About the company
Tetra TECH EC, Inc., a subsidiary of publicly held Tetra Tech, Inc., delivers environmental remediation and site restoration services to the Department of the Navy and Naval Facilities Engineering Command as a prime contractor on long-term federal remediation vehicles, with 98% of recent awards anchored to Navy and Marine Corps customers.
Tetra TECH EC operates as a for-profit corporate entity headquartered in San Diego, California, and competes predominantly in full-and-open federal procurement rather than set-aside categories. The vendor's capability footprint centers on environmental remediation, groundwater sampling, munitions and explosives of concern removal, site closure and restoration, landfill inspection, and associated surveying and engineering services — work grounded in BRAC legacy sites, military installations, and other federal property requiring environmental remediation and facility decommissioning. NAICS concentration runs to 541360 (Remediation Services), with secondary work in geophysical surveying and mapping; PSC concentration sits with environmental systems protection and environmental remediation codes.
Customer concentration is severe and immobile. The Department of the Navy Naval Facilities Engineering Command accounts for 175 awards — 90% of all awards in the portfolio — carrying combined potential value of $1.37 billion, or 99% of combined portfolio value. The United States Marine Corps, the Department of the Navy Installations Command, and NASA Langley Research Center together account for the remaining 7 awards and less than $9 million in combined potential value. This Navy-to-total ratio is characteristic across the award history.
Tetra TECH EC's vehicle footprint anchors to five Navy IDIQs. The largest are NAVFAC Nationwide Environmental Remediation 2010-2015 (17 task orders, $157.3 million combined potential value), Indefinite Delivery Contract N6247307D3211 (32 task orders, $99.7 million), and Indefinite Delivery Contract N6247313D4808 (30 task orders, $98.8 million). A fourth Navy vehicle, N6247306D2201, carries 25 task orders and $97.5 million in combined potential value. Recent work includes groundwater sampling and landfill inspection at former Fort Devens, Massachusetts under a Dawson Mcg, Inc. prime contract and munitions removal at Camp Swift, Texas under a Dawson Solutions sub award. Activity has flattened across the past five years — one award each in 2023, 2024, and 2025 — despite the large portfolio base, suggesting task-order drawdown or completion of major recompete cycles. Combined potential value sits at $1.38 billion against $709.8 million in obligated dollars (52% draw rate).
