The U.S. Environmental Protection Agency (EPA) Region 10 has awarded a $968,072 Project Grant to The Freshwater Trust (TFT) under the Geographic Programs - Columbia River Basin Restoration (CRBR) Program (CFDA 66.962). The funding will support TFT's efforts to expand a high-resolution mercury monitoring network in the Willamette River Basin, characterize spatiotemporal trends in mercury levels, and engage community scientists in four focal watersheds across the Columbia River Basin. The project involves four main objectives: engaging new communities to expand TFT's participatory dragonfly mercury monitoring program; fine-tuning a national-scale predictive model to estimate site-specific mercury risk; clarifying source attribution for dominant mercury pathways using stable isotope techniques; and testing the impact of specific land management actions on mercury levels. TFT will partner with Oregon State University (OSU) and the U.S. Geological Survey (USGS) to execute the project, which is expected to be completed by November 14, 2028. Key outputs include 240 mercury sampling sites, 3,600 dragonflies analyzed, 50 fish tissue samples, 240 water samples, three basin-wide maps, a best management practices factsheet, and engaging 1,000 community scientists. The overarching outcome is a rigorous estimate of mercury trends and source contributions to empower science-based management for minimizing mercury risk in the Columbia River Basin.
