Bacteriological water quality in the Lake Pontchartrain basin, Louisiana, following Hurricanes Katrina and Rita, September 2005
Donald M. Stoeckel, Rebecca N. Bushon, Dennis K. Demcheck, Stanley C. Skrobialowski, Christopher M. Kephart, Erin E. Bertke, Brian E. Mailot, Scott V. Mize, Robert B. Fendick Jr.
2005, Data Series 143
The U.S. Geological Survey (USGS), in collaboration with the Louisiana Department of Environmental Quality, monitored bacteriological quality of water at 22 sites in and around Lake Pontchartrain, La., for three consecutive weeks beginning September 13, 2005, following hurricanes Katrina and Rita and the associated flooding. Samples were collected and analyzed...
A multi-disciplinary approach to the removal of emerging contaminants in municipal wastewater treatment plans in New York State, 2003-2004
Patrick J. Philips, Beverley Stinson, Steven D. Zaugg, Edward T. Furlong, Dana W. Kolpin, Kathleen Esposito, B. Bodniewicz, R. Pape, J. Anderson
2005, Conference Paper, Water Environment Federation’s WEFTEC 78th Annual Technical Exhibition and Conference, conference proceedings
Across the United States, there is a rapidly growing awareness of the occurrence and the toxicological impacts of natural and synthetic trace compounds in the environment. These trace compounds, referred to as emerging contaminants (ECs), are reported to cause a range of negative impacts in the environment, such as adverse...
Non-lethal estimation of body composition of Yukon River salmon
F. Joseph Margraf, Kyle J. Hartman, M. Keith Cox
2005, Report
Because of the importance of Chinook salmon to commercial and subsistence fisheries on the Yukon River, further study of the factors that may affect the success of this species and our ability to manage the fisheries is warranted. Critical to these studies is the determination of the amount of lipids...
Hydrogeology and simulation of source areas of water to production wells in a colluvium-mantled carbonate-bedrock aquifer near Shippensburg, Cumberland and Franklin Counties, Pennsylvania
Bruce D. Lindsey
2005, Scientific Investigations Report 2005-5195
This report presents the results of a study by the U.S. Geological Survey in cooperation with the Shippensburg Borough Authority to evaluate the source areas of water to production wells in a colluvium-mantled carbonate-bedrock aquifer in Cumberland and Franklin Counties, Pa. The areal extent of the zone of contribution was...
Hydrogeologic setting, ground-water flow, and ground-water quality at the Lake Wheeler Road research station, 2001-03 : North Carolina Piedmont and Mountains Resource Evaluation Program
Melinda J. Chapman, Richard E. Bolich, Brad A. Huffman
2005, Scientific Investigations Report 2005-5166
Results of a 2-year field study of the regolith-fractured bedrock ground-water system at the Lake Wheeler Road research station in Wake County, North Carolina, indicate both disconnection and interaction among components of the ground-water system. The three components of the ground-water system include (1) shallow, porous regolith; (2) a transition...
Potentiometric surface of the Ozark aquifer in northern Arkansas, 2004
T.P. Schrader
2005, Scientific Investigations Report 2005-5208
The Ozark aquifer in northern Arkansas comprises dolomites, limestones, sandstones, and shales of Late Cambrian to Middle Devonian age, and ranges in thickness from approximately 1,100 feet to more than 4,000 feet. Hydrologically, the aquifer is complex, characterized by discrete and discontinuous flow components with large variations in permeability. The...
Simulation of flow and sediment transport in the white sturgeon spawning habitat of the Kootenai River near Bonners Ferry, Idaho
Charles Berenbrock, James P. Bennett
2005, Scientific Investigations Report 2005-5173
Characterization of sediment transport of the Kootenai River in the white sturgeon spawning reach is needed by the Kootenai River White Sturgeon Recovery Team to predict sediment-transport conditions that improve spawning conditions for the white sturgeon (Acipenser transmontanus) in the Kootenai River near Bonners Ferry, Idaho. The decreasing population and...
