Effects of highway-deicer application on ground-water quality in a part of the Calumet Aquifer, northwestern Indiana
Lee R. Watson, E. Randall Bayless, Paul M. Buszka, John T. Wilson
2002, Water-Resources Investigations Report 2001–4260
The effects of highway-deicer application on ground-water quality were studied at a site in northwestern Indiana using a variety of geochemical indicators. Site characteristics such as high snowfall rates; large quantities of applied deicers; presence of a high-traffic highway; a homogeneous, permeable, and unconfined aquifer; a shallow water table; a...
Ground-water quality and effects of poultry confined animal feeding operations on shallow ground water, upper Shoal Creek basin, Southwest Missouri, 2000
Douglas N. Mugel
2002, Water-Resources Investigations Report 2002-4125
Forty-seven wells and 8 springs were sampled in May, October, and November 2000 in the upper Shoal Creek Basin, southwest Missouri, to determine if nutrient concentrations and fecal bacteria densities are increasing in the shallow aquifer as a result of poultry confined animal feeding operations (CAFOs). Most of the land use in...

Pesticides and their breakdown products in Lake Waxahachie, Texas, and in finished drinking water from the lake
Patricia B. Ging
2002, Fact Sheet 032-02
Since 1991, the U.S. Geological Survey (USGS) National Water-Quality Assessment (NAWQA) Program has collected pesticide data from streams and aquifers throughout the Nation (Gilliom and others, 1995). However, little published information on pesticides in public drinking water is available. The NAWQA Program usually collects data on the sources of drinking...

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...

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...
Map Showing Seacliff Response to Climatic and Seismic Events, Depot Hill, Santa Cruz County, California
Cheryl J. Hapke, Bruce M. Richmond, Mimi M. D’Iorio
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...

Cheryl J. Hapke, Bruce M. Richmond, Mimi M. D’Iorio
2002, Miscellaneous Field Studies Map 2400
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 sea cliff slope failures. Long-term average erosion rates calculated for this section of coast do not provide the spatial or temporal data resolution necessary to...

2002, IMAP 2747
Introduction The Magellan spacecraft orbited Venus from August 10, 1990, until it plunged into the Venusian atmosphereon October 12, 1994. Magellan had the objectives of: (1) improving knowledge of the geologic processes, surface properties, and geologic history of Venus by analysis of surface radar characteristics, topography, and morphology and (2) improving...
Carbon budget for a subtropical seagrass dominated coastal lagoon: How important are seagrasses to total ecosystem net primary production?
James Kaldy, Christopher P. Onuf, Peter Eldridge, Luis A. Cifuentes
2002, Estuaries (25) 528-539
It has been assumed that because seagrasses dominate macrophyte biomass in many estuaries they also dominate primary production. We tested this assumption by developing three carbon budgets to examine the contribution of autotrophic components to the total ecosystem net primary production (TENPP) of Lower Laguna Madre, Texas. The first budget...

Development of a stream habitat index for the Northern Lakes and Forest Ecoregions
Robert M. Goldstein, Lizhu Wang, Thomas P. Simon, Paul M. Stewart
2002, North American Journal of Fisheries Management (22) 452-464
Physical habitat was quantified in 105 randomly selected streams across the Northern Lakes and Forests Ecoregion during 1998 and 1999 to develop a stream habitat index for the region. Physical habitat measures (106) were classified into four groups: substrate, instream cover, riparian zone–land use, and geomorphology–hydrology. Variable reduction procedures yielded...
