The second well-field arrangement allowed comparison of drawdown between the initial well-field arrangement and (a) wells located 350 feet (107m) nearer the river, (b) additional wells, located between the initial well field and the bedrock valley wall and (c) wells located on a line perpendicular to the river rather than parallel to the river.

The chemical analyses included constituents of three general classes: (1) nutrients, (2) activity indicators, and (3) dominant anions. Modification of the natural chemical and physical characteristics of the surface waters by man's activities is evident in some of the data. However, the activities are so diverse in type and in areal extent that their influence in terms of cause and effect is often obscure.</p>\n<br>\n<p>Nutrient concentrations were high enough to indicate potential problems at about a quarter of the sampling sites. Temperature, dissolved oxygen, and pH values indicated a generally favorable capacity for regeneration or recovery from degradation, although a number a streams east of the Allegheny and Monongahela Rivers are marginal or lacking in the capacity. Regionally, sulfate is the dominant ion and was observed in concentrations of 40 milligrams per litre or more at 90 percent of the sites. Bicarbonate exceeded 100 milligrams per litre at 22 sites. A moderate to high degree of mineralization, as indicated by conductance readings of more than 500 micromhos per cetrimetre at half of the sampling sites, is a characteristic of the region's surface waters.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri7450","usgsCitation":"Beall, R.M., 1975, Stream reconnaissance for nutrients and other water-quality parameters, Greater Pittsburgh Region, Pennsylvania: U.S. Geological Survey Water-Resources Investigations Report 50-74, Report: iv, 47 p.; 2 Plates: 16.60 x 21.93 inches and 13.75 and 16.71 inches, https://doi.org/10.3133/wri7450.","productDescription":"Report: iv, 47 p.; 2 Plates: 16.60 x 21.93 inches and 13.75 and 16.71 inches","numberOfPages":"54","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":286676,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":286673,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1974/0050/plate-1.pdf"},{"id":286674,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1974/0050/plate-2.pdf"},{"id":286675,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1974/0050/report.pdf"}],"scale":"500000","country":"United States","state":"Pennsylvania","otherGeospatial":"Greater Pittsburgh Region","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -80.5,39.75 ], [ -80.5,41.25 ], [ -78.75,41.25 ], [ -78.75,39.75 ], [ -80.5,39.75 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a5141","contributors":{"authors":[{"text":"Beall, Robert M.","contributorId":90695,"corporation":false,"usgs":true,"family":"Beall","given":"Robert","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":195857,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Using a release-flow model and an empirical equation, the suspended-sediment discharge at Kneeland was estimated to be about 60 percent of the suspended-sediment discharge at the Arcata station. The study of the proposed impoundment determined the effect of discharge on channel configuration and concluded: The reservoir would trap about 60 percent of the potential beach-forming sediments. Release flows could transport'the expected inflow of sediment particles less than 2 millimetres in diameter for the reach of the river downstream from the impoundment site and about 130,000 tons per year (120,000 tonnes per year) of bed material particles less than 3 inches (76 millimetres) in diameter. Release flows could be expected to degrade the channel for about 15.miIes (24 kilometres) downstream from the impoundment, and downstream from that reach artificial adjustments would override most release-flow effects on channel adjustments.

