St. George basin is a long (300 km), narrow (30-50 km) graben whose long axis strikes northwestward, parallel to the continental margin of the southern Bering Sea. Located near the Pribilof Islands, and beneath the virtually featureless Bering Sea shelf, the basin is filled with more than 10 km of sedimentary deposits. These sedimentary rocks are ruptured by normal faults associated with the sides of the graben; these ruptures commonly correlate with offsets in the basement surface. Offset along these faults increases with depth implying that they are growth-type structures. Basement rocks, that floor and flank St. George basin are part of an assemblage of Mesozoic eugeosynclinal rocks that extends from southern Alaska to eastern Siberia beneath the Bering Sea margin and outer shelf. A parallel belt of igneous rocks of late Mesozoic and earliest Tertiary age may also extend from western Alaska to northeastern Siberia beneath the inner Bering Sea shelf.
The Bering Sea margin and adjacent shelf were apparently uplifted by the end of Mesozoic time, resulting in deep subaerial erosion• Following uplift, the outer Bering Sea shelf has undergone extensional rifting and regional subsidence. Differential subsidence has resulted in the formation of a series of basement ridges and basins whose axes parallel the Bering Sea margin. Some of these basins are very large to gigantic in size, e.g., St. George basin, and involve crustal subsidence exceeding 10 km. Such large scale crustal collapse suggests deep crustal or upper mantle processes, such as thermal metamorphism or stress-induced crustal migration.
Nine wells drilled along the northern coast of the Alaska Peninsula, as well as several onshore Soviet wells in northeastern Siberia, relate directly to the submerged basins of the Bering Sea shelf. Although all of the wells on the Alaska Peninsula were abandoned as dry holes, shows of oil and gas were found. In addition, Soviet drilling resulted in the discovery of oil and gas
shows in Oligocene and Miocene sandstone.
Regional geologic and geophysical mapping suggests that there are suitable source beds, reservoir rocks, and traps within St. George basin. However, it is not known if hydrocarbons are present or if the possible reservoirs are of commercial size. A resource appraisal of St. George basin out to 200 meters water depth indicates that, at 5 percent probability, 6.4 billion barrels of oil and 18.6 trillion cubic feet of gas may be in the basin; at 95 percent probability 0.8 billion barrels of oil and 4.5 trillion cubic feet of gas may be in the basin. The statistical mean of the appraisal is 2.7 billion barrels of oil and 10.3 trillion cubic feet of gas.
A large number of faults, evidence for recent movement along some of the faults, and high seismicity all indicate that faulting is a major environmental concern for the outer continental shelf region of the southern Bering Sea, especially in St. George basin. Most of the faults are potentially active and their movement is probably influenced by the local geology, including basement structures and sediment loading. Unstable sediment masses pose potential threats to resource development in the vicinity of the Pribilof Canyon. Volcanic activity along the Aleutian arc south of St. George basin may also pose an environmental hazard to petroleum development in the area. Another environmental hazard is the presence of shallow gas pockets, which could pose such problems during drilling as blowouts and liquefaction of bottom sediment.
This report summarizes geological and geophysical data from the deep-water (greater than 200m) region of the St. George Basin lease sale area #70. The shallow-water region is discussed in detail by Marlow and others (1979a) in a companion report. The triangular deep-water region lies at the junction of the Bering shelf and the Aleutian Ridge (Fig. 2). This region is bounded on the northeast by the 200 m bathymetric contour that defines the edge of the Bering shelf, on the southeast by a meandering line that lies 3 miles north of the Aleutian Islands, and on the west by the 171°W longitude meridian. Hereafter, this triangular region is referred to as the Umnak Plateau region. The name is derived from a major bathymetric feature, Umnak Plateau, that covers most of the region.

