Quality-assurance design applied to an assessment of agricultural pesticides in ground water from carbonate bedrock aquifers in the Great Valley of eastern Pennsylvania Quality-assurance design applied to an assessment of agricultural pesticides in ground water from carbonate bedrock aquifers in the Great Valley of eastern Pennsylvania
Assessments to determine whether agricultural pesticides are present in ground water are performed by the Commonwealth of Pennsylvania under the aquifer monitoring provisions of the State Pesticides and Ground Water Strategy. Pennsylvania's Department of Agriculture conducts the monitoring and collects samples; the Department of Environmental Protection (PaDEP) Laboratory analyzes the...

Quality of wet deposition in the Grand Calumet River Watershed, northwestern Indiana, April 29, 1997–April 28, 1998 Quality of wet deposition in the Grand Calumet River Watershed, northwestern Indiana, April 29, 1997–April 28, 1998
The Grand Calumet River, in northwestern Indiana, drains a heavily industrialized area along the southern shore of Lake Michigan. Steel production and petroleum refining are two of the area’s predominant industries. High-temperature processes, such as fossil fuel combustion and steel production, release contaminants to the atmosphere that may result in wet deposition being a major...

A modern earth narrative: What will be the fate of the biosphere? A modern earth narrative: What will be the fate of the biosphere?
The modern Earth Narrative is the scientific description of the natural and human history of the Earth, and it is based on two fundamental concepts: Deep (or Geologic) Time and Biological Evolution. Changes in the Earth's biosphere and geosphere are discussed from the perspective of natural variability and impacts of the rapid increase in the human population. The failure of humans to...

The mountain that moved: geologic wonders of the George Washington and Jefferson National Forests The mountain that moved: geologic wonders of the George Washington and Jefferson National Forests
Prehistoric, giant landslides in Montgomery and Craig Counties, Va., in the Blacksburg/Wythe Ranger Districts of the Jefferson National Forest, are the largest known landslides in eastern North America and are among the largest in the world. One of the landslides is more than 3 miles long! The ancient, giant landslides extend for more than 20 miles along the eastern slope of Sinking...

Rapid activation of gill Na+, K+-ATPase the euryhaline teleost Fundulus heteroclitus Rapid activation of gill Na+, K+-ATPase the euryhaline teleost Fundulus heteroclitus
The rapid activation of gill Na+,K+-ATPase was analyzed in the mummichog (Fundulus heteroclitus) and Atlantic salmon (Salmo salar) transferred from low salinity (0.1 ppt) to high salinity (25–35 ppt). In parr and presmolt, Salmo salar gill Na+,K+-ATPase activity started to increase 3 days after transfer. Exposure of Fundulus heteroclitus to 35 ppt seawater (SW) induced a rise in gill Na+...

Habitats used by shortnose sturgeon two Massachusetts rivers, with notes on estuarine Atlantic sturgeon: A hierarchical approach Habitats used by shortnose sturgeon two Massachusetts rivers, with notes on estuarine Atlantic sturgeon: A hierarchical approach
Biotelemetry of shortnose sturgeon Acipenser brevirostrum and Atlantic sturgeon A. oxyrinchus oxyrinchus was used to study fish uses of habitat in several hierarchical classes in the Connecticut and Merrimack rivers. Hierarchical classes were geomorphological region (straight river run, run with an island, and river curve), river cross section (channel or shoal), and microhabitat (water...

Contaminant distribution and accumulation in the surface sediments of Long Island Sound Contaminant distribution and accumulation in the surface sediments of Long Island Sound
The distribution of contaminants in surface sediments has been measured and mapped as part of a U.S. Geological Survey study of the sediment quality and dynamics of Long Island Sound. Surface samples from 219 stations were analyzed for trace (Ag, Ba, Cd, Cr, Cu, Hg, Ni, Pb, V, Zn and Zr) and major (Al, Fe, Mn, Ca, and Ti) elements, grain size, and Clostridium perfringens spores...

Geochemical investigations by the U.S. Geological Survey on uranium mining, milling, and environmental restoration Geochemical investigations by the U.S. Geological Survey on uranium mining, milling, and environmental restoration
Recent research by the U.S. Geological Survey has characterized contaminant sources and identified important geochemical processes that influence transport of radionuclides from uranium mining and milling wastes. 1) Selective extraction studies indicated that alkaline earth sulfates and hydrous ferric oxides are important hosts of 226Ra in uranium mill tailings. The action of sulfate...
