Source, use, and disposition of water in Florida, 1975
Stanley D. Leach
1978, Water-Resources Investigations Report 78-17
On the average, 18,420 million gallons of water was withdrawn for use in Florida each day in 1975--an increase of 3,107 million gallons per day (Mgal/d) rate since 1970. The 1975 daily total was made up of 11,502 million gallons of saline water and 6,918 million gallons of freshwater. The...
Altitude and configuration of the top of the Floridan Aquifer, Duval County, Florida
G.W. Leve
1978, Water-Resources Investigations Report 77-114
Structural contours on the top of the Floridan aquifer in Duval County, Florida, show that the top of the aquifer ranges from less than 300 feet below sea level to more than 600 feet below sea level. Two inferred concealed faults occur in the aquifer; one trending northeast-southwest in the...
Flow characteristics of streams in Tutuila, American Samoa
Iwao Matsuoka
1978, Water-Resources Investigations Report 78-103
The island of Tutuila is the economic and population center of American Samoa. It lies in the tropics and rainfall is abundant. Annual rainfall at upper Faga'alu reservoir averaged 207 inches during the period 1904-75. Available records show that altitude is a significant factor affecting the amount of rainfall. Small,...
Summary of water resources for the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and vicinity, San Diego County, California
W. R. Moyle, D.J. Downing
1978, Open-File Report 77-684
Since 1945, precipitation and runoff in California on the Campo, Cuyapaipe, La Posta, and Manzanita Indian Reservations and surrounding areas generally have been below normal, and ground-water levels are declining. Most of the water is of excellent quality. The analysis of water from one well on the Campo Reservation indicates...
Map showing ground-water conditions in the House Rock area, Coconino County, Arizona-- 1976
G. W. Levings, C. D. Farrar
1978, Water-Resources Investigations Report 78-15
The House Rock area includes about 1,500 sq mi in north-central Arizona. Ground water is present in several aquifers that are made up of one or more formations. In the Paria Plateau and Wahweap areas ground water is obtained from the N aquifer, which includes the Navajo Sandstone, Kayenta Formation,...
Geohydrology of the northern Louisiana salt-dome basin pertinent to the storage of radioactive wastes; a progress report
R. L. Hosman
1978, Water-Resources Investigations Report 78-104
Salt domes in northern Louisiana are being considered as possible storage sites for nuclear wastes. The domes are in an area that received regional sedimentation through early Tertiary (Eocene) time with lesser amounts of Quaternary deposits. The Cretaceous-Tertiary accumulation is a few thousand feet thick; the major sands are regional...
Appraisal of uncontrolled flowing artesian wells in Florida
Henry G. Healy
1978, Water-Resources Investigations Report 78-95
An estimated 15,000 uncontrolled flowing wells, many discharging water of poor quality are wastefully discharging about 790 million gallons per day by surface and internal flow. Internal flow in principal problem areas have been identified in Brevard, Charlotte, Clay, De Soto, Duval, Flagler, Glades, Hendry, Hillsborough, Lee, Manatee, Martin, Nassau,...
Flood profiles for lower Brooker Creek, west-central Florida
W.R. Murphy
1978, Water-Resources Investigations Report 77-115
Flood heights are computed for a range of recurrence intervals for a 12.6 mile reach of Brooker Creek, beginning at the mouth at Lake Tarpon. A Geological Survey step-backwater computer program, E431, was used in these analyses using: (1) Stream and valley cross-section geometry and roughness data; (2) Recurrence interval...
Nitrogen, phosphorus, organic carbon, and biochemical oxygen demand: in Florida surface waters, 1972
Matthew I. Kaufman, J.E. Dysart
1978, Water-Resources Investigations Report 78-43
Water samples were collected during spring and autumn 1972 from about 100 surface-water sites in Florida. The samples were analyzed for the plant nutrients, nitrogen and phosphorus. In most waters, nitrogen concentrations are less than 2.0 milligrams per liter as nitrogen, and organic nitrogen is dominant. Median total nitrogen concentration...
A rainfall-runoff modeling procedure for improving estimates of T-year (annual) floods for small drainage basins
Robert W. Lichty, Fred Liscum
1978, Water-Resources Investigations Report 78-7
Maps depicting the influence of a climatic factor, C, on the magnitude of synthetic T-year (annual) floods were prepared for a large portion of the eastern United States. The climatic factors were developed by regression analysis of flood data using a parametric rainfall-runoff model and long-term rainfall records. Map estimates...
Digital-model simulation of the glacial-outwash aquifer, Otter Creek-Dry Creek basin, Cortland County, New York
O. J. Cosner, J. F. Harsh
1978, Water-Resources Investigations Report 78-71
The city of Cortland, New York, and surrounding areas obtain water from the highly productive glacial-outwash aquifer underlying the Otter Creek-Dry Creek basin. Pumpage from the aquifer in 1976 was approximately 6.3 million gallons per day and is expected to increase as a result of population growth and urbanization. A...
Computer modeling of ground-water availability in the Pootatuck River Valley, Newtown, Connecticut
F.P. Haeni, Elinor H. Handman
1978, Water-Resources Investigations Report 78-77
A hydrologic analysis of the stratified drift in Newtown, Conn., based on available data, test drilling, seismic refraction profiling, and the stream-aquifer connection was performed using a digital computer model. Simulated pumping indicates that a total of 4.0 million gallons of water per day (Mgal/d) can be withdrawn from the...
Evaluation of the geologic and hydrologic factors related to the waste-storage potential of Mesozoic aquifers in the southern part of the Atlantic Coastal Plain, South Carolina and Georgia
Philip M. Brown, D.L. Brown, M.S. Reid, O. B. Lloyd Jr.
1978, Open-File Report 78-292
This report describes the subsurface distribution of rocks of Cretaceous to Late Jurassic(?) age in the Atlantic. Coastal Plain, South Carolina and Georgia, and examines their potential for deep-well waste storage. For mapping purposes a waste-storage "operational unit" is established and defined. It is a sand or sandstone layer, 20...
