Gravity data were obtained from 460 stations in Carson Valley, Nevada and California. The data have been interpreted to obtain a map of approximate depth to bedrock for use in a ground-water model of the valley. This map delineates the shape of the alluvium-filled basin and shows that the maximum depth to bedrock exceeds 5,000 feet, on the west side of the valley. A north-south trending offset in the bedrock surface shows that the Carson-Valley/Pine-Nut-Mountain block has not been tilted to the west as a simple unit, but is comprised of several smaller blocks.

Average bed thicknesses, in descending order, are 5, 5, 9, and 8 .feet. In the area between Stony Creek and Crazy Man Coulee, the lignite beds are unsaturated, and between Stony Creek and Little Muddy River, only the two lowest beds are saturated. Natural discharge to outcrops in the stream valleys results in low potentiometric levels in the lignite beds.
Aquifers in sandstone beds in the Fox Hills Sandstone and the Hell Creek Formation probably would yield as much as 50 gallons per minute of sodium bicarbonate type water. Dissolved-solids concentrations range from 800 to 2,000 milligrams per liter. The aquifers are from 1,100 to 1,800 feet below land surface. Sandstone beds in the Ludlow and Cannonball Members of the Fort Union Formation probably could yield several gallons per minute of sodium bicarbonate water with dissolved-solids concentrations ranging from 800 to 2,000 milligrams per liter. Aquifers in the Ludlow and Cannonball Members lie between 700 and 1,300 feet below land surface. Individual sand beds in the Tongue River and Sentinel Butte Members of the Fort Union Formation are the shallowest aquifers encountered below the minable lignite beds. Properly constructed wells completed in these sand beds could yield as much as 40 gallons per minute. The water generally is a sodium bicarbonate type with dissolved-solids concentrations ranging from about 500 to 4,200 milligrams per liter. Alluvium and glacial-drift deposits constitute the Little Muddy aquifer bordering the lignite deposit on the west and south. The aquifer could yield as much as 1,200 gallons per minute of sodium bicarbonate type water with dissolved-solids concentrations ranging from 975 to 1, 730 milligrams per liter.
Little Muddy Creek and Stony Creek have significant base flow. The flow is contributed partly by discharge from the lignite. Quality of water is least mineralized at high stream flows. Mining would not severely affect ground-water levels because potentiometric levels already are low. Chemically enriched leachate water from the spoils could percolate to the saturated zone and eventually reach the streams as base flow or recharge the glaciofluvial aquifers.

