The vulnerability of ground water to contamination in Idaho is being assessed by the IDHW/DEQ (Idaho Department of Health and Welfare, Division of Environmental Quality), using a modified version of the Environmental Orotection Agency DRASTIC methods (Allers and others, 1985). The project was designed as a technique to: (1) Assign priorities for development of ground-water management and monitorin

This is the twenty-eighth in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water conditions.This report, like the others in the series, contains information on well constructi

This report is a summary of data collected under the Utah Water Use Program, a cooperative program between the Utah Division of Water Rights and the United States Geological Survey (USGS).

The report describes the results of a study to assess the sensitivity of streams to acidic deposition in Charles and Anne Arundel Counties, Maryland using a geology-based method. Water samples were collected from streams in July and August 1988 when streams were at base-flow conditions. Eighteen water samples collected from streams in Charles County, and 17 water samples from streams in Anne Arund

An investigation of the hydrologic system in Heber and Round Valleys was conducted to improve understanding of the surface-water and ground-water hydrology and the effects caused by changes in recharge.  Ground water is present in consolidated rocks and in unconsolidated valley-fill deposits, but the principal ground-water reservoir is in the unconsolidated valley-fill deposits.Recharge to the unc

The hydrologic system of the Sevier Lake area, at the terminus of the Sevier Lake drainage basin in west-central Utah, was studied during 1987-88 to determine baseline hydrologic conditions prior to anticipated development.  Sevier Lake was reestablished during 1983-87 on the normally dry playa as a result of record volumes of surface-water runoff, but the lake was receding during the study.  In J

Ground-water resources in the Bountiful area, Utah, were studied to document changes in ground-water conditions and to simulate the effects of increased ground-water withdrawals and changes in recharge. The aquifer system is in basin-fill deposits and is primarily a confined system with unconfined parts along the mountain front.Recharge to the aquifer system was estimated to range from about 22,00

Ground-water resources of the nine county south metropolitan Atlanta region were evaluated in response to an increased demand for water supplies and concern that existing surface water supplies may not be able to meet future supply demands. Previous investigations have suggested that crystalline rock in the study area has low permeability and can not sustain well yields suitable for public supply.

Dissolution and leaching of soil salts by irrigation water is a primary source of Se to shallow groundwater in the western San Joaquin Valley, California. In this study, the mobility and distribution of selenite and selenate in soils with different irrigation and drainage histories was evaluated using sorption experiments and an advection-dispersion model. The sorption studies showed that selenate

Water Resources data for the 1990 water year for New Jersey consists of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This volume of the report contains ground water levels for 218 observation wells and water-quality data for 176 wells. These data represent that part of the

In support of beach-stability research, bedload and suspended sediment were measured during a steady flow of 5,880 ft3/s and receding flows from 12,100 to 5,660 ft3/s in the Colorado River above National Canyon, near Supai, Arizona, October 7-12, 1989. During steady flows, 75 percent of the mean total-sediment discharge of 128 t/d was in suspension and about half the total-sediement load was finer