Samples from Yellowstone National Park has been omitted because they were discussed by McKenzie and Truesdell (1974).

compiled to update and summarize the geological information concerning the area of the Atlantic continental margin off the U.S. Mid-Atlantic proposed for Oil and Gas Lease Sale No. 59 (fig. 1). The region of interest lies between 35° and 41° N and 70.5° and 76° W. The north-south dimension is about 660 km (356 nautical miles, 410 statute miles) and the maximum east-west dimension is approximately 250 km (135 nautical miles, 155 statute miles). The area is centered toward the outer Continental Shelf off Delaware and contains more than 154,000 km2 (38,000,000 acres) off the coasts of North Carolina, Virginia, Maryland, Delaware, New Jersey and New York. Water depths within the region range from 20 to slightly more than 4,000 m (fig. 1).
This report begins with a discussion of the regional geology and geophysics, followed by a description of the oil and gas potential and potential environmental hazards.
Water samples collected in San Francisco Bay, the Gulf of the Farallones, and the delta of the Sacramento and San Joaquin rivers were analyzed for salinity, temperature, partial pressure of carbon dioxide (pCO2), chlorophyll a, alkalinity, particulate organic carbon (POC), and the stable carbon isotope ratio (δ13C) of the POC and total CO2. Water sampling occurred between January 1976 and March 1977. Bottom sediments for total organic carbon isotopic analyses (δ13C(TOC)) were collected during August 1973. Numerical values are tabulated, sampling locations are identified, and the analytical methods are briefly described.

Measured water-quality parameters were: salinity; temperature; turbidity; concentrations of selected dissolved gases (oxygen, carbon dioxide, methane, nitrous oxide, ethylene, ethane); concentrations of dissolved inorganic nutrients (ammonia, nitrate, nitrite, phosphate, silicate); and concentrations of chlorophyll a and phaeopigments, total coliforms, fecal coliforms, and fecal streptococci. Rates of oxygen utilization and photosynthetic production were measured at selected stations.

Part of the concern is related to the possible impacts that mining and processing of lignite will have on water resources. Not only will the disturbance caused by excavating affect the quantity and quality of surface and ground water but, the mining, processing, and conversion processes will require the use and consumption of significant quantities of water.
In order to assess the magnitude of the effects of strip mining upon both surface and ground water, baseline conditions (hydrologic conditions in the area prior to mining) must be well defined. A thorough data file and literature search was made so that baseline conditions in the area could be defined. In addition, data-collection networks have been established for the collection of quantitative and qualitative information on streamflow and water levels in the aquifers. Data collected to date at these sites are included in the report. Collection of data at these sites will continue through at least September 1979.
Information presented in this report can be used to estimate the quantities of water available for use and the possible effects of mining and associated dewatering on water resources.