Evaporation in this arid basin exceeds the 4 inches (100 millimetres) of annual precipitation. Fifteen test holes, ranging in depth from 40 to 240 feet (12 to 73 metres) below land surface, indicate that ground water occurs mostly in Tertiary volcanic and sedimentary rocks overlying pre-Tertiary quartz monzonite. Depth to water averages about 100 feet (30 metres) below land surface. Hydraulic conductivity of cores of Tertiary rock taken from a test hole at depths of 9 to 88 feet (2.7 to 27 metres) below land surface suggests values of 6.9 x 10-5 to 4.9 x 10<sup>-3</sup> feet per day (2.1 x 10<sup>-5</sup> to 1.5 x 10<sup>-3</sup> metres per day). Petrographic analyses of these cores indicate a material consisting mostly of weathered volcanic rocks with a moderate concentration of montmorillonite clay.</p><p>The water-level gradient averages about 4 feet per mile (0.76 metre per kilometre). Ground-water discharge through a narrow gap in the southeastern part of the basin is calculated to be 3.8 x 10<sup>-4</sup> acre-feet (4.7 x 10<sup>-7</sup> cubic hectometres) per year. After leaving the basin, the underflow becomes part of a regional flow system discharging into Harper Lake playa.</p><p>An increase in the underflow from 3.8 x 10<sup>-4</sup> acre-feet (4.7 x 10<sup>-7</sup> cubic hectometres) per year to 3 acre-feet (4 x 10<sup>-3</sup> cubic hectometres) per year may result in an undesirable surface-water flow by increasing the saturated thickness of the aquifer near the narrow gap in the southeastern part of the basin. Also, the very low hydraulic-conductivity values suggest that some difficulties may exist in percolating 3 acre-feet (4 x 10<sup>-3</sup> cubic hectometres) per year of wastes resulting in possible saturation of the ground surface outside the boundaries of the potential Class-I site. Because the rate of evaporation is very high (116 inches or 294.6 millimetres per year) in the study area, many of the problems associated with the percolation of the waste water and the subsequent changes in ground-water movement could be minimized by evaporating the wastes to complete dryness.</p><p>The quality of the ground water in the basin is generally unsuitable for domestic, industrial, and irrigation purposes. The concentration and type of chemical constituents in the ground water suggest slow circulation in a geologic environment with soluble minerals.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri757","usgsCitation":"Hughes, J.L., 1975, Hydrologic evaluation of the Haystack Butte area : with emphasis on possible discharge of class-I wastes, Edwards Air Force Base, California: U.S. Geological Survey Water-Resources Investigations Report 75-7, iv, 34 p., https://doi.org/10.3133/wri757.","productDescription":"iv, 34 p.","costCenters":[],"links":[{"id":158606,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1975/0007/report-thumb.jpg"},{"id":358950,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1975/0007/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","otherGeospatial":"Edwards Air Force Base, Haystack Butte area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.63473510742186,\n              34.82282272723702\n            ],\n            [\n              -117.49740600585936,\n              34.82282272723702\n            ],\n            [\n              -117.49740600585936,\n              34.96474810049312\n            ],\n            [\n              -117.63473510742186,\n              34.96474810049312\n            ],\n            [\n              -117.63473510742186,\n              34.82282272723702\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1ae4b07f02db606db9","contributors":{"authors":[{"text":"Hughes, Jerry L.","contributorId":19944,"corporation":false,"usgs":true,"family":"Hughes","given":"Jerry","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":198696,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The local ground-water flow system is dominated by an outwash aquifer that is sandwiched between two till layers in the western part of the area and exposed at the land surface in the eastern part. Ground water discharges from the aquifer into lakes in the outwash area but is recharged from lakes in the till-covered area. Irregular aquifer geometry resulted in a complex ground-water flow system. Simulation of the system by areal and vertical-section models showed that the lakes significantly control groundwater flow near their boundaries. Inadequate field data and complex geology caused difficulty in obtaining solutions with the vertical-section model. The models may be used to guide collection and interpretation of field data, and quantification of the ground-water flow system. With modification, they could be used to predict aquifer response to transient stresses. They also could be incorporated into more complex models to determine the movement of solutes in the ground-water system.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"St. Paul, MN","doi":"10.3133/wri7540","collaboration":"Prepared in cooperation with the U.

