Tara Williams-Sether
1999, Fact Sheet 075-99
Unusual climatic and hydrologic conditions continue to affect the people and resources of North Dakota. Above-average precipitation during 1993-97 caused flooding in parts of North Dakota, and damage to crops, roads, and homes led to tremendous economic losses and increased personal stress for the people of the State. However, the...

Rice pesticide concentrations in the Colusa Basin Drain and the Sacramento River, California, 1990-1993
Kathryn L. Crepeau, Kathryn M. Kuivila
1999, Journal of Environmental Quality (29) 926-935
The pesticides molinate, thiobencarb, and carbofuran are applied to rice (Oryza sativa L.) fields in the Sacramento Valley, California, each year during April through June. These pesticides are of concern because of their adverse effects on water quality and their potential adverse effects on aquatic life. Therefore, the California Regional...

1999, Journal of Geophysical Research E: Planets (104) 8523-8553
Mars Pathfinder successfully landed at Ares Vallis on July 4, 1997, deployed and navigated a small rover about 100 m clockwise around the lander, and collected data from three science instruments and ten technology experiments. The mission operated for three months and returned 2.3 Gbits of data, including over 16,500...
Environmental characteristics and water quality of hydrologic benchmark network stations in the Eastern United States, 1963-95
M. Alisa Mast, John T. Turk
1999, Circular 1173-A
The information in this report was compiled to aid in the application and interpretation of historical water-quality data collected as part of the U.S. Geological Survey Hydrologic Benchmark Network program, which was established in 1963 to provide long-term measurements of streamflow and water quality in areas that are minimally affected...
Integrating surface and borehole geophysics in ground water studies: An example using electromagnetic soundings in south Florida
Frederick Paillet, Laura Hite, Matthew Carlson
1999, Journal of Environmental & Engineering Geophysics (4) 45-55
Time domain surface electromagnetic soundings, borehole induction logs, and other borehole logging techniques are used to construct a realistic model for the shallow subsurface hydraulic properties of unconsolidated sediments in south Florida. Induction logs are used to calibrate surface induction soundings in units of pore water salinity by correlating water...

Double-disk solid-phase extraction--Simultaneous cleanup and trace enrichment of herbicides and metabolites from environmental samples
Imma Ferrar, Damia Barcelo, E.M. Thurman
1999, Analytical Chemistry (71) 1009-1015
Phenylurea and triazine herbicides, including some metabolites, were isolated from water and soil extracts by solid-phase extraction using a layered system of two extraction disks, a method called double-disk solid-phase extraction. The first disk consisted of strong anion exchange (SAX) of 10-μm styrene divinylbenzene (SDB) particles embedded in Teflon, and...
Stable isotopes and mineral resource investigations in the United States
Robert R. Seal, II
1999, Report
The elements oxygen, hydrogen, sulfur, and carbon are important constituents of hydrothermal ore-forming systems and the weathering processes of mineral deposits in the surficial environment. They also play key roles in volcanic activity, ecosystem dynamics, climate change, and hydrologic and atmospheric processes. Therefore, study of the stable isotopes of these...
Environmental processes that affect mineral deposits in the eastern United States
Robert R. Seal, II
1999, Report
A thorough understanding of the environmental processes that affect mineral deposits and mine wastes has become increasingly important as the Nation wrestles with how to meet our current demand for metals without compromising the environment and how to mitigate the damage caused by the mining practices of previous generations. Regulatory...

The Brunswick and the underlying Lockatong Formations are comprised of littrifled Mesozoic sediments that constitute part of the Newark Basin in southeastern Pennsylvania (USA). These fractured rocks form an important regional aquifer that consists of gmdational sequences of shale, siltstone, and sandstone, with fluid transport occurring primarily in fractures. An...
