Hydrologic, biogeochemical, and radon data collected within and adjacent to the Little Wind River near Riverton, Wyoming (ver. 1.1, January 2019)

The U.S. Geological Survey, in collaboration with the Department of Energy, University of Montana, Northern Arapaho Tribe, and Liverpool John Moores University, is studying the interaction of a contaminated groundwater plume enriched in uranium and other trace elements with water, sediment, and biota along a 3 km reach of the Little Wind River in central Wyoming. The source of the contaminants is from a reclaimed uranium mill site near Riverton, Wyoming. This Data Release makes available data collected from June to September, 2016 and August to September, 2017. Data collected during these time periods include: (1) radon, major-ion, and trace-element concentrations in surface-water, groundwater, and pore-water samples; (2) environmental tracers in groundwater and surface-water samples; (3) seepage rates of shallow groundwater into the Little Wind River; (4) streambed temperature; (5) distribution of uranium in bed sediment, macroalgae, and aquatic insect taxa; (6) river discharge at three sites along the study reach, (7) major-ion and trace-element concentrations in shallow sediment cores collected from the streambed; (8) periphyton biomass accrual on ceramic plates during a 2-week deployment period; and (9) uranium and molybdenum concentration in periphyton samples collected from sites within the study reach.
