Potentiometric surfaces on Long Island, New York -- A bibliography of maps
D. A. Smolensky
1983, Open-File Report 84-70
Historic water-level records form a major basis for ground-water investigations and water-management decisions on Long Island. Potentiometric-surface maps, one of the major sources of historic data, are scattered within the literature or are available only through the publisher or sponsoring agency. This report presents a comprehensive list of available water-table...
Microcumpter computation of water quality discharges
Dennis R. Helsel
1983, Open-File Report 82-901
A fully prompted program (SEDQ) has been developed to calculate daily and instantaneous water quality (QW) discharges. It is written in a version of BASIC, and requires inputs of gage heights, discharge rating curve, shifts, and water quality concentration information. Concentration plots may be modified interactively using the display screen....
Water-resources investigations of the U.S. Geological Survey in Wyoming, fiscal years 1981 and 1982
S. L. Green
1983, Open-File Report 83-254
This report contains lists and location maps of streamflow and reservoir stations, peak-flow partial-record stations, water quality stations, sediment stations, and ground-water stations that are currently being operated. Water-resources appraisal projects in Wyoming are also described, including many that are related to development of energy resources. The general locations of...
An aeromagnetic interpretation of eleven map sheets, scale 1:250,000, in the southern Najd and part of the southern Tuwayq quadrangles, Kingdom of Saudi Arabia
Andrew Griscom
1983, Open-File Report 82-1048
Eleven magnetic interpretation maps (scale 1:250,000) have been prepared for the area .of. exposed crystalline rocks in the Southern Najd and part of the Southern Tuwayq quadrangles (scale 1:500,000) from available published data. Boundaries of a variety of rock units that produce distinctive magnetic anomalies .or anomaly patterns are delineated....
Rock property measurements and analysis of selected igneous, sedimentary, and metamorphic rocks from worldwide localities
Gordon R. Johnson
1983, Open-File Report 83-736
Dry bulk density and grain density measurements were made on 182 samples of igneous, sedimentary, and metamorphic rocks from various world-wide localities. Total porosity values and both water-accessible and helium-accessible porosities were calculated from the density data. Magnetic susceptibility measurements were made on the solid samples and permeability and streaming...
The nonopaque, detrital heavy mineralogy of the Morrison Formation near Crownpoint, San Juan Basin, New Mexico
Paula L. Hansley
1983, Open-File Report 83-191
Description and quantification of the nonopaque, detrital heavy mineralogy of the Upper Jurassic Morrison Formation in the southwestern part of the San Juan Basin have helped to identify stratigraphic trends, source-area lithologies, and zones of post-depositional alteration possibly related to uranium mineralization. A synthesis of stratigraphic variations in mineral species...
Ground-water data for Michigan 1982
G.C. Huffman
1983, Open-File Report 83-753
Water levels, locations, depths, and aquifers tapped are given for 117 observation wells. Tabulated data include extremes of water levels for 1982 and for the period of record, pumpage of most major ground-water users in the State, and quality data on selected wells. The largest reported user of ground-water, the...
Base flow and ground water in upper Sweetwater Valley, Tennessee
R. D. Evaldi, J.G. Lewis
1983, Water-Resources Investigations Report 83-4068
Base flow measurements showed interbasin transfer of water among sub-basins of upper Sweetwater Valley. In general, topographically higher sub-basins have deficient surface outflow unless significant spring flow occurs in the basin. Topographically lower areas adjacent to the main channel of Sweetwater Creek generally have surplus flow. Major flow surpluses were...
Results of a test well in the Nanafalia Formation near Melvin, Choctaw County, Alabama
M. E. Davis, A.K. Sparkes, B.S. Peacock
1983, Water-Resources Investigations Report 82-4108
Test drilling at Melvin, Choctaw County, Alabama, discloses that the Nanafalia Formation (Paleocene) contains freshwater in sand at a distance of 25 miles downdip from the outcrop area. A nearby fault on the north side of Gilberttown-Pickens fault zone does not appear to affect either the head or the water...
Bryozoan fauna of the Upper Clays Ferry, Kope, and Lower Fairview formations (Edenian, Upper Ordovician) at Moffett Road, northern Kentucky
Olgerts L. Karklins
1983, Open-File Report 83-21
The geology, water movement, and sediment characteristics in the upstream part of the Spring River basin have been appraised, to assist the U.S. EPA in their study of dioxin contamination in the area. The U.S. Environmental Protection Agency has confirmed that the dioxin compound, TCDD (2,3,7 ,8-tetrachlorodibenzo-p-dioxin), is present in...
A reconnaissance geochemical survey of the Clarion River Roadless Area, Allegheny National Forest, Elk County, Pennsylvania
N. L. Hickling, Stanley P. Schweinfurth, Betty M. Adrian
1983, Open-File Report 83-22
Semiquantitative emission spectrographic analyses for 31 elements were determined on 9 stream-sediment samples and 18 bedrock samples from the Clarion River Roadless Area, Elk County, Pennsylvania. All sample localities are given in Universal Transverse Mercator (UTM) coordinates. Brief descriptions of bedrock samples are also included. Rocks analyzed are mostly sandstone,...
