Simulation of ground-water flow in the Vevay Township area, Ingham County, Michigan
Carol L. Luukkonen, Andreanne Simard
2004, Open-File Report 2004-1270
Ground water is the primary source of water for domestic, public-supply, and industrial use within the Tri-County region that includes Clinton, Eaton, and Ingham Counties in Michigan. Because of the importance of this ground-water resource, numerous communities, including the city of Mason in Ingham County, have begun local Wellhead Protection...
Chloroethene biodegradation potential, ADOT/PF Peger Road Maintenance Facility, Fairbanks, Alaska
Paul M. Bradley, Frances H. Chapelle
2004, Open-File Report 2004-1428
A series of 14C-radiotracer-based microcosm experiments were conducted to assess: 1) the extent, rate and products of microbial dechlorination of trichloroethene (TCE), cis-dichloroethene (cis-DCE) and vinyl chloride (VC) in sediments at the Peger Road site; 2) the effect of three electron donor amendments (molasses, shrimp and crab chitin, and 'Hydrogen...
An autonomous, electromagnetic seepage meter to study coastal groundwater/surface-water exchange
Peter W. Swarzenski, Matt Charette, Christian D. Langevin
2004, Open-File Report 2004-1369
The bi-directional exchange of groundwater with coastal surface waters may influence not only coastal-water and geochemical budgets, but may also impact and direct coastal ecosystem change. For example, the widespread discharge of nutrient-enriched submarine groundwater into an estuary or lagoon may contribute directly to the onset and duration of eutrophication,...
An operation manual for a time-series, storm-activated suspended sediment sampler deployed in the coastal ocean: function, maintenance, and testing procedures
Richard R. Rendigs, Michael H. Bothner
2004, Open-File Report 2004-1443
This manual describes the operation and testing procedures for two models of a multi-port suspended sediment sampler that are moored in the coastal ocean and that collect samples on a programmable time schedule that can be interrupted to collect during a storm. The ability to sense and collect samples before,...
An overview of urban stormwater-management practices in Miami-Dade County, Florida
David A. Chin
2004, Open-File Report 2004-1346
Agencies with jurisdiction over stormwater-management systems in Miami-Dade County, Florida, include the Miami-Dade Department of Environmental Resources Management (DERM), South Florida Water Management District (SFWMD), and Florida Department of Transportation (FDOT). These agencies are primarily concerned with minor drainage systems that handle runoff from storms with return periods of 10...
Immunoassay screening of sediment cores for polychlorinated biphenyls, Devil's Swamp Lake near Baton Rouge, Louisiana, 2004
Peter C. Van Metre, Jennifer T. Wilson
2004, Open-File Report 2004-1397
Devil’s Swamp Lake near Baton Rouge, Louisiana, constructed by dredging in 1973 in Devil’s Swamp along the Mississippi River, is contaminated with polychlorinated biphenyls (PCBs). This study investigated the possible historical contribution of PCBs from a hazardous-chemical disposal facility by way of a wastewater drainage ditch that operated from 1971...
User's manual for the national water information system of the U.S. Geological Survey: Ground-water site-inventory system
Water Resources Division, U.S. Geological Survey
2004, Open-File Report 2004-1238
The Ground-Water Site-Inventory (GWSI) System is a ground-water data storage and retrieval system that is part of the National Water Information System (NWIS) developed by the U.S. Geological Survey (USGS). The NWIS is a distributed water database in which data can be processed over a network of workstations and file...
A preliminary assessment of geologic framework and sediment thickness studies relevant to prospective US submission on extended continental shelf
Deborah R. Hutchinson, Jonathan R. Childs, Erika Hammar-Klose, Shawn Dadisman, N. Terrence Edgar, Ginger A. Barth
2004, Open-File Report 2004-1447
Under the provisions of Articles 76 and 77 of the United Nations Convention on the Law of the Sea (UNCLOS), coastal States have sovereign rights over the continental shelf territory beyond 200-nautical mile (nm) from the baseline from which the territorial sea is measured if certain conditions are met regarding...
GPS-aided inertial technology and navigation-based photogrammetry for aerial mapping the San Andreas fault system
Richard D. Sanchez, Kenneth W. Hudnut
2004, Open-File Report 2004-1389
Aerial mapping of the San Andreas Fault System can be realized more efficiently and rapidly without ground control and conventional aerotriangulation. This is achieved by the direct geopositioning of the exterior orientation of a digital imaging sensor by use of an integrated Global Positioning System (GPS) receiver and an Inertial...
Channel-morphology data for the Tongue River and selected tributaries, southeastern Montana, 2001-02
Katherine J. Chase
2004, Open-File Report 2004-1260
Coal-bed methane exploration and production have begun within the Tongue River watershed in southeastern Montana. The development of coal-bed methane requires production of large volumes of ground water, some of which may be discharged to streams, potentially increasing stream discharge and sediment load. Changes in stream discharge or sediment load...
Airborne Digital Sensor System and GPS-aided inertial technology for direct geopositioning in rough terrain
Richard D. Sanchez
2004, Open-File Report 2004-1391
High-resolution airborne digital cameras with onboard data collection based on the Global Positioning System (GPS) and inertial navigation systems (INS) technology may offer a real-time means to gather accurate topographic map information by reducing ground control and eliminating aerial triangulation. Past evaluations of this integrated system over relatively flat terrain...
Mineral production and mining trends for selected non-fuel commodities in Idaho and Montana, 1905-2001
Jeremy C. Larsen, Keith R. Long, Kenneth C. Assmus, Michael L. Zientek
2004, Open-File Report 2004-1414
Idaho and Montana state mining statistics were obtained from historical mineral production records and compiled into a continuous record from 1905 through 2001. To facilitate comparisons, the mineral production data were normalized by converting the units of measure to metric tons for all included commodities. These standardized statistical data include...
Is the extraction of thorium onto MnO2-coated filter cartridges uniform?
Peter W. Swarzenski, M. Baskaran
2004, Open-File Report 2004-1421
Large-volume (i.e., 102 - 103 L) seawater samples are traditionally required to study the partitioning of particle-reactive radionuclides between solution and size-fractionated particulate matter. One of the most frequently used methods to preconcentrate the short-lived isotopes of Th (234Th and 228Th) from such large volumes of water involves the effective...