The study area is underlain by rocks of Pennsylvanian age, the most important coal-producing formations of which are the Allegheny and Monogahela Formations.\r\n\r\nThe study area contains 276 data-collection sites, each of which was sampled four times over a 3-year period. Water and bed-material samples were collected. Each site was classified as 'abandoned,' reclaimed,' unmined,' or mixed,' depending on the proportion of the drainage basin disturbed by mining, and if mined, on the present condition of the mine. Of the 130 sites in the Monogahela Formation, 18 percent were classified as abandoned, 2 percent as reclaimed, 10 percent as unmined, and 70 percent as mixed. Of the 146 sites in the Allegheny Formation, 14 percent were classified as abandoned, 11 percent as unmined, and 75 percent as mixed.\r\n\r\nStreams draining the carbonate-bearing Monogahela Formation have a significantly greater buffering capacity than streams draining the Allegheny Formation. THere are significant differences in specific conductance; pH; alkalinity; acidity; hardness; total and dissolve manganese, and aluminum; dissolved nickel, zinc, and sulfate; and dissolved solids among mining-disturbance types in the Allegheny Formation. However, in stream draining the Monogahela Formation, only hardness, sulfur, dissolved solids, and dissolved manganese are significantly different among mining-disturbance types.\r\n\r\nDiscriminant-function analysis of water-quality data was used to classify each 'mixed' site into one of four categories: Abandoned, reclaimed, unmined, or uncertain. In addition, observations in each of the first three categories were classified as strongly, moderately, or weakly characteristic of that category. The discriminant function was based on specific conductance, pH, acidity, dissolved sulfate, dissolved aluminum and dissolved manganese in streams draining the Allegheny Formation, and was based on specific conductance, dissolved sulfate, and alkalinity for streams draining the Monogahela Formation.\r\n\r\nOf the 'mixed' sites in the Monogahela Formation, 46 percent were reclassified as abandoned, 11 percent as reclaimed, 18 percent as unmined, and 24 percent as uncertain. One site was not classified because of insufficient data. Of the 'mixed' sites in the Allegheny Formation, 27 percent were reclassified as abandoned, 57 percent as unmined, and 15 percent as uncertain. Four sites were not classified because of insufficient data.","language":"ENGLISH","publisher":"U.S. Geological Survey, Water Resources Division,","doi":"10.3133/wri844212","usgsCitation":"Childress, C., 1985, Classification of stream basins in southeastern Ohio according to extent of surface coal mining: U.S. Geological Survey Water-Resources Investigations Report 84-4212, iv, 83 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri844212.","productDescription":"iv, 83 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":126872,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1984/4212/report-thumb.jpg"},{"id":57796,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1984/4212/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e47c8e4b07f02db4ababe","contributors":{"authors":[{"text":"Childress, C.J.","contributorId":88734,"corporation":false,"usgs":true,"family":"Childress","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":200625,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":13920,"text":"ofr85744 - 1985 - Fracture history of the Plateau Creek and adjacent Colorado River valleys, southern Piceance Basin: Implications for predicting joint patterns at depth","interactions":[],"lastModifiedDate":"2022-12-21T19:19:47.949581","indexId":"ofr85744","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1985","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"85-744","title":"Fracture history of the Plateau Creek and adjacent Colorado River valleys, southern Piceance Basin: Implications for predicting joint patterns at depth","docAbstract":"No abstract available.

The study, done in cooperation with the City of Bellevue, was part of the U.S. Environmental Protection Agency 's National Urban Runoff program. The objectives of the study were to (1) establish a consistent and accessible data base for typical urban watersheds; (2) determine the magnitude and frequency of storm-runoff loads of water-quality constituents from three catchments in the city; (3) develop methods for estimating storm and annual loads of water-quality constituents from unsampled catchments in the study area; and (4) test the effectiveness of storm-water-quality management alternatives, such as street sweeping and detention storage, for the attenuation of constituent loads carried in storm runoff. This report presents data collected during the study period. Data include rainfall and runoff amounts, physical characteristics of the catchments, the chemical quality of storm runoff and in wet- and dry-atmospheric deposition, constituent loads in storm runoff and in wet- and dry-atmospheric deposition, and storm characteristics data, such as rainfall and runoff volumes.

