Impact of development on availability and quality of ground water in eastern Nassau County, Florida, and southeastern Camden County, Georgia
D.P. Brown
1984, Water-Resources Investigations Report 83-4190
The primary sources of water in the area are from the surficial and Floridan aquifers. The surficial aquifer, consisting of thin permeable zones of sand, shell, and limestone, provides limited water supplies (10-50 gallons per minute). Its estimated transmissivity ranges from less than 100 to 10,000 feet squared per day....
Maps showing distribution of dissolved solids and dominant chemical type in ground water, Basin and Range Province, Oregon
Thomas H. Thompson, Richard Chappell, J. B. Gonthier, W. D. McFarland
1984, Water-Resources Investigations Report 83-4120-C
This map report is one of a series of geologic and hydrologic maps of States in the Basin and Range Province. These map reports contain information on ground-water hydrology, ground-water quality, surface distribution of selected rock types, data on tectonic conditions, areal geophysical data, Pleistocene lakes and marshes and natural...
Analysis of the Carmel Valley alluvial ground-water basin, Monterey County, California
Glenn W. Kapple, Hugh T. Mitten, Timothy J. Durbin, Michael J. Johnson
1984, Water-Resources Investigations Report 83-4280
A two-dimensional, finite-element, digital model was developed for the Carmel Valley alluvial ground-water basin using measured, computed, and estimated discharge and recharge data for the basin. Discharge data included evapotranspiration by phreatophytes and agricultural, municipal, and domestic pumpage. Recharge data included river leakage, tributary runoff, and pumping return flow. Recharge...
Aquifer tests at the Jackpile-Paguate uranium mine, Pueblo of Laguna, west-central New Mexico
D. W. Risser, P. A. Davis, J. A. Baldwin, D. P. McaAda
1984, Water-Resources Investigations Report 84-4255
The transmissivity of the Jackpile sandstone bed in the Brushy Basin Shale Member of the Morrison Formation, west-central New Mexico, was determined to be 24 sq ft/day at well M2 and 47 sq ft/day at well M3 from constant-discharge aquifer tests conducted at the Jackpile-Paguate Uranium Mine. The storage coefficient...
Evaluation of future base-flow water-quality conditions in the Hillsborough River, Florida
Mario Fernandez Jr., C. L. Goetz, J.E. Miller
1984, Water-Resources Investigations Report 83-4182
A one-dimensional, steady-state, water-quality model was developed for a 30.0 mile reach of the Hillsborough River to evaluate water-quality conditions to be expected from future development. The model was calibrated and verified using data collected under critical base-flow conditions in April and December 1978. Dissolved organic nitrogen, nitrate nitrogen, and...
Chemical quality of landfill leachate in treatment ponds and migration of leachate in the surficial aquifer, Pinellas County, Florida
Mario Fernandez Jr., G. L. Barr
1984, Water-Resources Investigations Report 83-4193
The Pinellas County leachate treatment and disposal site encompasses about 8 acres within the 220 acres of the county 's Bridgeway Acres landfill. The site has a high water table and is subject to inundation due to tidal flooding and major storms. Fresh leachate is pumped from V-shaped trenches an...
Ground water in the Dickson area of the western Highland Rim of Tennessee
M. W. Bradley
1984, Water-Resources Investigations Report 82-4088
A hydrologic study of the Dickson, Tennessee, area provided additional information on the occurrence of ground water in the Mississippian carbonate rocks of the western Highland Rim. Twenty-six test wells were drilled to determine the occurrence of ground water in relation to topographic position, regolith thickness, streamflow gains or losses,...
Seismicity map of the state of Colorado
C. W. Stover, B.G. Reagor, S. T. Algermissen
1984, Miscellaneous Field Studies Map 1694
The data shown on this map and listed in table 1 are for earthquakes that were originally included in a study of seismic risk in the United States (Algermissen, 1969). This data file has been recompiled and updated through 1981. Some revisions of epicenters and intensities in the original file...
Quantity and quality of streamflow in the White River basin, Colorado and Utah
J. M. Boyle, K.J. Covay, D. P. Bauer
1984, Water-Resources Investigations Report 84-4022
The water quality and flow of existing streams in the White River basin, located in northwestern Colorado and northeastern Utah, are adequate for present uses, but future development (such as energy) may affect stream quality and quantity. Present conditions are described as a baseline to enable planners to allocate available...
Magnitude and frequency of flood volumes for urban watersheds in Leon County, Florida
M.A. Franklin
1984, Water-Resources Investigations Report 84-4233
Techniques are provided for estimating runoff magnitudes for urban-flow streams in Leon County, Florida, for recurrence intervals of 2, 5, 10, 25, 50, 100, and 500 years. Synthetic runoff volumes were generated by using a calibrated lumped-parameter rainfall-runoff model, pan evaporation data from Milton, Florida, and long-term unit rainfall records...
Nitrogen, sulfate, chloride, and manganese in ground water in the alluvial deposits of the South Platte River Valley near Greeley, Weld County, Colorado
N. G. Gaggiani
1984, Water-Resources Investigations Report 84-4088
Ground water from the valley-fill deposits of the South Platte River Valley and its tributaries is used extensively for agriculture in the study area, about 10 miles east of Greeley and about 50 miles northeast of Denver, Colorado. The valley-fill deposits, which consist of alluvial and terrace deposits, are in...
Preliminary study of the aquifers of the lower Mesilla Valley in Texas and New Mexico by model simulation
J. S. Gates, D. E. White, E. R. Leggat
1984, Water-Resources Investigations Report 84-4317
The aquifers in the lower Mesilla Valley of Texas and New Mexico provide water for irrigation, industrial use, and municipal supply. At present (1984), the shallow aquifer is used principally for irrigation. The medium-depth aquifer (the top of which is about 160 to 260 feet below land surface) and deep...