Although the Develco discriminators were designed for this application and a matching Develco compensation discriminator was purchased, effective use of this system for subtractive compensation has been blocked by the inadequate (frequency dependent) matching of the phase of the compensation signal to that of the data signal at the point compensation is carried out in the data discriminators. John Van Schaack has ameliorated the phase mismatch problem by an empirical alteration of the compensation discriminator input bandpass filter. We have selected a set (of eight) Develco discriminators and adjusted their compensation signal input levels to minimize spurious signals (noise) originating from tape speed irregularities. The sensitivity of the data discriminators was adjusted so that deviations of +125 Hz and -125 Hz produced output signals of +2.00 volts and -2.00 volts, respectively. The eight data discriminators are driven by a multiplex signal on a single tape track (subcarriers 680, 1020, 1360, 1700, 2040, 2380, 2720, and 3060 Hz). The Develco-supplied compensation discriminator requires an unmodulated 3125 Hz signal on a separate tape track.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr75663","usgsCitation":"Eaton, J.P., 1975, Notes on some experiments on the application of subtractive compensation to USGS seismic magnetic tape recording and playback systems: U.S. Geological Survey Open-File Report 75-663, ii, 36 p., https://doi.org/10.3133/ofr75663.","productDescription":"ii, 36 p.","onlineOnly":"Y","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true},{"id":379,"text":"Menlo Park Science Center","active":false,"usgs":true}],"links":[{"id":142676,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_75_663.gif"},{"id":257112,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1975/0663/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afce4b07f02db6969dc","contributors":{"authors":[{"text":"Eaton, Jerry P.","contributorId":22341,"corporation":false,"usgs":true,"family":"Eaton","given":"Jerry","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":158158,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Part of the rainfall (about 1,130 mgd or 50 m<sup>3</sup>/s) runs off directly into streams, and the remaining 1,690 mgd (74 m<sup>3</sup>/s) replenishes soil moisture to underground reservoirs.</p><p>Potential sources of ground water in the county are limestone, dolomite, sandstone, and chert aquifers. Wells developed in these aquifers may produce as much as 0.5 mgd (0.022 m<sup>3</sup>/s) per well. In some areas, wells developed in the limestone, dolomite, and chert aquifers may produce more than 0.5 mgd (0.022 m<sup>3</sup>/ s) per well.</p><p>Potential sources of surface water in Jefferson County are the Black Warrior and Cahaba Rivers, Locust Fork, and Valley, Village, Fivemile, Shades, and Turkey Creeks. Average flows at the mouth of these streams or at the point where the stream leaves the county are 4, 070, 250, 1, 230, 360, 100, 120, 100, and 90 mg (178, 11, 54, 16, 4.4, 5. 3, 4. 4, and 3.9 m<sup>3</sup>/s), respectively. Low flows (7-day Q<sub>2</sub>) are generally in the range of 10 to 100 mgd (0. 44 to 4.4 m<sup>3</sup>/s). Most streams, however, are affected in some way by urbanization. These effects must be considered and better defined before extensive use of streamflow is made.</p><p>Water from the limestone and dolomite aquifers generally is moderately hard to very hard, contains less than 0.3 mg/1 (milligrams per liter) iron, and has 3 median value of 150 mg/1 dissolved solids. Water from the sandstone aquifer generally is soft to moderately hard, contains iron in excess of 0.3 mg/1, and has a median value of 210 mg/1 dissolved solids.</p><p>The concentrations of mineral constituents of surface water generally become progressively greater in the downstream direction. The increase in concentration of mineral constituents is attributed to inflow of municipal and industrial waste in the downstream reaches of the stream.

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 of other waste-management practices. As a result, summer dissolved-oxygen levels have increased, salmon runs have returned, and the overall effort is widely regarded as a singular water-quality success. To document the improved dissolved-oxygen regimen, the U.S. Geological Survey conducted intensive studies of the Willamette during the summer low-flow seasons of 1973 and 1974. During each summer the mean daily dissolved-oxygen levels were found to be higher than 5 milligrams per liter throughout the river. Because of the basinwide secondary treatment, carbonaceous deoxygenation rates were low. In addition, almost half of the biochemical oxygen demand entering the Willamette was from diffuse (nonpoint) sources rather than outfalls. These results indicated that point-source biochemical oxygen demand was no longer the primary cause of dissolved-oxygen depletion. Instead, the major causes of deoxygenation were nitrification in a shallow ' surface active ' reach below Salem and an anomalous oxygen demand (believed to be primarily of benthal origin) in Portland Harbor.

