Interior Fish and Wildlife Service Region 9 Headquarters holds one award — a $25 million multiple-award indefinite-delivery contract for geotechnical engineering services with a Total Small Business set-aside through April 2027, placing it fourth by potential value despite a single award count. Recent named work includes a $4.226 million delivery order with USACE Baltimore for the Atkisson Dam Removal project (geotechnical investigations, subsurface exploration, environmental assessment, and construction oversight, completion October 2026); a $6.883 million delivery order with USACE New York for design services through December 2026; and a $1.41 million Commercial Solutions Opening competitive contract with the Army Corps of Engineers Engineer Research and Development Center for evaluating innovative treatment strategies to control harmful algal blooms in Lake Hopatcong, New Jersey (completion September 2026).
Princeton Hydro's vehicle position is anchored in USACE indefinite-delivery contracts and blanket purchase agreements. The firm holds or sits on five named parent vehicles: an indefinite-delivery contract (W912DS14D0001) with 21 task orders worth $12.9 million combined potential value; an indefinite-delivery contract (W912DR20D0015) with 8 task orders worth $13.7 million; an indefinite-delivery contract (W912DS19D0003) with 12 task orders worth $10.3 million; an indefinite-delivery contract (W912BU21D0003) with 12 task orders worth $4.2 million; and a blanket purchase agreement (INR06PB810231) with 22 task orders. The firm also holds a $3.406 million other transaction IDV with USACE (awarded September 2025) for evaluating innovative habitat control measures in Presque Isle Bay, Lake Erie, Pennsylvania, and a $250,000 single-award BPA with USACE New England District for materials testing through September 2025.
Activity has declined from eight awards in 2022 to three in 2026 year to date. Six awards carrying combined potential value of $14 million reach ultimate completion within the next twenty-four months, creating recompete exposure for the vendor and opportunity for competitors. The Service Contract Inventory dataset captures minimal activity — SCI-reportable invoiced revenue totaled $289 thousand in FY2024 alone (FY2023 and FY2025 show zero reported invoicing), with 0.3 FTEs reported in FY2024. This sparse SCI footprint reflects that most of Princeton Hydro's federal work is structured as fixed-price delivery orders, which typically fall below the $150,000 annual invoicing threshold that triggers SCI reporting, and does not represent the vendor's total federal services revenue. On the single SCI-reportable contract (the $860,643 Fish and Wildlife Service Cole's Mill Dam feasibility and design award), government-paid rates ran $189.62 per hour, with subcontractors performing 60 percent of contractor hours across four named subcontractors.
Princeton Hydro operates as a prime on 99% of recent awards and rarely subcontracts to other federal primes. The firm performs work nationwide with administrative offices in Trenton and operational footprint concentrated in the Mid-Atlantic region — New Jersey, Maryland, Delaware, and Pennsylvania — supporting USACE coastal, navigation, and ecosystem restoration missions, though recent awards extend to Pennsylvania lake management (Presque Isle Bay, Lake Erie) and demonstrate capability across diverse geotechnical and environmental assessment scopes.
