Oregon ground-water quality and its relation to hydrogeologic factors — A statistical approach
T. L. Miller, J. B. Gonthier
1984, Water-Resources Investigations Report 84-4242
An appraisal of Oregon ground-water quality was made using existing data accessible through the U.S. Geological Survey computer system. The data available for about 1,000 sites were separated by aquifer units and hydrologic units. Selected statistical moments were described for 19 constituents including major ions. About 96 percent of all...

1984, Water-Resources Investigations Report 83-4271
Brown ditch drains wetlands between three parallel ridges of sand dunes near the East Unit of Indiana Dunes National Lakeshore in Poter County, Indiana. Dune and lacustrine sands form a surficial aquifer that is the source of base flow to the ditch. Profiles established in July and August 1982 show...
Estimate of self-supplied domestic water use in Oklahoma during 1980
J.D. Stoner
1984, Water-Resources Investigations Report 83-4223
Reported or measured water-use data for the domestic self-supplied user were not available for Oklahoma; therefore estimates of water use within this classification were derived. The total self-supplied population in Oklahoma during 1980 was estimated to be 343,615, which was 11.4 percent of the total 1980 State population. The rate...

Water-quality appraisal, Mammoth Creek and Hot Creek, Mono County, California
J. G. Setmire
1984, Water-Resources Investigations Report 84-4060
A late summer reconnaissance in 1981 and a spring high-flow sampling in 1982 of Mammoth Creek and Hot Creek, located in the Mammoth crest area of the Sierra Nevada, indicated that mineralization, eutrophication, sedimentation, and limited areas of fecal contamination were occurring. Mineralization, indicated by a downstream increase in dissolved-solids...

1984, Water-Resources Investigations Report 84-4188
The U.S. Geological Survey has begun a research project to improve understanding of the mobilization, transport, and fate of petroleum contaminants in the shallow subsurface and to use this understanding to develop predictive models of contaminant behavior. The project site is near Bemidji in northern Minnesota where an accidental spill of...
Hydrologic conditions in the Chicod Creek basin, North Carolina, before and during channel modifications, 1975-81
S.A. Watkins, C.E. Simmons
1984, Water-Resources Investigations Report 84-4025
Beginning in late 1978, stream channels throughout the 60-square mile Chicod Creek basin underwent extensive modification to increase drainage efficiency and reduce flooding potential. Drainage modifications in this Coastal Plain basin, consisting primarily of channel excavation and clearing of channel blockages, were completed in December 1981. The hydrologic condition of...
Ground water in the Fresno area, California; preliminary report
H. T. Mitten
1984, Water-Resources Investigations Report 83-4246
The U.S. Geological Survey, in cooperation with Fresno County, is developing a computer model of the unconfined aquifer system in the Fresno area. In the area, consolidated rocks are overlain by unconsolidated deposits. The unconsolidated deposits are divided into a lower fine-grained unit and an overlying coarse-grained unit. The system...

The Palau Islands are a group of 350 islands, ranging in size from a few hundred square feet to the 153-square-mile island of Babelthuap. Babelthuap is the second largest island in the Western Pacific and comprises more than 80 percent of the total land area of the Palau Islands. Most...
Reconnaissance of the shallow-unconfined aquifer in Salt Lake Valley, Utah
R. L. Seiler, K.M. Waddell
1984, Water-Resources Investigations Report 83-4272
The shallow-unconfined aquifer in Salt Lake (Jordan) Valley, Utah, seldom is used for domestic or industrial purposes because it yields water slowly and is readily contaminated. The water in the aquifer, however, can flood basements and is a potential source of contamination to other water supplies. In about one-half of...

D. P. McAda
1984, Water-Resources Investigations Report 84-4062
A two-dimensional digital ground-water flow model was constructed of the Ogallala aquifer in Lea County, New Mexico. Simulations of predevelopment steady-state and historical pumping conditions were used to fit the model. Projections of water-level declines were made based on the condition of no additional development and the condition of a...
