Fluctuations of ground-water levels in Lee County, Florida, in 1975 water year
T.H. O’Donnell
1977, Open-File Report 76-854
During the 1975 water year, rainfall was about average at Page Field, Florida, and from 20-25 percent below average at Lehigh Acres and Sanibel Island. Water levels were monitored in 57 observation wells in Lee County, Florida. Of the 23 wells that tap the water-table aquifer, one record high and...
Preliminary study of sources and processes of enrichment of manganese in water from University of Rhode Island supply wells
William Dudley Silvey, Herbert E. Johnston
1977, Open-File Report 77-561
Concentrations of dissolved manganese have increased from 0.0 to as much as 3.3 mg/liter over a period of years in closely spaced University of Rhode Island supply wells. The wells tap stratified glacial deposits and derive part of their water from infiltration from a nearby river-pond system. The principal sources...
Water table in the surficial aquifer and potentiometric surface of the Floridan Aquifer in selected well fields, west-central Florida, September 1976
Paul D. Ryder, L. R. Mills
1977, Open-File Report 77-551
The water table in the surficial aquifer and the potentiometric surface of the Florida aquifer in a 1200 square-mile area in west-central Florida are mapped semiannually by the U. S. Geological Survey. Maps are prepared on the basis of water levels measured in wells each May to coincide with seasonal...
Water resources of the Chehalis Indian Reservation, Washington
H. E. Pearson, G.T. Higgins
1977, Open-File Report 77-704
Ground water beneath the 6.6-square-mile Chehalis Indian Reservation, Wash., most of which lies on a flood plain, occurs in the alluvial and terrace sand and gravel deposits. Supplies available within the depth zone of water-level fluctuations are estimated to be between 20 and 60 times that being pumped at the...
Water-level records for the lower Arkansas River Valley of Colorado, 1973-77
Robert D. Penley
1977, Open-File Report 77-560
Water-level measurements made in more than 465 wells in March 1977 in the lower Arkansas River valley of southeastern Colorado are presented. Measurements for the preceding 4 years are included to serve as references illustrating declining or rising water levels. Changes in water levels from December 1975 to March 1977...
Water-level records for the San Luis Valley of Colorado, 1973-77
Robert D. Penley
1977, Open-File Report 77-265
Water-level measurements were made in 122 wells in January 1977. Changes in water levels from January 1976 to January 1977 ranged from a rise of 10.0 feet (3.0 meters) to a decline of 8.6 feet (2.6 meters) both of which occurred in Costilla County. Measurements for the three preceding winters...
The Pierre Shale, northern Great Plains; a potential isolation medium for radioactive waste
George W. Shurr
1977, Open-File Report 77-776
The purpose of this reconnaissance is to assess the potential of the Pierre Shale, of Late Cretaceous age, as a possible isolation medium for radioactive wastes. The regional stratigraphic and structural setting of the Pierre Shale in the northern Great Plains is summarized from subsurface data. Geologic attributes mapped and...
Atlantic Margin Coring Project 1976: Preliminary Report on Shipboard and Some Laboratory Geotechnical data
Adrian F. Richards
1977, Open-File Report 78-123
This report presents reduced shipboard geotechnical data collected during the 1976 Atlantic Margin Coring Project; results of laboratory tests of specific gravity, water content, bulk density, and Atterberg limits; and sedimentation-compression e log p curves showing consolidation. A description of the procedures used at sea and in the laboratory and...
Geology and ground water in Door County, Wisconsin, with emphasis on contamination potential in the Silurian dolomite
Marvin G. Sherrill
1977, Open-File Report 77-61
Door County, a recreational and fruit-growing area bordering Lake Michigan in northeastern Wisconsin, has had a long history of ground-water contamination from surface and near-surface sources. Contamination is most severe in late summer when fruit-canning operations and the influx of tourists create additional wastes. Silurian dolomite is the upper bedrock...
Preliminary data on some Precambrian deposits of zinc-copper-lead sulfides and zinc spinel (granite) in Colorado
Douglas M. Sheridan, William H. Raymond
1977, Open-File Report 77-607
Precambrian sulfide deposits in the Southern Rocky Mountains in Colorado are being studied and re-evaluated according to geologic concepts which were developed in recent years in other parts of the world during successful research regarding economic massive sulfide deposits. These studies, initiated in 1974 in Colorado by the U.S. Geological...
Reconnaissance engineering geology of the Metlakatla area, Annette Island, Alaska, with emphasis on evaluation of earthquakes and other geologic hazards
Lynn A. Yehle
1977, Open-File Report 77-272
A program to study the engineering geology of most larger Alaska coastal communities and to evaluate their earthquake and other geologic hazards was started following the 1964 Alaska earthquake; this report about the Metlakatla area, Annette Island, is a product of that program. Field-study methods were of a reconnaissance nature,...
