2002, Miscellaneous Field Studies Map 2398
INTRODUCTION The coastal cliffs along much of the central California coast are actively retreating. Large storms and periodic earthquakes are responsible for most of the documented seacliff slope failures. Long-term average erosion rates calculated for this section of coast (Moore and others, 1999) do not provide the spatial or temporal data...
Selected elements and organic chemicals in streambed sediment in the Salem area, Oregon, 1999
Dwight Q. Tanner
2002, Water-Resources Investigations Report 2002-4194
Analysis of streambed sediments in the Salem, Oregon, area showed anomalously large concentrations of some elements and organic chemicals, indicating contamination from anthropogenic and/or geologic sources. The streambed sediment sample from Clark Creek, an urban basin, had large concentrations of polycyclic aromatic hyrdocarbons (PAHs), organochlorines, cadmium, lead, and zinc. The...

2002, Open-File Report 2002-321
Large amounts of arsenic contamination, in excess of 2000 ppm, have been found in some residential surface soils in northern Denver, Colorado (USEPA, 1999). Associated with the arsenic are elevated levels of metals such as lead, cadmium and mercury. Potential sources of this contamination include waste from smelters in the...
A census of marine life: Unknowable or just unknown?

Hydrologic conditions in the Bill Williams River National Wildlife Refuge and Planet Valley, Arizona, 2000
Richard P. Wilson, Sandra J. Owen-Joyce
2002, Water-Resources Investigations Report 2002-4214
During a period of sustained base-flow conditions in the Bill Williams River below Alamo Dam in west central Arizona from March to July 2000, the channel of the river through Planet Valley was dry, and the water table sloped almost due west parallel to the main slope of the flood...

Occurrence and distribution of microbiological contamination and enteric viruses in shallow ground water in Baltimore and Harford counties, Maryland
William S.L. Banks, David A. Battigelli
2002, Water-Resources Investigations Report 2001-4216
The U.S. Geological Survey, in cooperation with the Maryland Department of the Environment and the Wisconsin State Laboratory of Hygiene, conducted a study to characterize the occurrence and distribution of viral contamination in small (withdrawing less than 10,000 gallons per day) public water-supply wells screened in the shallow aquifer in...
Feasibility of Estimating Constituent Concentrations and Loads Based on Data Recorded by Acoustic Instrumentation
A.C. Lietz
2002, Open-File Report 2002-285
The acoustic Doppler current profiler (ADCP) and acoustic Doppler velocity meter (ADVM) were used to estimate constituent concentrations and loads at a sampling site along the Hendry-Collier County boundary in southwestern Florida. The sampling site is strategically placed within a highly managed canal system that exhibits low and rapidly changing...

Comparison of vapor concentrations of volatile organic compounds with ground-water concentrations of selected contaminants in sediments beneath the Sudbury River, Ashland, Massachusetts, 2000
J.P. Campbell, F. P. Lyford, Richard E. Willey
2002, Open-File Report 2002-143
A mixed plume of contaminants in ground water, including volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and metals, near the former Nyanza property in Ashland, Massachusetts, discharges to the Sudbury River upstream and downstream of Mill Pond and a former mill raceway. Polyethylene-membrane vapor-diffusion (PVD) samplers were installed in...
Slope evolution at the Calvert Cliffs, Maryland — Measuring the change from eroding bluffs to stable slopes
Martha Herzog, Curtis E. Larsen, Michele McRae
2002, Open-File Report 2002-332
Despite a long history of geomorphic studies, it is difficult to ascertain the time required for slopes to change from near vertical exposures to relatively stable slopes due to inadequate age control. Actively eroding coastal bluffs along the western shore of the Chesapeake Bay provide a key for understanding the...

Water and sediment study of the Snake River watershed, Colorado, Oct. 9-12, 2001
D.L. Fey, S. E. Church, D.M. Unruh, D. J. Bove
2002, Open-File Report 2002-330
The Snake River watershed, located upstream from Dillon Reservoir in the central mountains of Colorado, has been affected by historical base-metal mining. Trout stocked in the Snake River for recreational purposes do not survive through the winter. Sediment cores analyzed by previous investigators from the reservoir revealed elevated concentrations of base metals and...
Surface Water Quality-Assurance Plan for the Alabama District of the U. S. Geological Survey
T. Scott Hedgecock, J. Leroy Pearman, Victor E. Stricklin
2002, Open-File Report 2002-305
The U.S. Geological Survey, Water Resources Division, has a policy that requires each District office to prepare a Surface Water Quality-Assurance Plan. The plan for each District describes the policies and procedures that ensure high quality in the collection, processing, analysis, computer storage, and publication of surface-water data. The Alabama...

Water Quality in the Mahoning River and Selected Tributaries in Youngstown, Ohio
Donald M. Stoeckel, S. Alex Covert
2002, Water-Resources Investigations Report 2002-4122
The lower reaches of the Mahoning River in Youngstown, Ohio, have been characterized by the Ohio Environmental Protection Agency (OEPA) as historically having poor water quality. Most wastewater-treatment plants (WWTPs) in the watershed did not provide secondary sewage treatment until the late 1980s. By the late 1990s, the Mahoning River...

2002, Oceanologica Acta (25) 193-197
Since its inception in 1999 the Ocean Biogeographic Information System (OBIS) has developed into an international science program as well as a globally distributed network of biogeographic databases. An OBIS portal at Rutgers University provides the links and functional interoperability among member database systems. Protocols and standards have been established...
Determination of isoxaflutole (balance) and its metabolites in water using solid phase extraction followed by high-performance liquid chromatography with ultraviolet or mass spectrometry
Chung-Ho Lin, Robert N. Lerch, E. Michael Thurman, Harold E. Garrett, Milon F. George
2002, Journal of Agricultural and Food Chemistry (50) 5816-5824
Balance (isoxaflutole, IXF) belongs to a new family of herbicides referred to as isoxazoles. IXF has a very short soil half-life (<24 h), degrading to a biologically active diketonitrile (DKN) metabolite that is more polar and considerably more stable. Further degradation of the DKN metabolite produces a nonbiologically active benzoic...
Effects of stress from mine drainage on diversity, biomass, and function of primary producers in mountain streams
Dev K. Niyogi, William M. Lewis Jr., Diane M. McKnight
2002, Ecosystems (5) 554-567
This paper proposes a hypothesis that relates biodi- versity, community biomass, and ecosystem func- tion to a gradient of stress. According to this hy- pothesis, biodiversity has a low threshold of response to stress, whereas biomass and function are stable or increase under low to moderate stress and decrease...
