1984, Water-Resources Investigations Report 84-4074
A state-wide water use survey was conducted of all public water suppliers and large, self-supplied industries in Tennessee. This report contains a summation of the data received from 463 public-water suppliers and 129 self-supplied water users. Analysis of the study results and findings indicate that many communities in Tennessee do...

A flow-routing model of the upper Schoharie Creek basin, New York, was developed and used to simulate high flows at the inlet of the Blenheim-Gilboa Reservoir. The flows from Schoharie Creek at Prattsville, the primary source of flow data in the basin, and tributary flows from the six minor basins...
Low-level radioactive-waste burial at the Palos Forest Preserve, Illinois: Geology and hydrology of the glacial drift, as related to the migration of tritium
Julio C. Olimpio
1984, Water Supply Paper 2226
A low-level radioactive-waste burial site is located in Palos Forest Preserve, about 22 kilometers southwest of Chicago, Illinois. Between 1943 and 1949 the site, named Plot M, was filled with radioactive waste from the first Argonne National Laboratory and from the University of Chicago Metallurgical Laboratory. Since 1973, tritium concentration...
Evaluation of the hydrologic system and potential effects of mining in the Dickinson lignite area, eastern slope and western Stark and Hettinger counties, North Dakota

1984, Water-Resources Investigations Report 84-4194
The investigation of the water resources of the Dickinson lignite area, an area of about 500 square miles, was undertaken to define the hydrologic system of the area and to project probable effects of coal mining on the system.Aquifers occur in sandstone beds in: the Fox Hills Sandstone and the...
International strategic minerals inventory summary report; chromium
J.H. DeYoung Jr., M. P. Lee, B. R. Lipin
1984, Circular 930-B
Major world resources of chromium, a strategic mineral commodity, are described in this summary report of information in the International Strategic Minerals Inventory {ISMI}. ISMI is a cooperative data-collection effort of earth-science and mineral-resource agencies in Australia, Canada, the Federal Republic of Germany, the Republic of South Africa, and the...
Nitrate in the Columbia Aquifer, central Delmarva Peninsula, Maryland
L. J. Bachman
1984, Water-Resources Investigations Report 84-4322
A study of nitrate in water from 604 wells tapping the Columbia aquifer on the Delmarva Peninsula in eastern Maryland describes the factors that affect nitrate variability. Samples were collected from 196 randomly selected wells and analyzed for nitrogen species. Many were also analyzed for major ions. In addition, results...
Ground-water monitoring at Santa Barbara, California: Phase 2 — Effects of pumping on water levels and on water quality in the Santa Barbara ground-water basin
Peter Martin
1984, Water Supply Paper 2197
From July 1978 to January 1980, water levels in the southern part of the Santa Barbara ground-water basin declined more than 100 feet. These water-level declines resulted from increases in municipal pumping since July 1978. The increase in municipal pumping was part of a basin-testing program designed to determine the...
Phenolic contamination in the sand-and-gravel aquifer from a surface impoundment of wood treatment wastes, Pensacola, Florida
D.E. Troutman, E.M. Godsy, D.F. Goerlitz, G. G. Ehrlich
1984, Water-Resources Investigations Report 84-4230
Creosote and pentachlorophenol wastewaters discharged to unlined surface impoundments have resulted in groundwater contamination in the vicinity of an industrial site near Pensacola, Florida. Total phenol concentrations of 36,000 microgm/liter have been detected 40 ft below land surface in a test hole 100 ft south of an overflow impoundment but...

Temporal dynamics and ecological significance of salinity stratification in an estuary (south San-Francisco Bay, USA)
James E. Cloern
1984, Oceanologica Acta (7) 137-141
South San Francisco Bay (USA) has periodic variations in salinity stratification that coïncide with neap-spring tidal variations during the winter "wet" season, but it remains well-mixed during summer and fall. The degree of salinity stratification, and timing of stratification events, can be predicted from a simple empirical function of river...
Gas exchange rates across the sediment-water and air-water interfaces in south San Francisco Bay

Finite element solution methods for circulation in estuaries
Roy A. Walters
J. P. Laible, C.A. Brebbia, W. Gray, G. Pinder, editor(s)
1984, Book chapter, Finite elements in water resources
In this paper, the shallow water equations are used to approximate the depth-mean circulation in estuaries.  The time scales of the motions can be conveniently divided into three ranges: 1) low-frequency (residual) variations with periods of two days or longer, 2) tidal-frequency variations, and 3) high-frequency variations with periods of...
Response of northern San Francisco Bay to riverine inputs of dissolved inorganic carbon, silicon, nitrogen and phosphorus
Laurence E. Schemel, Dana D. Harmon, Stephen W. Eager, David H. Peterson
Victor S. Kennedy, editor(s)
1984, Book chapter, The estuary as a filter
Estuarine processes can be effective in modifying (filtering) distributions of dissolved inorganic forms of carbon (DIC), silicon (DIS), nitrogen (DIN), and phosphorus (DIP) in northern San Francisco Bay. During winter, high inflow from the Sacramento-San Joaquin river system supplied these nutrients to the estuary at rates that exceeded potential rates...
