To protect salmon egg incubation habitat during the period of November 2 to April 30, a fish-water bypass was incorporated into the design of the dam to ensure a minimum discharge of 40 cubic feet per second in the lower river. This minimum flow determination was based on an open-water instream flow study that did not take into account effects of ice formation. A study was begun in March 1993 to determine winter flow conditions in the lower Bradley River. As a part of this study, data were collected at sites in the lower Bradley River to measure discharge, wetted perimeter, water depth, flow velocity, and specific conductance, as well as temperature and dissolved oxygen from both surface water and intragravel water.

In these technologies the site may be modified to enhance microbial activity, or may simply be monitored for naturally occurring microbial activity. In either case, an important aspect of site assessment for these technologies is to determine if the microorganisms present at the site have the potential to break down contaminants under the prevailing environmental conditions. We examined the numbers and activity of hydrocarbon-degrading microorganisms in ground water collected from petroleum-hydrocarbon contaminated and uncontaminated wells at the Railroad Industrial Area near Fairbanks, Alaska. We found that the population of gasoline-degrading microorganisms in ground water was correlated to the degree of contamination by benzene, toluene, ethylbenzene and xylenes (BTEX). We also found that these organisms could actively mineralize these types of compounds in laboratory mineralization assays. Increasing temperature and adding nutrients both enhanced the rate of mineralization in the laboratory, but measurable degradation still occurred under conditions similar to those found in the field. Dissolved oxygen in ground water at this site ranged from 0 to 3.6 milligrams per liter. Therefore, oxygen may not always be available to microorganisms as a terminal electron acceptor. Preliminary geochemical evidence from the field indicates that alternative electron acceptors such as Fe(III), sulfate, or nitrate may be used, contributing to degradation of contaminants at this site.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr98287","issn":"0566-8174","usgsCitation":"Braddock, J.F., Catterall, P.H., and Richmond, S.A., 1998, Assessment of the potential for biodegradation of petroleum hydrocarbons in the Railroad Industrial Area, Fairbanks, Alaska: U.S. Geological Survey Open-File Report 98-287, iv, 10 p. :ill., maps ;28 cm.; 5 illus.; 6 plates; 5 tables, https://doi.org/10.3133/ofr98287.","productDescription":"iv, 10 p. :ill., maps ;28 cm.; 5 illus.; 6 plates; 5 tables","costCenters":[],"links":[{"id":153724,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1998/0287/report-thumb.jpg"},{"id":51180,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1998/0287/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ee4b07f02db660a49","contributors":{"authors":[{"text":"Braddock, Joan F.","contributorId":97934,"corporation":false,"usgs":true,"family":"Braddock","given":"Joan","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":184922,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Catterall, Peter H.","contributorId":52606,"corporation":false,"usgs":true,"family":"Catterall","given":"Peter","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":184921,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Richmond, Sharon A.","contributorId":29005,"corporation":false,"usgs":true,"family":"Richmond","given":"Sharon","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":184920,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The Lake Valley ACEC is along the southeastern margin of the Black Range of western Sierra County, New Mexico. The Black Range contains eleven mining districts from which silver, lead, zinc, manganese, copper, gold, and tin have been recovered. As part of the study, an area of over 75 square mi (195 square km) in the area of the Lake Valley ACEC was mapped to understand ore controls and to assess mineral-resource potential. Lake Valley mining district is in Mississippian Lake Valley Formation carbonate rocks, but much of the surrounding terrane consists of volcanic rocks on the southeastern edge of the Emory cauldron which formed about 34.9 Ma. Volcanic rocks are part of the Mogollon-Datil volcanic province which include flows, breccias, ash-flow tuffs, and intrusive rhyolites. The Lake Valley mining district is located about 20 mi (32 km) south of the Late Cretaceous Laramide copper-gold porphyry intrusion at Hillsboro. It is also located at the western boundary of the Rio Grande rift basin.The Lake Valey fault is the major structural feature of the study area. Geological and geophysical data suggest the fault is composed of two segments: a