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...
Ground-water levels in Wyoming, 1976 through 1985
H.I. Kennedy, C.B. Oberender
1987, Open-File Report 87-456
Groundwater levels are measured periodically in a network of 84 observation wells in Wyoming, mostly in areas where groundwater is used in large quantities for irrigation or municipal purposes. The program is conducted by the U.S. Geological Survey in cooperation with the Wyoming State Engineer and the Wyoming Economic Development...
Operation of hydrologic data collection stations by the U.S. Geological Survey in 1987
Alberto Condes de la Torre
1987, Open-File Report 87-563
The U.S. Geological Survey operates hydrologic data collection stations nationwide which serve the needs of all levels of government, the private sector, and the general public, for water resources information. During fiscal year 1987, surface water discharge was determined at 10,624 stations; stage data on streams, reservoirs, and lakes were...
Ground-water flow and quality near Canon City, Colorado
G. A. Hearne, D. W. Litke
1987, Water-Resources Investigations Report 87-4014
Water in aquifers that underlie the Lincoln Park area near Canon City, Colorado, contains measurable concentrations of chemical constituents that are similar to those in raffinate (liquid waste) produced by a nearby uranium ore processing mill. The objective of this study was to expand the existing geohydrologic data base by...
Ground-penetrating radar study of the thickness and extent of sediments beneath Silver Lake, Berlin and Meriden, Connecticut
F.P. Haeni, D. K. McKeegan, D.R. Capron
1987, Water-Resources Investigations Report 85-4108
A short-pulse ground-penetrating radar system was used to determine the extent and thickness of organic-rich lake-bottom sediments in Silver Lake in south-central Connecticut. Four mi of ground-penetrating radar profiles were obtained along traverses of the frozen lake during March 1984. The radar waves penetrated 6 inches of snow, 1 ft...
Water resources data, Louisiana, water year 1986
D.D. Carlson, L.J. Dantin, C.R. Garrison, C.G. Stuart
1987, Water Data Report LA-86-1
Water resources data for the 1986 water year for Louisiana consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels and water quality of ground water. This report contains records for water discharge at 70 gaging stations;...
