About Oneida Environmental, LLC

Written by GovTribe AI ·

Oneida Environmental, LLC, doing business as Oneida Total Integrated Enterprises LLC, is a tribally-owned, Native American-owned limited liability company specializing in comprehensive environmental management and consulting services for federal agencies. Registered in the System for Award Management (SAM.gov), the company holds multiple small business certifications, including 8(a) Program Participant, Minority Owned Business, and Self Certified Small Disadvantaged Business. The firm provides a wide range of environmental services to federal clients, with a primary focus on environmental remediation, compliance, assessment, and specialized environmental consulting across multiple government agencies.

The company's federal contract awards demonstrate extensive expertise in environmental services, particularly for Department of Defense installations. Contract work includes invasive species control, environmental remediation, groundwater fate and transport modeling, stormwater pollution prevention, and environmental compliance support. Oneida Environmental has secured multiple contracts set aside for 8(a) small businesses and Indian Small Business Economic Enterprises, with notable projects at Air Force bases (Cannon, Altus, Whiteman, Little Rock), Naval installations, and Department of Interior sites. Contract values range from small purchase orders around $6,960 to large definitive contracts approaching $5.3 million, covering services such as range residue removal, PFAS remedial investigations, trust resource assessments, and comprehensive environmental management across multiple military installations.

The company holds two significant Indefinite Delivery Vehicle (IDV) contracts that expand its federal service capabilities. The first is a $22 million single-award IDV with Naval Facilities Engineering Command (NAVFAC) for mission, sustainment, and coastal resilience services, valid through September 2029. The second is a $1 million Multiple Award Schedule (MAS) contract with the General Services Administration, running through May 2029, which allows the company to provide environmental consulting services including program management, environmental science, archaeological support, and technical services. These IDVs enable Oneida Environmental to compete for and deliver complex environmental services across federal agencies, with task orders already being issued by NAVFAC, Navy Installations Command, and the Air Force Reserve Command for various environmental monitoring, assessment, and compliance projects.
