Mantle helium in the groundwater of the Mirror Lake Basin, New Hampshire, USA, 1994
Helium isotope analyses of ground waters from the Mirror Lake drainage basin in central New Hampshire (USA) show helium in excess of air-saturated water by up to 200x. The freon ages of these waters are younger than 50 years, consistent with the local hydrology. This excess helium has an isotope ratio of ^3He/^4He = 1.65 ± 0.10 x 10^(-6). It is shown that this component cannot be the result of cos

Plan of study to determine the effect of changes in herbicide use on herbicide concentrations in Midwestern streams, 1989-94
An approach was developed to determine if recent changes in the use of herbicides has affected herbicide concentrations in Midwestern streams. This approach also provides a plan to determine if the abnormally high rainfall and flooding in 1993 has an effect on nitrate concentrations in 1994 in streams that flooded in 1993. The approach involves sampling 53 stream sites, 50 of which were sampled in

Hydrologic data for the Big Spring basin, Clayton County, Iowa, water year 1991
Hydrologic data were collected in the Big Spring Basin located in Clayton County, Iowa, during the 1991 water year. The data were collected by the U.S. Geological Survey in cooperation with the Iowa Department of Natural Resources, Geological Survey Bureau, to provide information on variation and movement of agricultural chemicals in the hydrologic cycle in the basin. Precipitation, surface-water,

Water-quality data from continuously monitored sites in the Pamlico and Neuse River estuaries, North Carolina, 1991-92
Water-quality measurements were made at six sites in or near North Carolina?s Pamlico River estuary and at five sites in or near the Neuse River estuary. Measurements taken at 15-minute intervals included near-surface and near-bottom specific conductance; near-surface water temperature; and near-surface, mid-depth, and near-bottom dissolved-oxygen concentrations.
In the Pamlico River estuary, s

Lithologic descriptions of two cores and ground-water-quality data from five counties in the northeastern part of the coastal plain of South Carolina, 1988 and 1991
This report presents data collected as part of a hydrologic investigation of Darlington, Dillon, Florence, Marion, and Marlboro Counties in the northeastern part of the Coastal Plain of South Carolina. These data include lithologic descriptions of sediment recovered from two continuously cored boreholes and water-quality results for samples collected from 17 existing wells. One continuously cored

Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of antimony by automated-hydride atomic absorption spectrophotometry
The analysis of natural-water samples for antimony by automated-hydride atomic absorption spectrophotometry is described. Samples are prepared for analysis by addition of potassium and hydrochloric acid followed by an autoclave digestion. After the digestion, potassium iodide and sodium borohydride are added automatically. Antimony hydride (stibine) gas is generated, then swept into a heated quart

Flood of June 17, 1990, in the Clear Creek Basin, east-central Iowa
A water-surface-elevation profile for the flood of June 17, 1990, in the Clear Creek Basin, east-central Iowa, is given in this report. The maximum flood-peak discharge of 10,200 cubic feet per second for the streamflow-gaging station on Clear Creek near Coralville, Iowa (station number 05454300), occurred on June 17, 1990. This discharge was approximately equal to the 80-year recurrence-interval

Water-quality data for the South Umpqua River Basin, Oregon, 1990-92
Data are presented from a study of algal and nutrient dynamics in the South Umpqua River Basin in southwestern Oregon during summer, low-flow periods from September 1990 to October 1992. The study was done to assist local and state regulatory agencies in determining total maximum daily loads of nutrients for the basin in order to maintain dissolved oxygen greater than 90 percent of saturation and

Proceedings Abstracts: American Water Resources Association's Symposium on the National Water-Quality Assessment (NAWQA) Program--November 7-9, 1994, Chicago, Illinois
Approximately 418,000 pounds of triazine herbicides are applied annually to control weeds in crops grown in the Albemarle-Pamilico Sound drainage basin, located in North Carolina and Virginia. An enzyme-linked immunosorbent assay was used to detect concentrations of total triazine herbicides in streams draining into Albemarle-Pamlico Sound. Water samples were collected in May and June during the a
A summary of water-resources activities of the U.S. Geological Survey in Iowa, fiscal year 1994
Water-resources programs and activities of the U.S. Geological Survey in Iowa consist principally of hydrologic data collection and investigative studies that address water-resource issues. The work is supported by direct Federal funding, by transfer of funds from other Federal agencies, and by joint-funding agreements with State or local agencies.
