Hydrogeology of south-central St. Croix, U.S. Virgin Islands
R. P. Graves
1995, Water-Resources Investigations Report 93-4162
The subsurface geology of south-central St. Croix consists of alluvium and underlying carbonate rocks. The alluvial deposits consist of sand and gravel with cobbles and boulders and, locally, thin lenses of silt and clay. The carbonate rocks consist of the Oligocene to Middle Miocene age Jealousy formation, the Miocene and...
A feasibility study to estimate minimum surface-casing depths of oil and gas wells to prevent ground-water contamination in four areas of western Pennsylvania
T. F. Buckwalter, P. J. Squillace
1995, Water-Resources Investigations Report 87-4136
Hydrologic data were evaluated from four areas of western Pennsylvania to estimate the minimum depth of well surface casing needed to prevent contamination of most of the fresh gr6unct-water resources by oil and gas wells. The areas are representative of the different types of oil and gas activities and of...

Geometry of sorbed arsenate on ferrihydrite and crystalline FeOOH: Re-evaluation of EXAFS results and topological factors in predicting sorbate geometry, and evidence for monodentate complexes
Glenn A. Waychunas, James A. Davis, Christopher C. Fuller
1995, Geochimica et Cosmochimica Acta (59) 3655-3661
Manceau's (1995) reinterpretation of some of our EXAFS results (Waychunas et al., 1993) has been analyzed using both old and newly collected data in an attempt to clarify the nature of proposed monodentate and edge-sharing bidentate arsenate complexes on the ferrihydrite surface. It is shown that EXAFS analysis utilizing data...
Combined use of groundwater dating, chemical, and isotopic analyses to resolve the history and fate of nitrate contamination in two agricultural watersheds, Atlantic coastal plain, Maryland
J.K. Böhlke, J. M. Denver
1995, Water Resources Research (31) 2319-2339
The history and fate of groundwater nitrate (NO3−) contamination were compared in 2 small adjacent agricultural watersheds in the Atlantic coastal plain by combined use of chronologic (CCl2F2, 3H), chemical (dissolved solids, gases), and isotopic (δ15N,δ13C, δ34S) analyses of recharging groundwaters, discharging groundwaters, and surface waters. The results demonstrate the interactive...

Effects of two contrasting agricultural land uses on shallow groundwater quality in the San Joaquin Valley, California; design and preliminary interpretation
N. M. Dubrovsky, Karen R. Burow, Jo Ann M. Gronberg
1995, Open-File Report 95-286
From 1992 through 1994, the San Joaquin-Tulare Basins Study team of the USGS National Water Quality Assessment program investigated the occurrence and distribution of water quality constituents in shallow groundwater underlying two areas of different agricultural land uses: almond orchards and vineyards. The study was restricted to the alluvial fans...

1995, Water-Resources Investigations Report 94-4081
Sediment resuspension was studied in Old Tampa BaY, the northwestern subembayment of Tampa Bay, and in Hillsborough Bay, the northeastern subembayment of Tampa Bay located along the coast of west-central Florida. Electromagnetic current meters, optical backscatterance sensors, and water samples were used to collect sediment resuspension data at several study...

1995, Water-Resources Investigations Report 92-4154
Stratified-drift aquifers discontinuously underlie 121 mi2 (square miles) of the Contoocook River Basin, which has a total drainage area of 776 mi2. Maps of these aquifers, showing water-table configurations, saturated thicknesses, and transmissivities were prepared from well and test-hole data and seismic-refraction profiles. The distribution of stratified-drift aquifers is largely...
