“…Concentrations of these chemical species may significantly decrease in ESRP groundwater influenced by recharge from streams and Mud Lake. Recharge from infiltration of precipitation, surface water, or irrigation return flows may also transport O 2 from the atmosphere, CO 2 from the unsaturated zone, and nitrogen from the soil zone (from wet and dry atmospheric deposition; Nilles, 2000;Rattray and Sievering, 2001) to the aquifer, and may cause a localized increase in natural groundwater concentrations of these chemical species. Groundwater inflow to the ESRP aquifer at and near the INL occurs from tributary valleys north of the INL and regional groundwater northeast of the INL.…”

Nuclear research activities at the U.S. Department of Energy (DOE) Idaho National Laboratory (INL) produced liquid and solid chemical and radiochemical wastes that were disposed to the subsurface resulting in detectable concentrations of some waste constituents in the eastern Snake River Plain (ESRP) aquifer. These waste constituents may affect the water quality of the aquifer and may pose risks to the eventual users of the aquifer water. To understand these risks to water quality the U.S. Geological Survey, in cooperation with the DOE, conducted geochemical mass-balance modeling of the ESRP aquifer to improve the understanding of chemical reactions, sources of recharge, mixing of water, and groundwater flow directions in the shallow (upper 250 feet) aquifer at the INL. Modeling was conducted using the water chemistry of 127 water samples collected from sites at and near the INL. Water samples were collected between 1952 and 2017 with most of the samples collected during the mid-1990s. Geochemistry and isotopic data used in geochemical modeling consisted of dissolved oxygen, carbon dioxide, major ions, silica, aluminum, iron, and the stable isotope ratios of hydrogen, oxygen, and carbon. Geochemical modeling results indicated that the primary chemical reactions in the aquifer were precipitation of calcite and dissolution of plagioclase (An 60) and basalt volcanic glass. Secondary minerals other than calcite included calcium montmorillonite and goethite. Reverse cation exchange, consisting of sodium exchanging for calcium on clay minerals, occurred near site facilities where large amounts of sodium were released to the ESRP aquifer in wastewater discharge. Reverse cation exchange acted to retard the movement of wastewater-derived sodium in the aquifer. Regional groundwater inflow was the primary source of recharge to the aquifer underlying the Northeast and Southeast INL Areas. Birch Creek (BC), the Big Lost River (BLR), and groundwater from BC valley provided recharge to the North INL Area, and the BLR and groundwater from BC and Little contaminated groundwater flowed southeast and then southwest from the Naval Reactors Facility industrial waste ditch, with the percentage of wastewater in groundwater decreasing from about 100 percent wastewater adjacent to the waste ditch to about 2 percent wastewater about 0.6 mi south of the waste ditch.

“…Although several watershed-scale studies have investigated atmospheric deposition in small headwater basins in the Rocky Mountains (Turk and Campbell, 1987;Caine and Thurman, 1990;Baron, 1992;Reuss and others, 1993;Campbell and others, 1995;Williams and others, 1996;and Burns, 2002), regional-scale atmospheric deposition data are sparse (Nanus and others, 2003). The National Atmospheric Deposition Program (NADP) provides nationwide estimates of atmospheric deposition (Nilles, 2000;National Atmospheric Deposition Program, 2004). Coverage for high-elevation areas [greater than 2,400 m] in the Rocky Mountains, however, is limited.…”

“…Deposition of pollutants occurs both by wet (rain and snow) and dry (accumulation of particles and gases) processes, although dry deposition is estimated to account for less than 25 percent of total sulfur and nitrogen deposition in the Western United States (U.S. Environmental Protection Agency, 2008). One way to evaluate the effect of anthropogenic emissions on the environment is with atmospheric monitoring networks that provide long-term consistent data that can be used to track temporal and spatial trends in regional air quality (Nilles, 2000). Such assessments are important to scientists, resource managers, and policymakers for evaluating the effectiveness of regulatory actions on improving the water quality of precipitation and surface water.…”
