About the company
Desotec US LLC, a Pennsylvania-based industrial wastewater treatment company, provides granular activated carbon replacement and removal services to the Department of the Air Force as a prime contractor (57% of recent awards) and as a specialized subcontractor on Department of Energy nuclear-security programs. The vendor operates without SBA set-aside designations across its federal footprint and competes full-and-open on single-award and limited-competition vehicles at Air Force installations.
Desotec's federal customer base is highly concentrated within the Department of the Air Force. The Air Force Sustainment Center and Air Force Materiel Command account for 100% of the vendor's prime awards (4 total, $1.5 million combined potential value), with all work performed at Hill Air Force Base, Utah. The vendor also holds subcontract relationships with the Department of Energy National Nuclear Security Administration, subcontracting to Consolidated Nuclear Security, LLC on Y-12 and Pantex management-and-operating contracts, and to OCH JV on Environmental Protection Agency Region 10 Superfund remediation work. Work characterization across both prime and sub roles centers on industrial wastewater treatment, hazardous waste removal and disposal, and environmental remediation — NAICS 311999 (All Other Miscellaneous Chemical Product and Preparation Manufacturing) and Hazardous Waste Treatment and Disposal dominate the award portfolio, with PSC 4400 (Maint/Repair/Rebuild Of Equipment–Plumbing, Heating, And Waste Disposal Equipment) reflecting the core service delivery.
Desotec's primary vehicle is a $1.5 million single-award Indefinite Delivery Contract, FA820124D0003, awarded by the Air Force Sustainment Center on July 22, 2024, with performance through July 21, 2029. Three task orders totaling $118 thousand in combined potential value have been issued under this vehicle; representative work includes a $70.2 thousand delivery order placed September 27, 2024, for GAC removal at Hill AFB with completion December 27, 2024, and a $25.3 thousand delivery order issued July 20, 2026, for GAC replacement in Industrial Wastewater Treatment Plant Tank C with ultimate completion January 30, 2027. Award activity shows modest recent volume — four awards in 2024, one in 2025, two in 2026 — with one award reaching ultimate completion within the next twenty-four months. Combined obligated dollars across all seven awards total $676 thousand against a combined potential value of $1.6 million, reflecting the early execution phase of a long-term maintenance contract.
