The U.S. Geological Survey Office of Acquisitions and Grants awarded a purchase order to Optokhemia Analytical, LLC on September 21, 2026, for microplastics analysis and sampling services, with a ceiling value of $273,000 and an ultimate completion date of September 30, 2030. The award is set aside for small business.
Work encompasses quantitative characterization of microplastic particles from environmental samples collected at agricultural fields, wastewater treatment plants, and surface waters across Oklahoma, Texas, and Galveston Bay. Analysis scope includes measurement and quantification down to 2 micrometers; morphological and chemical characterization using optical, fluorescent, and Raman microscopy; and chemical oxidation and sequential density separation procedures. The contractor will process 20–45 samples annually from 2026 through 2029, delivering results within 120 days of sample receipt in Excel and Presentation format, including microplastic counts, morphological characterization, polymer composition determination, and QA/QC results.
Performance occurs in Norman, Oklahoma. Core analytical work must be performed directly by the contractor; any subcontracted work must be clearly identified and justified.