southern, northwest-striking segment that may have a pre-Tertiary history and a northerly-striking segment that is part of the Emory cauldron ring fracture. The mining district is bounded by the southern, northwest-striking segment of the fault which may have up to 800 ft (240m) of normal offset. Deposit types identified in the Black Range, and for which we assess mineral potential, are Laramide porphyry, Laramide skarns, Laramide veins, gold placer, carbonate-hosted, volcanic-epithermal, and rhyolite tin; no Rio Grande Rift baritefluorite-galena deposits are known, but they are included in the assessment. The most likely deposits to be discovered in the Lake Valley district are carbonate-hosted silver-manganese deposits. These deposits could be deposited by hydrothermal fluids or be related to intrusion of Oligocene rhyolite or Laramide porphyry. An aeromagnetic high south of the district probably reflects a small felsic intrusion of unknown age. We assess the Lake Valley ACEC as having low to moderate potential for undiscovered carbonate-hosted deposits associated with volcanic rocks or Laramide porphyry plutons, and low potential for gold placer and rhyolite tin deposits.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr98347","usgsCitation":"Nutt, C., O’Neill, J., McLemore, V., Lindsey, D.A., Ratte, J., Hedlund, D.C., Klein, D.P., and Kleinkopf, M.D., 1998, Geology and mineral resources of the Lake Valley area, Sierra County, New Mexico: U.S. Geological Survey Open-File Report 98-347, Report: 70 p.; 1 Plate: 34.99 x 42.51 inches, https://doi.org/10.3133/ofr98347.","productDescription":"Report: 70 p.; 1 Plate: 34.99 x 42.51 inches","costCenters":[],"links":[{"id":153574,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1998/0347/report-thumb.jpg"},{"id":399846,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1998/0347/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":399847,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1998/0347/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"scale":"24000","country":"United States","state":"New Mexico","county":"Sierra County","otherGeospatial":"Lake Valley area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -107.6381,\n              32.875\n            ],\n            [\n              -107.5,\n              32.875\n            ],\n            [\n              -107.5,\n              32.6928\n            ],\n            [\n              -107.6381,\n              32.6928\n            ],\n            [\n              -107.6381,\n              32.875\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b471c","contributors":{"authors":[{"text":"Nutt, C.J.","contributorId":52577,"corporation":false,"usgs":true,"family":"Nutt","given":"C.J.","email":"","affiliations":[],"preferred":false,"id":185866,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Neill, J.M.","contributorId":85562,"corporation":false,"usgs":true,"family":"O’Neill","given":"J.M.","email":"","affiliations":[],"preferred":false,"id":185867,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"McLemore, V.

This requires a quantifiable understanding of ground-water flow through the surficial aquifer system and how the system will respond to any future stresses. The geologic units of interest in the study area consist of sediments of Holocene to Miocene age that extend from land surface to the base of the Hawthorn Group. The hydrogeology within the study area was determined from gamma-ray and geologists? logs. Ground-water flow through the surficial aquifer system was simulated with a seven-layer, finite-difference model that extended vertically from the water table to the top of the Upper Floridan aquifer. Results from the calibrated model were based on a long-term recharge rate of 6 inches per year, which fell in the range of 4 to 10 inches per year, estimated using stream hydrograph separation methods. More than 80 percent of ground-water flow circulates within the surficial-sand aquifer, which indicates that most contaminant movement also can be expected to move through the surficial-sand aquifer alone. The surficial-sand aquifer is the uppermost unit of the surficial aquifer system. Particle-tracking results showed that the distances of most flow paths were 1,500 feet or less from a given site to its discharge point. For an assumed effective porosity of 20 percent, typical traveltimes are 40 years or less. At all of the sites investigated, particles released 10 feet below the water table had shorter traveltimes than those released 40 feet below the water table. Traveltimes from contaminated sites to their point of discharge ranged from 2 to 300 years. The contributing areas of the domestic supply wells are not very extensive. The shortest traveltimes for particles to reach the domestic supply wells from their respective contributing areas ranged from 70 to 200 years.

