USACE Seattle Picks Five for $90M Hazmat Framework

Army Corps of Engineers awards a $90M hazardous waste remediation contract to five firms covering Washington, Oregon, Idaho, and Alaska through 2033

15 Apr 2026

The Army Corps of Engineers Seattle District has awarded a $90 million multi-award contract for hazardous, toxic, and radiological waste remediation, selecting five firms to compete for individual task orders through April 2033. The framework covers military installations, civil works projects, and interagency sites spanning Washington, Oregon, Idaho, and Alaska. The contract was announced April 7, 2026.

The five awardees, Arcadis, Jacobs Engineering Group, and three smaller specialist firms, were chosen from a field of 19 bids solicited online. Work will be assigned competitively as the Corps releases task orders across its contaminated-site portfolio. The contract combines firm-fixed-price and cost-plus-fixed-fee structures, a design that reflects the range of conditions in the pipeline, from well-characterized sites requiring defined remedial actions to more complex locations where scope must adapt as investigation data accumulates.

The Seattle District's remediation workload spans decades of military and industrial contamination, including chlorinated solvents, heavy metals, and PFAS compounds from aqueous film-forming foam used at installations across the region. Cleanup obligations under the Comprehensive Environmental Response, Compensation, and Liability Act and the Resource Conservation and Recovery Act underpin the work, with the EPA's tightening PFAS standards for federal facilities adding further regulatory pressure.

The multi-award structure, rather than a single vendor arrangement, reflects the Corps's stated preference for sustaining competitive discipline across long-duration programs. Officials said the approach is intended to preserve performance incentives and reward technical innovation throughout a seven-year period. The 19 bids submitted signal substantial market interest in the Pacific Northwest remediation pipeline, consistent with broader acceleration in federal environmental cleanup spending in early 2026.

Whether the framework delivers measurable progress for communities near affected installations will depend on how quickly individual task orders are released, and how effectively site investigations translate into funded treatment actions. The pace of that work, and the degree to which advanced characterization technologies are deployed at the most complex sites, will shape the district's cleanup record through the end of the decade.
