Tanaq Environmental

What Tanaq Environmental does

Tanaq Environmental is a division of St. George TANAQ Corporation, an Alaska Native Corporation established in 1973 under the Alaska Native Claims Settlement Act and owned by approximately 350 Unangan shareholders of St. George Island, Alaska. The division delivers environmental consulting and remediation services through three core subsidiaries — Tanaq Environmental LLC, Tanaq Engineering & Sustainability LLC, and Helios Resources Ltd. — plus four joint ventures (Tanaq-MES, Tanaq-ECM, Tanaq-MMG, Tanaq-Sundance). Its technical capabilities span PFAS groundwater treatment via ion-exchange resin, in situ enhanced reductive dichlorination (ERD) and chemical oxidation, soil mixing with chemical oxidation, deep monitoring well installation (up to 650 feet), Performance-Based Remediation (PBR), CERCLA remedial investigations/feasibility studies, Military Munitions Response Program (MMRP), and Environmental Compliance Services for HTRW sites.

The division's business model is anchored in the SBA 8(a) Alaska Native Corporation contracting pathway, which permits sole-source federal awards up to $100M for DoD and $25M for other agencies, with non-protestable awards that materially shorten federal procurement cycles. Primary customers are DoD installations (Mountain Home AFB, Luke AFB, MacDill AFB, Avon Park AFR), the U.S. Army Corps of Engineers (notably the Los Angeles District), and the EPA. Documented operational outcomes include treatment of approximately 20 million gallons of PFAS-contaminated groundwater at Mountain Home AFB (2018–2020) with no breakthrough, and Site Closeout at three MacDill AFB/Avon Park AFR sites within 2.5 years of task order award. The corporate parent has also extended operations into Antarctica via TANAQ Government Services supporting NAVSUP Fleet Logistics Center San Diego.

Revenue is generated exclusively through federal contract awards (professional services model) on a project-based, negotiated pricing basis; pricing is not publicly disclosed. Marketing and customer acquisition run through SBA 8(a) program visibility, industry conferences (SAME SBC, National 8(a) Small Business Conference), direct contracting officer engagement, and the corporation's website. Quality is reinforced by ISO 9001:2015 certification. Service delivery geographies span Alaska, Arizona, Florida, Idaho, and nationwide U.S., with selective international exposure through Antarctica logistics support.
