Summary of the hydrology of the Floridan aquifer system in Florida and in parts of Georgia, South Carolina, and Alabama
The Floridan aquifer system is one of the major sources of ground-water supplies in the United States. This highly productive aquifer system underlies all of Florida, southern Georgia, and small parts of adjoining Alabama and South Carolina, for a total area of about 100,000 square miles. About 3 billion gallons of water per day is withdrawn from the aquifer for all uses, and, in many areas, the F

Ground-water hydraulics, regional flow, and ground-water development of the Floridan aquifer system in Florida and in parts of Georgia, South Carolina, and Alabama
The Floridan aquifer system is one of the major sources of groundwater supplies in the United States. This productive aquifer system underlies all of Florida, southeast Georgia, and small parts of adjoining Alabama and South Carolina, for a total area of about 100,000 square miles. About 3 billion gallons of water per day were withdrawn from the aquifer system in 1980, and in many areas the Florid

Water use on the Snake River plain, Idaho and eastern Oregon
Amounts of water withdrawn and consumptively used for irrigation
and other uses on the Snake River Plain were estimated to help deter-
mine hydrologic effects of ground- and surface-water use. Irrigation is
the largest off stream use of water on the plain. Surface-water irriga-
tion began in the 1840's and increased rapidly through the early 1900's.
Use of ground water for irrigation accelera

Solute geochemistry of the Snake River plain regional aquifer system, Idaho and eastern Oregon
Four geochemical approaches were used to determine chemical
reactions controlling solute concentrations in the Snake River Plain
regional aquifer system: (1) calculation of a solute balance within the
aquifer, (2) identification of weathered products in the aquifer frame-
work, (3) comparison of thermodynamic mineral saturation indices with
plausible solute reactions, and (4) comparison of st

A Modular Three-Dimensional Finite-Difference Ground-Water Flow Model
This report presents a finite-difference model and its associated modular computer program. The model simulates flow in three dimensions. The report includes detailed explanations of physical and mathematical concepts on which the model is based and an explanation of how those concepts are incorporated in the modular structure of the computer program. The modular structure consists of a Main Progr

Hydrodynamics of Denver basin: Explanation of subnormal fluid pressures
Anomalously low fluid potential (and hence subnormal fluid pressure) is found in Mesozoic and Paleozoic rocks of the Denver basin. The potentiometric surface for the Dakota and basal Cretaceous sandstones is 2,000-3,000 ft (600-900 m) beneath the land surface in parts of the Denver basin in Colorado and Nebraska. The potentiometric surface for pre-Pennsylvanian carbonate rocks is 1,500 ft (450 m)

Distribution of selenium in soils of agricultural fields, western San Joaquin Valley, California
Soils from three agricultural fields in the Panoche Creek alluvial fan area in the western San Joaquin Valley, California, were analyzed for soluble, adsorbed, and total concentrations of selenium (Se) to assess the distribution and forms of Se in relation to the leaching of Se from soils. This assessment is needed to evaluate the importance of soil Se in affecting ground water concentrations. Soi

A conceptual framework for assessing cumulative impacts on the hydrology of nontidal wetlands
Wetlands occur in geologic and hydrologic settings that enhance the accumulation or retention of water. Regional slope, local relief, and permeability of the land surface are major controls on the formation of wetlands by surface-water sources. However, these landscape features also have significant control over groundwater flow systems, which commonly play a role in the formation of wetlands. Bec

Geochemistry of groundwater in tertiary and cretaceous sediments of the southeastern Coastal Plain in eastern Georgia, South Carolina, and southeastern North Carolina
Geochemical samples of groundwater taken along hydrologic flow paths in eastern Georgia, South Carolina, and southeastern North Carolina, from noncalcareous sand aquifers, largely of Cretaceous age, are dominated by sodium and bicarbonate ions. Calcareous sand aquifers, largely of Tertiary age, contain water whose chemistry is dominated by calcium and bicarbonate ions, but may evolve downgradient

Distribution and mobility of selenium and other trace elements in shallow groundwater of the western San Joaquin Valley, California
Samples of shallow groundwater that underlies much of the irrigated area in the western San Joaquin Valley, CA, were analyzed for various major ions and trace elements, including selenium. Concentrations of the major ions generally were similar for groundwater collected in the two primary geologic zones - the alluvial fan and basin trough. Selenium concentrations are significantly (α = 0.05) highe