Within the Yakutat region are some of the tallest mountains, some of the heaviest snowfalls, and the largest glacier in North America. Between the abrupt mountain front and the Gulf of Alaska lies a very gently sloping plain of outwash derived from repeated cycles of advance followed by melt and retreat of glaciers during the Quaternary Period. The latest melting probably took place 500 to 600 years ago. Yakutat is built upon the moderately steep moraine that is the product of melting of one of these glaciers. Near Yakutat, surficial deposits are as much as 700 feet thick and probably overlie siltstone, sandstone, and mudstone. The eight general categories of mapped surficial deposits include artificial fill, organic, eolian, beach, delta-estuarine, alluvial, and outwash deposits, and deposits of the outer Yakutat Bay moraine complex.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr75529","usgsCitation":"Yehle, L.A., 1975, Preliminary report on the reconnaissance engineering geology of the Yakutat area, Alaska, with emphasis on evaluation of earthquake and other geologic hazards: U.S. Geological Survey Open-File Report 75-529, Report: iv, 136 p.; 2 Plates: 17.55 x 23.84 inches and 23.76 x 22.10 inches, https://doi.org/10.3133/ofr75529.","productDescription":"Report: iv, 136 p.; 2 Plates: 17.55 x 23.84 inches and 23.76 x 22.10 inches","costCenters":[],"links":[{"id":419431,"rank":4,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0529/figure-2.pdf","text":"Figure 2","linkFileType":{"id":1,"text":"pdf"}},{"id":419430,"rank":3,"type":{"id":29,"text":"Figure"},"url":"https://pubs.usgs.gov/of/1975/0529/figure-4.pdf","text":"Figure 4","linkFileType":{"id":1,"text":"pdf"}},{"id":419427,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0529/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":150377,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0529/report-thumb.jpg"}],"scale":"63360","country":"United States","state":"Alaska","otherGeospatial":"Yakutat area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -140.46791499075454,\n              59.89062741426659\n            ],\n            [\n              -140.46791499075454,\n              59.494396417496176\n            ],\n            [\n              -139.5015327447604,\n              59.494396417496176\n            ],\n            [\n              -139.5015327447604,\n              59.89062741426659\n            ],\n            [\n              -140.46791499075454,\n              59.89062741426659\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aaee4b07f02db66c788","contributors":{"authors":[{"text":"Yehle, Lynn A. yehle@usgs.gov","contributorId":3794,"corporation":false,"usgs":true,"family":"Yehle","given":"Lynn","email":"yehle@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":173258,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

As petroleum reservoirs they commonly have poor performance histories. They contain the sediments of a depositional system comprised of three closely associated depositional subenvironments: dune, interdune, and extradune. Sediments of each subenvironment have different textural properties which resulted from different depositional processes. Dune sediments are usually more porous and permeable than interdune or extradune sediments and may be better quality reservoirs than interdune or extradune sediments. Interdune sediments are here restricted to those nondune sediments deposited in the relatively flat areas between dunes. Extradune sediments (a new term) include all deposits adjacent to a dune field and are mainly subaqueous deposits. Dune sediments may be enveloped by extradune sediments as the depositional system evolves resulting in a texturally inhomogeneous reservoir having poor fluid migration properties.\r\n\r\nThis model of textural inhomogeneity in eolian blanket sandstones. was applied to the Weber (Tensleep) Sandstone in Brady, Wertz, and Lost Soldier fields, Sweetwater County, Wyoming. Data were obtained from both outcrop and subsurface and included environmental interpretation, textural analysis, and plotting of the distribution of depositional subenvironments. As predicted from the model, the texture of dune sediments in Brady field differed markedly from interdune and extradune sediments. The predicted geometric distribution of subenvironments was confirmed in Lost Soldier and Wertz fields. However, secondary cementation and fracturing there has obscured the original porosity and permeability contrasts. The porosity and permeability distribution, a characteristic depending partly on depositional processes, could impede fluid migration in the reservoir and significantly reduce recovery of hydrocarbons.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr75363","usgsCitation":"Wrucke, C.T., 1975, Lithology and chemical analyses of core and cuttings from USGS drill hole near Gold Acres, Lander County, Nevada: U.S. Geological Survey Open-File Report 75-363, 28 leaves :map ;27 cm., https://doi.org/10.3133/ofr75363.","productDescription":"28 leaves :map ;27 cm.","costCenters":[],"links":[{"id":149518,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1975/0363/report-thumb.jpg"},{"id":45693,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1975/0363/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db635c16","contributors":{"authors":[{"text":"Wrucke, Chester T.","contributorId":21145,"corporation":false,"usgs":true,"family":"Wrucke","given":"Chester","email":"","middleInitial":"T.","affiliations":[],"preferred":false,"id":173220,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
