The U.S. Geological Survey (USGS) is conducting market research to identify qualified businesses capable of providing X-ray fluorescence (XRF) scanning services for sediment samples. The primary objective is to analyze split sediment cores from lakes in California, Alaska, and Washington to differentiate between earthquake-triggered sediment flows and those caused by flooding, which is crucial for understanding earthquake hazards. This non-destructive elemental analysis will aid in enhancing the understanding of seismic activity through detailed elemental studies. Interested vendors must submit their capability statements electronically by June 13, 2025, to Anthony Berry at aberry@usgs.gov, with the potential contract lasting four months from the award date and no government property provided for the task.
