B--Cation exchange capacity and X-ray diffraction of geologic samples

The U.S. Geological Survey (USGS) Central Energy Resources Science Center is seeking a contractor under solicitation 140G0226Q0176 to provide commercial non-personal mineralogical analysis services for rock core samples from the Alaska North Slope. The scope of work involves performing cation exchange capacity (CEC) and whole rock X-ray diffraction (XRD) analysis for 150 samples using full pattern fitting techniques, with a specialized clay type analysis required for a subset of 30 samples. The anticipated award is a firm-fixed-price contract with a period of performance from September 24, 2026, to September 23, 2027, and a required turnaround time of no more than eight weeks for the completion of analyses. The procurement is managed by the USGS Office of Acquisition Grants in Denver, with Jennifer Rollin serving as the Contracting Officer. Evaluation will be based on non-price factors that are considered significantly more important than the total cost. Interested offerors must be registered in the System for Award Management (SAM) with an active Unique Entity ID and submit their quotations electronically by September 22, 2026. Required submission documents include a signed SF-18, UEI number, and point of contact information. Payments will be processed electronically through the Treasury's Invoice Processing Platform.
