The determination of total volatiles in rocks by loss-on-fusion
V.G. Mossotti, B. King
1982, Open-File Report 82-587
A fast and accurate technique has been developed for the determination of the total volatile content of rocks. The loss on fusion (LOF) results are comparable to the conventional time-consuming wet-chemical procedure but require no additional effort or cost when conducted as part of the usual sample preparation procedure for...

A computer program for calculating relative-transmissivity input arrays to aid model calibration
Emanuel Weiss
1982, Open-File Report 82-447
A program is documented that calculates a transmissivity distribution for input to a digital ground-water flow model. Factors that are taken into account in the calculation are: aquifer thickness, ground-water viscosity and its dependence on temperature and dissolved solids, and permeability and its dependence on overburden pressure. Other factors affecting...
Analyzing thematic maps and mapping for accuracy
G.H. Rosenfield
1982, Open-File Report 82-239
Two problems which exist while attempting to test the accuracy of thematic maps and mapping are: (1) evaluating the accuracy of thematic content, and (2) evaluating the effects of the variables on thematic mapping. Statistical analysis techniques are applicable to both these problems and include techniques for sampling the data...
Baseline water-quality data for sand-plain aquifers in Hubbard, Morrison, Otter Tail, and Wadena counties, Minnesota
C. F. Myette
1982, Open-File Report 82-909
Tapping the surficial sand-plain aquifers in west-central Minnesota has raised the possibility for degradation of water quality. The sand-plain areas are generally overlain by sandy soils that permit rapid infiltration of precipitation and, possibly, of surface contaminants. One hundred twenty-five wells were sampled in Hubbard, Morrison, Otter Tail, and Wadena...

Water-quality assessment of the American River, California
M.V. Shulters
1982, Open-File Report 82-763
Based on an analysis of water-quality data from more than 168 sites, the American River was found to be of overall good quality and suitable for all beneficial uses specified by the State of California, even though its natural condition has been altered by man 's activities in the basin....
Storage and retrieval of ground-water data at the U.S. Geological Survey
Maria W. Mercer, Charles O. Morgan
1982, Circular 856
The U.S. Geological Survey maintains a computerized Ground-Water Site-Inventory (GWSI) file that contains information about wells and springs at sites from all States of the United States. This file contains data collected by U.S. Geological Survey personnel and personnel of cooperating State, local and Federal agencies. The file is easily...

Potential impacts of a proposed reservoir on hydrologic and water-quality conditions in Little Rush Creek watershed, Fairfield County, Ohio
Janet Hren, R.L. Jones
1982, Open-File Report 82-109
Water-quality and discharge measurements were made at three sites on Indian Run and one site on Little Rush Creek between February and December, 1979. Indian Run was observed above and below the U.S. Soil Conservation Service Reservoir, VI-D. Little Rush Creek was observed 1.1 miles downstream from the proposed U.S....
An index of geophysical well logging in Virginia by the U.S. Geological Survey
M. Patrick Mulheren, J. D. Larson, Herbert T. Hopkins
1982, Open-File Report 82-432
Geophysical logs have been obtained in more than 170 wells in Virginia by the U.S. Geological Survey since 1968. These logs include natural gamma, electric, caliper, temperature, fluid conductivity, and fluid velocity. Most of the logs are for wells in the Coastal Plain Province of eastern Virginia. Geophysical logs aid...
