Pond-aquifer interaction at South Pond of Lake Cochituate, Natick, Massachusetts
Paul J. Friesz, Peter E. Church
2001, Water-Resources Investigations Report 2001-4040
A U.S. Army facility on a peninsula in South Pond of Lake Cochituate was designated a Superfund site by the U.S. Environmental Protection Agency in 1994 because contaminated ground water was detected at the facility, which is near the Natick Springvale public-supply wellfield. The interaction between South Pond and the...
Source identification and fish exposure for polychlorinated biphenyls using congener analysis from passive water samplers in the Millers River basin, Massachusetts
John A. Colman
2001, Water-Resources Investigations Report 2000-4250
Measurements of elevated concentrations of polychlorinated biphenyls (PCBs) in fish and in streambed sediments of the Millers River Basin, Massachusetts and New Hampshire, have been reported without evidence of the PCB source. In 1999, an investigation was initiated to determine the source(s) of the elevated PCB concentrations observed in fish...

Gregory F. Ulmishek
2001, Bulletin 2201-D
The triangular-shaped North Ustyurt basin is located between the Caspian Sea and the Aral Lake in Kazakhstan and Uzbekistan and extends offshore both on the west and east.

2001, Water-Resources Investigations Report 2001-4018
Water samples collected from 58 surface- water sites in the Kankakee and Lower Wabash River Watersheds from June through September 1999 were analyzed for concentrations of Escherichia coli bacteria. Each sitewas sampled five times in a 30-day period. Twentynine sites were sampled during June and July, and 29 different sites...
Continental shelf GIS for the Monterey Bay National Marine Sanctuary
Florence L. Wong, Stephen L. Eittreim
2001, Open-File Report 2001-179
A marine sanctuary is an environment where the interests of science and society meet. Sanctuary managers need access to the best scientific data available that describe the environment and environmental processes in sanctuaries. Seafloor mapping and sampling in the Monterey Bay National Marine Sanctuary have revealed new details about the...
Hydrogeology and ground-water flow in the Memphis and Fort Pillow aquifers in the Memphis area, Tennessee
J. V. Brahana, R. E. Broshears
2001, Water-Resources Investigations Report 89-4131
On the basis of known hydrogeology of the Memphis and Fort Pillow aquifers in the Memphis area, a three-layer, finite-difference numerical model was constructed and calibrated as the primary tool to refine understanding of flow in the aquifers. The model was calibrated and tested for accuracy in simulating measured heads...

