Data from the Woodland land-subsidence monitoring station, Yolo County, California, water years 1988-92
M. E. Ikehara
1995, Open-File Report 94-494
A land-subsidence monitoring study was initiated in 1985 for the purpose of collecting data in Sacramento Valley, California, to document land-surface subsidence and to measure sediment compaction in response to ground-water pumping. Lithologic and geophysical logs obtained from the deeper of two boreholes drilled in 1987 near Woodland, California, are...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of organochlorine pesticides and polychlorinated biphenyls in bottom sediment by dual capillary-column gas chromatography with electron-capture detection
William T. Foreman, Brooke F. Connor, Edward T. Furlong, Deborah G. Vaught, Leslie M. Merten
1995, Open-File Report 95-140
A method for the determination of 30 individual organochlorine pesticides, total toxaphene, and total polychlorinated biphenyls (PCBs) in bottom sediment is described. The method isolates the pesticides and PCBs by solvent extraction with dichlorobenzene, removes inorganic sulfur, large naturally occurring molecules, and other unwanted interferences by gel permeation chromatography, and...
Geologic map of the Littlefield Quadrangle, northern Mohave County, Arizona
George H. Billingsley
1995, Open-File Report 95-559
The Littlefield 7.5' quadrangle lies in the extreme northwestern corner of Mohave County, Arizona (fig. 1). Elevations range from about 536.5 m (1,760 ft) at the Virgin River (south-central edge of quadrangle) to 975 m (3,200 ft) in the Beaver Dam Mountains (northeastern corner of quadrangle). Interstate Arizona Highway 15...

Preliminary geologic map of the Little Piute Mountains, San Bernardino County, California
Keith A. Howard, Michael L. Dennis, Karl E. Karlstrom, Geoffrey A. Phelps
1995, Open-File Report 95-598
Introduction The Little Piute Mountains in the eastern Mojave Desert expose a series of folds and thrust faults involving metamorphosed Paleozoic strata (Miller and others, 1982; Stone and others, 1983). Detailed mapping of these structures was undertaken to help elucidate regional Mesozoic structural evolution. Earlier geologic maps were prepared by...
Hydrologic data from the lower Cedar River Basin, Iowa, 1989-91
P.M. Schulmeyer, K.K. Barnes, P. J. Squillace
1995, Open-File Report 94-711-W
Hydrologic data were collected from May 1989 through July 1991 from the Cedar River and the adjacent alluvial aquifer. The data were collected during various flow regimes of the river to evaluate the movement of agricultural chemicals between surface water and ground water. Water-quality samples from 34 surface-water sites and...