Regional observations are coupled with a detailed diving and side-scan study of a single ice gouge of known age to develop a detailed description of the altered seabed conditions. Hydrodynamic activity has caused extensive sediment reworking, obliterating ice gouges to water depths of at least 13 m and has caused ponding of sediment in ice gouge terrain in deeper waters. Ponded sediment is characterized as a soft, sometimes very poorly consolidated, mud unit underlain by a stiffer, more consolidated, silty clay. In places, stiff silty clay is exposed in windows in the sediment pond and displays a fine-textured ice gouge morphology. Rates of sediment reworking and redisposition from apparently episodic events are an order of magnitude greater than the average sediment accumulation rates on the Beaufort Sea shelf. Reported maximum ice gouge incision depths are not representative of maximum ice keel penetrations into the seabed because these sedimentation events preferentially infill gouges. Furthermore, because these sedimentation events concentrate sediments in gouge troughs, a series of overlapping and interfingering 'shoestring' deposits is developed which should characterize the ice gouge stratigraphy. The specific hydraulic mechanisms for sediment redistribution and sediment compaction observed in this study are only poorly understood.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr79848","usgsCitation":"Barnes, P.W., and Reimnitz, E., 1979, Ice gouge obliteration and sediment redistribution event: 1977-1978, Beaufort Sea, Alaska: U.S. Geological Survey Open-File Report 79-848, 22 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr79848.","productDescription":"22 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":141239,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/0848/report-thumb.jpg"},{"id":35309,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/0848/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb850","contributors":{"authors":[{"text":"Barnes, Peter W.","contributorId":6042,"corporation":false,"usgs":true,"family":"Barnes","given":"Peter","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":156656,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reimnitz, Erk","contributorId":17963,"corporation":false,"usgs":true,"family":"Reimnitz","given":"Erk","email":"","affiliations":[],"preferred":false,"id":156657,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":7840,"text":"ofr791330 - 1979 - Sediment deposition in the White River Reservoir, northwestern Wisconsin","interactions":[{"subject":{"id":7840,"text":"ofr791330 - 1979 - Sediment deposition in the White River Reservoir, northwestern Wisconsin","indexId":"ofr791330","publicationYear":"1979","noYear":false,"title":"Sediment deposition in the White River Reservoir, northwestern Wisconsin"},"predicate":"SUPERSEDED_BY","object":{"id":999,"text":"wsp2069 - 1980 - Sediment deposition in the White River Reservoir, northwestern Wisconsin","indexId":"wsp2069","publicationYear":"1980","noYear":false,"title":"Sediment deposition in the White River Reservoir, northwestern Wisconsin"},"id":1}],"supersededBy":{"id":999,"text":"wsp2069 - 1980 - Sediment deposition in the White River Reservoir, northwestern Wisconsin","indexId":"wsp2069","publicationYear":"1980","noYear":false,"title":"Sediment deposition in the White River Reservoir, northwestern Wisconsin"},"lastModifiedDate":"2015-10-13T14:17:39","indexId":"ofr791330","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","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":"79-1330","title":"Sediment deposition in the White River Reservoir, northwestern Wisconsin","docAbstract":"The history of deposition in the White River Reservoir was reconstructed from a study of sediment in the reservoir. Suspended-sediment concentrations, particle size, and streamflow characteristics were measured at gaging stations upstream and downstream from the reservoir from November 1975 through September 1977- Characteristics of the sediments were determined from borings and samples taken while the reservoir was drained in September 1976. The sediment surface and the prereservoir topography were mapped. Sediment thickness ranged from less than 1 foot near the shore to more than 20 feet in the old stream channel.
\nThe original reservoir capacity and volume of deposited sediment were calculated to be 815 acre-feet and 487 acre-feet, respectively.
\nSediment size ranged from clay and silt in the pool area to large cobbles and boulders at the upstream end of the reservoir. Analyses of all samples averaged 43 percent sand, 40 percent silt, and 17 percent clay, and particle size typically increased upstream. Cobbles, boulders, and gravel deposits were not sampled. The average density of the deposited sediments was about 80 pounds per cubic foot for the entire reservoir.
\nThe reservoir was able to trap about 80 percent of the sediment entering from upstream early in its history. This trap efficiency has declined as the reservoir filled with sediment. Today (1976) it traps only sand and silt-sized sediment, or only about 20 percent of the sediment entering from upstream. Data collected during this study indicate that essentially all of the clay-sized sediment (<0.062 mm) passes through the reservoir.
\nThe gross rate of deposition was 7.0 acre-feet per year over the reservoir history, 1907-76. Rates during 1907-63 and 1963-76 were 7.4 and 5.7 acre-feet per year, respectively, determined by the Cesium-137 method.
\nBased on scant data, the average annual sediment yield of the total 279 square mile drainage area above the gaging station at the powerplant was about 50 tons per square mile. Analysis of the drainage-basin characteristics indicates that most of this sediment was derived from less than 10 percent of the total drainage area and from steep unvegetated streambanks.

