Analysis of atrazine and four degradation products in the pore water of the vadose zone, central Indiana Analysis of atrazine and four degradation products in the pore water of the vadose zone, central Indiana

A new method is described for the analysis of atrazine and four of its degradation products (desethylatrazine, deisopropylatrazine, didealkylatrazine, and hydroxyatrazine) in water. This method uses solid- phase extraction on a graphitized carbon black cartridge, derivatization of the eluate with N-methyl-N-(tert-butyldimethylsilyl)trifluoroacetamide (MTBSTFA), and analysis by gas...

Suspended sediment in the Indiana Harbor Canal and the Grand Calumet River, northwestern Indiana, May 1996-June 1998 Suspended sediment in the Indiana Harbor Canal and the Grand Calumet River, northwestern Indiana, May 1996-June 1998

Suspended-sediment samples and streamflow data were collected from May 1996 through June 1998 at three sites in the Grand Calumet River Basin - Indiana Harbor Canal at East Chicago, the east branch of the Grand Calumet River at Gary, and the west branch of the Grand Calumet River at Hammond. Sample analysis allowed for retention of sediments of 0.0015 millimeters or larger.

Environmental Setting and Effects on Water Quality in the Great and Little Miami River Basins, Ohio and Indiana Environmental Setting and Effects on Water Quality in the Great and Little Miami River Basins, Ohio and Indiana

The Great and Little Miami River Basins drain approximately 7,354 square miles in southwestern Ohio and southeastern Indiana and are included in the more than 50 major river basins and aquifer systems selected for water-quality assessment as part of the U.S. Geological Survey's National Water-Quality Assessment Program. Principal streams include the Great and Little Miami Rivers in Ohio...

Benthic invertebrates and quality of streambed sediments in the White River and selected tributaries in and near Indianapolis, Indiana, 1994-96 Benthic invertebrates and quality of streambed sediments in the White River and selected tributaries in and near Indianapolis, Indiana, 1994-96

During this study, 369 benthic-invertebrate samples were collected at 21 sites and 33 streambed-sediment samples were collected at 14 sites to help develop and evaluate control strategies to mediate the impact of point and nonpoint sources of pollution on the White River and selected tributaries in and near Indianapolis, Indiana. Data analyses show that 124 taxa were identified and that...

Quality of wet deposition in the Grand Calumet River Watershed, northwestern Indiana, April 29, 1997–April 28, 1998 Quality of wet deposition in the Grand Calumet River Watershed, northwestern Indiana, April 29, 1997–April 28, 1998

The Grand Calumet River, in northwestern Indiana, drains a heavily industrialized area along the southern shore of Lake Michigan. Steel production and petroleum refining are two of the area’s predominant industries. High-temperature processes, such as fossil fuel combustion and steel production, release contaminants to the atmosphere that may result in wet deposition being a major...

Concentrations of Escherichia Coli in Streams in the Upper Wabash River Watershed in Indiana, June-September 1998 Concentrations of Escherichia Coli in Streams in the Upper Wabash River Watershed in Indiana, June-September 1998

Water samples collected from 46 stream sites in the Upper Wabash River Watershed from June through September 1998 were analyzed for concentrations of the bacteria Escherichia coli (E. coli). Each site was sampled five times in a 30-day period. Twenty-one sites were sampled during June and July, and 25 sites were sampled during August and September. The concentration of E. coli in 145 of...

In June 1992, a wet-deposition collection site was established at the Gary (Indiana) Regional Airport to monitor the quantity and chemical quality of wet deposition. During the first phase of sampling, 48 wet-deposition samples were collected between June 30, 1992, and August 31, 1993. A second phase of sampling began in October 1995. During the second phase of sampling, 40 wet...

Status and trends in suspended-sediment discharges, soil erosion, and conservation tillage in the Maumee River basin: Ohio, Michigan, and Indiana Status and trends in suspended-sediment discharges, soil erosion, and conservation tillage in the Maumee River basin: Ohio, Michigan, and Indiana

The relation of suspended-sediment discharges to conservation-tillage practices and soil loss were analyzed for the Maumee River Basin in Ohio, Michigan, and Indiana as part of the U.S. Geological Survey’s National Water-Quality Assessment Program. Cropland in the basin is the largest contributor to soil erosion and suspended-sediment discharge to the Maumee River and the river is the...

Water resources data, Ohio, water year 1999, Volume 1. Ohio River Basin excluding project data Water resources data, Ohio, water year 1999, Volume 1. Ohio River Basin excluding project data

Water-resources data for the 1999 water year for Ohio consist of records of stage, discharge, and water quality of streams; stage and contents of lakes and reservoirs; and water levels and water quality of ground-water wells. This report, in two volumes, contains records for water discharge at 120 gaging stations and 69 partial-record sites; water levels at 187 observation wells and 26...

Aquifer-system compaction and land subsidence: Measurements, analyses, and simulations – The Holly Site, Edwards Air Force Base, Antelope Valley, California Aquifer-system compaction and land subsidence: Measurements, analyses, and simulations – The Holly Site, Edwards Air Force Base, Antelope Valley, California

Land subsidence resulting from ground-water-level declines has long been recognized as a problem in Antelope Valley, California. At Edwards Air Force Base (EAFB), ground-water extractions have caused more than 150 feet of water-level decline, resulting in nearly 4 feet of subsidence. Differential land subsidence has caused sinklike depressions and earth fissures and has accelerated...

Summary and evaluation of pesticides in field blanks collected for the National Water-Quality Assessment Program, 1992-95 Summary and evaluation of pesticides in field blanks collected for the National Water-Quality Assessment Program, 1992-95

Field blanks are quality-control samples used to assess contamination in environmental water samples. Contamination is the unintentional introduction of a chemical (pesticides in this instance) into an environmental water sample from sources such as inadequately cleaned equipment, dirty hands, dust, rain, or fumes. Contamination causes a positive bias in analytical measurements that may...
