D. Kirk Nordstrom, James W. Ball, R. Blaine McCleskey
2005, Book chapter, Geothermal biology and geochemistry in Yellowstone National Park
Geothermal waters in the earth’s subsurface boil with steam separation and may mix with dilute ground waters (that may or may not contain sulfuric acid from sulfur oxidation), resulting in a wide range of compositions when they discharge and emerge at the surface. As they discharge onto the ground surface...

Unsaturated zone flow processes
John R. Nimmo
2005, Book chapter, Encyclopedia of hydrological sciences, part 13, groundwater
Water flow in the unsaturated zone is greatly influenced by unsaturated hydrostatics (water content, energy, pressure, and retention) and by unsaturated hydrodynamics (diffuse flow and preferential flow). Important multiphase processes include the transport of gases, nonaqueous liquids, and solid particles. Numerous means are available for determination of unsaturated conditions and...

Two pesticide-/herbicide-degrading bacteria, strains ER2 and C147, were isolated...
Geochemistry of speleothem records from southern Illinois: Development of (234U)/(238U) as a proxy for paleoprecipitation
Juanzuo Zhou, C.C. Lundstrom, B. Fouke, S. Panno, K. Hackley, B. Curry
2005, Chemical Geology (221) 1-20
Natural waters universally show fractionation of uranium series (U-series) parent-daughter pairs, with the disequilibrium between 234U and 238U (234U)/(238U) commonly used as a tracer of groundwater flow. Because speleothems provide a temporal record of geochemical variations in groundwater precipitating calcite, (234U)/(238U) variations in speleothems provide a unique method of investigating...
A decrease in discharge-normalized DOC export by the Yukon River during summer through autumn
Robert G. Striegl, G. R. Aiken, M.M. Dornblaser, P.A. Raymond, K.P. Wickland
2005, Geophysical Research Letters (32) 1-4
Climate warming is having a dramatic effect on the vegetation distribution and carbon cycling of terrestrial subarctic and arctic ecosystems. Here, we present hydrologic evidence that warming is also affecting the export of dissolved organic carbon and bicarbonate (DOC and HCO3−) at the large basin scale. In the 831,400 km2 Yukon...

The most direct linkage between weathering and hydrology over 3 million years of soil development in the Merced...
Hydrologic changes in urban streams and their ecological significance
C.P. Konrad, D. B. Booth
2005, American Fisheries Society Symposium (2005) 157-177
Urban development modifies the production and delivery of runoff to streams and the resulting rate, volume, and timing of streamflow. Given that streamflow demonstrably influences the structure and composition of lotic communities, we have identified four hydrologic changes resulting from urban development that are potentially significant to stream ecosystems: increased...
Improved prediction of octanol-water partition coefficients from liquid-solute water solubilities and molar volumes
C. T. Chiou, D.W. Schmedding, M. Manes
2005, Environmental Science & Technology (39) 8840-8846
A volume-fraction-based solvent−water partition model for dilute solutes, in which the partition coefficient shows a dependence on solute molar volume ( ), is adapted to predict the octanol−water partition coefficient (Kow) from the liquid or supercooled-liquid solute water solubility (Sw), or vice versa. The established correlation is...
Population dynamics of wetland fishes: Spatio-temporal patterns synchronized by hydrological disturbance?
Carl R. Ruetz III, J.C. Trexler, F. Jordan, W.F. Loftus, S.A. Perry
2005, Journal of Animal Ecology (74) 322-332
1. Drought is a natural disturbance that can cause widespread mortality of aquatic organisms in wetlands. We hypothesized that seasonal drying of marsh surfaces (i.e. hydrological disturbance) shapes spatio-temporal patterns of fish populations. 2. We tested whether population dynamics of fishes were synchronized by hydrological disturbance (Moran effect) or distance...
Behavior of a chlorinated ethene plume following source-area treatment with Fenton's reagent
F. H. Chapelle, P. M. Bradley, C.C. Casey
2005, Ground Water Monitoring and Remediation (25) 131-141
Monitoring data collected over a 6‐year period show that a plume of chlorinated ethene–contaminated ground water has contracted significantly following treatment of the contaminant source area using in situ oxidation. Prior to treatment (1998), concentrations of perchloroethene (PCE) exceeded 4500 μg/L in a contaminant source area associated with a municipal...

R. L. Smith, S.P. Buckwalter, D.A. Repert, D.N. Miller
2005, Water Research (39) 2014-2023
Nitrate removal by hydrogen-coupled denitrification was examined using flow-through, packed-bed bioreactors to develop a small-scale, cost effective system for treating nitrate-contaminated drinking-water supplies. Nitrate removal was accomplished using a Rhodocyclus sp., strain HOD 5, isolated from a sole-source drinking-water aquifer. The autotrophic capacity of the purple non-sulfur photosynthetic bacterium made...
A direct immunoassay for detecting diatoms in groundwater as an indicator of the direct influence of surface water
C. E. Walker, R. M. Schrock, T. J. Reilly, A. L. Baehr
2005, Journal of Applied Phycology (17) 81-90
Groundwater under the direct influence of surface water (GWUDISW) is of concern in communities where growing public demand on groundwater resources has resulted in increased withdrawals and hydraulic stress near surface water bodies. Under these conditions, contaminants such as methyl-tert butyl ether (MTBE) and biological materials have been detected in...
Geochemical controls on microbial nitrate-dependent U(IV) oxidation
John M. Senko, Joseph M. Suflita, Lee R. Krumholz
2005, Geomicrobiology Journal (22) 371-378
After reductive immobilization of uranium, the element may be oxidized and remobilized in the presence of nitrate by the activity of dissimilatory nitrate-reducing bacteria. We examined controls on microbially mediated nitrate-dependent U(IV) oxidation in landfill leachate-impacted subsurface sediments. Nitrate-dependent U(IV)-oxidizing bacteria were at least two orders of magnitude less numerous...
