About GSMAP and GSDRAW
R. B. Taylor, G.I. Selner
1987, Open-File Report 87-496-E
The documentation for GSMAP and GSDRAW attempts a systematic description of these programs. This text is a supplement providing ideas developed during use of the programs and answering some of the common questions asked by new users at training sessions.The first sections of this text are written for new users...
Structure contour map of the top of the Oligocene to Middle Miocene Temblor Formation in the Kettleman Hills and Lost Hills areas, Fresno, Kings, and Kern counties, California
J.L. Zigler, L.S. Frei, C. M. Wentworth, J. A. Bartow
1987, Miscellaneous Field Studies Map 1896
This structure contour map shows the general structural configuration of the Cenozoic section in the area surrounding Kettleman Hills and Lost Hills.  It was compiled from electric well-log data available through April 1982 (Ammann Map Services, 1978; Petroleum Information Corporation, 1982; California Division of Oil and Gas, 1982) and from...
Seismicity map of the state of Vermont
C. W. Stover, B.G. Reagor, L.M. Highland, S. T. Algermissen
1987, Miscellaneous Field Studies Map 1987
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of Vermont, even though earthquakes...
A review of circulation and mixing studies of San Francisco Bay, California
L. H. Smith
1987, Open-File Report 87-534
A description of the major characteristics and remaining unknowns of circulation and mixing in San Francisco Bay has been constructed from a review of published studies. Description of net circulation and mixing over a few days to a few months illustrates best the interactions of major components. The discharge of...
Manmade organic compounds in the surface waters of the United States: a review of current understanding
James A. Smith, Patrick J. Witkowski, Thomas V. Fusillo
1987, Open-File Report 87-209
This report reviews the occurrence and distribution of manmade organic compounds in the surface waters of the United States. On the basis of their aqueous solubilities, nonionic organic compounds partition themselves between water, dissolved organic matter, particulate organic matter, and the lipid reservoirs of aquatic organisms. Ionized organic compounds can...
Nonpoint-source agricultural chemicals in ground water in Nebraska; preliminary results for six areas of the High Plains Aquifer
Hsiu-Hsiung Chen, A.D. Druliner
1987, Water-Resources Investigations Report 86-4338
The reconnaissance phase of a study to determine the occurrence of agricultural chemicals from nonpoint sources in groundwater in six areas, which represented the major provinces of the High Plains aquifer in Nebraska is described. In 1984, water from 82 wells in the 6 study areas was analyzed for nitrate,...
Habitat Suitability Index Models: Black-shouldered kite
Craig A. Faanes, Rebecca J. Howard
1987, FWS/OBS 82/10.130
A review and synthesis of existing information were used to develop a model for evaluating black-shouldered kite habitat quality. The model is scaled to produce an index between 0 (unsuitable habitat) to 1.0 (optimal habitat). Habitat suitability index models are designed for use with the Habitat Evaluation Procedures previously developed...
Hydrogeology of the Cambrian-Ordovician aquifer system at a test well in northeastern Illinois
J.R. Nicholas, M.G. Sherrill, H. L. Young
1987, Water-Resources Investigations Report 84-4165
A 3,475-ft-deep test well was drilled in northeastern Illinois near Lake Michigan and the Illinois-Wisconsin State line as part of a regional hydrologic study of the Cambrian-Ordovician aquifer. The well penetrates the Cambrian-Ordovician aquifer system and 40 ft of Precambrian granite. From oldest to youngest the aquifer system consists of...
Hydrology and water-quality at the Weldon Spring radioactive waste-disposal sites, St. Charles County, Missouri
M. J. Kleeschulte, L. F. Emmett
1987, Water-Resources Investigations Report 87-4169
Water samples from five monitoring wells adjacent to raffinate pits storing low-level radioactive waste contained concentrations of nitrate as nitrogen ranging from 53 to 990 milligrams per liter. Most samples also had maximum concentrations of calcium (900 milligrams per liter), sodium (340 milligrams per liter), sulfate (320 milligrams per liter),...
Water resources of the Zuni tribal lands, McKinley and Cibola Counties, New Mexico
Brennon R. Orr
1987, Water Supply Paper 2227
An evaluation of the water resources of the Zuni tribal lands in west-central New Mexico was made to determine the yield, variability, and quality of water available to the Pueblo of Zuni. This study is needed to aid in orderly development of these resources. Rocks of Permian to Quaternary age...
