Water-quality assessment of the White River Basin, Indiana: Analysis of selected information on nutrients, 1980-92 Water-quality assessment of the White River Basin, Indiana: Analysis of selected information on nutrients, 1980-92

Water-quality data from 23 surfacewater-quality monitoring sites operated by the Indiana Department of Environmental Management and streamflow data from 11 U.S. Geological Survey streamflow-gaging stations in the White River Basin were analyzed to determine recent (1981 90 water years) water-quality conditions, trends, and river loads for ammonia, nitrate, total nitrogen, and total...

Assessment of water quality at selected sites in the White River Basin, Indiana, 1993 and 1995 using biological indices Assessment of water quality at selected sites in the White River Basin, Indiana, 1993 and 1995 using biological indices

As part of the National Water Quality Assessment (NAWQA) Program, fish communities were sampled at 11 sites in the White River Basin, Indiana, in 1993 and 1995 to help determine water-quality conditions. Ninety-one species of fish with representatives from 18 families were collected in the basin. Total numbers of fish collected at every site increased between collection years. The Index...

Hydrogeology and simulated ground-water flow through the unconsolidated aquifers of northeastern St. Joseph County, Indiana Hydrogeology and simulated ground-water flow through the unconsolidated aquifers of northeastern St. Joseph County, Indiana

The U.S. Geological Survey investigated ground-water resources of northeastern St. Joseph County, Indiana, during 1990-93. The investigation included field measurements of water levels and numerical models of ground-water flow. This report documents results of that work and includes descriptions of (1) hydrogeologic framework, (2) water levels, (3) model sensitivity to variations in...

Occurrence of pesticides in ground water in the White River Basin, Indiana, 1994–95 Occurrence of pesticides in ground water in the White River Basin, Indiana, 1994–95

Pesticides (herbicides and insecticides) are used extensively in the White River Basin. Application of herbicides to corn and soybeans accounts for most of the use. The U.S. Geological Survey collected samples from four networks of monitoring wells in the White River Basin during 1994-95. The most frequently detected compounds in ground water were desethyl atrazine (a breakdown product...

Low-flow characteristics of Indiana streams Low-flow characteristics of Indiana streams

Knowledge of low-flow characteristics of streams is essential for management of water resources. Low-flow characteristics are presented for 229 continuous-record, streamflow-gaging stations and 285 partial-record stations in Indiana. Low- flow-frequency characteristics were computed for 210 continuous-record stations that had at least 10 years of record, and flow-duration curves were...

Comparison of gas chromatography/mass spectrometry and immunoassay techniques on concentrations of atrazine in storm runoff Comparison of gas chromatography/mass spectrometry and immunoassay techniques on concentrations of atrazine in storm runoff

Gas chromatography/mass spectrometry (GC/MS) and enzyme-linked immunosorbent assay (ELISA) techniques were used to measure concentrations of dissolved atrazine in 149 surface-water samples. Samples were collected during May 1992–September 1993 near the mouth of the White River (Indiana) and in two small tributaries of the river. GC/MS was performed on a Hewlett-Packard 5971 A, with...

Hydraulic conductivity of the streambed, east branch Grand Calumet River, northern Lake County, Indiana Hydraulic conductivity of the streambed, east branch Grand Calumet River, northern Lake County, Indiana

Horizontal and vertical hydraulic conductivity of the Streambed were estimated from results of hydraulic tests along four transects across the east branch Grand Calumet River in northern Lake County, Indiana. Tests were done in two types of temporary wells installed in the Streambed 2-inch-diameter wells that had a 1- or 2-foot length of wire-wrapped screen and 3-inch-diameter wells that...

A workbook for preparing surface water quality-assurance plans for districts of the U.S. Geological Survey, Water Resources Division A workbook for preparing surface water quality-assurance plans for districts of the U.S. Geological Survey, Water Resources Division

The U.S. Geological Survey, Water Resources Division, has a policy that each District Office is required to prepare a District 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 guidelines presented in this...

Effects of combined-sewer overflows and urban runoff on the water quality of Fall Creek, Indianapolis, Indiana Effects of combined-sewer overflows and urban runoff on the water quality of Fall Creek, Indianapolis, Indiana

In 1986, the U.S. Geological Survey and the Indianapolis Department of Public Works began a study to evaluate the effects of combined-sewer overflows and urban runoff discharging to Fall Geek on the White River. This report describes the effects of combined-sewer overflows and urban runoff on the water quality of Fall Creek during summer 1987 by comparing the water quality during base...

Water-quality assessment of the White River Basin, Indiana: Analysis of available information on pesticides, 1972-92 Water-quality assessment of the White River Basin, Indiana: Analysis of available information on pesticides, 1972-92

An analysis of historical pesticide data (1972-92) for the White River was conducted as part of the U.S. Geological Survey National Water-Quality Assessment Program. Data on the presence of pesticides in streams, bottom sediments, fish, and ground waters were examined. Results are interpreted with respect to spatial, seasonal, and streamflow effects. Concentrations of water-soluble...
