Relation between land use and ground-water quality in the upper glacial aquifer in Nassau and Suffolk Counties, Long Island, New York
D. A. Eckhardt, W.J. Flipse Jr., E. T. Oaksford
1989, Water-Resources Investigations Report 86-4142
The chemical quality of groundwater in the upper glacial (water-table) aquifer beneath the 10 types of land-use areas of Nassau and Suffolk Counties, NY was examined to evaluate the effect of human activities on groundwater. The highest median chloride and total dissolved-solids concentrations were found in wells in high-density residential...
Sedimentary structures and textures of Rio Orinoco channel sands, Venezuela and Colombia
Edwin Dinwiddie McKee
1989, Water Supply Paper 2326-B
Most sedimentary structures represented in sand bodies of the Rio Orinoco are tabular-planar cross-strata which, together with some wedge-planar cross-strata, are the products of sand-wave deposition. Locally, in areas of river meander where point bars characteristically form, trough structures forming festoon patterns are numerous. At a few localities, sets of...
Water resources data for Mississippi, water year 1988
E.J. Tharpe, M.L. Plunkett, F. Morris, W. T. Oakley
1989, Water Data Report MS-88-1
Water resources data for the 1988 water year for Mississippi consist of records of stage, discharge, and water quality of streams; stage, and water quality of lakes and reservoirs; and water levels and water quality of ground-water wells. This report contains records of water discharge at 70 gaging stations; stage...
Water resources data, Puerto Rico and the U.S. Virgin Islands, water year 1987
R. E. Curtis Jr., Zaida Aquino, P.L. Diaz, Ricardo Vachier
1989, Water Data Report PR-87-1
Water-resources data for surface-water, quality-of-water, and ground-water records for the 1987 water year for Puerto Rico and the U.S Virgin Islands, consists of records of discharge, water quality of streams, and water levels of wells. This report contains discharge records for 49 streamflow-gaging stations, and 1 crest-stage, partial-record streamflow stations;...
Compilation of geohydrologic data collected as part of the areal appraisal of ground-water resources near Branson, Missouri
J. L. Imes
1989, Open-File Report 89-401
A rapidly developing retirement community and tourist industry in the Branson, Missouri area has created an increased demand for potable water, especially in the summer months. The rapid pace of residential and business expansion has created concerns regarding the future groundwater availability and quality. Water levels measured in the Ozark...
Maps showing trace-element geochemistry of the Sangre de Cristo Wilderness Study Area, south-central Colorado
David R. Zimbelman
1989, Miscellaneous Field Studies Map 1635-C
A trace-element geochemical study of the Sangre de Cristo Wilderness Study Area included the collection of 710 heavy-mineral-concentrate samples, 767 minus-80 mesh stream-sediment samples, and 145 rock samples.  All samples were analyzed for 31 elements by semiquantitative emission-spectrographic methods, and some stream-sediment and rock samples were also analyzed for selected...
Summary and interpretation of geochemical maps for stream sediment and heavy mineral concentrate samples, Mount Hayes Quadrangle, eastern Alaska Range, Alaska
Gary C. Curtin, Richard B. Tripp, Warren J. Nokleberg
1989, Miscellaneous Field Studies Map 1996-B
This report and accompanying maps summarize the results of geochemical exploration studies in the Mount Hayes quadrangle, Alaska. This is one of a series of maps and reports on the geological, geochemical, and geophysical studies of the quadrangle prepared as part of the Alaskan Mineral Resource Assessment Program (AMRAP) of...
Triassic-Jurassic stratigraphy of the Culpeper and Barboursville basins, Virginia and Maryland
K. Y. Lee, A.J. Froelich
1989, Professional Paper 1472
The presence of Late Triassic and Early Jurassic spores and pollen throughout an exposed stratigraphic section has enabled the systematic palynofloral zonation of the entire Culpeper Group, supported in places by characteristic fish zones. Strata of the Culpeper Group range in age from the Late Triassic to the Early Jurassic....