As urban area expand, local sources of these resource are becoming inaccessible (gravel cannot be mined from under a subdivision, for example), or the cost of recovery of the resource becomes prohibitive (oil and gas drilling in urban areas is costly), or the resources may become unfit for some use (pollution of ground water may preclude its use as a water supply). Governmental land-use decision and environmental mandates can further preclude development of natural resources. If infrastructure resources are to remain economically available. current resource information must be available for use in well-reasoned decisions bout future land use. Ground water is an infrastructure resource that is present in shallow aquifers and deeper bedrock aquifers that underlie much of the 2,450-square-mile demonstration area of the Colorado Front Range Infrastructure Resources Project. In 1996, mapping of the area's ground-water resources was undertaken as a U.S. Geological Survey project in cooperation with the Colorado Department of Natural Resources, Division of Water Resources, and the Colorado Water Conservation Board.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/fs11398","usgsCitation":"Robson, S.G., and Heiny, J.S., 1998, Front Range Infrastructure Resources Project: water-resources activities: U.S. Geological Survey Fact Sheet 113-98, 4 p., https://doi.org/10.3133/fs11398.","productDescription":"4 p.","numberOfPages":"4","costCenters":[],"links":[{"id":139708,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs11398.jpg"},{"id":285395,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/fs/0113-98/report.pdf"}],"country":"United States","state":"Colorado","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -105.5027,39.2894 ], [ -105.5027,40.7259 ], [ -104.452,40.7259 ], [ -104.452,39.2894 ], [ -105.5027,39.2894 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b4472","contributors":{"authors":[{"text":"Robson, Stanley G.","contributorId":73187,"corporation":false,"usgs":true,"family":"Robson","given":"Stanley","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":152936,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Heiny, Janet S.","contributorId":93468,"corporation":false,"usgs":true,"family":"Heiny","given":"Janet","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":152937,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Long-term method detection levels (LT-MDLs) for MTBE, TAME, DIPE, and ETBE ranged from 15 to 83 nanograms per liter (0.015 to 0.083 microgram per liter). Nanogram-per-liter-concentration detections are reported if all of the identification criteria are met, whereas previous methods censored detections at a pre-determined method reporting level. The reporting level for this method is defined as two times the LT-MDL, does not censor detections at less than this concentration, and is referred to as the nondetection value (NDV). Bias and variability data from multiple analyses, analysts, and instruments over a 60-day period show the oxygenate recoveries ranging from 100 to 109 percent, with 6 to 8 percent relative standard deviation.

Modern horizontal long period seismometers with their long natural periods are incredibly sensitive to tilt. They can sense tilts smaller than <span>10</span><sup>-11</sup> radians. To most readers, this is just a very very small number, so we will begin with an example, which should help to illustrate just how small 10<sup>-11</sup> radians is.</p><p>Suppose we have an absolutely rigid rod which is approximately 4170 kilometers long; this just happens to be the Rand McNally map scaled crow flight distance between Los Angeles and Boston. Tilting this rod <span>10</span><sup>-11</sup> radians corresponds to raising one end of the rod 0.0000417 meters. Alas, this is just another very very small number! However, this corresponds to slipping a little less than one third a sheet of ordinary copying paper under one end of this perfectly rigid rod. To clarify, we mean, take a sheet of paper just like the paper this report is printed on and split it a little less than one third in the thickness direction, then put it under the end of the 4170 kilometer long rod! This will tilt the rod <span>10</span><sup>-11</sup> radians.</p><p>Real world seismometers are nowhere near the length of this rod. A KS-54000 is about two meters long. Tilting a rod only two meters long 10~n radians corresponds to moving one end of this rod a mere 0.00000000002 meters or 0.02 millimicrons. As one of the authors old math teachers used to say, \"That's PDS\" (PDS = Pretty Damn Small). Unfortunately, the long period seismologist does not have the luxury of ignoring PDS numbers when it suits him as the mathematician frequently does. He must live in the real world in which tilts this small create severe contamination of long period seismic data.