Effects of urbanization and long-term rainfall on the occurrence of organic compounds and trace elements in reservoir sediment cores, streambed sediment, and fish tissue from the Santa Ana River basin, California, 1998
Carmen A. Burton
2002, Water-Resources Investigations Report 2002-4175
Organcochlorine compounds, semivolatile-organic compounds (SVOC), and trace elements were analyzed in reservoir sediment cores, streambed sediment, and fish tissue in the Santa Ana River Basin as part of the U.S. Geological Survey's National Water-Quality Assessment Program. Three reservoirs were sampled in areas that have different degrees of urbanization. Streambed sediment...
Occurrence of antibiotics in water from fish hatcheries
Earl M. Thurman, Julie E. Dietze, Elisabeth A. Scribner
2002, Fact Sheet 120-02
The recent discovery of pharmaceuticals in streams across the United States (Kolpin and others, 2002) has raised the visibility and need for monitoring of antibiotics in the environment. Possible sources of antibiotics and other pharmaceuticals in streams may include fish hatcheries. This fact sheet presents the results from a preliminary...
Forecasting bacteria levels at bathing beaches in Ohio
Donna S. Francy, Robert A. Darner
2002, Fact Sheet 132-02
The U.S. Geological Survey developed models for predicting exceedance of the bathing-water standard for Escherichia coli (E. coli) at three Lake Erie beaches and one inland lake in Ohio. The statistical models were specific to each beach, and the best model for each beach was based on a unique combination...
Precipitation history of the Colorado Plateau region, 1900-2000

The Colorado Plateau covers 210,000 km 2 (130,000 mi 2) of Utah, Colorado, New Mexico, and Arizona. Management of this region?s resources requires an understanding of how its climate has varied in the past and may change in the near future. Recent studies by U.S. Geological Survey (USGS) and other...
Effects of wildfire on the hydrology of Frijoles and Capulin canyons in and near Bandelier National Monument, New Mexico

2002, Fact Sheet 141-02
In June 1977, the La Mesa wildfire burned 15,270 acres in and near Frijoles Canyon in Bandelier National Monument (BNM) and the adjacent Santa Fe National Forest, New Mexico. In April 1996, the Dome wildfire in BNM burned 16,516 acres in and near Capulin Canyon and the surrounding Dome Wilderness area. Both Frijoles and Capulin Canyon watersheds are characterized by archeological...

2002, Water-Resources Investigations Report 2001-4121
The U.S. Geological Survey, in cooperation with the U.S. Army Corps of Engineers, collected and analyzed flow data in combined sewer systems in Riverside and Evanston, northeastern Illinois, from March 1997 to December 1999. Continuous 2- and 5-minute stage and velocity data were collected during surcharged and nonsurcharged conditions at...
Bed-material entrainment potential, Roaring Fork River at Basalt, Colorado
John G. Elliott
2002, Water-Resources Investigations Report 2002-4223
The Roaring Fork River at Basalt, Colorado, has a frequently mobile streambed composed of gravel, cobbles, and boulders. Recent urban and highway development on the flood plain, earlier attempts to realign and confine the channel, and flow obstructions such as bridge openings and piers have altered the hydrology, hydraulics, sediment...
Mount Mazama and Crater Lake: Growth and destruction of a Cascade volcano
Edward P. Klimasauskas, Charles R. Bacon, Jim Alexander
2002, Fact Sheet 092-02
For more than 100 years, scientists have sought to unravel the remarkable story of Crater Lake’s formation. Before Crater Lake came into existence, a cluster of volcanoes dominated the landscape. This cluster, called Mount Mazama (for the Portland, Oregon, climbing club the Mazamas), was destroyed during an enormous explosive eruption...
Assessment of possible sources of microbiological contamination and water-quality characteristics of the Jacks Fork, Ozark National Scenic Riverways, Missouri — Phase II
Jerri V. Davis, Joseph M. Richards
2002, Water-Resources Investigations Report 2002-4209
In 1998, an 8-mile reach of the Jacks Fork was included on Missouri's list of impaired waters as required by Section 303(d) of the Federal Clean Water Act. The identified pollutant on the Jacks Fork was fecal coliform bacteria. Potential sources of fecal contamination to the Jacks Fork include a...
Modeling GPR data to interpret porosity and DNAPL saturations for calibration of a 3-D multiphase flow simulation
Kristen W. Sneddon, Michael H. Powers, Raymond H. Johnson, Eileen P. Poeter
2002, Open-File Report 2002-451
Dense nonaqueous phase liquids (DNAPLs) are a pervasive and persistent category of groundwater contamination. In an effort to better understand their unique subsurface behavior, a controlled and carefully monitored injection of PCE (perchloroethylene), a typical DNAPL, was performed in conjunction with the University of Waterloo at Canadian Forces Base Borden...
Using dye-tracing and chemical analyses to determine effects of a wastewater discharge to Jam Up Creek on water quality of Big Spring, southeastern Missouri, 2001
Jeffrey L. Imes, Brian S. Fredrick
2002, Fact Sheet 103-02
On July 5, 2001, approximately 50,000 gallons of partially treated wastewater was accidentally discharged from the Mountain View wastewater-treatment plant in Howell County, Missouri, into nearby Jam Up Creek. The creek is a tributary of the Jacks Fork, a recreational stream administered by the National Park Service (NPS) as part...
Escherichia coli in the swash zone at four Ohio bathing beaches
Donna S. Francy, Amie M. Gifford
2002, Fact Sheet 134-02
The zone of the shoreline that is constantly washed by waves or tides, called the swash zone, is an attractive recreational area, especially for children who play in the sand. The swash zone, however, has been suggested as a possible habitat for waterborne disease-causing microorganisms (pathogens). The spaces between the...