Ground-water availability from surficial aquifers in the Red River of the North Basin, Minnesota
Thomas H.C. Reppe
2005, Scientific Investigations Report 2005-5204
Population growth and commercial and industrial development in the Red River of the North Basin in Minnesota, North Dakota, and South Dakota have prompted the Bureau of Reclamation, U.S. Department of the Interior, to evaluate sources of water to sustain this growth. Nine surficial-glacial (surficial) aquifers (Buffalo, Middle River, Two...
Development of regional curves relating bankfull-channel geometry and discharge to drainage area for streams in Pennsylvania and selected areas of Maryland
Jeffrey J. Chaplin
2005, Scientific Investigations Report 2005-5147
Natural-stream designs are commonly based on the dimensions of the bankfull channel, which is capable of conveying discharges that transport sediment without excessive erosion or deposition. Regional curves relate bankfull-channel geometry and discharge to drainage area in watersheds with similar runoff characteristics and commonly are utilized by practitioners of natural-stream...
Water, ice, and meteorological measurements at South Cascade glacier, Washington, balance year 2003
William R. Bidlake, Edward G. Josberger, Mark E. Savoca
2005, Scientific Investigations Report 2005-5210
Winter snow accumulation and summer snow and ice ablation were measured at South Cascade Glacier, Washington, to estimate glacier mass-balance quantities for balance year 2003. The 2003 glacier-average maximum winter snow balance was 2.66 meters water equivalent, which was about equal to the average of such balances for the glacier...
Results of a monitoring program of continuous water levels and physical water properties at the Operable Unit 1 area of the Savage Municipal Well Superfund site, Milford, New Hampshire, water years 2000-03
Philip T. Harte
2005, Open-File Report 2005-1303
The Milford-Souhegan glacial-drift (MSGD) aquifer, in south-central New Hampshire, is an important source of industrial, commercial, and domestic water. The MSGD aquifer was also an important source of drinking water for the town of Milford until it was found to contain high concentrations of volatile organic compounds (VOCs) in...
Hydraulic characterization of overpressured tuffs in central Yucca Flat, Nevada Test Site, Nye County, Nevada
Keith J. Halford, Randell J. Laczniak, Devin L. Galloway
2005, Scientific Investigations Report 2005-5211
A sequence of buried, bedded, air-fall tuffs has been used extensively as a host medium for underground nuclear tests detonated in the central part of Yucca Flat at the Nevada Test Site. Water levels within these bedded tuffs have been elevated hundreds of meters in areas where underground nuclear tests...
Late Devonian Alamo Impact, southern Nevada, USA: Evidence of size, marine site, and widespread effects
Jared R. Morrow, Charles Sandberg, Anita G. Harris
2005, Special Paper of the Geological Society of America 259-280
The early Late Devonian (early Frasnian) Alamo Impact targeted an oceanic, off-platform site in southern Nevada, excavating a crater with a final diameter of 44–65 km. The original crater is now dismembered and buried beneath younger rocks. Consequently, its size and site must be deduced through multiple converging lines of...
Remote sensing of coastal environments
Elijah Ramsey III
2005, Book chapter, Encyclopedia of Coastal Science
Coastal ecosystems are transitional environments that are sensitively balanced between open water and upland landscapes. Worldwide, they exhibit extreme variations in areal extent, spatial complexity, and temporal variability. Sustaining these ecosystems requires the ability to monitor their biophysical features and controlling processes at high spatial and temporal resolutions but within...
National Acid Precipitation Assessment Program Report to Congress: An integrated assessment
Dallas Burtraw, Thomas Butler, Kenneth Colburn, C. Driscoll, David Grigal, editor(s)
2005, Report
Acid deposition, more commonly known as acid rain, occurs when emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) react in the atmosphere (with water, oxygen, and oxidants) to form various acidic compounds. These acidic compounds then fall to earth in either a wet form (rain, snow, and fog) or a dry form (gases, aerosols,...
