Revised Protocols for Sampling Algal, Invertebrate, and Fish Communities as Part of the National Water-Quality Assessment Program
Stephen R. Moulton II, Jonathan G. Kennen, Robert M. Goldstein, Julie A. Hambrook
2002, Open-File Report 2002-150
Algal, invertebrate, and fish communities are characterized as part of ecological studies in the U.S. Geological Survey.s National Water-Quality Assessment Program. Information from these ecological studies, together with chemical and physical data, provide an integrated assessment of water quality at local, regional, and national scales. Analysis and interpretation of water-quality...
Water-quality and ground-water hydrology of the Columbia/Eagle Bluffs Wetland Complex, Columbia, Missouri— 1992-99
Joseph M. Richards
2002, Water-Resources Investigations Report 2002-4227
In an effort to restore riverine wetlands along the Missouri River, the Missouri Department of Conservation constructed the 2,700-acre Eagle Bluffs Conservation Area. The primary water source for managing 1,200 wetland acres on the Eagle Bluffs Conservation Area is treated effluent received from a 91-acre constructed wastewater-treatment wetland operated by...
Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-A method supplement for the determination of Fipronil and degradates in water by gas chromatography/mass spectrometry
James F. Madsen, Mark W. Sandstrom, Steven D. Zaugg
2002, Open-File Report 2002-462
A method for the isolation and detemrination of fipronil and four of its degradates has been developed. This method adapts an analytical method created by the U.S. Geological Survey National Water Quality Laboratory in 1995 for the determination of a broad range of high-use pesticides typically found in filtered...
Atlas of natural hazards in the Hawaiian coastal zone
Charles H. Fletcher III, Eric E. Grossman, Bruce M. Richmond, Ann E. Gibbs
2002, IMAP 2761
The purpose of this report is to communicate to citizens and regulatory authorities the history and relative intensity of coastal hazards in Hawaii. This information is the key to the wise use and management of coastal resources. The information contained in this document,we hope,will improve the ability of Hawaiian citizens...
Twentieth century arroyo changes in Chaco Culture National Historical Park
Allen C. Gellis
2002, Water-Resources Investigations Report 2001-4251
Chaco Wash arroyo channel changes in the 20th century have become a major concern of the National Park Service. Several archeologic and cultural sites are located in the Chaco Wash corridor; thus, increased erosional activity of Chaco Wash, such as channel incision and increased meandering, may affect these sites. Through...
Map showing lava inundation zones for Mauna Loa, Hawai'i
F. A. Trusdell, P. Graves, C. R. Tincher
2002, Miscellaneous Field Studies Map 2401
The Island of Hawai‘i is composed of five coalesced basaltic volcanoes. Lava flows constitute the greatest volcanic hazard from these volcanoes. This report is concerned with lava flow hazards on Mauna Loa, the largest of the island shield volcanoes. Hilo lies 58 km from the summit of Mauna Loa, the...
Comparisons of water quality during various streamflow conditions in five streams in northern New Jersey, 1982-97
Kathryn Hunchak-Kariouk
2002, Water-Resources Investigations Report 2001-4249
Relations between water-quality and flow characteristics and the relative importance of constant (point sources and ground-water discharge) and intermittent (nonpoint storm runoff) sources were determined for eight water-quality stations located on the Flat Brook and the Delaware, Musconetcong, Whippany, and Saddle Rivers. Water-quality and streamflow data were categorized on the...
Results of Hydraulic Tests in Miocene Tuffaceous Rocks at the C-Hole Complex, 1995 to 1997, Yucca Mountain, Nye County, Nevada
Arthur L. Geldon, Amjad M.A. Umari, Michael F. Fahy, John D. Earle, James M. Gemmell, Jon Darnell
2002, Water-Resources Investigations Report 2002-4141
Four hydraulic tests were conducted by the U.S. Geological Survey at the C-hole complex at Yucca Mountain, Nevada, between May 1995 and November 1997. These tests were conducted as part of ongoing investigations to determine the hydrologic and geologic suitability of Yucca Mountain as a potential site for permanent underground...
The Cascadia Subduction Zone and related subduction systems: Seismic structure, intraslab earthquakes and processes, and earthquake hazards
Stephen H. Kirby, Kelin Wang, Susan Dunlop
2002, Open-File Report 2002-328
The following report is the principal product of an international workshop titled “Intraslab Earthquakes in the Cascadia Subduction System: Science and Hazards” and was sponsored by the U.S. Geological Survey, the Geological Survey of Canada and the University of Victoria. This meeting was held at the University of Victoria’s Dunsmuir...
Volatile organic compound and pesticide data in public water-supply reservoirs and wells, Texas, 1999-2001
Barbara Mahler, M.O. Gary, M.G. Canova, Eric W. Strom, Lynne Fahlquist, Michael E. Dorsey
2002, Open-File Report 2002-93
To provide data for the Texas Source-Water Assessment and Protection Program, the U.S. Geological Survey conducted a synoptic survey of 48 public water-supply reservoirs and 174 public water-supply wells during 1999–2001. The surface-water samples were analyzed for volatile organic compounds and soluble pesticides. The ground-water samples were analyzed for volatile...
Characterization of fractures and flow zones in a contaminated shale at the Watervliet Arsenal, Albany County, New York
John Williams, Frederick L. Paillet
2002, Open-File Report 2001-385
Flow zones in a fractured shale in and near a plume of volatile organic compounds at the Watervliet Arsenal in Albany County, N. Y. were characterized through the integrated analysis of geophysical logs and single- and cross-hole flow tests. Information on the fracture-flow network at the site was needed to...