The results of the study indicated that the chemical and physical properties and range of concentrations of several dissolved constituents in both estuaries varied during a tide cycle primarily as the result of the interaction of freshwater and wastewater inflow with the saline Gulf waters.
The water quality condition of both estuaries generally was good and the low 5-day biochemical oxygen demand in the estuaries indicated that excessive oxygen demand was not exerted during the study. The 5-day biochemical oxygen demand generally was less than 3.5 milligrams per liter. Dissolved-oxygen concentrations decreased with depths and the lowest concentrations occurred below 30-foot depths in Bayou Casotte. Oxygen levels at shallow depths generally were less in Bayou Chico than in Bayou Casotte. Dissolved-oxygen concentrations in Bayou Casotte ranged from 0.7 to 7.7 milligrams per liter at high tide and from 2.5 to 8.2 milligrams per liter at low tide. In general, phosphorus and nitrogen species were present in comparatively high concentrations in both estuaries; were higher at low tide that at high tide; and were highest in Bayou Casotte upstream of Bayou Casotte harbor. Concentrations of the nitrogen species during a tide cycle generally were lower at the mouth of Bayou Casotte than at the mouth of Bayou Chico. Fecal bacteria at most sampling sites were generally in concentrations indicative of recent manmade pollution.

The titles listed result from work undertaken in cooperation with national agencies partly through technical assistance projects under the auspices of the Agency for International Development, U.S. Department of State; partly under reimbursable assistance projects with other governments on behalf of the Department of State; partly under assistance projects sponsored by international organizations; and partly under scientific exchange projects supported by U.S. agencies such as the National Science Foundation.
This report includes titles published during the period 1975 through June 1979, but is not necessarily complete, as an exhaustive search was not made; however, it is being released in open file in order to make the data available to the public on an interim basis. Seven geographic regions and 71 countries are represented. A few titles published prior to 1975 have been found that are not included in Bulletins 1263 or 1426. Only reports authored solely or in part by USGS members, or jointly by USGS and counterpart staff members, are listed.
The reports are listed alphabetically by author, under the appropriate country; reports of wider scope are given under the continent or geographic region, for example, Africa, Central and South America, or CENTO region.

Millions of acre-feet of water is pumped from the system annually to support a large and expanding agribusiness industry. Since the 1950's, water levels have been steadily declining in many areas of the valley and concern has been expressed about the ability of the entire ground-water system to support agribusiness at current levels, not to mention its ability to function at projected expansion levels. At current levels of ground-water use, an estimated 1.5 to 2 million acre-feet is withdrawn from storage each year; that is, 1.5 to 2 million acre-feet of water is pumped annually in excess of annual replenishment. The U.S. Geological Survey has initiated a 4-year study to develop geologic, hydrologic, and hydraulic information and to establish a valleywide ground-water data base that will be used to build computer models of the ground-water flow system. Subsequently, these models may be used to evaluate the system response to various ground-water management alternatives. This report describes current problems, objectives of the study, and outlines the general work to be accomplished in the study area. A bibliography of about 600 references is included.

Eighty-three stream sites were selected for sampling in Eagle, Grand, Jackson, Pitkin, Routt, and Summit Counties. Also included are data from 28 sites in Routt County collected for a U.S. Geological Survey cooperative study on the Yampa River basin. A summary of data collected prior to this study, results of current chemical and biological sampling, and needs for future water-quality monitoring are reported for each county.
The kinds of data collected were site specific depending upon land-use activities. Data collected at selected sites included temperature, pH, specific conductance, dissolved oxygen, and stream discharge. Chemical data collected included nutrients, inorganics, organics, and trace elements. Biological data collected included counts and species composition of total and fecal-coliform bacteria, fecal-streptococcus bacteria, benthic invertebrates, and phytoplankton. Most of the sites were sampled three times: in April-June 1976, August 1976, and January 1977.
The major water-quality problems at the 17 sites sampled in Eagle County are related to mining, recreation, and geology. The Eagle River and Cross Creek in the vicinity of Minturn have concentrations of trace elements that exceed water-quality standards. Gore Creek is influenced by winter recreational use and the water during the winter has total bacteria counts as great as 72,000 per 100 milliliters and concentrations of un-ionized ammonia greater than 0.02 milligrams per liter downstream from the sewage-treatment plant. Mineralized water in the downstream reaches of the Eagle River results from natural chemical processes. The water-quality problems in Grand County, especially on the Fraser River, are related to recreation and urban activities. Chemical and biological indications of water-quality degradation exist for the Fraser River downstream from Winter Park.

