2003, Water-Resources Investigations Report 2003-4048
Disposal of wastewater to unlined infiltration ponds near the Idaho Nuclear Technology and Engineering Center (INTEC), formerly known as the Idaho Chemical Processing Plant, at the Idaho National Engineering and Environmental Laboratory (INEEL) has resulted in the formation of perched water bodies in the unsaturated zone (Cecil and others, 1991)....
Surface-water hydrologic data for the Houston metropolitan area, Texas, water years 1990-95
Debra A. Sneck-Fahrer, Fred Liscum, Jeffery W. East
2003, Open-File Report 2003-70
During water years 1990–95, data were collected at 24 U.S. Geological Survey streamflow-gaging stations, 21 rain gages, and 6 water-quality stations in the Houston metropolitan area, Texas. The data were collected as part of the Houston Urban Runoff Program, which began in water year 1964. Annual peaks were defined for...
Hydrogeology and Ground-Water Quality of Brunswick County, North Carolina

2003, Water-Resources Investigations Report 2003-4051
Brunswick County is the southernmost coastal county in North Carolina and lies in the southeastern part of the Coastal Plain physiographic province. In this report, geologic, hydrologic, and chemical data were used to investigate and delineate the hydrogeologic framework and ground-water quality of Brunswick County. The major aquifers and their...
Estimating Ground-Water Recharge from Precipitation on Whidbey and Camano Islands, Island County, Washington, Water Years 1998 and 1999
S. S. Sumioka, H. H. Bauer
2003, Water-Resources Investigations Report 2003-4101
Ground-water recharge from precipitation to unconsolidated deposits on Whidbey and Camano Islands, Washington, was estimated for water years 1998-99 using a near-surface water-balance method and a chloride mass-balance method. A daily near-surface water-balance method, the Deep Percolation Model (DPM), was used to simulate water budgets for October 1, 1997 through...
Worldwide asbestos supply and consumption trends from 1900 to 2000
Robert L. Virta
2003, Open-File Report 2003-83
The use of asbestos is one of the most controversial issues surrounding the industrial minerals industry. Its carcinogenic nature, an overall lack of knowledge of minimum safe exposure levels, its widespread use for more than 100 years, and the long latency for the development of lung cancer and mesothelioma are...
Geologic database for digital geology of California, Nevada, and Utah— An application of the North American Data Model
David R. Bedford, Steve Ludington, Constance M. Nutt, Paul A. Stone, David M. Miller, Robert J. Miller, David L. Wagner, George J. Saucedo
2003, Open-File Report 2003-135
The USGS is creating an integrated national database for digital state geologic maps that includes stratigraphic, age, and lithologic information. The majority of the conterminous 48 states have digital geologic base maps available, often at scales of 1:500,000. This product is a prototype, and is intended to demonstrate the types...
Preliminary northeast Asia geodynamics map
Leonid M. Parfenov, Alexander I. Khanchuk, Gombosuren Badarch, Robert J. Miller, Vera V. Naumova, Warren J. Nokleberg, Masatsugu Ogasawara, Andrei V. Prokopiev, Hongquan Yan
2003, Open-File Report 2003-205
This map portrays the geodynamics of Northeast Asia at a scale of 1:5,000,000 using the concepts of plate tectonics and analysis of terranes and overlap assemblages. The map is the result of a detailed compilation and synthesis at 5 million scale and is part of a major international collaborative study...
Assessment of habitat and streamflow requirements for habitat protection, Usquepaug–Queen River, Rhode Island, 1999–2000
David S. Armstrong, Gene W. Parker
2003, Open-File Report 2002-438
The relations among stream habitat and hydrologic conditions were investigated in the Usquepaug–Queen River Basin in southern Rhode Island. Habitats were assessed at 13 sites on the mainstem and tributaries from July 1999 to September 2000. Channel types are predominantly low-gradient glides, pools, and runs that have a sand and...
Methods of analysis by the U.S. Geological Survey Organic Geochemistry Research Group: Determination of acetamide herbicides and their degradation products in water using online solid-phase extraction and liquid chromatography/mass spectrometry
E.A. Lee, A.P. Strahan
2003, Open-File Report 2003-173
An analytical method for the determination of 6 acetamide herbicides (acetochlor, alachlor, dimethenamid, flufenacet, metolachlor, and propachlor) and 16 of their degradation products in natural water samples using solid-phase extraction and liquid chromatography/mass spectrometry is described in this report. Special consideration was given during the development of the method to...
Reactive-transport simulation of phosphorus in the sewage plume at the Massachusetts Military Reservation, Cape Cod, Massachusetts
David L. Parkhurst, Kenneth G. Stollenwerk, John A. Colman
2003, Water-Resources Investigations Report 2003-4017
The subsurface transport of phosphorus introduced by the disposal of treated sewage effluent to ground-infiltration disposal beds at the Massachusetts Military Reservation on western Cape Cod was simulated with a three-dimensional reactive-transport model. The simulations were used to estimate the load of phosphorus transported to Ashumet Pond during operation of...
Reconnaissance of mercury in lakes, wetlands, and rivers in the Red River of the North Basin, North Dakota, March through August 2001
Steven K. Sando, G.J. Wiche, R.F. Lundgren, Bradley A. Sether
2003, Water-Resources Investigations Report 2003-4078
Devils Lake rose dramatically during the 1990's, causing extensive flood damages. Because of the potential for continued flooding, the U.S. Army Corps of Engineers has been conducting studies to evaluate the feasibility of constructing and operating an outlet from Devils Lake. The occurrence of mercury in lakes, wetlands, and rivers...
A gentic survey of Salvinia minima in the southern United States
Paul T. Madeira, Colette C. Jacono, Phil Tipping, Thai K. Van, Ted D. Center
2003, Aquatic Botany (76) 127-139
The genetic relationships among 68 samples of Salvinia minima (Salviniaceae) were investigated using RAPD analysis. Neighbor joining, principle components, and AMOVA analyses were used to detect differences among geographically referenced samples within and outside of Florida. Genetic distances (Nei and Li) range up to 0.48, although most are under 0.30, still relatively...
Incorporating Science into Decision-Making
Herman A. Karl, Christine E. Turner
2003, Science (300) 1370-1370
Alan Leshner's Editorial “Public engagement with science” (14 Feb., p. 977) highlights a conundrum: Why is science often ignored in important societal decisions, even as the call for decisions based on sound science escalates? One reason is that decision-making is often driven by a variety of nonscientific, adversarial,...

Toxicity of lead-contaminated sediment to mute swans
D. D. Day, W. N. Beyer, D. J. Hoffman, Alexandra Morton, L. Sileo, D. J. Audet, M. A. Ottinger
2003, Archives of Environmental Contamination and Toxicology (44) 510-522
Most ecotoxicological risk assessments of wildlife emphasize contaminant exposure through ingestion of food and water. However, the role of incidental ingestion of sediment-bound contaminants has not been adequately appreciated in these assessments. This study evaluates the toxicological consequences of contamination of sediments with metals from hard-rock mining and smelting activities....
