The U.S. Geological Survey (USGS) is seeking qualified vendors to provide analysis of pyrogenic carbon in ash, soil, and sediment samples from wildfire-affected areas under the Request for Quotations (RFQ) number 140G0325Q0051. The project aims to analyze up to 200 samples, with a completion deadline of June 30, 2025, requiring vendors to submit firm, fixed price quotations by March 11, 2025, along with detailed technical approaches and evidence of past performance in similar analyses. This initiative is crucial for understanding the environmental impacts of wildfires, supporting ongoing research and policymaking efforts in affected regions.
