1984, Edwards Underground Water District Bulletin 41
The average annual ground-water recharge to the Edwards aquifer in the San Antonio area, Texas, from 1934 through 1981, was 612,400 acre-feet. The recharge in 1981 was 1,448,400 acre-feet, which is the third highest annual recharge since 1934. A maximum annual recharge of 1,711,200 acre-feet occurred in 1958, and a...

Volatilization of chlorinated hydrocarbons from water
R. E. Rathbun, D. Y. Tai
1984, Book chapter, Gas transfer at water surfaces
Coefficients for the volatilization from water of 1,1,1-trichloroethane and 1,2-dichloroethane were measured in a stirred tank. Experiments at constant mixing conditions over a wide range of concentrations showed that the volatilization coefficient was independent of concentration, confirming the assumption that volatilization is a first order process. Simultaneous measurements of the...
Red fox predation on breeding ducks in midcontinent North America
Alan B. Sargeant, Stephen H. Allen, Robert T. Eberhardt
1984, Wildlife Monograph 89
Red fox (Vulpes vulpes) predation on nesting ducks was assessed by examining 1,857 adult duck remains found at 1,432 fox rearing dens from 1968 to 1973. Dabbling ducks were much more vulnerable to foxes than diving ducks. Dabbling ducks (1,798) found at dens consisted of 27% blue-winged teals (Anas discors),...
The quality of ground water in the principal aquifers of northeastern-north central Washington
J.C. Ebbert
1984, Water-Resources Investigations Report 83-4102
In 1979 the quality of ground water in major aquifers in northeastern-north central Washington State was assessed in terms of inorganic-chemical, trace-metal, and fecal-coliform concentrations. For the Spokane Valley aquifer some organic-chemical data were also included. Results of this assessment indicate that the ground water in the region is generally...

Facies analysis of the Ludlow and Tongue River Members of the Palaeocene Fort Union Formation provides an understanding of the relationship between fluviodeltaic environments and associated coal deposition in the south-western Williston Basin. The Ludlow Member consists of high-constructive delta facies that interfinger with brackish-water tongues of the...

Effect of censoring trace-level water-quality data on trend-detection capability
R. J. Gilliom, R.M. Hirsch, E.J. Gilroy
1984, Environmental Science & Technology (18) 530-535
Monte Carlo experiments were used to evaluate whether trace-level water-quality data that are routinely censored (not reported) contain valuable information for trend detection. Measurements are commonly censored if they fall below a level associated with some minimum acceptable level of reliability (detection limit). Trace-level organic data were simulated with best-...
Gold in natural water: A method of determination by solvent extraction and electrothermal atomization
J. B. McHugh
1984, Journal of Geochemical Exploration (20) 303-310
A method has been developed using electrothermal atomization to effectively determine the amount of gold in natural water within the nanogram range. The method has four basic steps: (1) evaporating a 1-L sample; (2) putting it in hydrobromic acid-bromine solution; (3) extracting the sample with methyl-isobutyl-ketone; and (4) determining the...
Characterization of the oil shale of the New Albany Shale in Indiana
R. K. Leininger, J.G. Hailer, N.R. Shaffer
1984, Conference Paper, Preprints
In the 1920's chemical and mineralogic characterization of the New Albany Shale (Mississippian-Devonian) in Indiana showed the dark shale to be rich in organic material and have commercial possibilities. Projects in the 1960's resulted in disparaging descriptions of exiguous fossil record, monotonous mineralogy, and intractable chemistry. Since 1978 expanded efforts...

Use of dissolved oxygen modeling results in the management of river quality
D. A. Rickert
1984, Journal of the Water Pollution Control Federation (56) 94-101
In 1973, the U.S. Geological Survey initiated a study of the Willamette River, Oregon, to determine the major causes of dissolved oxygen (DO) depletion, and whether advanced treatment of municipal wastewaters was needed to achieve the DO standards. The study showed that rates of carbonaceous decay were low (kr =...

1984, Water-Resources Investigations Report 83-4273
A water-level contour map of the Carpinteria area, California, has been completed by the U.S. Geological Survey using 34 water-level measurements made by the Carpinteria County Water District in March 1982. Also shown are 5 hydrographs that show water-level fluctuations in each well between 1977 and 1982....
Sampling design optimization for spatial functions
Ricardo A. Olea
1984, Journal of the International Association for Mathematical Geology (16) 369-392
A new procedure is presented for minimizing the sampling requirements necessary to estimate a mappable spatial function at a specified level of accuracy. The technique is based on universal kriging, an estimation method within the theory of regionalized variables. Neither actual implementation of the sampling nor universal kriging estimations are...
Interactions of solutes and streambed sediment: 2. A dynamic analysis of coupled hydrologic and chemical processes that determine solute transport
Kenneth E. Bencala
1984, Water Resources Research (20) 1804-1814
Solute transport in streams is determined by the interaction of physical and chemical processes. Data from an injection experiment for chloride and several cations indicate significant influence of solutestreambed processes on transport in a mountain stream. These data are interpreted in terms of transient storage processes for all tracers and...

Land subsidence near oil and gas fields, Houston, Texas
T.L. Holzer, R.L. Bluntzer
1984, Groundwater (22) 450-459
Subsidence profiles across 29 oil and gas fields in the 12,200-km2 Houston, Texas, regional subsidence area, which is caused by decline of ground-water level, suggest that the contribution of petroleum withdrawal to local land subsidence is small. Despite large volumes of petroleum production, subsidence at most...
Ferromanganese nodules from MANOP Sites H, S, and R-Control of mineralogical and chemical composition by multiple accretionary processes
J. Dymond, M. Lyle, B. Finney, D.Z. Piper, K. Murphy, R. Conard, N. Pisias
1984, Geochimica et Cosmochimica Acta (48) 931-949
The chemical composition of ferromanganese nodules from the three nodule-bearing MANOP sites in the Pacific can be accounted for in a qualitative way by variable contributions of distinct accretionary processes. These accretionary modes are:1.(1) hydrogenous, i.e., direct precipitation or accumulation of colloidal metal oxides in seawater,2.(2)...

A neutron generator pulsed at 100 s-1 was suspended in an artificial borehole containing a 7.7 metric ton mixture of sand, aragonite, magnetite, sulfur, and salt. Two Ge(HP) gamma-ray detectors were used: one in a borehole sonde, and one at the outside wall of the sample tank opposite the neutron...
The occurrence and behavior of radium in saline formation water of the U.S. Gulf Coast region
T. F. Kraemer, D.F. Reid
1984, Chemical Geology (46) 153-174
Radium has been measured in deep saline formation waters produced from a variety of U.S. Gulf Coast subsurface environments, including oil reservoirs, gas reservoirs and water-producing geopressured aquifers. A strong positive correlation has been found between formation-water salinity and Ra activity, resulting from the interaction of formation water with aquifer...
