Variability of mercury concentrations in domestic well water, New Jersey Coastal Plain
Zoltan Szabo, Julia L. Barringer, Eric Jacobsen, Nicholas P Smith, Robert A Gallagher, Andrew Sites
2010, Conference Paper
Concentrations of total (unfiltered) mercury (Hg) exceed the Maximum Contaminant Level (2 µg/L) in the acidic water withdrawn by more than 700 domestic wells from the areally extensive unconfined Kirkwood-Cohansey aquifer system. Background concentrations of Hg generally are <0.01 µg/L. The source of the Hg contamination has been hypothesized to...
Quantification of surface water and groundwater flows to open‐ and closed‐basin lakes in a headwaters watershed using a descriptive oxygen stable isotope model
Edward G. Stets, Thomas C. Winter, Donald O. Rosenberry, Robert G. Striegl
2010, Water Resources Research (46)
Accurate quantification of hydrologic fluxes in lakes is important to resource management and for placing hydrologic solute flux in an appropriate biogeochemical context. Water stable isotopes can be used to describe water movements, but they are typically only effective in lakes with long water residence times. We developed a descriptive...

Summer M. Burdick, Scott P. VanderKooi
2010, Open-File Report 2010-1051
Lost River sucker (Deltistes luxatus) and shortnose sucker (Chasmistes brevirostris) were listed as endangered in 1988 for a variety of reasons including apparent recruitment failure. Upper Klamath Lake, Oregon, and its tributaries are considered the most critical remaining habitat for these two species. Age-0 suckers are often abundant in Upper...

Anthony J. Paulson, Morgan E. Keys, Kelly L. Scholting
2010, Open-File Report 2009-1285
Historical records of mercury contamination in dated sediment cores from Sinclair Inlet are coincidental with activities at the U.S. Navy Puget Sound Naval Shipyard; peak total mercury concentrations occurred around World War II. After World War II, better metallurgical management practices and environmental regulations reduced mercury contamination, but total mercury...

2010, Open-File Report 2010-1034
High-flow experiments (HFEs) from Glen Canyon Dam are primarily intended to conserve fine sediment and improve habitat conditions for native fish in the Colorado River as it flows through Grand Canyon National Park, Arizona. These experimental flows also have the potential to affect the rainbow trout (Oncorhynchus mykiss) population in...
An integrated perspective of the continuum between earthquakes and slow-slip phenomena
Zhigang Peng, Joan Gomberg
2010, Nature Geoscience (3) 599-607
The discovery of slow-slip phenomena has revolutionized our understanding of how faults accommodate relative plate motions. Faults were previously thought to relieve stress either through continuous aseismic sliding, or as earthquakes resulting from instantaneous failure of locked faults. In contrast, slow-slip events proceed so slowly that slip is limited and...

Molybdenum-A Key Component of Metal Alloys
S.J. Kropschot
2010, Fact Sheet 2009-3106
Molybdenum, whose chemical symbol is Mo, was first recognized as an element in 1778. Until that time, the mineral molybdenite-the most important source of molybdenum-was believed to be a lead mineral because of its metallic gray color, greasy feel, and softness. In the late 19th century, French metallurgists discovered that...
