A compilation of sulfur dioxide and carbon dioxide emission-rate data from Mount St. Helens during 1980-88
Kenneth A. McGee, Thomas J. Casadevall
1994, Open-File Report 94-212
Airborne monitoring of Mount St. Helens by the USGS began inMay 1980 for sulfur dioxide emissions and in July 1980 forcarbon dioxide emissions. A correlation spectrometer, orCOSPEC, was used to measure sulfur dioxide in Mount St.Helens' plume. The upward-looking COSPEC was mounted in afixed-wing aircraft and flown below and at...

Physical chemical, and biological data were collected in the lower Sun River area of west-central Montana during 1990-92 as part of a U.S. Department of the Interior detailed study of the extent, magnitude, sources, and potential biological impacts of contaminants associated with irrigation drainage. Physical and chemical data were collected...

Estimates of monthly streamflow characteristics at selected sites, Wind River and part of Bighorn River drainage basins, Wyoming
J.G. Rankl, Ellen Montague, B. N. Lenz
1994, Water-Resources Investigations Report 94-4014
Monthly streamflow records from gaging stations with more than 5 years of record were extended to a 50-year base period, 1941-90, using a mixed- station, record-extension model. Monthly streamflow characteristics were computed from the extended record. Four statistical methods--basin characteristics, active-channel width, concurrent measurement, and weighted average were...
Summary of national standards and guidelines for pesticides in water, bed sediment, and aquatic organisms and their application to water-quality assessments
Lisa H. Nowell, Elizabeth A. Resek
1994, Open-File Report 94-44
Current (1993) national standards and guidelines pertaining to pesticide contaminants in water, bed sediment, and fish and shellfish tissues are summarized to provide a condensed reference source for definitions and current values applicable to pesticides in aquatic environmental media. This report facilitates comparison of measured concen- trations of pesticides in...

Peak flow rate and recession-curve characteristics of a karst spring in the Inner Bluegrass, central Kentucky
G.K. Felton, J.C. Currens
1994, Journal of Hydrology (162) 99-118
The flow rate at the terminal spring of a 1929 ha karst ground-water catchment has been continuously monitored for 2 years, and 108 identifiable events were analyzed. The peak flow rates followed a beta frequency distribution with parameters α = 0.365 and γ = 1.135. Events were separated into high-flow and low-flow. High-flow events...

Environmental contaminants in redheads wintering in coastal Louisiana and Texas
T.C. Michot, T. W. Custer, A.J. Nault, C. A. Mitchell
1994, Archives of Environmental Contamination and Toxicology (26) 425-434
Whole body and liver analyses indicated that wintering redheads (Aythya americana; n = 70) in coastal Louisiana (one site) and Texas (two sites) were relatively free of contamination with common trace elements, organochlorines, and hydrocarbons. Most trace elements, including As, Cr, Hg, Mg, Mn, Ni, Pb, Se, Sr,...

Simulation of gas phase transport of carbon-14 at Yucca Mountain, Nevada, USA
N. Lu, B. Ross
1994, Waste Management (14) 409-420
We have simulated gas phase transport of Carbon-14 at Yucca Mountain, Nevada. Three models were established to calculate travel time of Carbon-14 from the potential repository to the mountain surface: a geochemical model for retardation factors, a coupled gas-flow and heat transfer model for temperature and gas flow fields, and...
Methods for estimating magnitude and frequency of floods in the southwestern United States

1994, Open-File Report 93-419
Methods have been developed for estimating magni- tude and frequency of floods at gaged and ungaged sites on streams in the southwestern United States. Estimating equations for ungaged sites that apply to small drainage basins were developed by transferring information from ungaged sites using techniques such as multiple regression...

Documentation of a computer program to simulate transient leakage from confining units using the modular finite-difference, ground-water flow model
S. A. Leake, P.P. Leahy, A. S. Navoy
1994, Open-File Report 94-59
Transient leakage into or out of a compressible fine-grained confining unit results from ground- water storage changes within the unit. The computer program described in this report provides a new method of simulating transient leakage using the U.S. Geological Survey modular finite- difference ground-water flow model (MODFLOW). The new...
Stimulated anoxic biodegradation of aromatic hydrocarbons using Fe(III) ligands
Derek R. Lovley, J.C. Woodward, F. H. Chapelle
1994, Nature (370) 128-131
Contamination of ground waters with water-soluble aromatic hydrocarbons, common components of petroleum pollution, often produces anoxic conditions under which microbial degradation of the aromatics is slow. Oxygen is often added to contaminated ground water to stimulate biodegradation, but this can be technically difficult and expensive. Insoluble Fe(III) oxides, which are...
Gravitational stresses in long symmetric ridges and valleys in anisotropic rock
E. Pan, B. Amadei, W. Z. Savage
1994, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (31) 293-312
The effect of topography and rock mass anisotropy on gravitational stresses in long isolated symmetric ridges and valleys is modeled using an analytical method proposed earlier by the first two authors. The rock mass deforms under a condition of plane strain. A parametric study is presented on the effect of...
