Geologic and hydrologic data collected at test holes NC-4 and NC-14, Manati and Vega Baja, Puerto Rico
Jesús Rodríguez-Martínez, Richard A. Scharlach, Arturo Torres-Gonzalez
1992, Open-File Report 92-126
Test holes NC-4 and NC-14 were drilled in the municipalities of Manati and Vega Baja, respectively, in northern Puerto Rico as part of a study of the ground-water resources in the Northern Coastal Province of Puerto Rico. This study was conducted from 1986 to 1988 by the U.S. Geological Survey...
Description and effects of 1988 drought on ground-water levels, streamflow, and reservoir levels in Indiana
K. K. Fowler
1992, Water-Resources Investigations Report 91-4100
Documentation of the 1988 drought in Indiana was undertaken to aid water-management agencies and planners concerned with periods of below-normal precipitation and their effect on commercial, agricultural, and residential water use. Precipitation, temperature, Palmer Drought Severity Indices, and ground- and surface-water levels from water years 1988 and 1989 were compared...
Hydrogeologic maps of the central Oklahoma aquifer, Oklahoma
Scott C. Christenson, Robert B. Morton, Benard A. Mesander
1992, Hydrologic Atlas 724
This report presents hydrogeologic maps of the Central Oklahoma aquifer. The maps were prepared by measuring water levels in wells during the winder of 1986 and 1987; examination of geophysical logs to determine the altitudes of the top of selected geologic units and the base of fresh ground water; and...
Hydrogeology, water quality, and potential for transport of organochlorine pesticides in ground water at the North Hollywood Dump, Memphis, Tennessee
R. E. Broshears, M. W. Bradley
1992, Water-Resources Investigations Report 91-4022
Geologic, hydrologic, and water-quality data indicate that ground-water contamination is confined to shallow horizons within the unconfined aquifer underlying the North Hollywood Dump in Memphis, Tennessee. The dump is a closed municipal-industrial landfill that has been ranked as Tennessee's potentially most dangerous hazardous-waste site. Toxic constituents of concern at the...
Evaluation of agricultural best-management practices in the Conestoga River headwaters, Pennsylvania; description and water quality of the Little Conestoga Creek headwaters prior to the implementation of nutrient management
D. K. Fishel, M. J. Brown, K. M. Kostelnik, M.A. Howse
1992, Water-Resources Investigations Report 90-4131
The headwaters of the Conestoga River are being studied to determine the effects of agricultural Best-Management Practices on surface-water and ground-water quality. As part of this study, a 5.82-square-mile area of the Little Conestoga Creek headwaters (Small Watershed) was monitored during 1984-86, prior to implementation of Best-Management Practices. This report...
Hydrologic research at the Princeton, Minnesota management systems evaluation area
G. N. Delin, M.K. Landon, J. L. Anderson, R.H. Dowdy
1992, Open-File Report 92-107
The Management Systems Evaluation Area (MSEA) program is part of a multi-scale, inter-agency initiative to evaluate the effects of agricultural management systems on water quality. The program resulted from the integration of the U.S. Department of Agriculture (USDA) Research Plan for Water Quality and the U.S Geological Survey (USGS) Mid-Continent...
Geohydrologic systems in Kansas — Physical framework of the Great Plains aquifer system
Joseph M. Spinazola, R. J. Wolf, Harold E. McGovern
1992, Hydrologic Atlas 722-B
The purpose of this map report is to provide a description of one of the principal geohydrologic systems in Upper Cambrian through Lower Cretaceous rocks in Kansas. The report is the result of an investigation made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one...
Water-supply potential of major streams and the upper Floridan Aquifer in the vicinity of Savannah, Georgia
Reggina Garza, R.E. Krause
1992, Open-File Report 92-629
Long-term pumping from the Upper Floridan aquifer in the Savannah, Georgia, area has lowered ground-water levels, resulting in increased salinity of ground water by seawater encroachment at Hilton Head Island, S.C., and by saltwater intrusion at Brunswick, Ga. Increased pumpage could cause further salinization of the ground-water resources. The Savannah...
Summary of hydrologic data for the San Gabriel River basin and Edwards Aquifer, Georgetown area, Texas, water year 1990
William E. Reeves, Larry F. Land
1992, Open-File Report 92-160
The Edwards aquifer is the principal source of freshwater for municipal, domestic, and industrial users in the Georgetown area.  Other sources of freshwater are Lake Georgetown and the streams draining the San Gabriel River basin.  Lake Georgetown, located on the North Fork San Gabriel River west of Georgetown, is a...
Geohydrologic systems in Kansas physical framework of the western interior plains confining system
R. J. Wolf, Harold E. McGovern, Joseph M. Spinazola
1992, Hydrologic Atlas 722-C
The purpose of this Hydrologic Investigations Atlas is to provide a description of the principal geohydrologic systems in the Upper Cambrian through Lower Cretaceous rocks in Kansas.  This investigation was made as part of the Central Midwest Regional Aquifer-System Analysis (CMRASA). The CMRASA is one of several major investigations by...
Water resources of Massachusetts
Alison C. Simcox
1992, Water-Resources Investigations Report 90-4144
This report describes the water resources of Massachusetts. It contains sections describing the location, use, quality, and management of water resources in Massachusetts, followed by a summary of the surface water and ground-water resources of all 27 river basins designated by the State for planning purposes. The data for each...
Documentation of a digital spatial data base for hydrologic investigations, Broward County, Florida
R.S. Sonenshein
1992, Water-Resources Investigations Report 92-4061
Geographic information systems have become an important tool in planning for the protection and development of natural resources, including ground water and surface water. A digital spatial data base consisting of 18 data layers that can be accessed by a geographic information system was developed for Broward County, Florida. Five...