Barry P. Baldigo, T.P. Baudanza
2001, Water-Resources Investigations Report 99-4237
Copper-avoidance tests and acute-toxicity (mortality) tests on hatchery-reared, young-of- the-year brown trout (salmo trutta) were conducted with water from West Branch Reservoir to assess the avoidance response to copper sulfate treatment, which is used occasionally by New York City Department of Environmental Protection to decrease phytoplankton populations in the reservoir....
Estimated recharge to the Madison and Minnelusa aquifers in the Black Hills area, South Dakota and Wyoming, water years 1931-98
Janet M. Carter, D.G. Driscoll, G.R. Hamade
2001, Water-Resources Investigations Report 2000-4278
The Madison and Minnelusa aquifers are two of the most important aquifers in the Black Hills area. Long-term estimates of recharge to the Madison and Minnelusa aquifers are important for managing the water resources in the Black Hills area. Thus, annual recharge from streamflow losses and infiltration of precipitation on...
Maps showing the development of the Pu‘u ‘Ö‘ö-Küpaianaha flow field, June 1984-February 1987, Kïlauea Volcano, Hawaii
Christina Heliker, George E. Ulrich, Sandy C. Margriter, John P. Hoffmann
2001, IMAP 2685
The Pu'u 'O'o - Kupaianaha eruption on the middle east rift zone of Kilauea began in January 1983 with intermittent activity along several fissures. By June 1983, the eruption had localized at the Pu'u 'O'o vent, and the activity settled into an increasingly regular pattern of brief eruptive episodes characterized...
Droughts, epic droughts and droughty centuries - lessons from a California paleoclimatic record: a PACLIM 2001 meeting report
M. D. Dettinger
2001, Interagency Ecological Program Newsletter (14) 51-53
During the early 1990s (but echoing studies by S.T. Harding at the University of California, from as early as the 1930s), several lines of paleoclimate evidence in and around the Sierra Nevada Range have provided the water community in California with some real horror stories. By studying ancient tree stumps...
Analysis of borehole-radar reflection logs from selected HC boreholes at the Project Shoal area, Churchill County, Nevada
J.W. Lane Jr., P. K. Joesten, G.M. Pohll, Todd Mihevic
2001, Water-Resources Investigations Report 2001-4014
Single-hole borehole-radar reflection logs were collected and interpreted in support of a study to characterize ground-water flow and transport at the Project Shoal Area (PSA) in Churchill County, Nevada. Radar logging was conducted in six boreholes using 60-MHz omni-directional electric-dipole antennas and a 60-MHz magnetic-dipole directional receiving antenna.Radar data from...
Estimates of mountain-front streamflow available for potential recharge to the Tularosa Basin, New Mexico
Scott D. Waltemeyer
2001, Water-Resources Investigations Report 2001-4013
Streamflow in the Tularosa Basin, New Mexico, infiltrates into alluvial-basin aquifers at or near mountain fronts. Streamflow at or near mountain fronts is a substantial component of potential recharge to these aquifers. Streamflow response from precipitation differs substantially between the streams draining the Sacramento Mountains on the eastern side of...
Hydrogeologic framework and geochemistry of the intermediate aquifer system in parts of Charlotte, De Soto, and Sarasota counties, Florida
A. E. Torres, L. A. Sacks, D. K. Yobbi, L. A. Knochenmus, B. G. Katz
2001, Water-Resources Investigations Report 2001-4015
The hydrogeologic framework underlying the 600-square-mile study area in Charlotte, De Soto, and Sarasota Counties, Florida, consists of the surficial aquifer system, the intermediate aquifer system, and the Upper Floridan aquifer. The hydrogeologic framework and the geochemical processes controlling ground-water composition were evaluated for the study area. Particular emphasis was...

2001, Water-Resources Investigations Report 2000-4040
The Neversink Watershed Study was initiated in 1991 to develop an understanding of the key natural processes that control water quality within the forested, 166 km 2 (64 mi 2), Neversink River watershed; part of the New York City drinking water supply system, in the Catskill Mountain region of New...
Hydrogeology and extent of saltwater intrusion of the Great Neck peninsula, Great Neck, Long Island, New York
Frederick Stumm
2001, Water-Resources Investigations Report 99-4280
Great Neck, a peninsula, in the northwestern part of Nassau County, N.Y., is underlain by unconsolidated deposits that form a sequence of aquifers and confining units. Seven public-supply wells have been affected by the intrusion of saltwater from the surrounding embayments (Little Neck Bay, Long Island Sound, Manhasset Bay). Fifteen...
Analytical versus numerical estimates of water-level declines caused by pumping, and a case study of the Iao Aquifer, Maui, Hawaii
Delwyn S. Oki, William Meyer
2001, Water-Resources Investigations Report 2000-4244
Comparisons were made between model-calculated water levels from a one-dimensional analytical model referred to as RAM (Robust Analytical Model) and those from numerical ground-water flow models using a sharp-interface model code. RAM incorporates the horizontal-flow assumption and the Ghyben-Herzberg relation to represent flow in a one-dimensional unconfined aquifer that contains...

Gregory E. Schwarz, Richard A. Smith, Richard B. Alexander, John R. Gray
2001, Conference Paper, Proceedings of the Seventh Federal Interagency Sedimentation Conference, March 25 to 29, 2001, Reno, Nevada
Suspended sediment has long been recognized as an important contaminant affecting water resources. Besides its direct role in determining water clarity, bridge scour and reservoir storage, sediment serves as a vehicle for the transport of many binding contaminants, including nutrients, trace metals, semi-volatile organic compounds, a nd numerous pesticides (U.S....
