Analysis of invertabrate drift samples

The U.S. Geological Survey (USGS) is seeking a qualified laboratory to analyze approximately 180 invertebrate drift samples collected from the Willamette River Basin through this Request for Quotation (RFQ). The contracted services will involve sorting invertebrates from debris, providing expert taxonomic identification, enumerating invertebrates by taxonomic groups and life stages, and characterizing size distributions of sub-samples. The work supports USGS ecohydraulic modeling designed to predict juvenile Chinook salmon habitat and growth potential. Evaluation will prioritize technical capability and past performance significantly over price, with particular preference given to vendors demonstrating prior experience with Willamette River Basin samples. Quotations must be submitted electronically to Anthony Berry at aberry@usgs.gov by January 20, 2026 at 5:00 AM PST and must include a completed SF18 form, a firm fixed-price quote with detailed breakdown, and the vendor's Unique Entity Identifier (UEI).

This opportunity is designated as a Total Small Business set-aside, restricting competition to small business entities. The contract is a firm fixed-price purchase order subject to the Service Contract Act, with a performance period extending from February 2, 2026 through February 1, 2027. No incumbent contractor or specific budget range has been identified in the solicitation materials. The work will be performed at USGS facilities located at 5501 Cook-Underwood Road, Cook, Washington 98605. The contract represents a specialized analytical services requirement classified under NAICS 541380 (Testing Laboratories and Services) and PSC B516 (Special Studies/Analysis—Animal/Fisheries).
