Ground-water levels in the alluvial aquifer in eastern Arkansas, 1986
Maria Plafcan
1987, Open-File Report 87-545
This report, prepared by the U.S. Geological Survey in cooperation with the Arkansas Soil and Water Conservation Commission, the U.S. Soil Conservation Service, and local Conservation Districts, contains groundwater level measurements of 512 wells tapping the Mississippi River Valley alluvial aquifer of eastern Arkansas. The measurements were made by district...
Tables showing analyses of semiquantitative spectrometry and atomic-absorption spectrophotometry of rock samples collected in the Ugashik, Bristol Bay, and western part of the Karluk quadrangles, Alaska
Frederic H. Wilson, Richard M. O’Leary
1987, Open-File Report 87-419
The accompanying tables list chemical analyses of 337 rock samples that were collected in 1979, 1980, and 1981 in conjunction with geologic mapping in the Ugashik, Bristol Bay, and part of Karluk quadrangles. This work was conducted under the auspices of the Alaska Mineral Resource Assessment Program (AMRAP). This report...
Approximate water-level changes in wells completed in the Chicot and Evangeline aquifers, 1977-87 and 1986-87, and measured compaction, 1973-87, in the Houston-Galveston region, Texas
James F. Williams III, C.E. Ranzau Jr., W.B. Lind
1987, Open-File Report 87-108
This report consists of: (1) four maps that present data on water level changes during 1977-87 and 1986-87 in the Chicot and Evangeline aquifers, and in the Houston-Galveston region, Texas, and (2) one set of graphs and one map that present data on land subsidence caused by compaction of sub-surface...
Seismicity map of the state of New York
C. W. Stover, B.G. Reagor, L.M. Highland, S. T. Algermissen
1987, Miscellaneous Field Studies Map 1282
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 New York, even though earthquakes...
Distribution of radionuclide and trace-elements in ground water, grasses, and surficial sediments associated with the alluvial aquifer along the Puerco River, northeastern Arizona; a reconnaissance sampling program
R. H. Webb, G.R. Rink, B.O. Favor
1987, Open-File Report 87-206
The concentrations of gross alpha radioactivity minus uranium equaled or exceeded 15 picoCuries/L (pCi/L) in five of 14 wells sampled. The concentration of radium-226 plus radium-228 exceeded the primary water quality standard of 5 pCi/L in one well. The concentration of uranium exceeded a recommended limit of 0.035 mg/L in...
Selected water-level data for Mesozoic formations in the upper Colorado River basin in Arizona, Colorado, Utah, and Wyoming; excluding the San Juan Basin
J. F. Weigel
1987, Open-File Report 87-397
The base of the moderately saline water (water that contains from 3,000 to 10,000 mg/L of dissolved solids) was mapped by using available water quality data and by determining formation-water resistivities from geophysical well logs based on the resistivity-porosity, spontaneous-potential, and resistivity-ratio methods. The contour map developed from these data...
