Water-quality reconnaissance of the north Dade County solid-waste facility, Florida
D.J. McKenzie
1982, Open-File Report 82-753
A water-quality sampling reconnaissance of the north Dade County solid-waste disposal facility (landfill) near Carol City, Florida, was conducted during 1977-78. The purpose of the reconnaissance was to determine selected quality characteristics of the surface- and ground-water of the landfill and contiguous area; and to assess, generally, if leachate produced...
A study of trends in dissolved oxygen and fecal coliform bacteria at NASQAN stations
Richard A. Smith, Richard B. Alexander
1982, Open-File Report 82-1019
Most stations in the U.S. Geological Survey's National Stream Quality Accounting Network show no significant trend in either dissolved oxygen concentration or fecal coliform bacteria population for the period October 1974. through October 1981. Of the stations which do show trends, however, most show improved water quality: thirty-one of a...
Magnitude and frequency of floods from selected drainage basins in South Dakota
Lawrence D. Becker
1982, Water-Resources Investigations Report 82-31
The 2-, 5-, 10-, 25-, 50-, and 100-year floods are determined for gaged sites on 120 selected, small drainage basins in South Dakota. These estimates are from the frequency curves defined from the streamflow records. Short-term records for 66 sites were extended on the basis of long-term climatic records and...
Ground-water resources of the White River basin, Delaware County, Indiana
Leslie D. Arihood, Wayne W. Lapham
1982, Water-Resources Investigations Report 82-47
The ground-water resources of the White River basin in and near Delaware County, Indiana, were investigated by mapping the aquifers, calculating their hydraulic properties, determining the distribution of potentiometric head, and determining some of the components of the ground-water budget from data collected in the field. This information was used...
The evaluation of selected one-dimensional stream water quality models with field data
Steve C. McCutcheon
1982, Open-File Report 82-851
The U.S. Geological Survey One-Dimensional Stream Water-Quality Model, QUAL II Stream Water-Quality Routing Model, the U.S. Army corps of Engineers Water Quality for River Reservoir Systems Model, and the M.I.T. Transient Water Quality Network were evaluated and compared using actual water-quality data collected by the U.S. Geological Survey. The field...
An index of geophysical well logging in Virginia by the U.S. Geological Survey
M. Patrick Mulheren, J. D. Larson, Herbert T. Hopkins
1982, Open-File Report 82-432
Geophysical logs have been obtained in more than 170 wells in Virginia by the U.S. Geological Survey since 1968. These logs include natural gamma, electric, caliper, temperature, fluid conductivity, and fluid velocity. Most of the logs are for wells in the Coastal Plain Province of eastern Virginia. Geophysical logs aid...
Reconnaissance water-balance study of Lake Gregory, California
C.E. McConaughy
1982, Open-File Report 82-367
A study was made to determine the magnitude and distribution of the surface-water inflow and outflow (water balance) of the Lake Gregory basin in southern California. Data were collected from April 1979 through June 1981. Runoff during the study period varied greatly with the majority of inflow occurring between December...
Ground-water resources of the White River basin, Hamilton and Tipton Counties, Indiana
Leslie D. Arihood
1982, Water-Resources Investigations Report 82-48
An analysis of the ground-water resources of the Hamilton and Tipton Counties was based on data from about 1,900 well logs, 125 water levels in 125 wells, streamflow measurements at 57 sites, and municipal- and industrial-pumpage records. These data were used to map the flow system and construct a three-dimensional...
Chloride Concentration in Water from the Upper Permeable Zone of the Tertiary Limestone Aquifer System, Southeastern United States
Craig L. Sprinkle
1982, Water-Resources Investigations Report 81-1103
INTRODUCTION The tertiary limestone aquifer system of the southeastern United States is a sequence of carbonate rocks referred to as the Floridan aquifer in Florida and the principal artesian aquifer in Georgia, Alabama, and South Carolina. More than 3 billion gallons of water are pumped daily from the limestone aquifer; and...
Hydrology of the Floridan Aquifer in Northwest Volusia County, Florida
A. T. Rutledge
1982, Open-File Report 82-108
Northwest Volusia County, in east-central Florida, is a 262-square-mile area including the southern part of the Crescent City Ridge and the northern tip of the DeLand Ridge. The hydrogeologic units in the area include the Floridan aquifer, which is made up of parts of the Lake City Limestone, the Avon...
