About the company
Terri Hennon doing business as Terra Physics, a woman-owned sole proprietorship based in Highland, California, provides geophysical surveying and environmental site assessment support to the Department of the Navy as a subcontractor on federal environmental remediation contracts. Terra Physics operates exclusively in a subcontractor role — all three recent awards are sub-tasks under AECOM Technical Services, Inc. — and does not hold prime contract vehicles or IDVs.
Terra Physics's customer base is entirely concentrated within Naval Facilities Engineering Command. The vendor has delivered three awards since March 2024 (combined $230 thousand obligated), all for Navy environmental remediation work at Pacific installations. Recent sub-task work includes geophysical surveys for PFAS remedial investigation at Naval Base Point Loma, San Diego (May 2026); utility clearance support for tank closure and site assessment planning at Red Hill, Joint Base Pearl Harbor-Hickam, Hawaii (September 2024, under Indefinite Delivery Contract N62742-23-D-1802); and utility clearance for remedial investigation planning at Andersen Air Force Base, Guam's North Ramp Munitions Dump (March 2024, under Indefinite Delivery Contract N62742-17-D-1800). The two parent contracts, both AECOM-held Navy indefinite delivery vehicles, account for all placement activity — two task orders under the 2023 contract and one under the 2017 contract.
Activity remains light and recent. The vendor has placed one award per year on average since entering the source data in March 2024, with no awards anticipated to complete in the next twenty-four months based on current sourcing patterns. Terra Physics's capability footprint is narrow — geophysical surveying, environmental engineering, and utility clearance work — and is routed entirely through the AECOM prime relationship at Navy environmental remediation sites across Hawaii, Guam, and California.
