Quality-of-water data, Palm Beach County, Florida, 1970-1975
Wesley L. Miller, Arthur C. Lietz
1976, Open-File Report 76-784
One of the most pressing problems of Palm Beach County, Florida, is the present and potential contamination of the surface and ground-water resources. The canals which dissect the urban and agricultural areas are convenient receptacles for storm-water runoff, sewage effluent, and agricultural wastes. Contaminants in the canals may enter the...
Ground-water levels in observation wells in Oklahoma, 1971-74
Robert L. Goemaat
1976, Open-File Report 76-664
The objectives of the observation-well program are (1) to provide long-term records of water-level fluctuations in representative wells, (2) to facilitate the prediction of water-level trends and indicate the future availability of ground-water supplies, and (3) to provide information for use in basic research. These selected records serve as a...
Sediment characteristics of streams in the eastern Piedmont and western Coastal Plain regions of North Carolina
Clyde E. Simmons
1976, Water Supply Paper 1798-O
The sediment-transport characteristics of streams were determined in a 15,500-square-kilometre (6,000-square-mile) area of the Coastal Plain and Piedmont regions of eastern North Carolina during 1969-73. The study covered all or parts of 21 counties and included data for 28 sediment-sampling stations in parts of 4 major river basins?the Roanoke, Pamlico,...
Progress report on geology of the Edwards aquifer, San Antonio area, Texas, and preliminary interpretation of borehole geophysical and laboratory data on carbonate rocks
Robert W. Maclay, Ted A. Small
1976, Open-File Report 76-627
This report describes the geology and porosity of the rocks of the Edwards aquifer, with particular attention to the eastern half of the San Antonio area. The data were obtained from geologic and geophysical studies of nine cored test holes, from laboratory analyses of samples of the aquifer materials, and...
Spectrographic and chemical analyses of geochemical samples from the McCarthy Quadrangle, Alaska
Richard M. O’Leary, Steven K. McDanal, Gordon W. Day, Christine McDougal, Keith Robinson
1976, Open-File Report 76-824
As an integral part of the Alaskan Mineral Resource Assessment Program, a geochemical reconnaissance survey was conducted in the McCarthy quadrangle during the summer of 1974. The investigation consisted of geochemical sampling, multielement chemical and spectrographic analyses, compilation of new and existing geochemical data, statistical evaluation of the total data...
Finite difference model for aquifer simulation in two dimensions with results of numerical experiments
Peter C. Trescott, George Francis Pinder, S. P. Larson
1976, Techniques of Water-Resources Investigations 07-C1
The model will simulate ground-water flow in an artesian aquifer, a water-table aquifer, or a combined artesian and water-table aquifer. The aquifer may be heterogeneous and anisotropic and have irregular boundaries. The source term in the flow equation may include well discharge, constant recharge, leakage from confining beds in which...
Monitoring irrigated land acreage using Landsat imagery: an application example
William C. Draeger
1976, Open-File Report 76-630
A demonstration of the utility of Landsat imagery for quickly and cheaply estimating irrigated land area was conducted in the Klamath River basin of Oregon. Landsat color composite images, at 1:250,000 scale and acquired on two dates during the 1975 growing season, were interpreted. Irrigated lands were delineated manually, and...
Hydrology and sedimentation of Bixler Run Basin, central Pennsylvania
Lloyd A. Reed
1976, Water Supply Paper 1798-N
Rainfall, streamflow, stream chemical, and sediment discharge data were collected from Bixler Run near Loysville, Pa., during the period from February 1954 to September 1969 as part of a project to evaluate sediment discharge from an agricultural area in which soil-conservation techniques were being adopted at a moderate rate. The...
Interpretation and description of seismic data from Lower Cook Inlet, Alaska
Michael A. Fisher
1976, Open-File Report 76-561
A coarse grid of 480 kilometres of seismic lines was collected in lower Cook Inlet, Alaska between Homer on the north and Cape Douglas on the south. Paper and mylar copies of the seismic sections and shot point maps are available to the public from NOAA in Boulder, Colorado.The seismic...
Geologic appraisal of the petroleum potential of offshore southern California; the borderland compared to onshore coastal basins
James Carlton Taylor
1976, Circular 730
Offshore southern California is part of a much larger Pacific continental margin, and the two areas have a similar geologic history at least as far back as middle Tertiary time. Assessment of the petroleum potential of the offshore Southern California borderland is accomplished by examining the adjacent highly explored productive...
Geological and geochemical reconnaissance in the central Santander Massif, Departments of Santander and Norte de Santander, Colombia
James George Evans
1976, Open-File Report 77-281
The central Santander Massif is composed of Precambrian Bucaramanga Gneiss and pre-Devonian Silgara Formation intruded by Mesozoic quartz diorite, quartz monzonite, and alaskite and Cretaceous or younger porphyry. Triassic (Bocas Formation), Jurassic (Jordan and Giron Formations).and Cretaceous (Tambor, Rosa Blanca, Paja, Tablazo, Simiti, La Luna, and Umir Formations) sedimentary rocks...
Selected hydrologic data, Clarion River and Redbank Creek basins, northwestern Pennsylvania: an interim report
Harry E. Koester, Joseph B. Lescinsky
1976, Open-File Report 76-445
This report presents basic hydrologic data collected for part of a water-resources study and supplements an interpretive report which will be published separately. The report summarizes discharge data from 140 stream collection sites, contains tables of about 800 chemical analyses from 164 stream sites and 107 analyses from 91 abandoned...
Hydrologic analysis and river-quality data programs
Walter G. Hines, David A. Rickert, Stuart W. McKenzie
1976, Circular 715-D
For nearly half a century the Willamette River in Oregon experienced severe dissolved-oxygen problems related to large loads of organically rich waste waters from industries and municipalities. Since the mid-1950 's dissolved oxygen quality has gradually improved owing to low-flow augmentation, the achievement of basinwide secondary treatment, and the use...

Edgar A. Imhoff, Thomas O. Friz, James R. LaFevers
1976, Circular 731
During 1975 inquiries of agencies in each State and review of State statutes and related administrative codes revealed that 38 States have established programs requiring the reclamation of surface mined lands. Results of analyses of those programs and ancillary data are presented in : (1) A table (matrix) which has...
