The U.S. Geological Survey (USGS), part of the Department of the Interior, is seeking quotes for a fluorometer to enhance its analytical capabilities at the Upper Midwest Environmental Sciences Center (UMESC). This equipment is essential for analyzing chlorophyll a, phycoerythrin, phycocyanin, and colored dissolved organic matter (CDOM), which are critical for studying harmful algal blooms and their toxins in U.S. water resources. The procurement is set aside for small businesses under NAICS code 334516, and the selected vendor will be required to adhere to Federal Acquisition Regulations and maintain compliance with quality control standards. Interested parties must submit their quotes by August 4, 2025, and can direct inquiries to Travis Herberholz at therberholz@usgs.gov.
