Survey of selected organic compounds in aquifers of New York State excluding Long Island
Roy A. Schroeder, Deborah S. Snavely
1981, Water-Resources Investigations Report 81-47
Samples from 56 wells at 49 sites in New York State, excluding Long Island, were analyzed by gas chromatography/mass spectrometry for the presence of organic compounds designated ' priority pollutants ' by the U.S. Environmental Protection Agency. Most samples were taken from public-supply wells tapping shallow, permeable aquifers, the most...
Hydrologic data for North Creek, Trinity River basin, Texas, 1979
C.C. Kidwell
1981, Open-File Report 81-823
This report contains rainfall and runoff data collected during the 1979 water year for the 21.6-square mile area above the stream-gaging station North Creek near Jacksboro, Texas. A continuous water-stage recording gage was installed at one representative floodwater-retarding structure (site 28-A) on Oct. 5, 1972. The data are collected to...
Peak horizontal acceleration and velocity from strong motion records including records from the 1979 Imperial Valley, California, earthquake
William B. Joyner, David M. Boore, Ronald L. Porcella
1981, Open-File Report 81-365
We have taken advantage of the recent increase in strong-motion data at close distances to derive new attenuation relations for peak horizontal acceleration and velocity. Acceleration data from 183 recordings of 24 earthquakes and velocity data from 62 recordings of 10 earthquakes have been used. This new analysis uses a...
Quality of water in Tibbee Creek and tributaries near West Point, Mississippi
Stephen J. Kalkhoff
1981, Open-File Report 81-406
An intensive water-quality study was conducted on Tibbee Creek and two of its tributaries, Town Creek and Catalpa Creek, on June 19-22, 1979. The data were collected during a period of low discharge and high air temperatures. The water in Tibbee Creek and Catalpa Creek was of much better quality...
Paleomagnetic study of the As Sarat volcanic field, southwestern Saudi Arabia
Karl S. Kellogg, Richard L. Reynolds
1981, Open-File Report 81-675
Four stratigraphic sections through alkali basalt flows of Oligocene-Miocene age (24 to 29 m.y.) in the As Sarat volcanic field, southwestern Saudi Arabia, were sampled for paleomagnetic study. Forty-two magnetically acceptable flows (139 samples) yield a mean direction of magnetization of D=-4.7°, 1=15.2° (α95=4.3°), which defines a paleomagnetic pole at...
Measured sections of the Browns Park Formation (Miocene) in Moffat County, Colorado, 1980
Stanley J. Luft, William L. Thoen
1981, Open-File Report 81-171
Eight partial sections of the Browns Park Formation of Miocene age were measured in Moffat County, northwestern Colorado, during the 1980 field season, as part of a study of the stratigraphy and depositional environments of the formation. These newly measured sections are intended to complement other surface sections of the...
Mekometer measurements in the Imperial Valley
Ronald G. Mason, C.N. Crook, P.R. Wood
1981, Open-File Report 80-2008
During the six weeks following the October 15, 1979 earthquake, parts of the Imperial Valley Mekometer network (Fig. 1) around the Imperial fault to the east of El Centro were re-measured, some repeatedly, in an attempt to assess the coseismic and postearthquake slip on the fault, and horizontal strain adjustment...
Magnitude and chemical quality of base flow of Otter Creek, Tongue River, and Rosebud Creek, southeastern Montana, October 26-November 5, 1977
Roger W. Lee, Steven E. Slagle, James R. Stimson
1981, Open-File Report 80-1298
Hydrologic and chemical data were collected during base-flow conditions on three streams in southeastern Montana from October 26 to November 5, 1977, to characterize groundwater discharge. Maximum measured flow of Otter Creek, an interrupted stream, was 1.2 cubic feet per second. The water chemistry was dominated by sodium, magnesium, and...
Map showing the potentiometric surface of the Magothy aquifer in southern Maryland, August 1980
Frederick K. Mack, Judith C. Wheeler, Stephen E. Curtin
1981, Open-File Report 81-633
This map is based on measurements made in a network of 77 observation wells. Highest levels of the potentiometric surface, 61 to 64 feet above sea level, were near the outcrop or subcrop of the aquifer in topographically high areas of Anne Arundel and northern Prince Georges Counties. The potentiometric...
Petrogenetic modeling of a potential uranium source rock, Granite Mountains, Wyoming
J. S. Stuckless, A.T. Miesch
1981, Professional Paper 1225
Previous studies of the granite of Lankin Dome have led to the conclusion that this granite was a source for the sandstone-type uranium deposits in the basins that surround the Granite Mountains, Wyo. Q-mode factor analysis of 29 samples of this granite shows that five bulk compositions are required to...
Selected drill-stem-test data from the Northern Great Plains area of Montana
Gary W. Levings
1981, Open-File Report 81-326
Selected drill-stem-test data were collected for use in the hydrologic analysis of aquifers in the northern Great Plains area of Montana. To supplement existing data defining the potentiometric surface of various aquifers, shut-in pressures recorded during drill-stem tests of oil and gas test wells were used to calculate the altitude...
