About the company
Geosep Services, LLC, based in Moscow, Idaho, operates as a specialized geological laboratory providing apatite fission-track and uranium-lead geochronometric analyses and mineral separation services exclusively to the U.S. Geological Survey as a prime contractor on a mix of purchase orders and delivery orders, with no subcontract footprint. The company competes in full-and-open procurement with no set-aside designation across most of its work, though recent small-business set-aside awards indicate eligibility and occasional use of that posture.
Geosep's capability portfolio centers on thermochronometric dating of geological samples—specifically apatite fission-track (AFT) and uranium-lead (U-Pb) analysis of zircon and apatite minerals, mineral separation of bedrock and detrital samples, and supporting geochronological analyses using conventional fission-track counting with californium-252 irradiation, laser ablation inductively coupled plasma mass spectrometry, and precision microscopy. Recent representative work includes a $44,887.50 U-Pb crystallization age analysis order (35 samples) awarded August 2025, a $88,697.50 detrital zircon U-Pb analysis and mineral separation purchase order dated January 2023, a $66,555 mineral separation and geochronological analysis order (May 2025), and a current $24,820 AFT and U-Pb analysis task for Kuskokwim Mountains samples from August 2026 concluding December 2027. The company carries an underlying $1.3 million five-year indefinite delivery contract with the USGS Geology, Energy & Minerals Science Center, awarded July 2021 and designated 100% small-business set-aside, which serves as the parent vehicle for most task order activity.
Customer concentration is absolute: the USGS Office of Acquisitions and Grants accounts for 64 of 78 total awards ($3 million combined potential value) and the USGS Alaska Science Center for the remaining 14 awards ($250 thousand). The source reports 78 total awards spanning back to 2015, but recent activity has declined—six awards in 2023, three in 2024, five in 2025, and two in 2026 year-to-date through August. Seven awards carrying $226 thousand in combined potential value reach completion within the next twenty-four months and face recompete risk. Geosep sits on three blanket purchase agreements with the USGS: ING15PA00008 (14 task orders, $245 thousand), 140G0121D0011 (11 task orders, $242 thousand), and 140G0219A0002 (10 task orders, $244 thousand). All work is performed in Moscow, Idaho or Portland, Oregon. The company has over thirty years of experience in specialized geological laboratory services to federal earth science and energy initiatives including the Alaska Basins Petroleum System project, Gulf of Mexico Petroleum Geology efforts, and the National Cooperative Geologic Mapping Program.
