Biological and associated water-quality data for lower Olmos Creek and upper San Antonio River, San Antonio, Texas, March-October 1990
Biological and associated water-quality data were collected from lower Olmos Creek and upper San Antonio River in San Antonio, Texas, during March-October 1990, the second year of a multiyear data-collection program. The data will be used to document water-quality conditions prior to implementation of a proposal to reuse treated wastewater to irrigate city properties in Olmos Basin and Brackenridg

Hydrologic data from the lower Cedar River Basin, Iowa, 1989-91
Hydrologic data were collected from May 1989 through July 1991 from the Cedar River and the adjacent alluvial aquifer. The data were collected during various flow regimes of the river to evaluate the movement of agricultural chemicals between surface water and ground water. Water-quality samples from 34 surface-water sites and 95 ground-water sites were analyzed for 11 herbicides, 2 dealkylated at

U.S. Geological Survey nutrient preservation experiment: Nutrient concentration data for surface-, ground-, and municipal-supply water samples and quality-assurance samples
This report is a compilation of analytical results from a study conducted at the U.S. Geological Survey, National Water Quality Laboratory (NWQL) in 1992 to assess the effectiveness of three field treatment protocols to stabilize nutrient concentra- tions in water samples stored for about 1 month at 4C. Field treatments tested were chilling, adjusting sample pH to less than 2 with sulfuric acid an

Simulation of hydrodynamics and solute transport in the Pamlico River estuary, North Carolina
An investigation was conducted to characterize flow, circulation, and solute transport in the Pamlico River estuary, North Carolina. The study included a detailed field-measurement program and the calibration, validation, and application of a physically realistic numerical model of hydro- dynamics and transport. Water level, salinity, water temperature, wind speed and direction, and current data w

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of organochlorine pesticides and polychlorinated biphenyls in bottom sediment by dual capillary-column gas chromatography with electron-capture detection
A method for the determination of 30 individual organochlorine pesticides, total toxaphene, and total polychlorinated biphenyls (PCBs) in bottom sediment is described. The method isolates the pesticides and PCBs by solvent extraction with dichlorobenzene, removes inorganic sulfur, large naturally occurring molecules, and other unwanted interferences by gel permeation chromatography, and further cl

Water-level altitudes 1995 and water-level changes 1990-95 and 1994-95 in the Chicot and Evangeline aquifers, Fort Bend County and adjacent areas, Texas
This report is one in an annual series of reports that depicts altitudes of water levels and water-level changes since 1990 in the Chicot and Evangeline aquifers in Fort Bend Subsidence District, presents the approximate altitude of water levels (figs. 1, 4), January-February 1995, and approximate changes in water levels (figs. 2, 3, 5, 6), 1990-95 and 1994-95, in each of the aquifers. The most r

Altitude and configuration of the potentiometric surface in part of lower Providence Township, Montgomery County, Pennsylvania, May and June 1994
A map showing ground-water levels in part of Lower Providence Township, Montgomery County, Pennsylvania, was constructed from water levels measured in 62 wells from May and June 1994. Observed water-level altitudes range from 60 feet above sea level near the Betzwood Picnic Area to 187 feet above sea level near the intersection of Egypt Road and Rittenhouse Road in Lower Providence Township.

Geologic framework and hydrogeologic characteristics of the Edwards Aquifer recharge zone, Bexar County, Texas
In Bexar County, residential and commercial development on the Edwards aquifer recharge zone is increasing. The aquifer possibly can be contaminated by spills, leakage of hazardous materials, or runoff from the rapidly developing urban areas that surround, or are built on, the intensely faulted and fractured, karstic limestone outcrops characteristic of the recharge zone. Furthermore, some of the

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 flow with th

Water-quality assessment of the upper Snake River Basin, Idaho and western Wyoming — Environmental setting, 1980-92
The 35,800-square-mile upper Snake River
Basin is one of 20 areas studied as part of the
National Water-Quality Assessment (NAWQA)
Program of the U.S. Geological Survey. Objectives of NAWQA are to study ground- and
surface-water quality, biology, and their relations
to land-use activities. Major land and water uses
that affect water quality in the basin are irrigated
agriculture, grazing, a