Ground waters in each of these systems evolve from low dissolved-solids concentration, near-neutral pH, predominantly calcium and magnesium bicarbonate types in their recharge areas, to high dissolved-solids concentration, high pH, predominantly sodium-bicarbonate types in the basins. Oxidation potentials decrease as the waters flow downgradient under confined conditions. Calculation of the saturation states of aquifer minerals suggests several groups of mineral phases that could control ground-water chemistry. Mass transfer modeling indicates, however, that the observed behavior of major and minor dissolved species in both systems can satisfactorily be explained only by equilibration with calcite, dolomite, or calcite and dolomite. The geochemistry of these systems is probably controlled by the incongruent dissolution of dolomite to form calcite. This reaction appears to be driven by cation exchange and the dissolution of carbon dioxide. Plausible carbon dioxide sources include organic carbon oxidation and lignite coalification. Aluminosilicates influence major element chemistry primarily as subtrates for cation exchange, which, in combination with carbonate equilibria, buffer ground water pH at values of 8.5 to 8.9. Dissolved-iron concentrations are controlled by equilibration with amorphous ferric oxyhydroxides in oxidizing waters, with amorphous ferric oxyhydroxides and siderite in moderately reducing waters, and with siderite and amorphous ferrous sulfide in strongly reducing waters. Measured variations in dissolved carbonate isotopic composition compare favorably with carbon isotopic evolution, calculated by assuming dedolomitization.
Recharge areas of the two systems are characterized by ground waters with high tritium and carbon-14 activities and relatively low dissolved-solids concentrations, with calcium and magnesium as the predominant cations. Recharge temperatures, calculated from dissolved-argon concentrations and 5180 and SD isotopic measurements, indicate that recharge is derived primarily from spring snow-melt rather than late spring and summer storms. Ground-water flow directions are generally parallel to trends of increasing dissolved solids concentrations and decreasing divalent to monovalent cation concentration ratios. However, these trends are sometimes obscured in areas of leakage or mixing. Further indication of leakage between aquifers is provided by abrupt changes in major element and isotopic chemistry, which are not characteristic of normally observed geochemical evolution. Ground-water flow rates, calculated by adjusting measured carbon-14 activities for carbonate mass transfer, are comparable to values calculated from aquifer tests and potentiometric data. These carbon-14 flow rates average 1.6 meters per year for the Second Cat Creek sandstone of the Kootenai Formation, and 1.3 meters per year for the Lance-Fox Hills aquifer.

Studies are now in progress in Austin, and Houston. Studies have been completed in the Dallas, Fort Worth, and San Antonio areas.
\nThe Geological Survey, in cooperation with the Texas Department of Water Reources, began hydrologic studies in the Austin urban area in 1954. In cooperation with the city of Austin, the program was expanded in 1975 to include additional streamflow and rainfall gaging stations, and the collection of surface water-quality data. In 1978, the program was expanded to include a ground-water resources study of the South Austin metropolitan area in the Balcones Fault Zone.
\nThe objectives of the Austin urban hydrology study are as follows:
\nThis report presents the basic hydrologic data collected in the Austin urban area for the 1983 water year (Oct. 1, 1982 to Sept. 30, 1983).

The CDSN, which is being developed jointly by the PRC State Seismological Bureau and the U.S. Geological Survey, will consist initially of nine digitally-recording seismograph stations, a data management system to be used for compiling network-day tapes, and a depot maintenance center. Data produced by the network will be shared with research scientists throughout the world.
A national seismograph network must be designed to support a variety of research objectives. From this standpoint, the choices and tradeoffs involved in specifying signal bandwidth, resolution, and dynamic range are the most important decisions in system design. As in the case of the CDSN, these decisions are made during the selection and design of the seismic sensor system and encoder components. The purpose of this report is to describe the CDSN sensor systems, their important signal characteristics, and the results of preliminary tests that have been performed on the instruments.
Four overlapping data bands will be recorded at each station: short period (SP), broadband (BB), long period (LP), and very long period (VLP). Amplitude response curves are illustrated in Figure I. Vertical and horizontal components will be recorded for each data band. The SP and LP channels will be recorded with sufficient sensitivities to resolve earth background noise at seismically quiet sites. The BB channels will have a lower sensitivity and are intended for broadband recording of moderate-to-large body-wave signals and for increasing the effective amplitude range in the short- and long-period bands. The VLP channel does not provide additional spectral coverage at long periods; its purpose is to make use of on-site filtration and decimation to reduce post processing requirements for VLP studies. Early plans also included a triaxial set of low-sensitivity accelerometers for recording strong signals from large local and regional earthquakes. The accelerometers are not being installed; however, they may be added in the future.
The short-period signals will be derived from a three-component set of PRC-supplied Model DJ-I SP seismometers and US-supplied SP amplifiers. The seismometers will be installed in surface or shallow subsurface vaults, except at two of the stations where they will be installed in boreholes. The BB, LP, and VLP signals will be derived from Streckeisen STS-1 broadband sensor systems installed in vaults, except at one site where the LP signals only will-be derived from a KS-36000 borehole seismometer installed at a depth of 100 meters.
Analog signals will be sampled and quantized by an analog-to-digital converter (ADC) that is part of the recording system. Sampling rates chosen for the CDSN are as follows:
* SP 40 samples/second
* BB 20 samples/second
* LP 1 sample/second
* VLP 6 samples/minute
The ADC 16-bit data word format makes use of 14 bits to quantize the signal and 2 bits to specify an automatically ranged gain of 1, 8, 32, or 128. This will provide 84 dB of resolution and up to 42 dB of gain ranging for a total opera- ting range of 126 dB peak to peak.
Magnetic tape cartridges, each having a capacity of 67 megabytes, will be used for recording the digital data. LP and VLP data will be recorded continu- ously. SP and BB data will be processed through an automatic signal detector of the type described by Murdock and Hutt (1983), and only detected events will be stored on tape. Detection parameters, such as turn-on sensitivity and mini- mum recording duration for the SP and BB channels, will be fully programmable and easily changed. One or more of the data channels may also be recorded on analog recorders.
A CDSN recording system was not available at the time that the preliminary tests were performed on the CDSN sensor systems. This did not interfere with the principal goals of the testing which were to determine the best sensor installation techniques and to demonstrate the operational performance of the sensor systems, especially with regard to instrument noise and detection capability. When the CDSN recording system is available, additional tests will be performed to measure distortion levels in the full system and components. Distortion tests have been performed on the Streckeisen STS-1 broadband seismometers, the most critical component from the standpoint of linearity, and the results of the tests are reported by Wielandt and Streckeisen (1982). Calibration accuracy and stability are also important sensor system characteristics that cannot be defined without additional testing. These tests will be performed as the instruments are installed at the stations and periodically during operation.