Water in the area is derived from precipitation, which averages 12 inches annually, on three subbasins nearly surrounding the 17-square-mile reservation. No ground water flows in from outside the area. A supply well that taps sandy material overlying the pre-Tertiary basement complex showed a specific capacity of 0.4 gallon per minute per foot of drawdown. Estimates of specific yield for material encountered during drilling of three wells and a test hole ranged from 5 to 10 percent. A gravity survey outlined the thickest section of the aquifer in the Vandeventer Flat area, and test wells are proposed to determine its potential well yield. Damming streams to retain runoff (about 1,500 acre-feet per year, and more during periods of heavy precipitation) is also proposed. Analyses of water from the supply well and five major springs showed that ground water is suitable for irrigation except at Sulphur Spring, where the percent sodium of 97 exceeds recommended maximums, and at Bull Canyon Spring, where the specific conductance of 1,300 micromhos indicate a salinity hazard.

The calibrated model supported the hypothesis that under natural steady-state conditions, recharge is from precipitation and discharge is through evapotranspiration. This hypothesis was further supported by comparing simulated water levels to observed water levels collected during a 3-year period of irrigation withdrawal.
\nPredictions of the effects of continued withdrawal of currently allocated water were made. One prediction using recharge equal to 25 percent of the average annual precipitati on showed that an equilibrium between pumping and recharge would be established within 10 years and water levels would be 2 to 4 feet below 1977 levels . A second prediction included a 2-year drought of one -half the average recharge from precipitation. This prediction also showed equilibrium within 10 years, but water level s would be 3 to 5 feet below 1977 levels . Predictions using additional withdrawals based on allocation requests were inde terminate.

