Determination of selected anions in water by ion chromatography
Marvin J. Fishman, Grace Pyen
1979, Water-Resources Investigations Report 79-101
Ion chromatography is a rapid, sensitive, precise, and accurate method for the determination of major anions in rain water and surface waters. Simultaneous analyses of a single sample for bromide, chloride, fluoride, nitrate, nitrite, orthophosphate, and sulfate require approximately 20 minutes to obtain a chromatogram.Minimum detection limits range from 0.01...
Hydrologic effects of annually diverting 131,000 acre-feet of water from Dillon Reservoir, central Colorado
William M. Alley, D. P. Bauer, J.E. Veenhuis, Robert Brennan
1979, Water-Resources Investigations Report 79-2
Because of the increased demands for water in eastern Colorado, principally in the urbanizing Denver metropolitan area, increased diversions of water from Dillon Reservoir are planned. Estimates of end-of-month storage in Dillon Reservoir, assuming the reservoir was in place and 131,000 acre-feet of water were diverted from the reservoir each...
Mid- and North Atlantic multichannel seismic reflection profiles, 7, 8 A, B, and C, 12 E, F, G, H, I, and J, and 13 A, B, C, D, E, F, G, and H
Water Resources Division, U.S. Geological Survey
1979, Open-File Report 78-685
Available are four multichannel profiles collected by Digicon Geophysical Corporation in 1975 using a 48-channel streamer (3600 m long), and a 27.9 cubic liter airgun array. They were processed in Denver on the Phoenix "I" by William C. Petterson. The processing includes demultiplexing and resampling, geometry and common-depth-point, definition, velocity...
Analysis of ground water by different laboratories: a comparison of chloride and nitrate data, Nassau and Suffolk counties, New York
Brian G. Katz, Richard K. Krulikas
1979, Open-File Report 79-1063
Water samples from wells in Nassau and Suffolk Counties were analyzed for chloride and nitrate. Two samples were collected at each well; one was analyzed by the U.S. Geological Survey, the other by a laboratory in the county from which the sample was taken. Results were compared statistically by paired-sample...
A geohydrologic overview for the Pecora Symposium field trip, June 1979
Neil C. Koch
1979, Open-File Report 79-563
The settlement and development of South Dakota has been closely related to both its mineral and water resources In 1874 the discovery of gold in the Black Hills led to the opening and development of the area west of the Missouri River. Towns and farms both here and east of...
Water-resources investigations in Kansas; fiscal year 1978
Harold E. McGovern, L. J. Combs
1979, Open-File Report 79-561
Hydrologic investigations in Kansas during fiscal year 1978 consisted of collecting and analyzing data to assess the State 's water resources, describe the framework of hydrologic systems , and provide quantity and quality of water data for optimum development and management. Surface-water studies were made to analyze long-term records of...
Preliminary catalog of earthquakes in northern Imperial Valley, California, October 1978-December 1978
V. Lamanuzzi, C.E. Johnson, P.T. German
1979, Open-File Report 79-930
The northern section of the Imperial Valley region in southern California is an area of known geothermal resources and high seismicity. To investigate the relationship between geothermal areas and earthquakes in the Imperial Valley, a 16-station seismic network was established in early 1973 by the U. S. Geological Survey. Six...

James M. Frazee Jr., Charles P. Laughlin
1979, Open-File Report 79-336
Brevard County is an area of some 1,300 square miles located on the east coast of central Florida.  The Cape Canaveral quadrangle, in central Brevard, includes part of the Merritt Island National Wildlife Refuge, John F. Kennedy Space Center (NASA), and Cape Canaveral Air Force Station.  The eastern part of...
Faults in parts of north-central and western Houston metropolitan area, Texas
Earl R. Verbeek, Karl W. Ratzlaff, Uel S. Clanton
1979, Miscellaneous Field Studies Map 1136
Hundreds of residential, commercial, and industrial structures in the Houston metropolitan area have sustained moderate to severe damage owing to their locations on or near active faults. Paved roads have been offset by faults at hundreds of locations, butted pipelines have been distorted by fault movements, and fault-induced gradient changes...