Sodium bicarbonate type water is less common. Isolated areas of sodium chloride and calcium sulfate types also are present. The water is predominantly very hard, and has a median hardness concentration of 258 milligrams per liter as calcium carbonate and a median dissolved-solids concentration of 436 milligrams per liter. Few wells contain water with dissolved-solids concentrations in excess of 1,000 milligrams per liter.\r\n\r\nBicarbonate concentration in ground water was found to be significantly different among coals, whereas concentrations of bicarbonate, hardness, calcium, magnesium, sodium, iron, manganese, and strontium were significantly different between ground water in the Allegheny and Monongahela Formations. Many constituents are significantly correlated, but few correlation coefficients are high.\r\n\r\nThe presence of sulfate or iron is attributed to the kinetic mechanism operating during the oxidation of pyrite. The position along the sulfide or ferrous-iron oxidation pathways controls the reaction products of pyrite found in solution, and the formation of either the sulfate of iron constituents. The availability and rate of diffusion of oxygen in the formations exerts control on the water quality.\r\n\r\nDiscriminant-function analysis correctly classifies 89 percent of the observations into the Allegheny or Monongahela Formations. As a verifications, 39 of 41 observations from another study were correctly classified by formation.\r\n\r\nThe differences in water chemistry between the Allegheny and the Monongahela Formations are gradational and are attributed the oxidation of iron sulfide. The diffusion and availability of oxygen, which controls the chemical reaction, is regulated by the porosity and permeability of the rock with respect to oxygen and the presence or absence of carbonates, which controls the pH.","language":"ENGLISH","publisher":"Water Resources Division, U.S. Geological Survey,","doi":"10.3133/wri854034","usgsCitation":"Razem, A., and Sedam, A., 1985, Ground-water quality and geochemistry of aquifers associated with coal in the Allegheny and Monongahela formations, southeastern Ohio: U.S. Geological Survey Water-Resources Investigations Report 85-4034, iv, 39 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri854034.","productDescription":"iv, 39 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":122660,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1985/4034/report-thumb.jpg"},{"id":58132,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1985/4034/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a82e4b07f02db64ad69","contributors":{"authors":[{"text":"Razem, A.