Larger reservoirs in the basin have varying effects on flows of rivers, ranging from complete flow control to minor regulation. \r\n\r\nThe streams of the low-lying areas are high in dissolved solids content. Sodium, bicarbonate, and sulfate are the predominant ions. The quality of the water varies during a single-flow event and season-ally. Streams in the mountains are low in dissolved solids content. \r\n\r\nRadiochemical constituents are fairly low in most of the natural streamflow, but concentrations are higher than in streams outside of the basin.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr791499","usgsCitation":"Busby, M.W., 1979, Surface water environment in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah: U.S. Geological Survey Open-File Report 79-1499, v, 64 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr791499.","productDescription":"v, 64 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":140546,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1499/report-thumb.jpg"},{"id":35728,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1499/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afbe4b07f02db6961c5","contributors":{"authors":[{"text":"Busby, Mark William","contributorId":67088,"corporation":false,"usgs":true,"family":"Busby","given":"Mark","email":"","middleInitial":"William","affiliations":[],"preferred":false,"id":157185,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":8123,"text":"ofr791500 - 1979 - Water use in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah","interactions":[],"lastModifiedDate":"2012-02-02T00:06:13","indexId":"ofr791500","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","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":"79-1500","title":"Water use in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr791500","usgsCitation":"Busby, M.W., 1979, Water use in the area of the San Juan Basin regional uranium study, New Mexico, Colorado, Arizona, and Utah: U.S. Geological Survey Open-File Report 79-1500, ii, 21 p. :maps ;28 cm., https://doi.org/10.3133/ofr791500.","productDescription":"ii, 21 p. :maps ;28 cm.","costCenters":[],"links":[{"id":142291,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1979/1500/report-thumb.jpg"},{"id":112905,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1979/1500/report.pdf","size":"602","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0de4b07f02db5fd179","contributors":{"authors":[{"text":"Busby, Mark William","contributorId":67088,"corporation":false,"usgs":true,"family":"Busby","given":"Mark","email":"","middleInitial":"William","affiliations":[],"preferred":false,"id":157186,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":1066,"text":"wsp1576J - 1979 - Availability and quality of ground water, southern Ute Indian Reservation, southwestern Colorado","interactions":[{"subject":{"id":8055,"text":"ofr77623 - 1977 - Availability and quality of ground water, Southern Ute Indian Reservation, southwestern Colorado","indexId":"ofr77623","publicationYear":"1977","noYear":false,"title":"Availability and quality of ground water, Southern Ute Indian Reservation, southwestern Colorado"},"predicate":"SUPERSEDED_BY","object":{"id":1066,"text":"wsp1576J - 1979 - Availability and quality of ground water, southern Ute Indian Reservation, southwestern Colorado","indexId":"wsp1576J","publicationYear":"1979","noYear":false,"chapter":"J","title":"Availability and quality of ground water, southern Ute Indian Reservation, southwestern Colorado"},"id":1}],"lastModifiedDate":"2012-02-02T00:05:18","indexId":"wsp1576J","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1979","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":341,"text":"Water Supply Paper","code":"WSP","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"1576","chapter":"J","title":"Availability and quality of ground water, southern Ute Indian Reservation, southwestern Colorado","docAbstract":"Population growth and the potential development of subsurface mineral resources have increased the need for information on the availability and quality of ground water on the Southern Ute Indian Reservation. The U.S. Geological Survey, in cooperation with the Southern Ute Tribal Council, the Four Corners Regional Planning Commission, and the U.S. Bureau of Indian Affairs, conducted a study during 1974-76 to assess the ground-water resources of the reservation. \r\n\r\nWater occurs in aquifers in the Dakota Sandstone, Mancos Shale, Mesaverde Group, Lewis Shale, Pictured Cliffs Sandstone, Fruitland Formation, Kirtland Shale, Animas and San Jose Formations, and terrace and flood-plain deposits. Well yields from sandstone and shale aquifers are small, generally in the range from 1 to 10 gallons per minute with maximum reported yields of 75 gallons per minute. Well yields from terrace deposits generally range from 5 to 10 gallons per minute with maximum yields of 50 gallons per minute. Well yields from flood-plain deposits are as much as 25 gallons per minute but average 10 gallons per minute. \r\n\r\nWater quality in aquifers depends in part on rock type. Water from sandstone, terrace, and flood-plain aquifers is predominantly a calcium bicarbonate type, whereas water from shale aquifers is predominantly a sodium bicarbonate type. Water from rocks containing interbeds of coal or carbonaceous shales may be either a calcium or sodium sulfate type. Dissolved-solids concentrations of ground water ranged from 115 to 7,130 milligrams per liter. Water from bedrock aquifers is the most mineralized, while water from terrace and flood-plain aquifers is the least mineralized. In many water samples collected from bedrock, terrace, and flood-plain aquifers, the concentrations of arsenic, chloride, dissolved solids, fluoride, iron, manganese, nitrate, selenium, and sulfate exceeded U.S. Public Health Service (1962) recommended limits for drinking water. \r\n\r\nSelenium in the ground water in excess of U.S. Public Health Service (1962) recommended limit of 10 micrograms per liter for drinking water occurs throughout the reservation but principally in the central part. Of the 265 wells and springs sampled, 74 contained water with selenium concentrations in excess of the recommended limit. Selenium concentrations exceeded 10 micrograms per liter principally in water from aquifers in the San Jose and Animas Formations. The maximum selenium concentration determined during the study was 13,000 micrograms per liter in a sample obtained from the San Jose Formation. The only known documented case of human selenium poisoning caused by drinking ground water occurred on the reservation.","language":"ENGLISH","publisher":"U.S. Govt. Print.

A review of chromatographic processes involved in the flow scheme is also presented. Organic analytes which appear in each aqueous fraction are quantified by dissolved organic carbon analysis. Hydrophobic organic acids in a water sample are concentrated on a porous acrylic resin. These acids usually constitute approximately 30-50 percent of the dissolved organic carbon in an unpolluted water sample and are eluted with an aqueous eluent (dilute base). The concentrate is then passed through a column of polyacryloylmorpholine gel, which separates the acids into high- and low-molecular-weight fractions. The high- and low-molecular-weight eluates are reconcentrated by adsorption chromatography, then are eluted with a pH gradient into strong acids (predominately carboxylic acids) and weak acids (predominately phenolic compounds). For standard compounds and samples of unpolluted waters, the scheme fractionates humic substances into strong and weak acid fractions that are separated from the low molecular weight acids. A new method utilizing conductivity is also presented to estimate the acidic components in the methanol fraction.","language":"ENGLISH","publisher":"U.S. Geological Survey : for sale by the Supt. of Docs., U.S. Govt.

