BPA for ISOTOPIC/MINERALOGICAL ANALYSIS

The US Geological Survey Office of Acquisitions and Grants seeks to establish a five-year Blanket Purchase Agreement for geologic sample processing and geochemical, mineralogical, and isotopic laboratory analyses, with proposals due September 15 and questions due September 11. An amendment issued September 9 removed the small business set-aside restriction; the procurement is now open to all responsible sources.

Place of performance is Reston, Virginia. The contractor must be registered to ISO/IEC 17025:2017 international quality standards, including ISO 9001:2015 and ISO 9002 specifications. Required analytical capabilities include dry crushing, riffle splitting, pulverizing, sample digestion by lithium metaborate/tetraborate fusion, geochemical analysis by ICP-OES, ICP-MS, INAA, and XRF, X-ray diffraction for mineral analysis, and radiogenic and stable isotope analysis for lead, neodymium, samarium, strontium, oxygen, sulfur, nitrogen, and carbon. Results must include major element oxides to 0.01 weight percent precision and trace elements to specified precision levels, with QA/QC data for every batch. Analytical results and QA/QC data are due within 120 days; processed samples must be returned within 90 days, both in Excel workbook format.

The BPA ceiling is $200,000 over five years (September 30, 2026 through September 29, 2031), with no minimum or maximum order per year. No funding is obligated on the BPA; all charges process as fixed-price BPA calls. USGS will issue calls monthly on an as-needed basis for between 130 and 410 samples per fiscal year. The contractor must bid unit prices per sample across nine distinct services. The NAICS code is 541380, Testing Laboratories and Services. Service Contract Act wage determination 2015-4281 (Rev. 38) applies. The vendor must be registered at SAM.gov and submit quotes via email to brian_baker@ios.doi.gov.
