Borehole geophysics applied to ground-water investigations
W.S. Keys
1988, Open-File Report 87-539
The purpose of this manual is to provide hydrologists, geologists, and others who have the necessary training with the basic information needed to apply the most useful borehole-geophysical-logging techniques to the solution of problems in ground-water hydrology. Geophysical logs can provide information on the construction of wells and on the...
Ground-water resources and simulation of flow in aquifers containing freshwater and seawater, Island County, Washington
D. B. Sapik, Gilbert C. Bortleson, B. W. Drost, M. A. Jones, E. A. Prych
1988, Water-Resources Investigations Report 87-4182
Aquifers in Island County, Washington, that are intruded by seawater from Puget Sound contain chloride concentrations that exceed 100 mg/L. Chloride concentrations exceeded 100 mg/L in 24 % of the wells that were drilled below sea level and sampled in August 1981, but most of the chloride concentrations did not...
Simulation of flow in the Edwards Aquifer, San Antonio region, Texas, and refinement of storage and flow concepts
Robert W. Maclay, Larry F. Land
1988, Water Supply Paper 2336-A
The Edwards aquifer is a complexly faulted, carbonate aquifer lying within the Balcones fault zone of south-central Texas. The aquifer consists of thin- to massive-bedded limestone and dolomite, most of which is in the form of mudstones and wackestones. Well-developed secondary porosity has formed in association with former erosional surfaces...
A well system to recover usable water from a freshwater-saltwater aquifer in Puerto Rico
Allen L. Zack
1988, Water Supply Paper 2328
Aquifers in coastal areas of Puerto Rico commonly contain limited quantities of freshwater that occur as a thin layer at the surface of the water table. Many wells have been abandoned because well screens were inadvertently placed in saltwater parts of the aquifer. A scavenger/production well couple that can be...
Water-quality data for the Boise River, Boise to Star, Idaho, October to December 1987
S.A. Frenzel, T.F. Hansen
1988, Open-File Report 88-171
Chemical and physical data were collected at six and biological data at five sites on the Boise River between Veterans Memorial Parkway in Boise and Star, Idaho, from October to December 1987. Data were collected to determine the impact of sewage effluent from two Boise wastewater treatment plants on the...
Evaluation of the ground-water resources of the lower Susquehanna River basin, Pennsylvania and Maryland
James M. Gerhart, George J. Lazorchick
1988, Water Supply Paper 2284
Ground water in the 3,458-square-mile lower Susquehanna River basin occupies secondary openings in bedrock. The distribution of openings is a function of lithology, depth, and topography. Local flow systems account for most of the total ground-water flow. Average annual recharge for the lower basin is 1,857 million gallons per day,...
Seismicity map of the state of New Mexico
C. W. Stover, B.G. Reagor, S. T. Algermissen
1988, Miscellaneous Field Studies Map 2035
This map is one of a series of seismicity maps produced by the U. S. Geological Survey that show earthquake data of individual states or groups of states at the scale of 1:1,000,000. This map shows only those earthquakes with epicenters located within the boundaries of New Mexico, even though...