</p><p>At periods longer than 20 seconds, tilt noise contaminates the long period data from all instruments installed on or near the earth's surface. Many years of experimentation revealed that installing the sensors at depth in deep mines drastically reduced the level of tilt noise in long period data. However, low levels of tilt noise persisted even at great depth; this noise was caused by air convection in the vault in which the sensors were installed. Over the years, methods were developed to control the air motion with mechanical barriers (boxes) around the sensors and by stratifying (creating a situation in which the air temperature increases with height) the air in the vault near the seismometer. These methods decreased tilt noise in deep mines to very low levels. However, deep mines, that are economically and environmentally suitable and accessible to seismology, are not plentiful and are not evenly distributed over the earth's surface. Therefore, the borehole deployable Teledyne Geotech KS-36000 and later the KS-54000 sensor systems were developed to fulfill the need for instruments that could be installed at depth wherever high quality long period data was desired. Early in the development program, it became evident to the Teledyne Geotech personnel that air convection within the borehole was going to be a significant problem in KS deployments. Experimental and theoretical investigations conducted by Teledyne Geotech (see Douze and Sherwin, 1975, and Sherwin and Cook, 1976) produced a list of recommended installation procedures for reducing the effects of air convection. These procedures consisted of wrapping the sensor in a relatively thin layer of foam insulation, filling the free space volume in the vicinity of the centralizer-bail assembly with foam insulation, and the installation of styrofoam hole plugs immediately above the cable strain relief assembly at the top of the sensor package and at the top of the borehole. This technology has performed quite satisfactorily for over 20 years but evidence of tilt noise in the system output has persisted throughout the KS deployment program (the evidence was that the horizontal components were usually noisier than the vertical components) even in deep boreholes. Some deep borehole sites have been plagued by quite high levels of horizontal noise. Therefore, there has been a definite need for a new technique for controlling low level tilt noise in deep boreholes and the use of sand has been under consideration for several years.</p><p>Figure 1 contains conceptual illustrations of both the conventional holelock installed KS sensor system and the same sensor installed in sand. This figure demonstrates the major differences between the two installation methods. The curved arrows in the borehole on the left in the figure denote possible air convection cells which are believed to be the source of tilt noise in some of the conventional installations. This air motion is eliminated in a sand installation by filling most of the free air volume surrounding the seismometer with sand as shown in the right hand portion of the figure. The sand actually performs two functions; it prevents air motion and provides a remarkably ridgid clamping of the seismometer in the borehole. </p><p>This report presents the results of quantitative experimental investigations into the effectiveness of controlling low level air convection in seismic borehole installations with sand. The main body of the experimental effort consisted of installing two KS-540001 sensor systems in closely spaced shallow boreholes, allowing the sensors to reach equilibrium operation, and then pouring sand into both boreholes to observe any changes caused by pouring sand into the holes. The hypothesis of the experiment was that the sand would fill up the entire free air volume between the sensor package and the borehole walls thereby preventing movement of the air in the vicinity of the sensor package. The validity of this hypothesis had been qualitatively proven by earlier experiments at ASL and by the sand installations at the IRIS/ASL stations ANMO in 1995 and COLA in 1996.

Waggoner Map","docAbstract":"The geologic map of the Rosalia 1:100,000-scale quadrangle was compiled in 1990 by S.Z. Waggoner of the Washington state Division of Geology and Earth Resources. This data was entered into a geographic information system (GIS) as part of a larger effort to create regional digital geology for the Pacific Northwest. The intent was to provide a digital geospatial database for a previously published black and white paper geologic map. This database can be queried in many ways to produce a variety of geologic maps. Digital base map data files are not included: they may be obtained from a variety of commercial and government sources. This database is not meant to be used or displayed at any scale larger than 1:100,000 (e.g., 1:62,500 or 1:24,000) as it has been somewhat generalized to fit the 1:100,000 scale map. \r\n\r\nThe map area is located in eastern Washington and extends across the state border into western Idaho. This open-file report describes the methods used to convert the geologic map data into a digital format, documents the file structures, and explains how to download the digital files from the U.S. Geological Survey public access World Wide Web site on the Internet. \r\n\r\nWe wish to thank J. Eric Schuster of the Washington Division of Geology and Earth Resources for providing the original stable-base mylar and the funding for it to be scanned. We also thank Dick Blank and Barry Moring of the U.S. Geological Survey for reviewing the manuscript and digital files, respectively.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/ofr98357","issn":"0566-8174","collaboration":"Prepared in cooperation with the Spokane County Public Works, Utilities Department, and the Washington Division of Geology and Earth Resources","usgsCitation":"Derkey, P., Johnson, B.R., Lackaff, B.B., and Derkey, R.E., 1998, Digital Geologic Map of the Rosalia 1:100,000 Quadrangle, Washington and Idaho: A Digital Database for the 1990 S.Z.
