The U.S. Geological Survey is offering a funding opportunity through a Cooperative Agreement for a partner affiliated with the Great Lakes – Northern Forest Cooperative Ecosystem Studies Unit (CESU). This initiative aims to support research in developing sensor technology for measuring organic contaminants, specifically per- and polyfluoroalkyl substances (PFAS), in water. The funding, which ranges from $1 to $200,000, is intended to enhance scientific understanding and technological capabilities in environmental monitoring. Interested applicants must be participating partners of the Great Lakes – Northern Forest CESU Program, and applications are due by February 17, 2025.
