Principal facts for gravity stations in Dixie; Fairview, and Stingaree valleys, Churchill and Pershing counties, Nevada
D. H. Schaefer, J. M. Thomas, B.G. Duffrin
1984, Open-File Report 84-586
During March through July 1979, gravity measurements were made at 300 stations in Dixie Valley, Nevada. In December 1981, 45 additional stations were added--7 in Dixie Valley, 23 in Fairview Valley, and 15 in Stingaree Valley. Most altitudes were determined by using altimeters or topographic maps. The gravity observations were...
Hydrogeology of a low-level radioactive-waste disposal site near Sheffield, Illinois
J.B. Foster, J.R. Erickson, R. W. Healy
1984, Water-Resources Investigations Report 83-4125
The Sheffield low-level radioactive-waste facility is located on 20 acres of rolling terrain 3 miles southwest of Sheffield, Illinois. The shallow hydrogeologic system is composed of glacial sediments. Pennsylvania shale and mudstone bedrock isolate the regional aquifers below from the hydrogeologic system in the overlying glacial deposits. Pebbly sand underlies...
Magnitude and frequency of floods from urban streams in Leon County, Florida
M.A. Franklin, G.T. Losey
1984, Water-Resources Investigations Report 84-4004
Techniques are provided for estimating flood magnitudes for urban-flow streams in Leon County, Florida, for recurrence intervals of 2, 5, 10, 25, 50, 100, and 500 years. Synthetic flood peaks were generated by using a calibrated lumped-parameter rainfall-runoff model, pan evaporation data from Milton, Florida, and long-term unit rainfall records...
White clays of Pennsylvania
John W. Hosterman
1984, Bulletin 1558-D
The white clays of Pennsylvania are composed chiefly of kaolinite and various amounts of illite. Most of the white clays are silty and a few are sandy. Quartz or chert is the only nonclay mineral in the whitest material; goethite is also present in the colored samples high in iron....
Occurrence of uranium in ground water in the vicinity of the U.S. Department of Energy Feed Materials Production Center, Fernald, Ohio
A. C. Sedam
1984, Open-File Report 85-99
Process wastes are stored on site in rubber-lined and clay-lined pits and in large tanks at the U.S. Department of Energy Feed Materials Production Center (FMPC), where purified uranium and uranium compounds are produced. Water samples collected from off-site domestic and commercial wells in December 1981 and in August 1982,...
Recharge and discharge areas of the Floridan Aquifer in the St. Johns River Water Management District and vicinity, Florida
G. G. Phelps
1984, Water-Resources Investigations Report 82-4058
The Floridan aquifer is the principal source of most of the freshwater used in the St. Johns River Water Management District. An important step in managing water resources is the delineation of recharge and discharge areas. Geohydrologic factors to be considered when delineating recharge and discharge areas include: altitude and...
