About the company
Onterris, Inc., a North Little Rock, Arkansas-based parent entity with seven subsidiaries, operates as a prime contractor and subcontractor delivering environmental testing, air quality analysis, and water and sediment sampling services to federal agencies including the Department of the Army Corps of Engineers, the Department of Homeland Security, the Department of the Interior, and the Department of Veterans Affairs. The vendor competes on full-and-open basis without SBA set-aside designations across a portfolio weighted toward subcontract work (55% of recent awards) under larger environmental and engineering primes, primarily Battelle Memorial Institute.
The corporate structure reflects a specialized, capability-forward organization. Subsidiaries carry explicit service lines: Onterris Laboratories, LLC and Onterris Air Quality Services, LLC target laboratory and air-quality analysis; Onterris Water and Sustainability Services, Inc. addresses water systems and environmental stewardship; Advanced Geoservices Corp. positions geotechnical and subsurface work; and Onterris Government Solutions, Inc. frames federal compliance and contracting. The parent and these entities appear to operate as integrated units rather than separately managed legal entities for contract purposes, with awards flowing to both the parent and named subsidiaries.
Onterris's customer concentration reflects a narrow, specialized federal footprint. Seven distinct agencies account for the award set, with the Department of the Army Corps of Engineers (3 awards), the Department of Homeland Security US Coast Guard (2 awards, $4 thousand combined potential value), and the Department of the Interior Fish and Wildlife Service Region 4 (1 award, $5 thousand combined potential value) representing the plurality by award count. The top customer by potential value is the Department of Health and Human Services National Institutes of Health Construction ($12 thousand). The disparity between combined potential value ($26 thousand) and combined dollars obligated ($641 thousand, 2,461% of potential value) signals that Onterris has invoiced and received far more than its outstanding contract ceilings suggest — typical of mature or completed environmental remediation and testing work where obligation history outpaces remaining contract ceiling.
Onterris places the bulk of its work through two Army Corps of Engineers Indefinite Delivery Contracts: W912DS22D0003 (4 task orders) and W912DS17D0005 (1 task order). The vendor's sole named prime award in the source data is a $4,050 firm fixed-price purchase order from the Veterans Affairs Veterans Integrated Service Network 16 for emergency air quality testing, awarded January 3, 2024 and completed February 16, 2024. Subcontract work centers on Battelle Memorial Institute relationships, where Onterris delivers tissue-dioxins/furans analysis, sediment and water testing, and sample analysis supporting environmental remediation — five sub awards between September 2022 and February 2025 covering contaminated-site investigation and closure work.
NAICS concentration shows seven awards in Testing Laboratories and Services and two in Environmental Consulting Services. Recent activity shows a spike in 2024 (four awards) following a 2022 gap, with the most recent subcontract award in February 2025. No recompete cliff or vehicle concentration appears material across the visible footprint — Onterris operates as a specialized lab and environmental testing subcontractor beneath larger environmental engineering primes rather than as an independent holder of multi-agency IDIQs or GWACs.
