Inflatable straddle packers and associated equipment for hydraulic fracturing and hydrologic testing
Eugene Shuter, Robert R. Pemberton
1978, Water-Resources Investigations Report 78-55
Independent aquifer testing is the only way to fully understand the hydrology encountered in boreholes intersecting multiple aquifers. The most feasible method to accomplish the testing of multiple aquifer wells is through the use inflatable packers. The straddle packers and associated equipment herein described arE valuable tools for making isolated...
Water resources of northeast North Carolina
Hugh B. Wilder, Tully M. Robison, K.L. Lindskov
1978, Water-Resources Investigations Report 77-81
Several water-related problems are associated with economic development of northeast North Carolina. The solution to these problems depends in part on adequate knowledge of the hydrology of this 8,930 square mile coastal area. Average annual precipitation on the area is about 50 inches. Of this amount, about 34 inches returns...
Bacteriological water quality of Tulpehocken Creek basin, Berks and Lebanon Counties, Pennsylvania
James L. Barker
1978, Water-Resources Investigations Report 78-53
A four month intensive study of the bacteriological quality of water in the Tulpehocken Creek basin indicates that (1) the streams locally contain high densities of bacteria indicative of fecal contamination, (2) nonpoint waste sources, particularly livestock, are the dominant influence in the excessive bacteriological-indicator counts observed, and (3) retention...
Water-quality data from a sludge disposal test site, St. Petersburg, Florida, November 1973-July 1977
Mario Fernandez
1978, Open-File Report 78-821
From November 1973 to July 1977, water samples were collected from wells to identify background water-quality conditions and to determine the effects on ground-water quality by St. Petersburg 's sludge-disposal operation (sod farm). Specific conductance and pH were determined in the field. Samples were collected for laboratory determination of selected...
Technique for estimating the magnitude and frequency of floods in St. Louis County, Missouri
Donald Webster Spencer, Terry W. Alexander
1978, Water-Resources Investigations Report 78-139
Equations and nomographs in.this report can be used to estimate peak flood-discharges having recurrence intervals up to 100 years in rural and urban areas of St. Louis County, Mo. The basin characteristics significant at the 5-percent probability level were drainage area and percentage imperviousness. Drainage area can be measured from...
FRISK: computer program for seismic risk analysis using faults as earthquake sources
Robin K. McGuire
1978, Open-File Report 78-1007
This computer program makes probabilistic seismic hazard calculations at sites affected by earthquakes occurring on faults which are defined by the user as a series of line segments. The length of rupture of the fault as a function of earthquake magnitude is accounted for, and ground motion estimates at the...
The Mississippi River Valley alluvial aquifer in Mississippi
G.J. Dalsin
1978, Water-Resources Investigations Report 78-106
The Mississippi River valley alluvial aquifer, of Quaternary age , contains freshwater in an area of 7,000 sq mi adjacent to the Mississippi River in northwestern Mississippi, and in a 500 sq mi irregular area in southwestern Mississippi. It is the highest yielding aquifer in Mississippi with individual well yields...
Hot, deep origin of petroleum: deep basin evidence and application
Leigh C. Price
1978, Open-File Report 78-1020
Use of the model of a hot deep origin of oil places rigid constraints on the migration and entrapment of crude oil. Specifically, oil originating from depth migrates vertically up faults and is emplaced in traps at shallower depths. Review of petroleum-producing basins worldwide shows oil occurrence in these basins...
Description of CRIB, the GIPSY retrieval mechanism, and the interface to the General Electric MARK III Service : CRIB, the mineral resources data bank of the U.S. Geological Survey--guide for public users, 1977
James Alfred Calkins, Eleanor K. Keefer, Regina A. Ofsharick, George T. Mason, Patricia Tracy, Mary Atkins
1978, Circular 755-A
The U.S. Geological Survey's Computerized Resources Information Bank (CRIB) is being made available for public use through the computer facilities of the University of Oklahoma and the General Electric Company, U.S.A. The use of General Electric's worldwide information-services network provides access to the CRIB file to a worldwide clientele. This...
Ground-water conditions in the Eureka area, Humboldt County, California, 1975
Michael J. Johnson
1978, Water-Resources Investigations Report 78-127
Ground-water conditions in the Eureka area, Calif., were evaluated during 1975 to determine whether significant changes had occurred since 1952, when an earlier reconnaissance was made. No major changes in water levels or water quality were noted at 1975 pumping rates. Recharge to the ground-water system compensates for both artificial...