One objective of the study was to assess the magnitudes, nature, and effects of point and non-point discharges in the Chattahoochee River basin from Atlanta to the West Point Dam. \r\n\r\nOn an average annual basis and during the storm period of March 1215, 1976, non-point-source loads for most constituents analyzed were larger than point-source loads at the Whitesburg station, located on the Chattahoochee River about 40 river miles downstream of Atlanta. Most of the non-point-source constituent loads in the Atlanta-to-Whitesburg reach were from urban areas. Average annual point-source discharges accounted for about 50 percent of the dissolved nitrogen, total nitrogen, and total phosphorus loads, and about 70 percent of the dissolved phosphorus loads at Whitesburg. \r\n\r\nDuring weekends, power generation at the upstream Buford Dam hydroelectric facility is minimal. Streamflow at the Atlanta station during dry-weather weekends is estimated to be about 1,200 ft3/s (cubic feet per second). Average daily dissolved-oxygen concentrations of less than 5.0 mg/L (milligrams per liter) occurred often in the river, about 20 river miles downstream from Atlanta during these periods from May to November. \r\n\r\nDuring a low-flow period, June 1-2, 1977, five municipal point sources contributed 63 percent of the ultimate biochemical oxygen demand, 97 percent of the ammonium nitrogen, 78 percent of the total nitrogen, and 90 percent of the total phosphorus loads at the Franklin station, at the upstream end of West Point Lake. Average daily concentrations of 13 mg/L of ultimate biochemical oxygen demand and 1.8 mg/L of ammonium nitrogen were observed about 2 river miles downstream from two of the municipal point sources. Carbonaceous and nitrogenous oxygen demands caused dissolved-oxygen concentrations between 4.1 and 5.0 mg/L to occur in a 22-mile reach of the river downstream from Atlanta. Nitrogenous oxygen demands were greater than carbonaceous oxygen demands in the reach from river mile 303 to 271, and carbonaceous demands were greater from river mile 271 to 235. The heat load from the Atkinson-McDonough thermoelectric power-plants caused a decrease in the dissolved-oxygen concentrations of about 0.2 mg/L. \r\n\r\nDuring a critical low-flow period, a streamflow at Atlanta of about 1,800 ft3/s, with present (1977) point-source flows of 185 ft3/s containing concentrations of 45 mg/L of ultimate biochemical oxygen demand and 15 mg/L of ammonium nitrogen, results in a computed minimum dissolved-oxygen concentration of 4.7 mg/L in the river downstream from Atlanta. In the year 2000, a streamflow at Atlanta of about 1,800 ft3/s with point-source flows of 373 ft3/s containing concentrations of 45 mg/L of ultimate biochemical oxygen demand and 5.0 mg/L of ammonium nitrogen, will result in a computed minimum dissolved-oxygen concentration of 5.0 mg/L. A streamflow of about 1,050 ft3/s at Atlanta in the year 2000 will result in a dissolved-oxygen concentration of 5.0 mg/L if point-source flows contain concentrations of 15 mg/L of ultimate biochemical oxygen demand and 5.0 mg/L of ammonium nitrogen. \r\n\r\nPhytoplankton concentrations in West Point Lake, about 70 river miles downstream from Atlanta, could exceed 3 million cells per milliliter during extended low-flow periods in the summer with present point- and non-point-source nitrogen and phosphorus loads. In the year 2000, phytoplankton concentrations in West Point Lake are not likely to exceed 700,000 cells per milliliter during extended low-flow periods in the summer, if phosphorus concentrations do not exceed 1.0 mg/L in point-source discharges.","language":"ENGLISH","publisher":"U.S. Govt.
