TRC Environmental Corporation

TRC Environmental Corporation Windsor Office Division, doing business as TRC Environmental Corp, is a global environmental consulting firm that serves as a prime contractor (98% of recent awards) for federal agencies on Superfund remediation, groundwater monitoring, and environmental investigation and design services across civilian agencies, predominantly the Federal Aviation Administration.

TRC Environmental Corp is a subsidiary of TRC Companies, Inc., a for-profit Connecticut-based corporation headquartered at 21 Griffin Road North in Windsor, Connecticut. The corporate structure includes named subsidiaries TRC Engineers Inc. The vendor competes on full-and-open procurements with no set-aside designations across its federal footprint.

Customer concentration is extreme and FAA-dependent. The top five funding agencies account for 69% of awards: the Department of Transportation Federal Aviation Administration (FAA) Headquarters leads with 137 awards and $59.3 million in combined potential value, followed by the FAA Technical Center with 43 awards and $15.9 million, the Department of Agriculture Forest Service R8-Southern Region with 13 awards and $21.3 million, the Environmental Protection Agency with 22 awards combined, and the Department of the Navy with 18 awards. The dollar ranking diverges from volume — USDA Forest Service ranks second by potential value despite lower award count, driven by the $50 million Land Management Integrated Resources (LMIR) multiple-award Blanket Purchase Agreement that TRC holds. On potential-value basis, FAA Headquarters, USDA Forest Service, and FAA Technical Center represent 62% of total combined potential value across the entire portfolio.

TRC's capability portfolio centers on environmental site investigation, Superfund cleanup design and implementation, groundwater modeling and sampling, biota and natural attenuation monitoring, PFAS and tetrachloroethylene (PCE) characterization and remediation, remedial design and pre-design studies, air quality filter acceptance testing and distribution, and archaeological assessment. Representative prime work includes a $400.9 million delivery order from FAA for Year 2 post-injection planning and groundwater sampling at Area 20A (awarded Mar 13, 2024); a $765.5 million delivery order for pre-design study, permitting, and remedial design of a Permeable Adsorptive Barrier at FAA Area B (awarded May 11, 2022); a $1.3 million delivery order from FAA for pre-design study and engineering evaluation at Area 41 (awarded Apr 12, 2022); a $575.6 million delivery order from EPA for predesign study and remedial design at Superfund Area of Concern 41 (awarded Sep 1, 2023); a $1.05 million purchase order from EPA Office of Air and Radiation for procurement, testing, and distribution of high-purity air sampling filters through Aug 31, 2030 (awarded Sep 11, 2025); and a $289.9 million BPA call from USDA Forest Service for archaeological assessment in Pisgah Forest, North Carolina (awarded Aug 11, 2022).

TRC holds a seat on four primary federal contract vehicles. The FAA Indefinite Delivery Contract DTFACT17D00008 carries 133 task orders worth $21.5 million in combined potential value. The GSA Multiple Award Schedule has generated 42 task orders valued at $20.4 million. The FAA Indefinite Delivery Contract DTFACT14D00003 supports 29 task orders totaling $5.2 million. The FAA Indefinite Delivery Contract DTFACT09D00004 carries 28 task orders worth $11.2 million. The $50 million USDA Forest Service Land Management Integrated Resources BPA, awarded Jul 3, 2024, with ultimate completion Mar 6, 2033, serves as a multi-agency vehicle enabling TRC to issue task orders across any federal customer for environmental consulting, natural resources restoration, engineering, and project management.

Award volume has remained moderate and relatively flat over the past five years — 11 awards in 2022, 18 in 2023, 20 in 2024, 16 in 2025, and 4 year-to-date in 2026 (four months elapsed). Eleven awards with combined potential value of $2.2 million face ultimate completion inside the next twenty-four months and therefore present recompete exposure for TRC.

TRC operates predominantly as a prime contractor on direct federal work; across the recent sub-award footprint, TRC subcontracts to EA Engineering, Science, and Technology, Inc., PBC on PFAS research laboratory and field study support and drinking water state revolving fund technical assistance work, and to Burns & McDonnell Engineering Company, Inc. on hazardous building materials sampling and environmental protection planning at Kirtland Air Force Base. TRC also appears as a named subcontractor to National Academy of Sciences on a transportation resilience practices implementation grant and to San Joaquin Valley Unified Air Pollution Control District on a pre-NEPA air quality grant.

Service Contract Inventory data shows minimal SCI-reportable invoiced revenue; across the three fiscal years in the source (FY2022–FY2024), SCI records zero invoiced amount at the prime level and reflect only 0.2 FTEs in FY2022 with near-zero staffing in subsequent years. SCI captures only service contracts above the $150,000 threshold and excludes goods, products, and classified work; these figures do not represent TRC's full federal revenue or workforce and reflect the fact that most TRC federal work flows through fixed-price delivery orders and purchase orders that may not trigger SCI reporting thresholds or that are goods-dominant or classified.
