Summary of hydrogeologic and ground-water-quality data and hydrogeologic framework at selected well sites, Adams County, Pennsylvania
Rapid population growth in Adams County has increased the demand for ground water and led Adams County planning officials to undertake an effort to evaluate the capabilities of existing community water systems to meet future, projected growth and to begin wellhead-protection programs for public-supply wells. As part of this effort, this report summarizes ground-water data on a countywide scale and

Simulation of ground-water flow and pumpage in Kings and Queens Counties, Long Island, New York
The potential effects of using ground water as a supplemental source of supply in Kings and Queens Counties were evaluated through a 4-layer finite-difference ground-water-flow model with a uniform grid spacing of 1,333 feet. Hydraulic properties and boundary conditions of an existing regional ground-water-flow model of Long Island with a uniform grid spacing of 4,000 feet were refined for use in

Estimation of potential runoff-contributing areas in the Kansas-Lower Republican River basin, Kansas
Digital soils and topographic data were used to estimate and compare potential runoff-contributing areas for 19 selected subbasins representing soil, slope, and runoff variability within the Kansas-Lower Republican (KLR) River Basin. Potential runoff-contributing areas were estimated separately and collectively for the processes of infiltration-excess and saturation-excess overland flow using a se

Hydrogeologic framework and sampling design for an assessment of agricultural pesticides in ground water in Pennsylvania
State agencies responsible for regulating pesticides are required by the U.S. Environmental Protection Agency to develop state management plans for specific pesticides. A key part of these management plans includes assessing the potential for contamination of ground water by pesticides throughout the state. As an example of how a statewide assessment could be implemented, a plan is presented for t

Estimating transmissivity and storage properties from aquifer tests in the Southern Lihue Basin, Kauai, Hawaii
Three to four different analysis methods were applied to the drawdown or recovery data from five constant-rate aquifer tests of 2 to 7 days in length to estimate transmissivity of rocks in the southern Lihue basin, Kauai, Hawaii. The wells penetrate rocks of the Koloa Volcanics and the underlying Waimea Canyon Basalt. Because the wells are located far apart and in previously unexplored areas, it i

Effects of historical land-cover changes on flooding and sedimentation, North Fish Creek, Wisconsin
North Fish Creek, a Wisconsin tributary to Lake Superior, is an important recreational fishery that is potentially limited by the loss of aquatic habitat caused by accelerated flooding and sedimentation. A study of the historical flooding and sedimentation characteristics of North Fish Creek was done to determine how North Fish Creek responded to human-caused changes in land cover since European s

Comparison of methods for computing streamflow statistics for Pennsylvania streams
Methods for computing streamflow statistics intended for use on ungaged locations on Pennsylvania streams are presented and compared to frequency distributions of gaged streamflow data. The streamflow statistics used in the comparisons include the 7-day 10-year low flow, 50-year flood flow, and the 100-year flood flow; additional statistics are presented. Streamflow statistics for gaged locations

Selected elements and organic chemicals in bed sediment and fish tissue of the Tualatin River basin, Oregon, 1992-96
A variety of elements and organic compounds have entered the environment as a result of human activities. Such substances find their way to aquatic sediments from direct discharges to waterways, atmospheric emissions, and runoff. Some of these chemicals are known to harm fish or wildlife, either by direct toxicity, by reducing viability, or by limiting reproductive success. In aquatic systems, sed

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of dissolved arsenic, boron, lithium, selenium, strontium, thallium, and vanadium using inductively coupled plasma-mass spectrometry
The inductively coupled plasma-mass spectrometric (ICP-MS) methods have been expanded to include the determination of dissolved arsenic, boron, lithium, selenium, strontium, thallium, and vanadium in filtered, acidified natural water. Method detection limits for these elements are now 10 to 200 times lower than by former U.S. Geological Survey (USGS) methods, thus providing lower variability at am

Water use in Arkansas, 1995
As part of the National Water-Use Information Program, the U.S. Geological Survey (USGS) stores water-use data in standardized format for different categories of water use. These data are aggregated by county, 4- and 8-digit hydrologic units, and aquifer in the Aggregated Water-Use Data System (AWUDS). Site-specific water-use data for public supply, commercial, industrial, mining, and power genera

Water-level altitudes 1999, water-level changes 1977-99 and 1998-99, and compaction 1973-98 in the Chicot and Evangeline aquifers: Houston-Galveston region, Texas
This report is one in an annual series of reports that depicts water-level altitudes and water-level changes since 1977 and compaction since 1973 in the Chicot and Evangeline aquifers in the Houston-Galveston region, Texas. The report, prepared in cooperation with the City of Houston and the Harris-Galveston Coastal Subsidence District, presents maps for the Chicot and Evangeline aquifers showing
