Stream and aquifer biology of south-central Texas — A literature review, 1973-97
This report summarizes in table format 32 aquatic vertebrate (primarily fish), 54 aquatic invertebrate, and 13 aquatic plant studies available for the area of the South-Central Texas study unit of the U.S. Geological Survey National Water-Quality Assessment. The studies, published mostly during 1973–97, pertain to the Guadalupe, San Antonio, and Nueces River Basins, the San Antonio-Nueces and Nuec

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Comparison of a nitric acid in-bottle digestion procedure to other whole-water digestion procedures
A hydrochloric acid in-bottle digestion
procedure is used to partially digest wholewater
samples prior to determining
recoverable elements by various analytical
methods. The use of hydrochloric acid is
problematic for some methods of analysis
because of spectral interference. The inbottle
digestion procedure has been
modified to eliminate such interference by
using nitric acid instead of

Water-Level Changes, 1980 to 1997, and Saturated Thickness, 1996-97, In the High Plains Aquifer
The High Plains aquifer underlies one of the major agricultural regions in the world, including parts of eight States--Colorado, Kansas, Nebraska, New Mexico, Oklahoma, South Dakota, Texas, and Wyoming. In the area underlain by the High Plains aquifer (called the High Plains region in this report), the total number of acres irrigated with ground water expanded rapidly after 1940: 1949--2.1 million

Herbicides in the Pecatonica, Trempealeau, and Yahara Rivers in Wisconsin, May 1997-July 1998
In 1997, Wisconsin farmers applied 8.7 million pounds of herbicides on corn. The five most commonly applied herbicides (in lb (pounds) of active ingredient per acre) on corn in 1997 were atrazine, metolachlor, acetochlor, alachlor and cyanazine. A 1996 study by the U.S. Geological Survey (USGS) and the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP) found that the most h

Bottom sediments of Lorence Creek Lake, San Antonio, Texas, reflect contaminant trends in an urbanizing watershed
Historical use of pesticides and rapid urbanization have left their mark on the chemistry of bottom sediments in Lorence Creek Lake (fig. 1) in the northern part of San Antonio, Tex. Several metals, organochlorine compounds (pesticides and polychlorinated biphenyls [PCBs]), and polycyclic aromatic hydrocarbons (PAHs) detected in bottom sediments of the lake have temporal trends indicating anthropo

Areas Susceptible to Irrigation-Induced Selenium Contamination of Water and Biota in the Western United States
The U.S. Department of the Interior (DOI) studied contamination induced by irrigation drainage in 26 areas of the Western United States during 1986-95. Comprehensive compilation, synthesis, and evaluation of the data resulting from these studies were initiated by DOI in 1992. Soils and ground water in irrigated areas of the West can contain high concentrations of selenium because of (1) residual s

Sources and transport of phosphorus and nitrogen during low-flow conditions in the Tualatin River, Oregon, 1991-93
Sources and transport for phosphorous and nitrogen to the Tualatin River, Oregon, were characterized for summer (May through October) low-flow conditions during 1991, 1992, and 1993. Mass balances for water and chemical constituents, which were generated for the main-stem river, provide important context for nutrient-reduction efforts in the basin.

The Virginia Beach shallow ground-water study
IntroductionVirginia Beach is a rapidly growing city of more than 425,000 people. Sources of fresh water within the city, however, are limited. Prior to 1998, the Virginia Beach Public Utilities Department met the city's water needs by purchasing treated drinking water from the City of Norfolk. Because Norfolk had to meet its own requirements, the amount of water available to Virginia Beach was li

Summary of information on synthetic organic compounds and trace elements in tissue of aquatic biota, Clark Fork-Pend Oreille and Spokane River basins, Montana, Idaho, and Washington, 1974-96
As part of the Northern Rockies Intermontane Basins study of the National Water-Quality Assessment Program, data collected between 1974 and 1996 were compiled to describe contaminants in tissue of riverine species. Tissue-contaminant data from 11 monitoring programs and studies representing 28 sites in the study area were summarized. Tissue-contaminant data for most streams generally were lacking.

Public Water-Supply Systems and Associated Water Use in Tennessee, 1995
An inventory of public water-supply systems in Tennessee in 1995 indicated that 530 public water-supply systems supplied water to 4.42 million people, or 84 percent of Tennessee's population. Public-supply water withdrawals totaled 779 million gallons per day, 64 percent (500 million gallons per day) of which was from surface-water sources. All of the surface-water withdrawals for public-water sup

Results of nitrate sampling in the Torrington, Wyoming, Wellhead Protection Area, 1994-98
A monitoring program for nitrate in ground water in and near Torrington, Wyoming was conducted by the Town of Torrington from April 1994 through March 1997, and cooperatively by the Town of Torrington and the U.S. Geological Survey from May 1997 through August 1998. Trends in nitrate concentrations were determined for the period of time covered by both monitoring programs. A significant trend was
