Analysis of urban storm-water quality for seven basins near Portland, Oregon
Timothy L. Miller, Stuart W. McKenzie
1978, Open-File Report 78-662
Over a 1.5-year period, water-quality data were collected for seven small drainage basins in urban aeas of Portland, Oreg. Analysis of the data followed three approaches. First, the constituent concentrations were analyzed. Average concentrations of suspended sediment, settleable solids, and fecal coliform bacteria generally exceeded levels expected for secondary waste-treatment...
Method of estimating natural recharge to the Edwards Aquifer in the San Antonio area, Texas
Celso Puente
1978, Water-Resources Investigations Report 78-10
The method of estimating annual recharge is based on data collected from a network of stream-gaging stations and on assumptions related to applying the runoff characteristics from gaged areas to ungaged areas. The basic approach is a water-balance equation, in which recharge within a stream basin is the difference between...
Tin and related elements in sediments and beach sands from Afghanistan, Iran, and Turkey
J. A. Domenico, W.C. Overstreet, A.E. Hubert, R. B. Tripp
1978, Open-File Report 79-1188
Sixty samples of sediments from stream beds, outwash plains, and beaches were collected in Afghanistan, Iran, and Turkey by Fred L. Klinger,U.S. Bureau of Mines, as part of the field work undertaken by the National Geographic-Smithsonian Pyrotechnological Expedition of 1968. Facilities for the analysis of the samples for tin and...
Geohydrologic evaluation of a landfill in a coastal area, St Petersburg, Florida
C. B. Hutchinson, Joseph W. Stewart
1978, Water-Resources Investigations Report 77-78
The 250-acre Toytown landfill site is in a poorly-drained area in coastal Pinellas County, Florida. Average altitude of land surface at the landfill is less than 10 feet. About 1000 tons of solid waste and about 200,000 gallons of digested sewage sludge are disposed of daily at the landfill. The...
Surface water records of Cook Inlet basin, Alaska, through September 1975
David R. Scully, Larry S. Leveen, Raymond S. George
1978, Open-File Report 78-498
This report summarizes records of streamflow and water temperature collected prior to October 1, 1975, in the Cook Inlet Basin of south-central Alaska. Streamflow records for gaging stations are tabulated as monthly and annual summaries and annual extremes. For those gaging stations at which continuous or daily water temperature records...
Transport and dispersion of fluorescent tracer particles for the dune-bed condition, Atrisco Feeder Canal near Bernalillo, New Mexico
R. E. Rathbun, Vance C. Kennedy
1978, Professional Paper 1037
A fluorescent tracer technique was used to study the rates of transport and dispersion of sediment particles of various diameters and specific gravities for a dune-bed condition in an alluvial channel, Atrisco Feeder Canal near Bernalillo, N. Mex. The total transport rates of bed material measured by the steady-dilution and...
Limnology of Laguna Tortuguero, Puerto Rico
Ferdinand Quinones-Marquez, Luis A. Fuste
1978, Water-Resources Investigations Report 77-122
The principal chemical, physical and biological characteristics, and the hydrology of Laguna Tortuguero, Puerto Rico, were studied from 1974-75. The lagoon, with an area of 2.24 square kilometers and a volume of about 2.68 million cubic meters, contains about 5 percent of seawater. Drainage through a canal on the north...
Summary of the water resources of Puerto Rico
H.J. McCoy
1978, Open-File Report 78-971
The U.S. Department of Commerce (DOC) is the lead agency in the Federal Interagency Study of the Economy of Puerto Rico. At the request of DOC the U.S. Geological Survey is providing a discussion of the water resources of the island for inclusion in the study's section on macroeconomic assessment.Two...
A statistical summary and listing of the spectrographic analyses of heavy mineral concentrate and conventional, sieved stream-sediment samples, Silver City area, New Mexico
K. C. Watts, J.R. Hassemer, D. F. Siems, J. M. Nishi
1978, Open-File Report 78-801
Geochemical sampling of a tier of eight 7 1/2-minute quadrangles bordered by latitudes 32° 45'and 33° 00' N. and longitudes 108° 00' and 108° 30' W. was begun in the fall of 1974 and continued seasonally until completion in the fall of 1976. These quadrangles are in southwest New Mexico...
1978 Water Quality Laboratory services catalog
Linda C. Friedman
1978, Open-File Report 78-502
The information in this catalog is provided to assist field personnel in the selection of determinations, the estimation of costs, the calculation of sample volume requirements, the identification of the necessary sample treatment and in the evaluation of the precision of the laboratory data. The major section of the catalog...

Helen J. Davidson
1978, Open-File Report 78-98
The U.S. Geological Survey, in cooperation with the West Central Texas Municipal Water District and the Texas Department of Water Resources, is conducting a continuing program to determine the chemical quality of surface waters in the Hubbard Creek watershed. This report provides a compilation of the records for the period...
Summary appraisals of the nation's ground-water resources – Great Lakes region
William G. Weist Jr.
1978, Professional Paper 813-J
The Great Lakes Regions, as a whole, has abundant supplies of water. Nearly 805,000 billion cubic feet of water is contained in the Great Lakes. An additional 35,000 billion cubic feet of potable ground water is available from storage in the region. Estimated ground-water discharge to the streams and lakes...
Summary appraisals of the nation's ground-water resources – Hawaii region
K. J. Takasaki
1978, Professional Paper 813-M
The water resources of the Hawaii Region, taken as a whole, are far greater than foreseeable future demands on them, but this is not so for the individual islands. Each and every island is independent with respect to water supply, and the occurrence and availability of water vary widely from...
